The Physics of Striking

In healthy adults the brainstem hand-blink reflex is enhanced when the hand enters the face's defensive peripersonal space (S2); the enhancement follows a step function of proximity over a half-ellipsoid on the face (S3, model); it appears only when a stimulus is expected on the near hand and is suppressed when a thin wooden screen stands between hand and face, a screen that changes no afferent input (S1); in 13 boxers against 13 naive adults the near-face enhancement is suppressed in a static guard-like position, more with more years of boxing, and returns when the hand moves (S4). Population: healthy adults and boxers; outcome: reflex magnitude by EMG; class: intervention (within-person manipulation) with one cross-sectional expert contrast. Boundary: a proxy reflex to electrical stimulation, not a measured response to a punch; the boxer effect is a dose correlation, not a training assignment.

A subcortical defensive circuit is gated by a cortical estimate of where harm can arrive and what covers it; the estimate is written by expected stimulus probability, hand-face geometry and the presence of a barrier, and a learnt protective posture becomes one of its inputs. Because this layer fires before any appraisal exists, subjective panic cannot cause the first defensive action; it can only shape the ones that follow.

The page's sentence that the body wants to panic cannot stand as physiology; the honest sentence is that the body mounts a fast defensive response whose strength it sets by predicted distance and cover, and that a guard turns the reflex down.

The first defence against a strike at the head fires in the brainstem before any fear exists, and its strength is set by how close the strike is predicted to land and what covers the face; a trained guard turns it down. Panic, the slow appraisal layer, therefore cannot cause the first defensive act. The gate flagged one of this axiom's sources as misquoted, so it is a lead for the page rather than a load-bearing sentence; the page's own 'your body wants to panic' stays under test until a clean-sourced pass, and the alarm's persistence is carried at higher weight by the training composure vector's A1.

Mental stress raised VO2 by 20 percent of the resting rate in 11 lean women under a clamp, and propranolol abolished the rise in 6 restudied women (S5, intervention, 2000); energy expenditure was 1.3 times rest during mental arithmetic in 44 male students (S6, 2007); cardiac output during stress substantially exceeded the value predicted from each person's own exercise calibration at the same oxygen uptake, in young men measured by Doppler and mass spectrometry (S7, 2009; S8, 22 men, 2010); at a matched running speed of 7.3 km/h a 5 m height threat added 65 mL/min of VO2 (95 percent CI 7.1 to 123.5), about 3 percent of the running uptake, and 4.1 bpm in 19 adults (S9, 2014). Populations: resting women, students, young men, recreational adults; outcomes: VO2, cardiac output, heart rate; classes: intervention and within-person manipulation. Boundary: no study measured oxygen uptake while strikes arrived (S12 states the mask cannot be worn in a contest); the stressors were arithmetic, speech and height, not punches; additivity of the fear cost onto a fighting workload is assumed.

The sympathetic response is beta-adrenergic and its cardiac arm is sized for anticipated work rather than the work being done, so cardiac output and heart rate rise out of proportion to oxygen flux; by the Fick relation heart rate alone cannot fix VO2 because stroke volume and extraction also move, and under stress the calibration between heart rate and energy that holds during exercise breaks.

Any sentence on the page that reads pulse or adrenaline as an energy bill is wrong; the fear itself costs about a fifth to a third more than sitting still.

Mental stress at rest adds a modest increment to oxygen uptake while the heart runs well above what that uptake predicts, so pulse and adrenaline overstate the energy a frightened body spends. The whole vector was clamped for misquoted sources, so the increment is reported as this run read it, not as settled; the direction, the heart as a false energy meter, is also carried by the threat response under strikes vector's A5 and by the training composure vector's A5 on heart-rate variability.

The Compendium of Physical Activities codes moderate-pace martial arts (judo, karate, kick boxing, tae kwon do, Muay Thai boxing) at 10.3 METs, boxing sparring 7.8 and boxing in a ring 12.8, where 1 MET is the seated 3.5 mL O2/kg/min convention (S10, 2011); 11 elite boxers ran above 90 percent of VO2max in every round of a simulated 3 x 3 min contest, about 15 METs for a VO2max near 55 mL/kg/min (S12, 2018); a 3 x 2 min semicontact bout cost about 680 kJ over its 8 minutes in 10 boxers, 77 percent aerobic, which is about 85 kJ/min against a conventional resting 5.2 kJ/min for 70.6 kg, about 16 times rest (S13, 2014; ratio derived from the paper's totals); fear alone adds 0.2 to 0.3 METs (S5, S6) and threat at matched work about 3 percent (S9). Excess of the fight over rest about 14 METs, excess of the fear about 0.2 to 0.3 METs, a share of about 1.4 to 2 percent. Populations: amateur and elite boxers, resting adults; outcomes: VO2 and total metabolic energy; classes: within-person measurement, compendium codes, intervention for the fear term. No leg located a source for a panic-specific tenfold figure.

Energy conservation puts the fight's bill in the legs, trunk and fists: external work, braking, posture and co-contraction consume oxygen at ten to fifteen times rest over a round, while the affective response, acting through beta-adrenergic thermogenesis and cardiac work, adds a few tenths of a MET; attributing the fight's bill to the fear is a category error between a workload ratio and a threat increment.

The page may keep a ten-times sentence only about the work of fighting against rest, never about panic; the panic sentence is refuted.

The tenfold figure's only located provenance is an activity code for martial arts against seated rest, a workload number, and the fear's share of a fight's excess is a small fraction of it; no leg found a panic-specific source after repeated searches. Because the vector's sources tripped the gate, the page may not keep even a rewritten ten-times sentence on this run's authority; the page's panic sentence falls regardless, since its only support was itself.

Measured resting VO2 averaged 2.6 +/- 0.4 mL/kg/min in 642 women and 127 men by ventilated-hood calorimetry, so the 3.5 convention overstates resting oxygen uptake by 35 percent and resting energy by 20 percent on average (S11, 2005, correlational measurement); muscle ATP turnover can rise more than 100-fold from rest to maximal exercise, phosphocreatine is mostly spent in 10 to 15 s and glycolysis is acid-limited within 30 to 90 s (S14, 2020 review); over one 3-minute round the whole-body ratio is about 15 (S12) and over an 8-minute bout with breaks about 16 (S13). Population: heterogeneous adults, elite and amateur boxers; outcomes: resting VO2, ATP turnover, bout energy. Boundary: muscle figures are per kilogram of muscle, not whole body; the Compendium and the bouts use the 3.5 convention.

A ratio is a property of an integration window and a reference state, not of a condition: the same body yields 1.3 (fear at rest), 15 (a round) or over 100 (one exchange at the muscle) depending on what is divided by what over how long, and pulmonary gas exchange cannot see the stored phosphocreatine term over seconds, so a seconds-scale expenditure is not even measurable by the instrument the convention assumes.

A number on the page must say times what, over what interval; 'ten times the normal rate' with no denominator is not a number and may not stay as written.

A metabolic ratio means nothing until its denominator (a measured resting rate or the seated convention) and its window (a round, a bout, one exchange) are fixed; the same body yields ratios near one, in the teens, or far higher at the muscle depending on both. This is the estimand law that the strike force and impact vector's A5, the defense as distance and time vector's A1 and the brain under head impact vector's A2 state for force, strike duration and impact counts, and it is the rule under which the page's 'ten times the normal rate' is not a number.

Plasma epinephrine rose from 702 at baseline to 1,871 after kata and 3,269 pmol/L after 3 min of kumite in 10 competitive karate athletes, a 4.7-fold concentration ratio sampled within 10 minutes after, with no oxygen measurement (S15, 2012, randomised crossover); under mental stress VO2 rose 20 percent while cardiac output rose 25 percent and exceeded its oxygen-predicted value (S5, S7); the mean task heart rate across a shoot-or-withhold task under shock threat was 68.5 bpm in 76 participants, with threat producing preparatory slowing then action acceleration rather than sustained tachycardia (S16, 2019); the On Combat claim that fighters are exhausted because they burned all their adrenaline (S26, argument) is physically impossible. Populations: karate athletes, resting adults, civilians and police recruits; outcomes: plasma catecholamines, VO2, cardiac output, heart rate; classes: intervention and within-person measurement, one argument source audited.

A plasma concentration is secretion minus clearance over a distribution volume, not a flux of fuel; catecholamines circulate at nanomolar levels and their oxidation yields no usable energy, so a doubled or quintupled signal implies neither a doubled energy flux nor an emptied tank; heart rate is a control signal moved by sympathetic drive and cardiac loading, and a given rate means different things depending on why it arrived.

The page may say threat floods the blood with adrenaline and drives the heart; it may not say that is where the energy goes or that adrenaline runs out.

Catecholamine concentration and heart rate are signals, not fuel; 'burned all his adrenaline' is physically impossible. Carried at reduced weight because its source audit found a number not on the page; the page may say threat floods the blood and drives the heart, never that this is where the energy goes. It belongs with the training composure vector's A5 and the brain under head impact vector's A4 in the law that a readout is not the quantity behind it.

Against an opponent firing soap cartridges, 7 police officers lost shooting accuracy while acting faster, making themselves smaller and blinking more (S17, 2010); with a shoot-back cannon on, 36 officers shot more often at surrendering suspects, lost shot accuracy and responded faster to armed suspects while gaze behaviour was unaffected (S18, 2012); in 22 civilians and 54 recruits threat produced opposing accuracy effects, better when shooting was required and more withholding errors on phone trials (S16, 2019); in 22 soldiers anxiety reduced shooting accuracy, decision making and arithmetic, exercise-raised arousal prevented the shooting decrement, and soldiers more often failed to shoot when fired at (S22, 2014); in 9 soccer players exercise at adrenaline threshold and at maximal power left decision accuracy unchanged and made decisions faster than at rest (S20, 1999); attentional control theory predicts efficiency fails before effectiveness through inhibition and shifting (S19, 2007). Populations: police officers and recruits, civilians, infantry soldiers, college athletes; outcomes: accuracy, speed, response bias, gaze; classes: within-person manipulations and one theory. Boundary: firearms use-of-force tasks, not strikers; samples of 7 and 36 in the two officer studies; effects are task-specific and cannot be averaged into one 'thinking' score.

Threat first raises the cost of a decision and shifts what the system optimises: speed over accuracy, a criterion biased toward acting because a missed attack is costly, and a range policy that treats the opponent as closer; inhibition and shifting pay first while perception and prepared action largely survive, so a missed defense cannot identify which stage failed and overall accuracy cannot separate a criterion shift from lost discrimination.

'Panic destroys your ability to think' is bounded to 'threat makes thinking dearer and pushes it toward speed, action and the threat axis'; the page may describe what shifts, not a destruction.

Threat shifts how a trained person acts (faster, a looser criterion, a contracted sense of range) before it lowers what they can do; accuracy fell, held or rose depending on the task. This is the bound on 'panic destroys your ability to think', and it pairs with the training composure vector's A2 on the decision criterion. Its populations are shooters, not strikers, and the vector's sources were clamped, so it gives the page a direction, not a quoted result.

Across 113 shootings recalled by 80 officers, tunnel vision was reported in 51 percent of incidents, heightened visual detail in 56 percent, both in 15 percent, auditory blunting in 82 percent, heightened hearing in 20 percent and slow motion in 56 percent (S23, 2006, retrospective interviews, denominators are incidents); under return fire 7 officers blinked more and spent more time with eyes closed (S17, 2010); under anxiety 36 officers' gaze behaviour was unaffected while decisions shifted toward threat-based inference (S18, 2012); a fearful-face cue improved contrast sensitivity at the cued location in laboratory adults (S21, 2006, intervention, non-combat). Populations: police officers, laboratory adults; outcomes: recalled distortions, blink and gaze measures, contrast sensitivity. Boundary: the field figures are memories of a shooting, not measurements during it, and prevalence of tunnel vision moves between about 51 and 79 percent across surveys; none of these studies measured what the officer could see.

When heightened detail and tunnel vision are reported at near-equal rates in the same incidents, the visual system is re-weighting bandwidth toward the threat rather than failing; the sampling policy changes (shorter dwell, more blinks) and the cost falls only on information off the threat axis, which is the perceptual face of the same gain controller that sets reflex strength.

The page may say attention narrows onto the threat; it may not say perception shuts down or quote a percentage of vision lost.

Narrowing under threat is a reallocation of attention toward the threat, documented by recall after the event and co-occurring with heightened detail at the threat; it records an experience, not a measured loss of sight. The page may say attention narrows onto the threat; it may not quote a share of vision lost or say perception shuts down.

The 1997 Siddle-Grossman chart places complex-skill breakdown above 145 bpm and cognitive collapse above 175 bpm, names no experiment, and exempts exercise-induced heart rate (S24, argument; S26); a trainer's published critique quotes Lewinski that the idea a high heart rate alone causes loss of fine motor skills is a myth (S25, argument); 11 elite boxers held peak heart rate at or above 90 percent of maximum in every round while executing the full striking and defending repertoire of a simulated contest (S12, 2018); the shoot-or-withhold task ran at a mean heart rate of 68.5 bpm and threat still shifted accuracy and speed in 76 participants (S16, 2019); exercise-raised arousal prevented rather than caused the anxiety-driven loss of shooting accuracy in 22 soldiers (S22, 2014). Populations: elite boxers, civilians and recruits, infantry soldiers; outcomes: heart rate beside skill, accuracy and decisions. Boundary: no study has run strikers at 190 bpm through a decision battery mid-round; the refutation is of the chart's causal reading, not of a claim that extreme arousal never impairs.

The same heart rate means different things depending on why it arrived, which the chart concedes by exempting exercise; a variable that must be re-labelled by its cause before it predicts anything is a correlate, not a cause, and the causal variables are the threat appraisal and the attentional policy, not beats per minute.

No beats-per-minute threshold may appear on the page as physics.

The heart-rate bands sold as thresholds of collapse have no experiment behind them; skilled perceptual-motor work proceeds near maximal heart rate and threat effects on decisions appear at resting rates. No beats-per-minute figure belongs on the page as physics, whatever a clean-sourced pass later establishes for the rest of this vector.

In police officers trained under a shoot-back opponent (27 officers, four weekly one-hour sessions, 48 rounds; S1), shooting accuracy that fell under threat at pretest no longer fell at posttest and still held at a four-month retention test, while anxiety, heart rate and rated effort stayed elevated under high threat at every time point. In 66 officers (S4), both imagery groups kept accuracy under threat while mean anxiety, heart rate and mental effort were uniformly higher in all groups and the control's accuracy fell. In military survival training (S16, S17), the more resilient Special Forces trainees showed higher, not lower, neuropeptide-Y and norepinephrine under interrogation stress and returned to baseline by 24 hours while non-SF trainees stayed below it. No opened source at any dose shows the threat response eliminated. Boundary: police and military use-of-force populations; outcomes are motor accuracy and biomarkers; INTERVENTION (S1, S4) and CORRELATIONAL (S16, S17); no Thai fighter in a ring was measured.

Anxiety loads the goal-directed attentional system and lets the stimulus-driven system pull attention toward threat (S30). Training changes where attention is spent and how much effort is paid, so output holds while the alarm runs; observed calm is an effectiveness reading blind to the efficiency cost paying for it (S30, S1). The elite phenotype is a larger, better-shaped, faster-recovering alarm, not a smaller one (S16).

The page's verb 'override' fails: training does not switch the response off, it keeps the hands and the read working while it runs. A rewritten sentence can say training lets a person keep acting while the body stays alarmed; it cannot say the response is overridden.

The one durable finding on training under threat: output is preserved while anxiety, heart rate and effort stay elevated, and the protection held months later. It survived the cross-lab adversary and is the load-bearing replacement for the page's verb 'override': training lets a person keep acting while the body stays alarmed. It pairs with the skill decay and return vector's A7, which reads the same police cohort as extinction learning, and with the threat response under strikes vector's A6 on the policy shift.

Under a shoot-back cannon (S3), officers shot more often at suspects who were surrendering, shot faster when a gun was present and shot less accurately, with gaze behaviour unchanged by anxiety: they acted on threat-related inference rather than on what they were looking at. After three consecutive weeks of shooting-decision practice in four practice groups (S2: 57 officers), anxiety and false-positive shots under high threat were as large at posttest as at pretest in every group. In a realistic lethal-force scenario (S18: 122 active-duty officers, CORRELATIONAL), mean performance was 59 percent of the scored items, at least one lethal-force error occurred in 27 percent of officers, greater stress reactivity predicted poorer performance and years of service did not remove the effect. Boundary: police use-of-force decision tasks in which the judged person is the threat source; outcome is decision accuracy and false positives. Opposing row: under threat of electric shock in a military friend/foe task (S19), arousal rose and decision time and confidence changed but response sensitivity and bias did not, and stimulus uncertainty mattered more than the stressor; the criterion shift is documented when the stimulus to be judged is itself the source of the threat, not when the threat is an unrelated shock.

A criterion shift is a change in how much evidence is needed to act, not a loss of perception: gaze and distance judgments stay intact while the threshold at which an approach counts as an attack drops (S3, S30). Practice that rehearses the motor act under threat protects execution (Axiom 1) and leaves the prior on danger untouched, because the prior is set by the threat itself.

Composure cannot be the whole discipline because the component threat damages most, the read of what an approach is, is the one practice rescues least. A page sentence may say training protects what the hands do under fear far more than it protects the judgment of what is coming.

The decision criterion, what counts as enough evidence to act, moves under threat and did not move back after weeks of practice, while the hands did. The adversary refuted the strong form and the vector's dead links kept its citations below the floor, so it stands as a lead: the page may say training protects what the hands do more than the judgment of what is coming, flagged for re-verification.

In 84 police officers trained in knife defence (S7), the arm trained with added stressors (n=51) reported more stress and effort than the control arm (n=33), yet both arms improved on every rated performance variable in reality-based scenarios (all p<.05) and the stressors added no measurable gain. Across pressure-training trials pooled in S9, long doses had the smallest effect on performance under pressure. Across 37 studies and 1,837 participants (S8), stress inoculation reduced state and performance anxiety and improved performance under stress, with anxiety effects larger than performance effects. Stress training generalised across a change of stressor and of task only when the new task had itself been instructed (S10); consistent training environments raised efficiency and an inconsistent test environment disrupted it (S37); variable practice served transfer to a novel condition and specific practice served retention (S33); affordance similarity, not intensity, predicted transfer between sports (S34). Boundary: police (S7), laboratory learners (S10, S33, S37), pooled sport and tactical trials (S8, S9); outcomes are rated scenario performance, task accuracy and anxiety; INTERVENTION throughout. No trial randomised sparring dose and tested a first unfamiliar assault; that estimand is empty.

What a learner retrieves under load is the solution rehearsed under the same information and affordances; a stressor that shares nothing with the test adds arousal without adding retrievable structure (S10, S34, S30). Repeated sparring with one partner maximises retention of a partner-specific solution and minimises the variability that buys transfer (S33); uncalibrated exposure also inflates expectations of future stressors (S35).

'More and harder sparring builds more composure' has no dose-response support; the active ingredient is graded, representative, varied practice with a rehearsed strategy attached. A page may say composure learned against one partner is a solution to that partner.

Transfer follows shared elements and representative structure, not stressor intensity; added stressors and long hard doses were the weakest levers in the opened trials. Refuted by the adversary as a universal and held below the citation floor, so it is a bound to test, not law; it is the reason 'you fight how you train' gets a measured shape instead of staying a slogan, and the reason 'harder sparring builds composure' has no dose-response support here.

When healthy adults face the same psychosocial stressor on consecutive days, about two-thirds habituate their cortisol response (S20, review of repeated-measures designs) while cardiovascular reactivity shows little or no habituation; in one repeat design (S21) cortisol habituated between sessions 24 hours apart and a renewed challenge ten weeks later activated the axis as if new, and across a four-month interval endocrine habituation did not occur while subjective responses habituated faster. In rodents, an axis habituated to a chronic homotypic stressor shows a facilitated, larger response to a novel heterotypic one (S22, S23). In 1,837 pooled participants (S8), anxiety outcomes moved more than performance outcomes. Expertise did not abolish threat cost: 66 officers with more martial-arts experience performed better under threat yet still deteriorated relative to their own low-threat baseline (S31). In 103 elite kickboxers (S36, self-report, the one combat-sport row), arousal control and confidence went with challenge appraisal and worry with threat appraisal and poorer self-rated performance: appraisal, not suppression, is what the athletes report regulating. Boundary: human data are psychosocial laboratory stressors, not sparring; the heterotypic facilitation is rodent and is INFERENCE when applied to an unfamiliar opponent; S31 and S36 are correlational. By the same law, The Physics of Flow States (February 2026) reports arousal regulation in non-combat performers: heterotypic evidence relative to attack, with no presumptive transfer to it.

Habituation is non-associative learning keyed to the known parameters of a stimulus (partner, room, rules, the guarantee it stops); the endocrine layer quiets to the familiar, the cardiovascular layer barely does, and the subjective layer quiets fastest, so a person can feel composed in a familiar room on a measurement that does not travel (S20, S21, S22).

Gym composure against known partners is, by construction, a homotypic adaptation; a page may say calm in the gym is calm with those people in that room, and should not say it is calm under attack by a stranger.

Habituation is bound to the stimulus that produced it, partial across the body's systems and lost within weeks; the felt sense of calm habituates first and travels least. It survived the adversary and is this run's bound on The Physics of Flow States by name: arousal regulation in non-combat performers is heterotypic evidence relative to attack and carries no presumptive transfer. the skill decay and return vector's A7 states the same law from fear-extinction evidence as renewal and spontaneous recovery.

In a police critical-incident simulator (S12, randomized pairs), the tactical-breathing group scored higher on rules-of-engagement and communication and the gain was not associated with lower self-reported stress. In 12 special-response officers randomized to a three-day package of breathing with biofeedback, education, imagery and scenarios (S5), warehouse-scenario correct decisions averaged 3.83 of 4 against 2.33 of 4 for controls, while heart-rate advantages were not significant in both scenarios. In 57 officers given HRV biofeedback during lethal-force scenarios (S6), errors fell and stayed down at 12 months while maximum heart rate relative to rest rose from pre to post. In 100 student officers (S13), tactical breathing raised the first shot by 1.9 points of a 10-point shot score at 10 m with no difference on the easier later shots. In 38 officers after anaerobic fatigue (S14), about 45 seconds of breathing changed nothing: not accuracy, decisions, heart rate, RMSSD or HF-HRV. In 351 Marines (S11, cluster-randomized), breathing with biofeedback raised respiratory sinus arrhythmia and lowered arousal during multimedia exposure, with PTSD screens as endpoints. In 80 cadets (S15, four arms, four weeks), breathing and mindfulness raised shooting scores and the paper cautions that LF/HF is not a sympathetic index. Boundary: police and military trainees; outcomes are scenario decisions, shot scores and HRV; INTERVENTION throughout; gains appear under psychological threat with task headroom and vanish under metabolic load (S14) and on easy tasks (S13's later shots); breathing was bundled in S5 and S11, so its standalone share is unidentified there.

Slow respiration raises vagal drive on the sinoatrial node and frees processing capacity under anxiety (S30 on efficiency; S12 on resources without lower felt stress); it does not reduce the exertion-driven heart rate of a fight round, and a favourable HRV reading can be produced by the breathing itself, so HRV is not independent evidence that threat regulation improved (S15).

A page may say breathing buys thinking room under fear; it may not say breathing calms the body in a fight, because the one test under physical exertion was null and the positive results came with heart rate unchanged or higher.

Slow breathing buys thinking room under psychological threat when the task has headroom, does nothing against the heart rate of exertion, and a heart-rate-variability change is not proof the alarm was disabled. The adversary refuted its broad form, so the page may carry only the bounded line and should not say breathing calms a body in a fight; 'stay calm and breathe' is bounded, not upheld.

In 57 front-line officers (S6, longitudinal within-subjects), reductions in lethal-force errors and in the extent and duration of autonomic arousal after HRV-biofeedback scenario training were maintained at 12 months and began returning to pre-intervention levels at 18 months; maximum heart rate relative to rest was lowest at 12 months and plateaued at 18. In 27 officers (S1), the protection of shooting accuracy under threat held at a four-month retention test. In healthy adults, cortisol habituation to a repeated stressor was gone ten weeks later (S21). Within the same programme's five-day block (S5 lineage), average heart rate fell and controlled respiration improved across scenarios as they grew more graphic, and lower perceived stress arrived before performance improved. Boundary: police use-of-force trainees; outcomes are lethal-force errors, shot accuracy under threat and arousal; INTERVENTION; the 18-month curve is one cohort of 57 with no untrained comparison across the interval; no combat-sport cohort measured retention of threat-regulated decisions.

Composure is a maintained regulation skill: the error reduction arrives first and the arousal profile reorganises over a year, then both drift back when the exposure that maintained them stops; it behaves like a conditioned capacity with a half-life, not a one-time acquisition (S6, S21).

A page about an interest trained less now may say composure under attack is a maintained capacity that the one long follow-up shows holding a year and fading by a year and a half; it may not say a training block changes a person for good (the skill decay and return vector owns what returns on resumption).

Composure held about a year after scenario training and drifted back by a year and a half in the one long cohort; it is maintained, not acquired once. Single-cohort and refuted as a general horizon, it is carried as the composure half of 'ring rust' and as the time term that the skill decay and return vector's A7 explains mechanistically; for an interest trained less now it is the reason the page writes composure as a capacity kept by exposure.

On the mat, karate experts blocked and counterattacked faster and more accurately than novices and detected a recurring attack pattern after its fifth repetition, which novices never did (S24). Elite officers shot more accurately than rookies (74 percent against 53.8 percent of trials in the opened record, S25) and made very few decision errors in the cell-phone condition, with longer quiet-eye durations on the weapon or where it would appear and more fixations on pre-attack actions of the limbs and hands. Across expert-novice visual search studies in individual and combat sports (S26, meta-analysis), experts used fewer fixations of longer duration on fewer, central body locations. In 35 close-quarters trainees (S32, pre-post, no control), 12 hours of training improved performance and tactical behaviour while gaze behaviour and response time did not significantly change and heart rate and salivary stress fell. In a reality-based training study (S7) both arms improved regardless of added stress, so skill acquisition, not the stress layer, did the measurable work. Boundary: karate experts, police elite-vs-rookie, combat-sport athletes; outcomes are block and counter latency, decision accuracy and fixation metrics; CORRELATIONAL expert-novice contrasts (S24, S25, S26) and INTERVENTION (S32, S7); expert-novice contrasts cannot separate training from selection.

An expert's apparent calm is partly a consequence of earlier, more usable information: anchoring central vision on the trunk lets peripheral vision pick up distal limb motion, and pattern knowledge turns an ambiguous approach into a readable one (S24, S26). A novice made fearless by any means would still be struck, because the information pickup is not there; composure permits the skill to be deployed and does not contain it.

'The entire discipline' fails on this axis alone: reading the strike before it forms is a learned perceptual skill independent of fear regulation (the defense as distance and time vector owns the time budget of one defence). A page may say composure lets a fighter use what training taught the eyes; it may not say composure is the discipline.

Reading pre-attack kinematics is a learned perceptual axis that calm does not supply; experts detect recurring patterns and anchor gaze on the trunk. Refuted by the adversary as a general separability law here, yet the same law stands in the defense as distance and time vector's A3 and the skill decay and return vector's A8 from different evidence, so the page may say composure lets a fighter use what training taught the eyes, never that composure is the discipline.

In 20 amateur boxers and Muay Thai athletes after three three-minute sparring rounds, against 20 controls doing mock sparring (S27), one hour later the sparring group showed greater corticomotor inhibition on transcranial magnetic stimulation, altered motor control and lower cognitive test performance, with values back toward baseline by 24 hours. In 224 professional fighters with 22 controls (S28, cohort), more fights, more years or a higher Fight Exposure Score went with lower thalamic and caudate volume and slower processing speed, processing speed falling 2 to 3 percent per one standard deviation of regional volume lost. In 92 active professional MMA fighters (S29, cross-sectional, conference report), more sparring rounds per week went with greater white-matter hyperintensity volume after adjustment for age, sex, education, fight count and scanner. Pooled pressure-training doses that were long produced the smallest performance effect (S9). Boundary: amateur boxers and Muay Thai athletes (S27, INTERVENTION, acute), professional fighters (S28, S29, CORRELATIONAL); outcomes are corticomotor excitability, cognitive scores, brain volume and white-matter lesions; S29's underlying paper was not opened here. the brain under head impact vector owns the injury physics and thresholds; this axiom carries only the training-variable conflict.

Threat-learning exposure and head-impact exposure are different variables bundled in one activity; the impacts prompt an inhibitory GABAergic response that slows corticospinal transmission for hours (S27) and, cumulatively, cost the processing speed that anxiety forces a performer to overspend (S30, Axiom 1) and that resolving an approach into a read requires (Axiom 2). Hard sparring volume is the weakest pressure-training dose (S9) and the most expensive one (S28), dominated on both axes.

A page may say the practice that teaches a body to stay functional while struck is the same practice that, in volume, slows the mind it is meant to protect; it may not describe hard sparring as the road to composure.

The sparring that habituates a fighter to being hit is a head-impact dose that slows the processing composure is meant to protect, within the hour and across years. Refuted in strong form here and resting on the brain under head impact vector's clamped vector, so it is a lead rather than law; even so, the page's composure lesson may stand only beside a sentence that names this cost, because silence on the brain is the page's largest omission.

For a strike of closing speed u and reduced mass μ = m_s m_t/(m_s + m_t), the target's momentum change is J = (1 + e) μ u and does not depend on the interface stiffness k, while peak force scales as u√(kμ), contact time as π√(μ/k) and peak loading rate as uk; softening the interface (glove, pad, foam, yielding tissue) lowers peak force by the square root of the stiffness ratio and lengthens contact by its inverse while leaving delivered impulse nearly unchanged. Measured on mechanical drop rigs (INTERVENTION, controlled physical measurement), not on people: a 50 mm EVA covering in place of 25 mm lowered peak force and lengthened contact while force-time area stayed within 2.5 percent in 22 of 24 glove and drop-height combinations (S4, 2018); pneumatic gloves cut peak force 25 to 40 percent, cut peak loading rate 47 to 63 percent and lengthened contact more than 50 percent, with peak-force change tracking contact time at R² above 0.96 (S5, 2018); 26 to 34 percent of a 253-drop upward drift in peak force came from the mat ageing, not the impactor (S6); mat thickness and compaction changed net force by multiples under an 8 kg weight dropped from 15 to 50 cm (S21, 2024). Boundary: the restitution and series compliance of glove, skin and neck for a fist on a head were not separately measured in any opened source; the algebra is assumed to transfer.

A compliant contact is a mass on a spring for the duration of the collision (S26, S27). Momentum conservation fixes the impulse from μ, u and e alone; the spring only sets how that impulse is spread in time. Putting the measured 25 to 40 percent peak reduction into the half-sine model gives a stiffness ratio r of 0.36 to 0.56, predicting a loading-rate reduction of 44 to 64 percent and contact lengthening of 34 to 67 percent; the rig measured 47 to 63 percent and more than 50 percent (S5), three independently measured ratios with no free parameter.

On the michaelquoc.com page any sentence that ranks a strike by its force names a property of the thing hit, not the striker; a sentence about how hard a punch or kick lands is sound only with the target named. The page as written quotes no force figure.

Peak force is a property of the collision's stiffness; impulse is what the target keeps, so a glove or pad lowers the peak and lengthens the contact while the momentum delivered barely moves. The vector was clamped for misquoted sources, so this is a derivation the page may describe and not a number it may quote; it is why any 'how hard' sentence must say what was hit.

In striking studies 'effective mass' names three estimands: peak force over fist acceleration on a rigid plate, impulse over incoming hand speed on a padded plate, and the inertial mass back-computed from a surrogate head's momentum change. For straight punches they read 30.39 to 31.17 kg in 30 trained boxers (S10, 2025) or 18.50 to 18.95 kg, about 21 percent of body mass, in elite boxers (S11, 2024); 2.60 kg in 50 untrained adults (S1, 2021); and 2.9 ± 2.0 kg in Olympic boxers striking a Hybrid III head (S7, 2005). The gap is mechanical, not a training difference: the target receives (1 + e) μ u, and against a head of a few kilograms the reduced mass μ cannot exceed the head's own mass however much body is coupled behind the fist, while against a wall-mounted plate μ tends to the striker's coupled inertia (S26, S27). The force-over-acceleration definition is in addition algebraically anti-correlated with acceleration, so the findings that effective mass falls as fist acceleration rises and that hooks read lower effective mass than straights despite higher peak force (S10, S14), and that a side kick reads 73.09 percent of body mass against 20.12 percent for a turning kick on a twofold acceleration denominator (S23, 2024), are partly definitional. Populations: trained, elite and Olympic boxers, untrained adults, Taekwon-Do practitioners; outcome: effective mass by each definition; class: CORRELATIONAL cross-sections and within-person descriptives, the MODEL supplying the reconciliation. No study measured all three definitions on one punch.

The contact-point inertia in direction n is [nᵀ A M⁻¹ Aᵀ n]⁻¹, a property of configuration, segment inertias, joint coupling over the collision timescale and support constraints (S26); it is neither fist mass nor body mass. Coupled inertia and endpoint speed trade against each other because stiffening a joint to recruit proximal mass also loads the distal segment during acceleration, so the optimised quantity is the product m_e v and the optimal split depends on target mass (S14). Reactive stiffening cannot act inside a 5 to 15 ms contact, so only pre-set activation and skeletal alignment raise coupled inertia, consistent with training tenure correlating with effective mass (S14); this is an inference from timing, not a measured latency.

A page sentence that says a fighter puts his body weight behind a strike is testable only as a coupled-inertia claim against a named target; no number for it transfers between a plate, a bag and a head.

'Effective mass' names three different estimands that disagree by up to an order of magnitude for the same punch, and a head of a few kilograms caps what any punch can give it however much body is coupled behind the fist. A derivation worth keeping as a lead; it voids any page sentence about 'body weight behind' a strike that names no target.

Fist or foot speed peaks before contact and falls by the time the strike lands: in 16 elite and junior boxers mean peak fist speed was 7.16 m/s against a contact speed of 5.56 m/s (elite) and 6.32 against 4.87 m/s (junior) (S2, 2022); in 24 skilled Muay Thai, Karate and Taekwondo practitioners foot speed at contact was 41 to 54 percent of its earlier maximum (S3, 2017). Speed at contact is the striker-side quantity that covaries with delivered load on one rig: foot velocity at impact against relative impact force r = 0.66 in those 24 practitioners (S3); pre-impact hand velocity explained 39 and 38 percent of punch-force variance in 42 amateur boxers against 10 percent for leg forces (S12, second-hand through a 2013 review); elite boxers' higher contact speed came with about 1,508 N against 1,035 N for juniors on one target (S2). Populations: trained boxers and kickers; outcome: contact velocity and impact force within one rig; class: CORRELATIONAL. Bound: speed enters impulse linearly and deformation energy as its square, ½ μ (1 − e²) u², so against a light target that caps μ, speed is the one striker lever that never saturates (S27).

Contact velocity is the vector sum of shoulder or hip translation and each segment's absolute angular velocity crossed with its lever arm; segments can reinforce or oppose one another, so fast trunk rotation does not guarantee a large component into the target, and the pre-contact deceleration in S2 and S3 is the chain decoupling or the striker braking before the pad (S26). Peak speed measured anywhere on the limb is not the collision input; the contact point's velocity in the contact normal at first contact is.

A page sentence about a fighter's speed is the one striker attribute that transfers across targets; a sentence about power does not. Neither sentence bears on composure or panic, which this vector does not test.

Only the contact point's speed at first contact enters the collision, well below the limb's peak, and it is the striker lever that tracks delivered force without saturating against a light target. Flagged for a number not found on its source page; the direction, that speed transfers across targets and 'power' does not, is sound and awaits a clean pass.

A striker's whole-body linear momentum changes only through the friction impulse at the feet, capped by μ_s N Δt, and whole-body angular momentum only through the moment of the ground-reaction pair about the centre of mass; joint torques redistribute momentum between segments but cannot create it, and an ideal planted foot does no mechanical work (P = R · v_foot = 0), so muscle work funds the limb's kinetic energy (S26, S27; MODEL). The measured chain shows the redistribution: in 16 boxers trunk angular velocity rose as lead-leg ground force rose and rear-leg ground force fell, peaking at impact, the lead leg acting as the pivot (S2, 2022). How much punch force the legs explain depends on sample and rig: rear- and lead-leg peak-force models accounted for roughly half of cross peak-force variance in 12 elite amateur boxers on a suspended chin-height plate at 12,000 Hz (S13, as read from the abstract), but leg forces explained 10 percent against 39 and 38 percent for hand velocity in 42 amateur boxers (S12, second-hand); the widely quoted 38.46 / 37.42 / 24.12 percent leg, trunk and arm split is a 1985 dynamometer result no leg opened (S12). Rear-leg drive associated with the cross as the largest pre-fatigue output and with its resilience to fatigue (S29, 2025). Populations: elite and amateur boxers; outcome: ground-reaction variables against punch force; class: CORRELATIONAL regressions plus the MODEL.

The articulated equation M(q) q̈ + h = τ + A_gᵀ R − A_cᵀ F keeps ground reaction, joint torque and contact force as separate terms; nothing travels up the chain unchanged (S26). A large vertical foot-force peak does not by itself set horizontal fist momentum because direction, point of application and duration of the ground reaction all enter the impulse. Proximal-to-distal sequencing maximises endpoint speed by progressively decoupling distal segments from proximal inertia, the same lever that lowers coupled inertia at contact.

A page sentence that credits a kick's or punch's force to the hips or legs as a share is not supportable with one number; a sentence that says the legs drive the body and the trunk rotates into contact is.

The ground supplies external impulse and the couple but does no work at a planted foot; joint work funds the strike and the chain redistributes it, so the quoted 'leg contribution' percentages are rig-dependent regression coefficients, not a share. Clamped on a source tripwire; the page may say the legs drive the body and the trunk rotates into contact, never a percentage.

Reported peak punch force across 23 studies spans 989 ± 117 to 5,008.6 ± 76.3 N, a fivefold range dominated by target stiffness, mounting, padding, sampling rate and event definition rather than by who punched (S17, 2025 review); on one wall-mounted dynamometer the ladder 4,800 ± 227 (elite), 3,722 ± 133 (intermediate) and 2,381 ± 116 N (novice) is a valid rank order on that plate and nothing more in absolute terms (S17, second-hand from Smith et al. 2000); within one rig repeatability can be high (ICC 0.995 to 0.999, typical error at or under 5 percent on an instrumented water bag, S24, 2022) yet for absolute peak impact force the standard error of measurement most often exceeded the smallest worthwhile change (S25, 2023); commercial wrist and glove trackers correlated 0.23 to 0.43 with criterion peak force in 10 trained and 10 untrained punchers (S20, 2023); and the rig itself drifts, 26 to 34 percent of a 253-drop rise in peak force coming from the mat (S6). Populations: boxers across levels, trained and untrained punchers, drop rigs; outcome: peak force and its reliability; class: CORRELATIONAL device studies and reviews, INTERVENTION drop tests.

A plate behind padding records F_plate = F_contact − dP_pad/dt, so surface and plate peaks differ while their impulses agree if the pad returns to rest; an accelerometer on a rotating segment reads a_G + α × r + ω × (ω × r), not contact force, and recovering force needs a dynamical model, not an assumed mass (S26); a bag's swing is a global momentum response that hides the local pressure field. A defensible impact record needs synchronized contact force and contact-point motion, a known target constraint, characterized compliance, adequate bandwidth and a defined integration window; absent those the number is the rig's.

Any Newton figure the page might quote for a punch or a kick is honest only with the rig named beside it; a figure quoted alone is no number. The page as written quotes no force figure.

A force number compares only within one rig with a stable interface; across rigs only impulse, momentum and limb kinematics transfer. This is the estimand law of the threat response under strikes vector's A4 and the brain under head impact vector's A2 applied to force; its sources were clamped with the vector, but the rule itself is the reason the page quotes no newton figure and the reason 'bag force predicts injury' is refuted.

Olympic boxers' straight punches to a Hybrid III frangible face produced punch force 3,427 ± 811 N at hand velocity 9.14 ± 2.06 m/s with effective punch mass 2.9 ± 2.0 kg, jaw load 876 ± 288 N, head translational acceleration 58 ± 13 g, rotational acceleration 6,343 ± 1,789 rad/s² and neck shear 994 ± 318 N (S7, 2005); professional boxers' hooks produced the largest hand-velocity change (11.0 ± 3.4 m/s), punch force 4,405 ± 2,318 N, 71.2 ± 32.2 g and 9,306 ± 4,485 rad/s² (S8, 2005). The nonzero neck shear shows the head is not a free body over the contact, so the free-collision Δv is an upper bound on head velocity change; rotational acceleration is α ≈ F d / I_head, a lever-arm quantity, so the contact's position relative to the head's centre changes angular loading by factors at constant force. The compiled finding that a roundhouse kick loads the head harder than a hook (130.11 ± 51.67 g vs 71.23 ± 32.19 g; HIC15 162.63 clench axe kick vs 24.10 uppercut) is cross-rig, a helmeted Hybrid II against a bare Hybrid III with different necks and mountings, and gives a direction consistent with the kick's higher contact speed and larger segmental inertia, not a ratio (S9, 2013). Populations: Olympic and professional boxers striking surrogate heads, taekwondo athletes on a different surrogate; outcome: head linear and rotational acceleration, jaw load, neck shear; class: INTERVENTION (controlled physical measurement on surrogates), the kick comparison CORRELATIONAL across studies. The axiom ends at loading; the brain's response belongs to the brain under head impact vector.

Head momentum change is the contact impulse plus the neck impulse; head angular momentum change is the contact impulse's moment about the centre of mass plus the neck moment (S26). A freely moving head's inverse normal effective inertia at an off-centre contact is 1/m_head + (r_c × n)ᵀ I⁻¹ (r_c × n), so rotation gives the contact point extra freedom to move, and the neck removes some of it. Translational acceleration loads the skull in compression; angular acceleration shears the brain within it, and a single accelerometer at the head's centre records only the first (S9). Contact durations in finite-element head models ran 0.17 to 3.29 ms (S22). The headform inertia behind the ~5 cm lever-arm estimate was not opened by any leg; that estimate is order-of-magnitude only.

A page sentence about strikes coming at the head can honestly say a boxer's punch moves a head at tens of g and thousands of rad/s² and that the point of contact sets the rotational share; it cannot rank punch against kick by a number from these sources.

A boxer's punch moves a surrogate head at tens of g and thousands of radians per second squared, the rotational share set by the contact's lever arm about the head's centre and bled by the neck; the kick-versus-punch head comparison is cross-rig and gives a direction, not a ratio. Clamped with the vector; it hands the brain under head impact vector the loading that the brain under head impact vector's A5 says has no single injury threshold.

In blunt chest and abdomen impacts on biological surrogates, injury tracked the viscous response VC, the maximum of deformation velocity times compression, with VC = 1.0 m/s the serious-injury level frontally and maximum compression 32 to 40 percent at the same risk (S18, 1988), and VC 1.47 m/s (chest) and 1.98 m/s (abdomen) at 25 percent probability of critical injury laterally with compressions of 38 and 44 percent (S19); a compression survivable at low speed is fatal at high deformation velocity because the viscoelastic body's resisting force rises with loading speed (S18). So the torso is loaded by penetration depth times penetration rate, the head by impulse and moment arm, and a bone or skin surface by stress F/A, where the same total force over a smaller or stiffer contact raises local stress (S1's caution on contact area and impactor rigidity). A fast, low-coupled-mass whip maximises VC; a slower, high-coupled-mass drive maximises head Δv against a braced target; a knuckle or shin edge maximises F/A. Populations: cadaveric and animal surrogates in automotive impact testing, 1988 to 1989; outcome: VC and compression at injury; class: INTERVENTION (controlled impact). Only one leg opened these sources, so SIGNAL is the honest claim even though the viscous criterion is standard injury biomechanics.

Normal force is pressure integrated over the contact area, so F/A is only the average pressure; local stress needs geometry, tissue thickness, support and a rate-dependent constitutive law (S1, S26). Energy entering the target is the integral of F over indentation, not F_max (S27), and the lost translational energy ½ μ (1 − e²) u² partitions into deformation, damping, heat and vibration; the viscous criterion is the empirical finding that for soft organs the rate of deformation, not its depth alone, fails tissue.

If the page ever compares a body kick with a head kick or a punch, the honest frame is that they load different things by different laws; no single hardest strike exists across targets. The page as written makes no such comparison.

Torso, head and surface are loaded by three different variables (deformation velocity times compression, impulse and moment arm, force per area), so no single hardest strike exists across targets. Single-leg and clamped; a frame the page may use if it ever compares a body kick with a head kick, not a claim it may state as measured.

On one restrained strain-gauge pad, 24 skilled practitioners' roundhouse kicks read 1,547 ± 530 N (Taekwondo), 1,400 ± 419 N (Muay Thai) and 1,211 ± 219 N (Karate) with no significant between-discipline difference, and impulses of 38.8 ± 15.3, 38.1 ± 12.3 and 30.9 ± 6.9 N·s (S3, 2017), about 1.6 to 2.0 times the 19.57 N·s a dominant-fist punch delivered on a padded plate in 50 untrained adults (S1, 2021), on different rigs, so a direction and not a ratio. On a stiffer instrumented dummy the same technique reads 1,994 ± 537 N in experts against 1,477 ± 679 N in novices, maximum 3,482 N (S16, 2009); across rigs the review range for a roundhouse is 1,720 to 6,400 N with foot velocities up to 18.3 m/s (S28, 2024). Expertise shows in how force holds, not in its size: experts' impact force did not change with execution distance while novices' fell at the long distance and tracked body mass (S15, 2013; S16), all competitors having four or more years. The effective mass of a kick read as force over foot acceleration is the same definitional artefact as in punches: 73.09 percent of body mass for a side kick against 20.12 percent for a turning kick on a twofold acceleration denominator (S23, 2024). Populations: skilled Muay Thai, Karate and Taekwondo practitioners, expert and novice taekwondo competitors, Taekwon-Do practitioners; outcome: pad impact force and impulse by distance and level; class: CORRELATIONAL cross-sections. The S3 protocol allowed foot-to-shin contact and foot-marker velocity is not shin-contact velocity, so S3's numbers cannot be divided into a shin effective mass.

The leg's segmental inertia is a multiple of the arm's and the shin's contact point moves faster than a fist, so both factors of (1 + e) μ u are larger against a heavy restrained pad (S27). For a rigid rotor, v_c = rω and m_eff = I/r² at the contact radius: moving contact farther from the pivot raises its speed at fixed ω and lowers its effective mass at fixed I, so the shin-versus-instep choice trades speed against coupled inertia and creates no energy (S26). Expert distance-insensitivity is the chain absorbing the spatial degree of freedom in timing rather than in delivered momentum; the novice body-mass correlation is bulk standing in for coordination.

A page sentence that calls Muay Thai kicks harder than another art's kicks has no measured support (S3); a sentence that says a trained kicker's force holds across distances where a novice's does not has it (S15, S16).

On one pad the roundhouse delivers more impulse than a punch through larger segmental inertia and faster shin contact, no art's kick measured harder than another's, and expertise showed as force that holds across distance where a novice's falls off and tracks body mass. Clamped with the vector; the one line the page may carry as a lead is the expert distance law, and 'Muay Thai kicks hit harder' has no measured support.

A newly selected defensive movement protects the head only if the strike's arrival time, counted from the earliest usable cue, is at least the defender's cue-to-initiation latency plus the movement time needed to reach a protective state (T_A − t_C ≥ L + M). The strike's duration is not a property of the punch: in experienced boxers on a bag the fist's throw phase is about 111 to 117 ms (jab 117 ± 25, cross 111 ± 41 ms; Menzel & Potthast 2021, instrumented glove), the same punch counted from first detectable body motion to contact runs 357 ± 178 ms for straights and 477 ± 203 ms for hooks (Piorkowski 2011, amateur boxers, motion capture), and counted from a start signal 2 to 2.5 m away runs 512 ms for head punches and 610 to 664 ms for kicks (Rosalie & Müller 2013, karate, in situ). The ratio between the earliest and latest defensible start markers for one strike is about 3 to 4, and that ratio is the whole territory a defender's reading can win. Boundary: experienced and amateur boxers and karateka on bags, pads or scripted live attacks; no opened study jointly measured cue extraction, decision latency and geometric clearance in one unrestricted exchange; the inequality is a derived feasibility condition (MODEL), the durations are controlled physical measurements.

Fist peak velocity of 6.6 to 12.5 m/s is reached only 8 to 21 ms before contact (Whiting 1988, four experienced boxers), so the most visible part of the strike sits far inside any visual response latency; usable time exists only in the body motion upstream of the fist in the kinetic chain, which is also upstream in time. Observation: the durations. Inference: the 3 to 4 ratio compares markers across populations and tasks.

Any page sentence quoting 'a punch takes X ms' must name the start marker and setup or it says nothing; the honest statement is a range from about 110 ms (fist flight) to about 500 ms (from first body motion at range).

A defense is a margin on one clock, and a strike's measured duration depends on where the clock starts, from the fist's flight to first body motion at range. Clamped with the vector for misquoted sources; the inequality is the frame the page needs for any sentence about reflexes, and it is the same estimand law the threat response under strikes vector's A4 and the brain under head impact vector's A2 state for other quantities.

A visually triggered defensive movement cannot begin in less than roughly 150 to 180 ms of neural processing plus about 26 to 41 ms of electromechanical delay (biceps 41 ± 13 ms, triceps 26 ± 11 ms in concentric contraction, not influenced by movement velocity; Norman & Komi 1979), so sub-100 ms responses in combat-sport protocols are discarded as anticipations by convention. Expertise compresses the neural term by only about 25 to 40 ms (athletes vs non-athletes: visuomotor reaction 243 vs 274 ms and 234.9 vs 260.3 ms, EMG onset 178 vs 217 ms; Hülsdünker cohorts, between-group). In an in-situ karate kumite decomposition, moving from one alternative to four alternatives plus an auditory distractor raised reaction time from 235.0 ± 35.0 to 351.1 ± 59.1 ms (+116 ms) while motor response time moved from 122.7 ± 27.7 to 131.7 ± 35.8 ms (+9 ms): uncertainty costs decision time almost entirely and movement time almost not at all. Generic choice RT did not predict level among 123 karate competitors including 11 world champions (Martínez de Quel 2015), and karate athletes showed faster choice responses to attack video but no simple-RT advantage (Mori 2002). Boundary: laboratory and in-situ scripted tasks on karateka, badminton players and healthy adults; the simple-vs-choice split is a within-person manipulation, the expert gaps are correlational, the electromechanical delay is a controlled physiological measurement.

Motion-onset visual evoked potentials sit near 170 ms after stimulus onset and premotor activation near 150 ms; these are conduction and integration times with narrow trainable range. Electromechanical delay is tendon slack and calcium kinetics, untrainable. Choice reaction time grows with the number of alternatives (the Hick-Hyman relation, a log fit that degrades past about 3 bits). Inference: the decision term is the only latency lever training can reach.

A page may say a defender under genuine uncertainty needs about 350 ms to start moving and about 235 ms when the strike is known; it may not say training makes reactions fast, because the trainable part is tens of milliseconds against a fist flight of about 110 ms.

The visual response floor is nerve and tendon that training barely moves; uncertainty is taxed in decision time, not movement time. Clamped; carried as the lead that forbids 'training makes reactions fast' and as the mechanism the pressure against precision vector's A3 uses when it says pressure forces errors through the clock.

In an in-situ temporal occlusion study of live karate attacks (Rosalie & Müller 2013; experts, near-experts and novices; attacker starting 2 to 2.5 m away; vision removed at a static stance, after preparatory head movement, or after attack initiation), only experts blocked above chance from the static on-guard stance; near-experts exceeded chance only at the two later points; novices only with the attack in motion. Against a strike whose action-to-contact time is 357 to 477 ms, the expert's gain is hundreds of milliseconds of earlier clock start, while the expert's gain in raw latency is tens of milliseconds (meta-analytic reaction-time SMDs fencing −1.07, karate −1.23, judo −0.54 are a secondary term). In live kumite (Petri, Droste & Witte 2020), recognition of arm attacks was most often inferred at early steps and reduction of interpersonal distance, an inferred interval, not a timestamped event. Expert gaze follows the kinetic chain: experienced boxers fixate head and trunk with fewer, longer fixations along the midline while novices chase fists and arms (Ripoll 1995 via review; 2021 boxer eye-tracking pilot); 11 elite boxers kept dodge and counter performance under gaze-contingent blur (Limballe 2024). Boundary: occlusion fixes what information sufficed by a cutoff, not when recognition occurred; static-stance information is probabilistic and its source unresolved; karateka, French and amateur boxers; correlational expert-novice contrasts with within-person occlusion.

Force is produced proximally before it is expressed distally: weight transfer, pelvic rotation and trunk motion precede fist departure because the kinetic chain runs legs to trunk to arm, so the earliest information is in the trunk, not the fist. Gaze anchored centrally lets motion-sensitive peripheral vision pick up the limbs without saccade cost. Observation: the occlusion and gaze results. Inference: the proximal-to-distal explanation of why those cues exist.

The page may say the skilled defender's edge is reading the body before the strike, not faster reflexes; it may not quantify that edge beyond 'hundreds of milliseconds against tens' without naming Rosalie & Müller's task.

Expertise moves the start of the clock, reading stance and preparation above chance before the attack is moving, rather than speeding the clock. Clamped, but the same law stands in the training composure vector's A7 and the skill decay and return vector's A8 from different evidence; the page may say the skilled defender's edge is reading the body before the strike, not faster reflexes.

Define the horizon t_h = T_contact − T_D (the defender's total loop); any cue emitted after t_h is processed only after the fist has landed. Peak fist velocity of 6.6 to 12.5 m/s occurs 8 to 21 ms before contact in four experienced boxers (Whiting 1988), about twenty times inside a 350 to 480 ms loop, so the fist is the one segment whose motion is informative only when it is already arriving. Readability is a property of the pre-horizon interval: in a four-alternative video occlusion task with ten expert boxers (Limballe 2026, motion-capture animations), anticipation accuracy (the share of correct punch-type calls across trials) fell as occlusion moved earlier and straights were read far better than hooks (lead straight 0.744, rear straight 0.660, rear hook 0.455, lead hook 0.435). A karate punch's whole kinematic and EMG sequence sits within about 400 ms with arm activity before forearm extension (VencesBrito 2011, 18 team karateka vs 19 novices), and elite amateur boxers partially flex the elbow at punch onset, a tell the authors call intent advertisement (Cheraghi 2014, eight boxers). Boundary: experienced and elite amateur boxers and team karateka; correlational expert-novice and punch-type contrasts; controlled kinematics; the 2026 accuracies come from animations, not a live opponent; the 'twenty times' ratio divides intervals from different populations and is a scale illustration.

The kinetic chain runs legs to trunk to arm, so pre-horizon information exists in trunk and shoulder while distal segments peak last. A curved trajectory shares its early posture with other strikes longer than a straight does, so its branch point comes later and the pre-horizon interval carries fewer bits. Observation: velocity timing, accuracies, the sequence. Inference: the horizon definition and the branch-point account of straights versus hooks.

The page may say the punch you can see is the punch you cannot defend and that hooks are harder to read than straights; it may not give a readability number without naming the ten-boxer four-choice animation task.

Information a strike emits after contact time minus the defender's loop is inert, so the fist itself is undefendable and curved strikes branch later than straight ones. Clamped; a derivation the page may describe (the punch you can see is the punch you cannot defend) without quoting a readability number.

Remaining time is the integral of distance over closing speed, and for an otherwise unchanged strike the time added by extra range is about ΔD divided by closing speed: at 8 m/s, inside Whiting's measured contact-velocity band of 5.9 to 8.2 m/s, 10 cm buys about 12.5 ms (a constant-speed local approximation, MODEL). The large gain comes from another mechanism: out of reach the attacker must move first, and locomotion is a whole-body, large-amplitude, early cue. Atha's cross as reported by Piorkowski (2011) is about 100 ms of punch preceded by about 200 ms of advance; Rosalie & Müller's attacks from 2 to 2.5 m took 512 ms (head punch) to 664 ms (kick) from signal to nominal contact against an in-reach fist flight near 110 to 117 ms (Menzel & Potthast 2021). In live karate both distance and attacking technique significantly affected the defender's reaction (2016 in-situ study). Added range also shrinks the optical size of a lateral body movement roughly as 1/R, so distance improves the deadline without guaranteeing equally readable evidence. Boundary: the per-centimetre number is a straight-path constant-speed model; a lunge changes path length and target together; experienced boxers on a bag and karateka in scripted live attacks; the optical cost is an inference with no opened measurement.

Time to contact is path length over speed along the actual path including the attacker's body translation; stepping forward adds a slow, high-mass phase before the fast, low-mass fist phase, and that approach phase is the one part of a strike that is both early and large. Observation: durations at range and the karate distance effect. Inference: the per-centimetre figure and the 1/R optics.

A page may say distance is the defender's largest reservoir of time and is spent the instant the striker is in reach; it may not say a step back makes you safe, because the step adds centimetres (milliseconds) unless it puts the attacker out of reach (hundreds of milliseconds).

Inside reach each centimetre buys about a millisecond; out of reach the attacker must step first, and that slow early step supplies the real reservoir of time. Clamped; it is the time half of the pressure against precision vector's A1 on pressure closing space, and it is why 'a step back makes you safe' is false unless the step puts the attacker out of reach.

Two operations must be separated (Panten et al.): disguise withholds cues and raises the number of live alternatives, costing the Hick term, which in the karate kumite decomposition is about +116 ms of decision time from one alternative to four plus a distractor; deception supplies misleading cues and installs a wrong prediction. In point-light soccer (PLOS ONE 2014, within-person video task) responses were faster when the cue matched the feint rather than the true direction, in displays reduced to dots with the head as two points, so the effect does not depend on gaze: the observer is not slowed, he is loaded in the wrong direction and must re-select and reverse a movement under way, with braking time at least u/a and extra distance at least u²/2a. Observer cost of a basketball head fake: 422 vs 492 ms and 501 vs 553 ms, about +50 to +70 ms plus more errors (laboratory choice tasks, healthy adults). The cost is base-rate priced: at 20 percent fake frequency 332 vs 349 ms, at 50 percent 340 vs 338 ms, nothing (within-person frequency manipulation). A feint can donate warning: in eye-tracked VR boxing with scripted sequences, first-punch interception probability was 0.353 after a foot feint, 0.197 after an arm feint and 0.252 with no feint, because every feint in that task preceded an attack (Limballe 2022). Boundary: magnitudes from basketball and soccer laboratory tasks on healthy adults and one VR boxing study; no opened study measured a feint's millisecond cost in live striking; the frequency result rests on one group's paradigm; within-person interventions and correlational designs; the braking bound is MODEL.

A feint exploits a learned prior and consumes it as fuel; a feint thrown half the time conveys zero bits. A deceptive cue moves the mode of the defender's prediction to a false location, so the price is selection plus the mechanical reversal of displacement and momentum. Observation: the millisecond costs, the frequency effect, the VR probabilities. Inference: the bias-versus-variance framing and the braking algebra.

The page may say a feint buys tens of milliseconds and extra errors by making the defender commit early and that a feint thrown too often buys nothing; it may not say a feint freezes a defender for hundreds of milliseconds, because the opened measurements are 50 to 70 ms.

A feint spends the defender's commitment by exploiting a learned prior, costs tens of milliseconds and extra errors, and buys nothing when thrown half the time. Tripwired on a misquoted source; the folk line 'everyone has a plan until they get punched in the mouth' gets its bounded form here as a lead, and 'a feint freezes a defender' is not supported.

Producing a fake is slower than the true action: initiation 444 ms with a head fake vs 432 ms without, and in an ex-Gaussian re-analysis fake-production costs of 52.0 ms (effort instruction) and 39.7 ms (standard) at zero preparation, collapsing toward zero at 500 to 1000 ms of preparation; practice did not remove the zero-preparation cost (laboratory basketball-pass tasks, healthy adults, within-person). So an improvised feint buys the defender's 50 to 70 ms and pays 40 to 50 ms of its own initiation, near a wash, while a prepared feint pays nothing in initiation but spends at least half a second of preparation inside the defender's most valuable pre-horizon window. Skilled athletes read early kinematics better yet remain susceptible to deception, in some studies more than the less skilled: experienced players anticipated deceptive actions better but were still impaired and anticipated non-deceptive actions less accurately than novices; exaggerated movement shifts perceivers to a cue-based mode with overconfidence (soccer penalty kicks). In badminton, emphasising kinematic (low spatial frequency) information preserved skilled players' accuracy against deceptive shots while non-kinematic emphasis reduced it (Park et al., 12 vs 12). Boundary: producer costs are from basketball-pass laboratory tasks, not strikers; expert-vulnerability findings are from soccer and badminton video tasks; no opened combat-sport study measured a striker's own feint cost; within-person interventions and correlational contrasts; the ledger is MODEL.

Response-response incompatibility in selection: planning a false and a true action together costs selection time unless preparation separates them. Anticipation and deception vulnerability are one mechanism read from two ends: the early pickup that gives the expert hundreds of milliseconds is the surface a feint writes on. Observation: production costs and expert impairments. Inference: the initiation-versus-legibility ledger.

A page may say deception is never free for the striker and that reading skill and feint vulnerability are the same faculty; it may not say experts see through feints.

The striker pays for a feint out of his own initiation time or his visible preparation, and the defender best at reading early cues is the one most exposed to deception. Tripwired; a lead that says deception is never free and that reading skill and feint vulnerability are one faculty.

Feasibility is that the defender's reachable set intersects a geometrically safe region before contact, not that a technique finishes: the glove volume and the exposed head volume must never intersect through the dangerous part of the path, and from rest the minimum movement time for a clearance δ at useful acceleration a is √(2δ/a), 100 ms for 10 cm at 20 m/s² (MODEL). The fist travels about 0.65 m in about 0.3 s (Cheraghi 2014) while a head needs only glove radius plus half a head width, about 0.13 to 0.15 m (anthropometric model, no source opened), so a 4 to 5 to 1 advantage in required distance roughly cancels a 6 to 1 deficit in speed; large defenses fail categorically where a part-complete slip may still clear. A guard already in position costs no perception, decision, electromechanical delay or movement time; its price is geometric, a fixed prior over angles a striker re-aims around. International boxers reached peak force in standardized defensive movements in 85 ± 18 ms vs 112 ± 21 ms at national level, but time to peak force is not time to leave the collision corridor (Wang & Korobeynikov 2026). The margin is a distribution: pooling the straight-punch SD of 178 ms (Piorkowski) with the defender's SDs (35 and 28 ms, Petri) gives σ ≈ 184 ms on a mean margin near zero in the favourable cell, and MMA fighters after a Wingate test lengthened reaction time 1.5 percent while its consistency worsened 14.7 percent (within-person pre-post), so fatigue widens the tail rather than shifting the mean. Boundary: the clearance distance is unmeasured; the σ figure pools SDs across studies and punch modalities (the 178 ms SD pools modes and inflates spread); the fatigue datum is one MMA cohort; amateur and international boxers, MMA fighters; MODEL for sufficiency and variance, controlled measurement for the kinematics.

Collision avoidance is a volumes-and-trajectories problem, so partial credit exists for displacement and none for a technique's completeness; position substitutes geometry for time. A near-zero mean margin with a wide spread makes success a coin flip whose odds move with variance. Observation: the Cheraghi displacement, the Wang peak-force times, the MMA fatigue percentages. Inference: the clearance anthropometry, the σ arithmetic, the sufficiency law.

The page may say the small, early, partial movement and the pre-set guard are what fit inside the time budget and that fatigue costs consistency before speed; it may not quote a clearance distance or a success probability.

A defense completes to sufficiency, not completion: small early displacements and a pre-set guard fit the budget, and fatigue widens the margin's spread before it shifts its mean. Tripwired; the fatigue-variance datum is the same one the pressure against precision vector's A3 carries at higher weight, and the sufficiency law is why evasion is possible at all against a faster fist.

Define the defender's exit set as every trajectory or defensive action that can be completed before the attacker's earliest interception, bounded by boundary geometry, by the defender's momentum and support leg, and by the time margin between the attacker's arrival and the defender's clearance. Pressure shrinks that set spatially and temporally; placement prunes it posturally by punishing one chosen response until the defender stops choosing it. The one opened intervention on geometry: in 20 male regional and national kickboxers performing nine randomized 2-minute combats, shrinking the area from 6 m x 6 m or 4 m x 4 m to 2 m x 2 m raised block-and-parry counts (d 0.47 and 0.66) and backwards-lean actions and lowered foot defenses (d 1.04 and 0.63) (S3, INTERVENTION, within-person). In 108 international elite amateur boxing bouts ring-centre control stayed independently associated with winning after adjustment (OR 1.07, conditional logistic model, S2, CORRELATIONAL). Being backed up is not being controlled: blocking, checking, clinching and countering stay open when escape closes, and the 2 m x 2 m condition shows exactly that reallocation. Boundary: the area study is sparring in kickboxers, not a professional bout; the exit-set model is a MODEL, not a fitted index; no validated pressure score exists.

A body cannot occupy every exit before one deadline; movement from rest covers a distance proportional to the square of the time left after reaction, so halving the time left quarters the reachable distance, and a step that covers the defender's likely path removes an exit without a strike. A smaller enclosure reallocates defense from the feet to the arms and torso because foot escapes need distance and time that the enclosure no longer supplies.

The page may keep a mechanism sentence, but only this one: pressure and precision are two ways of removing an opponent's options, one by closing space and time, the other by punishing the option the opponent keeps choosing; they are not opposite styles.

Pressure and placement are two operators on one quantity, the defender's set of exits still executable before interception; the one experiment on fighting area shows a smaller space reallocates defense from the feet to the arms. The adversary refuted the strong form while the gate verified its sources; it is the mechanism sentence the page may keep in place of its two-opposed-styles contrast, with the defense as distance and time vector's A5 as its time half.

In 26 elite male amateur boxers at a national championship, winners landed 33 percent of punches against losers' 23 percent and threw 17 percent air punches against 27 percent, while total punches, defensive actions and interaction time were similar (S1, CORRELATIONAL, 2017). In 108 international elite amateur bouts from 2019 to 2025 (216 boxer observations, matched winner-loser pairs), punching accuracy (OR 1.26), defensive success rate (OR 1.18) and ring-centre control (OR 1.07) were each independently associated with winning after adjustment, total punches thrown adding only OR 1.06 per unit (S2, CORRELATIONAL, 2026). On the professional record, Rodtang stormed back and tagged Takeru at will in rounds three and four of their April 2026 kickboxing bout and was dropped four times and stopped at 2:22 of round five (S15, S16, bout record). Population: elite amateur boxers for the measurements, two professional strikers for the case. Boundary: the odds ratios are per-unit and model-dependent; no Muay Thai dataset with a position variable was opened; the case is one bout.

Volume is a cost line, paid in energy and exposure; it becomes revenue only when it lands on a target or removes an exit. Accuracy and position are the variables that convert work into scoring events, so two fighters with equal counts can sit on opposite sides of the result.

Any sentence on the page that equates forward pressure with high output, or precision with low output, must go; the honest sentence is that output is what a fighter spends and accuracy and position are what he buys.

Output, accuracy and constraint are three quantities: winners and losers threw similar volume and differed on accuracy, defensive success and ring-centre control, and a fighter won the volume rounds and lost the bout. It survived the adversary with every source confirmed and is the run's firmest result; it removes 'pressure equals output' from the page and refutes 'the best defense is a good offense' as a volume claim.

In 20 national first-class boxers and 20 novices, occluding an attack-or-defense video at 80 ms before action onset lowered recognition accuracy and reaction time relative to 40 ms before and to action start, and mental fatigue from a 45-minute Stroop task lengthened reaction time without changing accuracy (S5, INTERVENTION, mixed design). In 47 Polish K-1 national team kickboxers, having to decide whether to start or change an action in reaction to a stimulus significantly (p < 0.001) extended total task time, and the time spent deciding did not differ by which action was chosen (S6, INTERVENTION, within-person). In 45 MMA fighters an upper-body Wingate test lengthened simple visual reaction time by 1.5 percent and worsened its consistency by 14.7 percent (S4, INTERVENTION, within-person). Together: a pressurer who re-enters before the defender's stance is restored forces the read to begin after initiation, where accuracy is lower, while the decision itself costs time and fatigue makes the response time unreliable. Population: trained boxers, kickboxers and MMA fighters in laboratory tasks; outcome: reaction time, decision time and recognition accuracy; boundary: no study measured a defender under live pressure, and the 14.7 percent is a change in reaction-time variability after upper-body fatigue, not a fight statistic.

Defensive accuracy depends on information available before the attacker's limb accelerates; shortening the gap moves the defender's sampling window past that point. Decision is a serial cost paid in milliseconds regardless of option, and fatigue adds variance to motor timing, so a required response that must fit a fixed arrival window fails more often even when the mean reaction time barely moves.

• S6Scientific Reports 2024: Speed of performing complex movement tasks under decision-making conditions as a determinant of the tactical preparation level in kickboxersopened, quote confirmedIn 47 Polish K-1 national team kickboxers (37 men, 10 women) deciding to start or change an action in reaction to an external stimulus significantly (p < 0.001) increased total task completion time; the time deciding to start and the time deciding during the action did not differ (2024).

If the page keeps a sentence about pressure forcing mistakes, it should say the mistakes come from the clock: the defender is made to read strikes after they start and to decide under a shrinking window, which is a timing failure, not a panic.

Pressure forces errors through the clock: a defender's read rests on cues before the strike starts, deciding costs time whatever is chosen, and fatigue widens reaction-time spread. This is the non-affective mechanism that bounds 'panic destroys thinking' from the pressure side and imports the defense as distance and time vector's A2 and A8 at higher weight than the defense as distance and time vector's clamped vector can carry them.

In 28 highly-trained male amateur boxers, nine 1-minute rowing bouts significantly reduced peak punch force for jab, cross and both hooks and delayed the time to specific force levels in every punch except the jab, with the larger effect in crosses and hooks that depend on trunk rotation (S7, INTERVENTION, within-subject). In elite boxers under a punching-fatigue protocol, anterior-posterior punch acceleration fell visibly from the sixth burst and jerk from the seventh, consistent with a lower rate of force development (S8, INTERVENTION). In nine professional Muay Thai fighters, 20 maximal roundhouse kicks at one per second or one per three seconds produced no difference in overall neuromuscular fatigue, only a different time course (S9, randomized cross-over). In 26 elite amateur boxers, clinch time and guard drops rose and bouncing fell across rounds (S1, CORRELATIONAL). Population: trained boxers and professional Thai fighters; outcome: punch force, rate of force development, countermovement jump, observed behaviours. Boundary: the fatigue in S7 was induced by rowing, not by an opponent's pressure, and none of these studies measured a fighter who was being pressured.

Punch force rides ground reaction force up a kinetic chain; when the legs and trunk tire the chain delivers less impulse to the hand, and the punches that need the most rotation lose the most. The count can stay high because the arm-extension jab survives, so output persists while danger falls.

• S8Fusing Accelerometry with Videography to Monitor the Effect of Fatigue on Punching Performance in Elite Boxers (PMC7601017)opened, quote confirmedIn elite boxers anterior-posterior punch acceleration decreased visibly from the 6th punch burst onwards and the slopes of acceleration (jerk) decreased from the 7th burst onwards, consistent with a reduced rate of force development under fatigue (2020).
• S9St Mary's University repository: Acute neuromuscular responses to short and long roundhouse kick striking paces in professional Muay Thai fightersopened, quote confirmedNine professional Muay Thai fighters in a randomized cross-over trial threw 20 roundhouse kicks at one every second (H1) or one every 3 s (H3); no difference between H1 and H3 in neuromuscular fatigue values, but CMJ height fell immediately after H3 and only from post-20 minutes after H1.

A page sentence that reads a fighter still walking forward as pressure still working is unsupported; the measured pattern is that the dangerous weapons fade before the count does, and a slower kicking tempo does not by itself buy economy.

Fatigue narrows the arsenal before it narrows the count: rotation-heavy punches lose force and force development first while the jab and the volume survive. The page's reading of a fighter still walking forward as 'relentless' pressure still working is unsupported; the dangerous weapons fade before the count does.

ONE judges score round by round on the 10-Point-Must system and, when the tally is equal, apply in order knockdowns, damage, number of clean strikes, then aggression and ring generalship; Muay Thai bouts use 4-ounce gloves and clinching, kickboxing 8- or 10-ounce gloves by weight class (S10, ARGUMENT, rules text). The ABC Unified Rules of Muay Thai (July 2024) state that a fighter with an advantage in the number or quality of knockdowns in a round shall never lose that round, then cumulative damage decides, then number and variety of clean techniques, and aggressiveness, control or effective defense only if those fail (S11, ARGUMENT, rules text). The instantiating record: on September 22 2023 Superlek, who missed weight for a 140-pound three-round catchweight, drove Rodtang to the ropes, landed a knee and then an elbow for an eight-count and won a unanimous decision, Rodtang's first striking loss in ONE (S13, bout record). Population: professional strikers under ONE and ABC rules; outcome: round and bout result; boundary: the rules texts are the payoff definition, not a measurement, and one bout instantiates rather than tests the law.

A scoring system is the function that maps constraint and damage to a result; when knockdowns and damage sit above activity, territory and workload are instrumental and a single conversion event erases rounds of unconverted pressure. Glove mass and clinch legality change which exits exist, so the same pressure has a different payoff under Muay Thai and kickboxing rules.

Any page sentence that treats forward pressure as a style that wins by itself must be reworded: pressure is instrumental under every opened ruleset, aggression is the last tiebreak, and the page should name the rules before comparing fighters across them.

The ruleset is the payoff function: knockdowns and damage outrank clean strikes and aggression ranks last, so pressure must convert within the round that pays for it, and glove mass and clinch legality change which exits exist. Any page comparison of two fighters across rulesets must name the rules first.

ONE's athlete records list Rodtang at 168 cm with a 134.9 lb limit and Tawanchai at 180 cm with a 154.1 lb limit, two divisions apart, and neither opponent column names the other (S23, S24, official records opened 2026-10-04). Rodtang: a left hook to the liver and a cornered flurry stopped Haggerty at 2:39 of round three in January 2020 (S22); Superlek drove him to the ropes, landed a knee and an elbow knockdown and won a three-round decision in September 2023 (S13); he walked Takeru down and finished him in 80 seconds in March 2025 (S14), against an opponent who had entered with broken ribs and a broken sternum (S16); in April 2026 Takeru blocked, absorbed and countered, dropped him twice with left hooks in round two, took his rounds three and four surge and stopped him at 2:22 of round five after four knockdowns, the first stoppage of Rodtang in 13 years (S15, S16). Tawanchai: a title decision in which Petchmorakot held the clinch midway and Tawanchai surged in round five (S25); repeated kicks to Kiria's blocking arm until it failed 29 seconds into round three (S20); a majority decision over Nattawut, whose low kicks to the lead leg set up straight rights (S21); a 10-piece combination for a third knockdown and a TKO at 1:10 of round two over Superbon (S17); a short left hook and follow-up that stopped him at 1:55 of round three after his teeps had controlled two rounds (S18); four inside leg kicks to the same spot as he closed distance, stopping him in 52 seconds in December 2025 (S19). Evidence class: official bout reports, CORRELATIONAL case records with no comparative coding of output, accuracy or position for either man; the per-minute strike figures circulating for both fighters carry no denominator and are not carried.

A style label records a recurrent preference in sequence selection; a result records who removed whose exits first under one ruleset against one opponent. Each preferred mechanism has a counter-geometry (a long guard and clinch against entries, a leg kick against the planted lead leg that distance control depends on, a pocket counter when the teep stops), so the label predicts the first exchange, not the outcome.

The page may keep the two names as examples of two preferences only if it stops implying they explain any fight: they never fought, Rodtang's pressure has been reversed by a long guard and by a counter-puncher, and Tawanchai's precision has produced attritional and high-volume finishes and been undone by a leg kick and a left hook.

The two named men never fought, sit two divisions apart, and each record contains the counter-geometry to his own label: a long guard and a counter-puncher reversed the pressure, a leg kick and a left hook undid the precision, and the precise fighter's finishes ran through attrition and volume. The page may keep the names as two preferences only if it stops implying they explain any fight.

Twenty-five certified international boxing referees (20 scoring judges and 5 supervisory officials) judged the same athletes in traditional and transparent roped rings across five predefined ring zones; with transparent ropes they awarded 1.2 to 1.5 more points per scoring zone and scored more consistently in every zone (p < .05, d 0.36 to 0.50), while under traditional ropes one zone's scores diverged from multi-angle video review (S12, INTERVENTION on the viewing environment, 2025). The winner-loser datasets that carry accuracy and ring-centre control are hand-coded from competition video (S1, S2), so a position variable and a scoring variable share the same sightline. Population: international boxing officials; outcome: points awarded per zone; boundary: one study, boxing not Muay Thai, no fighter-level test of whether cornering wins rounds through judges' eyes rather than through damage.

A judge scores what the sightline delivers; ropes and corners occlude the pinned fighter's work more than the pinning fighter's, so position enters the result twice, once through the exits it removes and once through the record of who landed.

Any claim that forward pressure 'wins rounds' on a judged record should be read with this lens: part of the credited advantage may be the judges' view, which no page sentence about Muay Thai has yet separated from the damage done.

Ring position enters the result twice, through the exits it removes and through judges' sightlines that drift by zone under traditional ropes; single-leg, so it is a caution on every 'pressure wins rounds' claim rather than a law, and it is the reason manual strike counts cannot settle the contrast.

In 108 international elite amateur bouts, defensive success rate was independently associated with winning (OR 1.18) alongside accuracy and ring-centre control, after adjustment for total punches (S2, CORRELATIONAL, 2026). In 20 elite boxers and 20 novices, recognition accuracy depended on seeing cues before action onset while fatigue moved reaction time, not accuracy (S5, INTERVENTION), so the operational content of composure is preserved information pickup under a shortened window. On the record, Takeru blocked, absorbed and countered Rodtang's entries, dropped him twice in round two, took a two-round surge and stopped him in round five (S15, S16), and Superlek gave ground to the ropes and converted a knee and an elbow into the knockdown that won a decision (S13). Population: elite amateur boxers for the measurement, two professional strikers for the cases; outcome: defensive success rate, recognition accuracy, bout result; boundary: no study measured 'composure' as a construct, the OR is per-unit of a coded rate, and the case attribution rests on two bouts.

A defender who keeps vision, balance, guard and exit timing holds his exit set open while the attacker spends energy and exposure to close it; the attacker's commitments are themselves cues, so composure converts the pressurer's loan into the defender's counter. The quantity that scores is the defensive action that succeeds and the counter it enables, never the posture of looking calm.

The page's lesson survives only as a defender's skill with a measurable face: keep the read, the base and the exit under a shrinking window so the attacker's commitment becomes your counter; it should not be written as the pressurer's gift or as the synthesis of two named styles.

Composure under pressure is the defender's instrument, measurable as defensive success and held exits, and on the record it belonged to the fighter receiving the pressure. This is the form in which 'the lesson is finding composure inside chaos' survives, and it pairs with the training composure vector's A1 (acting while alarmed) and the skill decay and return vector's A7 (a safety memory kept only by being tested).

Population: amateur boxers and MMA athletes (23 athletes, 896 video-verified events above 10 g), 13 MMA athletes, 22 novice headgeared military cadets, one elite Muay Thai athlete. Outcome: verified head impact counts per session and peak linear and angular acceleration from instrumented mouthguards. Evidence class: CORRELATIONAL field measurement. Male boxers took 18.4 +/- 13.1 verified events per sparring session with median peaks 19.7 g and 1,534 rad/s2 against 12.3 +/- 10.4 per competition bout at 17.1 g and 1,642 rad/s2; male MMA athletes 19.0 +/- 20.5 per sparring session at 17.5 g and 1,766 rad/s2 against 10.0 +/- 4.2 per bout at 37.9 g and 3,773 rad/s2 (medians of event peaks). In 13 MMA athletes sparring produced 298 events over 19 sessions (median 28.4 g) and competition 153 events over 11 bouts (36.8 g); 5 of 11 bouts ended in diagnosed concussion, none of 19 sparring sessions did. Headgeared cadets averaged 16.5 g with 640 of 809 events (79.1 percent) between 10 and 20 g and a 70.8 g maximum; the Muay Thai case logged 590 events, nearly all below 66 g, with maxima of 162.2 g and 26,850 rad/s2. Boundary: amateur and novice populations, unstructured 5 to 20 minute sparring, competition samples of 2 to 11 bouts, no professional Thai-stadium data, the Muay Thai case unverified by video and not poolable with 10 g-thresholded studies.

Each contact transfers momentum and angular momentum to the head; sparring repeats many low-energy transfers while competition delivers fewer transfers at full intent, so the exposure integral is dominated by training and the recorded injuries by competition. The event-magnitude distribution is right-skewed with a thin tail, so the mean peak describes almost none of the loading that matters.

A page that names the brain must say sparring is where the dose accumulates and must not say sparring is light because its typical hit is light.

Sparring is the high-count, low-magnitude arm of head exposure and competition the low-count, high-magnitude arm; the dose is right-skewed and its thin tail reaches the magnitudes seen in diagnosed concussions. Clamped with the vector for misquoted sources; a page that names the brain must say sparring is where the dose accumulates, without quoting counts.

Population: amateur boxers wearing mouthguard, skin-patch and headgear-patch sensors at once; cadaver heads under direct jaw impacts of the boxing kind; the Muay Thai single-athlete case; the combat-sport device literature. Outcome: share of recordings meeting quality criteria, validation slopes against a reference sensor, false-positive and false-negative mechanisms. Evidence class: INTERVENTION for laboratory validations, CORRELATIONAL for the field quality study, ARGUMENT for the conceptual paper, review for the 22-study synthesis. In boxing sparring 53 percent of mouthguard recordings, 20 percent of skin-patch and 26 percent of headgear-patch recordings met quality criteria and the low-quality recordings carried higher peak kinematics (p < 0.001). Under direct jaw impacts one mouthguard underpredicted (slopes 0.72 to 1.04) while another overpredicted every channel (slopes 1.4 to 8.7). Triggers of 5, 8 and 10 g across studies make counts incomparable; the Muay Thai case had no raw signals and no video verification. A sensor acceleration event approximates an in-vivo head acceleration event; false positives are mostly removable, false negatives are not, so research likely undercounts. Boundary: one sparring protocol for the quality shares; cadaver, not live, slopes; the undercount direction argued from mechanism, not measured in strikers.

A jaw-mounted sensor measures its own acceleration, which equals skull acceleration only when coupling holds; mandible motion, clenching, trigger thresholds and proprietary filters all enter the count, and because the biggest blows most disturb coupling they are the ones most often discarded, biasing exposure downward and dose-response slopes toward null.

The page may cite an exposure count only with its trigger and verification named; a bare 'hundreds of hits a week' is not a number under the number rule.

An impact count is defined by trigger level, jaw coupling, quality filtering and device, and the recordings discarded as poor are disproportionately the largest events, so every exposure figure is an undercount. The estimand law for brain dose, the same rule as the threat response under strikes vector's A4 and the strike force and impact vector's A5; clamped, and it is why no 'hits per week' figure may ride the page.

Population: 20 amateur boxers against 20 mock-sparring controls; 30 Olympic-style amateur boxers against 25 controls; 14 amateur boxers; 4 elite amateur Muay Thai athletes. Outcome: corticomotor inhibition and motor-unit recruitment (TMS and EMG), memory score, CSF and serum neurofilament light and GFAP. Evidence class: INTERVENTION (sparring versus mock sparring), CORRELATIONAL within-person repeats, a four-athlete feasibility series, cell and animal mechanism. One hour after three 3-minute sparring rounds the boxers showed increased corticomotor inhibition, altered motor-unit recruitment and poorer memory, back at baseline at 24 hours in that protocol. 1 to 6 days after a bout CSF NfL averaged 532 ng/L against 135 ng/L in controls and GFAP 496 against 247 ng/L; 77 percent of boxers had elevated NfL and nearly half remained elevated after at least 14 days of rest; none had concussion symptoms. Serum NfL was elevated 7 to 10 days after a bout against the three-month rested state, higher after more than 15 head hits. In four Muay Thai athletes the group-level GFAP-to-impacts association was negative. Mechanism: stretched axons break microtubules and degenerate while straightening back to normal appearance; injured tissue runs ionic flux and hyperglycolysis then depressed metabolism. Inference carried as inference: because NfL peaks over days and clears over weeks, a fighter sparring two or three times a week is sampled faster than the marker clears and the marker becomes a rolling integral. Boundary: amateur boxers, single sessions or bouts; the 24-hour return is for three rounds only; marker elevation is a response compatible with injury, not a neuron count or a disease.

Shear strain from head rotation stretches axons and disturbs astrocytes; the mechanical event lasts milliseconds, the cellular response (microtubule failure, ionic flux, metabolic depression, protein leakage) runs for days to weeks, and none of it requires a symptom to occur.

The page's cost line: a normal sparring session is not free to the brain even when nothing is felt.

One ordinary sparring session changes corticomotor inhibition and memory within the hour and one bout raises axonal and glial markers that outlast a two-week rest, with no symptoms in anyone. Tripwired on a source number; the page's cost line, that a normal session is not free to the brain even when nothing is felt, is the lead the training composure vector's A8 depends on and the sentence the page most needs to add.

Population: 7 competitive boxers over 16 sparring sessions with instrumented mouthguards and SCAT5 scales; 30 amateur boxers with symptom-free biomarker elevation; 631 American football brain donors as the shape of the law only. Outcome: total symptom severity change against session exposure; CTE presence against reported concussions versus estimated cumulative impacts. Evidence class: CORRELATIONAL (within-person repeated field sessions; brain-bank cohort). No group pre-to-post symptom difference (median change -1, p = 0.85); symptoms lower at 48 hours than before sparring; 4 of 16 sessions (25 percent) from 3 participants rose above 5 points (rises +5 to +17, mean 12 +/- 5); no correlation between symptom change and kinematics across the 16 athlete-sessions. In football donors reported symptomatic concussions were not associated with CTE presence or severity while years played and acceleration-weighted cumulative exposure were. Boundary: seven boxers and hypothesis-generating by the authors' own words; the donor series is selected and helmeted and transfers only its shape; athlete symptom reports carry a documented return-to-sport incentive.

Symptoms are a reported, incentive-laden output of a system whose biological state changes without them; averaging across sessions cancels large individual rises, and practice and reporting effects can move the score in the protective direction after exposure, so symptom change is decoupled from mechanical dose at the session level.

'I never got concussed' may not stand on the page as evidence of a safe exposure history; the honest tense is 'symptoms were not the meter.'

Symptom change did not track measured head kinematics across sparring sessions and symptoms were lower two days after sparring than before; 'I never got concussed' is not evidence of a safe exposure history. Tripwired; it is the same law as the threat response under strikes vector's A5 and the training composure vector's A5 for a different readout.

Population: 13 MMA athletes and the 5 concussive events simulated in finite-element brain models; football impact reconstructions and sensor datasets re-analysed in a 2025 preprint; a 2026 axonal strain model against above-8-g field impacts; the 22-study combat-sport review. Outcome: peak linear and angular acceleration at diagnosed concussion, modelled corpus-callosum strain and shear stress, 50 percent risk thresholds, modelled fibre strain at failure. Evidence class: CORRELATIONAL for bout-level kinematics, MODEL for the simulations. A concussed bout's highest-angular event had a linear peak of 50.5 g; a non-concussed bout contained a 105.7 g event; the injuring impact could not be identified. Concussion was associated with greater modelled callosal strain across 5 events. The 50 percent risk for peak linear acceleration was estimated at about 100 g (95 percent CI 89 to 110) against earlier 85 g (31 NFL reconstructions), 65 g (40 Australian football) and 192 g (helmet sensors). Axonal failure is modelled from about 6 percent fibre strain, with about 31.4 percent of above-trigger field impacts modelled to cause no callosal damage and the balance some sub-failure damage. The review states thresholds must not be used without clinical assessment. Boundary: finite-element and strain results are models; the 2025 and 2026 items were read at abstract level; threshold datasets are football, cited only for the spread.

Injury depends on the whole pulse (rotation, direction, duration) and on tissue state set by prior impacts, so peak linear acceleration is a weak summary and any g-threshold is a property of the dataset and instrument that produced it; sub-failure strain leaves damage that lowers the next impact's margin.

The page may not name a g-figure as 'the concussion line'; it may say the same blow injures one head and not another and the record cannot yet say which.

No single-impact concussion threshold exists for strikers: a concussing bout's largest hit was smaller than a non-concussing bout's, and published thresholds spread threefold by dataset. Tripwired; it receives the loading the strike force and impact vector's A6 describes and forbids any g-figure on the page as 'the concussion line'; 'iron chin' has no physics here.

Population: the Professional Fighters Brain Health Study (overlapping papers, never summed): 224 professional combatants and 22 controls cross-sectionally; 204 participants followed about 2.6 years; 140 active boxers, 211 active MMA fighters, 69 retired boxers, 52 controls; 94 active MMA fighters in a sparring-rounds cross-section. Outside it: 237 professional boxers at commission exams; 9 former professional boxers against 15 Alzheimer's and 14 subjective-cognitive-decline patients. Outcome: regional MRI volumes, computerised cognitive scores (processing speed, Trail-Making), plasma NfL and GFAP, Symbol Digit Modalities and balance. Evidence class: CORRELATIONAL (longitudinal within-person; cross-sectional; small comparative series). Active boxers lost left thalamus at 102.3 mm3 per year (p = 0.0004), mid-anterior corpus callosum at 10.2 (p = 0.018) and central corpus callosum at 16.5 mm3 per year (p < 0.0001) versus controls; higher baseline NfL predicted decline; caudate decliners worsened on Trail-Making. More fights, years or Fight Exposure Score tracked lower thalamic and caudate volume and slower processing speed, about 0.8 percent lower caudate volume per score point. Rising GFAP tracked volume loss and worsening cognition, chiefly in retired boxers. Self-reported cumulative sparring tracked worse Symbol Digit and balance scores in 237 professional boxers with a spline cutpoint near a Composite Sparring Index of 150. Nine former boxers had higher GFAP, p-tau181 and p-tau217 and lower volumes in every prespecified region with no difference in neuropsychological scores. In 94 active MMA fighters self-reported weekly sparring rounds were not associated with smaller volumes and were associated with a larger caudate after adjustment. Boundary: professional boxers and MMA fighters with careers underway at baseline, convenience recruitment, 22 controls in the cross-section, overlapping participants, no clinicopathological confirmation, no professional Thai fighters; exposure measured by fight counts and recalled sparring, never instrumented career integrals.

Rotational shear concentrates at the midline callosum and deep grey nuclei, so repeated exposure drives measurable within-person volume loss there and slows the relay functions those structures serve; but imaging and plasma markers are surrogates, skill training enlarges the same motor-learning structures injury shrinks, and active-fighter cross-sections are survivor-selected, so marker change and null proxies each bound what the gradient can claim.

The page may say years of continued fighting shrink specific deep structures and slow processing speed in the population record, and may not convert that record into a sentence about any one person's brain.

Over years of continued fighting the thalamus and corpus callosum shrink within the same fighter faster than in controls and cumulative exposure tracks slower processing speed, while a marker change is not a demonstrated impairment and a null on recalled sparring rounds is a statement about the proxy. Clamped; this is the population record the page may name in honest tense and may never convert into a sentence about one person.

Population: 45 male professional fighters who stopped sanctioned fighting and sparring for at least two years against 45 matched active fighters; 69 retired boxers in the 2023 PFBHS biomarker analysis; 9 former professional boxers with 5 followed about seven years. Outcome: computerised cognitive domains, plasma NfL and GFAP, regional volumes. Evidence class: CORRELATIONAL (non-randomised longitudinal; the transition was the fighter's own). The transitioned group improved on cognitive domains with decreasing NfL; the active group declined with stable NfL. Baseline GFAP was highest in retired boxers (mean age 49) and its rise tracked regional volume loss and worsening cognition in that group. In 5 former boxers plasma NfL and p-tau181 rose over about seven years without evident clinical decline. Boundary: stopping was self-selected and may travel with other health changes; the transitioned and retired groups differ in age, era and prior history, so they are two populations, not a contradiction; cessation is not shown to repair prior injury or remove later risk; the 'self-sustaining neuroinflammatory cascade' is an explanation, not a finding.

The axonal-injury signal (NfL) follows ongoing mechanical exposure and falls when exposure stops, while an astroglial signal (GFAP) and limbic volume loss in older retired boxers continue, consistent with an exposure-driven process that halts and a slower process set in motion earlier that does not.

The honest tense for reduced training is that an exposure that stops is followed by measurable recovery on some markers in the population record, not by a clean slate.

Stopping both fighting and sparring for two years is followed by cognitive improvement and a falling axonal marker, while an astroglial marker keeps rising in older retired boxers and tracks continued volume loss. Clamped; the honest tense for reduced training is measurable recovery on some markers rather than a clean slate, and it pairs with the skill decay and return vector's A4 on how conditioning drains and returns.

Population: boxing headguards on instrumented headforms in punch-machine tests; AIBA tournament rounds with and without head guards; headgeared, 16 to 20 oz-gloved military cadets; the 22-study combat-sport review. Outcome: peak linear and angular headform acceleration; referee stoppages for head blows per round and facial cuts; mouthguard peaks in novice sparring. Evidence class: INTERVENTION (laboratory), CORRELATIONAL (observational tournaments and field sparring), review. Tested headguards reduced both linear and angular headform acceleration in the laboratory, so the claim that padding cannot touch rotation is false there. In AIBA tournaments removing head guards was associated with fewer referee stoppages for head blows (the authors' surrogate for concussion) and more facial cuts; the quoted 0.38 percent of 7,352 rounds with guards against 0.17 percent of 7,545 without came from an unpublished internal study, and the earlier mandated-headgear era bundled computer scoring and rule changes. Headgeared novices averaged 16.5 g with 79.1 percent of events between 10 and 20 g and a 70.8 g maximum, compared by their authors to Service Academy football. The review calls the role of headgear in striking sports contentious. Boundary: punch machines, one tournament series, novice sparring; no opened study measures headgear against mouthguard-recorded cumulative exposure across a training block.

Foam lengthens the deceleration pulse and lowers peak acceleration of a given blow without zeroing the momentum transferred; a competition stoppage count is an officiating surrogate measured where headgear is least worn, and if protection changes what a fighter accepts, equipment and tactics are confounded in the same endpoint.

The page may not say headgear makes sparring safe and may not say it is useless; it may say headgear lowers a blow's peak in the laboratory and nobody has measured what it does to a season of sparring.

Headgear lowers headform acceleration in the laboratory and establishes no safe sparring dose; headgeared, heavily gloved novices still took football-band hits, the field case against headgear rests on a referee-stoppage surrogate, and no one has measured a season. Clamped; the page may say neither that headgear makes sparring safe nor that it is useless.

In adults who learned a complex coordination to a stable pattern (S3: 5 adults, 390 minutes of ski-simulator practice; S4: 16 adults, 225 minutes of bimanual 3:2 practice; S5: a polyrhythm case series), the learned coordination mode was expressed on the first retention trial after 3 months (S4), 8 years (S5) and about 10 years (S3), while in the same tests movement amplitude and frequency had declined (S3) and the slowest-learned variable, intermanual crosstalk suppression, was the only one not maintained at 8 years (S5). Over the same kind of interval, supporting conditioning in elite taekwondo fell (S7: estimated aerobic power down about 2.43 percent of baseline in 16 black belts after 8 weeks of cessation; S6: endurance fell more in the cessation arm than the ~7 h/week arm over 12 weeks) and tendon stiffness and muscle cross-section returned to pre-training values at one and two months of detraining while strength and neural activation held (S13). Boundary: the retention studies are laboratory coordination tasks with no opponent, threat or impact; S3's cohort skied occasionally and had a 5-month retention test, so '10 years' is not zero related exposure; the slowest-learned-goes-first finding rests on one case series (S5) and is carried as a bound, not a law. Evidence classes: INTERVENTION within-person (S3, S4, S5, S6, S7, S13).

The components rest on tissues with different turnover: mitochondrial enzymes and plasma volume turn over in days to weeks (S19), tendon collagen in months (S13), and the cortical synaptic structure encoding a practiced movement is selectively stabilized and persists after training stops (S35, mice; S36, songbirds). The observed skill is the envelope of these curves, so time away cannot be read as one number; what stopped and what continued must be named per component.

Any page sentence saying a striking skill was kept or lost must name the component. The page may say the trained pattern of a strike is the most durable part of the skill; it may not say the skill as a whole is retained, and it says nothing about any individual's present ability.

A learned striking skill has no single decay constant: the coordination pattern persists for years while output, conditioning and calibration drift on separate clocks. Capped by a misquote elsewhere in the vector and refuted by the adversary as a universal, it still carries the page's honest tense for an interest trained less: 'the movement is still there' can be true in a body whose conditioning and tissue tolerance are not.

Across 1,344 effect sizes from 457 reports of procedural skills with motor components in adults (S1, random-effects metaregression with retention interval as a continuous predictor), the acquisition-to-retention performance difference grew by 0.08 standard deviations per month of nonuse for accuracy measures and 0.06 SD per month for speed and mixed measures, so half of the initial acquisition gain was lost after about 6.5 months (accuracy), 13 months (speed) and 11 months (mixed). Across 189 data points from 53 articles (S2), loss ran from d = -0.01 immediately after training to d = -1.4 after more than 365 days of nonuse, physical, natural and speed-based tasks were less susceptible than cognitive, artificial and accuracy-based tasks, and retention tests run under conditions matching training showed less loss. Boundary: both estimates pool heterogeneous laboratory and occupational tasks, not striking; the denominators are the initial acquisition gain (S1) and the acquisition-to-retention difference in SD units (S2), never a share of an expert's total ability; S1's authors name relearning contamination of retention scores and speed-accuracy trade-offs as live threats. Evidence class: CORRELATIONAL (meta-analyses of retention studies).

Accuracy demands a current calibration of magnitudes and timings against a target, an error-driven and volatile state; speed on a natural continuous task reflects a stabilized coordination structure (A1). Retrieval is context-gated: the stored skill includes the cues present at training, so a changed environment adds a retrieval failure that reads as decay (S2, converging with S28).

The page may state, with these two sources, that time away costs accuracy and reading before it costs speed and gross movement, and that across procedural tasks half of a learned accuracy gain is typically gone after about half a year of nonuse. It may not quote those months as a Muay Thai figure or as anyone's present ability.

Nonuse erodes accuracy-based performance faster than speed-based, and a retrieval context that matches training reduces apparent loss; the half-loss intervals come from pooled procedural tasks and are never a Muay Thai figure. Time away costs aim and reading before it costs gross movement, which is the shape 'ring rust' takes.

In 70 younger and older adults who first trained resistance exercise three days a week for 16 weeks (S8, randomized), 32 weeks at one-third or one-ninth of that weekly dose with loading intensity preserved maintained hypertrophy in the younger adults and not the older, and maximal strength was largely retained even in the cessation arm; in trained adults (S9) isometric lumbar strength held over 12 weeks at a frequency as low as once every four weeks with per-session intensity and volume maintained, while the detraining group lost 55 percent of its gain; after 12 weeks of concurrent training (S10) one session every two weeks for three months preserved 90 to 95 percent of strength and aerobic-power gains and 72 percent of the muscle-mass gain. In the companion ballistic design (S11) both reduced frequencies produced significant losses of power performance and one session a week was needed to hold it. In elite taekwondo (S6, 11 athletes) about 7 h/week of isolation training held a light-cued kicking response over 12 weeks while endurance fell more in the no-training arm. Boundary: resistance- and aerobic-trained adults plus one small elite taekwondo cohort; no opened study measures the minimum live-partner dose that holds opponent timing, distance calibration or composure (UNVERIFIED after search by two legs); S6's response measure bundles reaction and movement time and keeps the best of three kicks, so it is not cold first-trial retention, and small groups mean non-significance is not equivalence. Evidence class: INTERVENTION (randomized dose arms).

A magnitude adaptation (how much force, how much oxygen) is a tissue stock a periodic high-intensity signal can keep topped up; a rate adaptation (force per unit time) depends on neural timing and synchronous motor-unit recruitment that decays between exposures and needs frequent re-tuning. A strike is impulse delivered into a closing window, a rate quantity, so the components reduced practice protects best are the ones a striker needs least and the one it fails to hold at low frequency, power, is the one the strike is made of.

The page may say that keeping intensity on a much smaller schedule holds strength and endurance, and that explosive power needs the schedule more than the stock does. It may not say reduced practice preserves 'the skill', and nothing in the opened record licenses a sparring dose.

Reduced practice with held intensity keeps strength and endurance on a fraction of the dose while ballistic power falls at the same frequencies, and no study measures the live-partner dose that holds timing or composure. Tripwired on a source number; a lead that separates 'training less' from 'stopping' and says the component a small schedule protects least is the one a strike is made of.

In 11 well-trained soccer players after 7 days of cessation (S15, within-person), repeated-sprint total time worsened from 45.7 to 48.0 s and the fatigue index from 5.8 to 7.8 percent while 5 m and 10 m sprint times improved (1.05 to 1.02 s; 1.79 to 1.74 s) and agility, coordination, Yo-Yo IR2 and knee peak torque did not change. In 18 professional players after 4 weeks (S16), jump height and sprint times were unchanged and half-squat peak force and mean power at 50 and 100 percent body mass rose (effect sizes 0.55 to 0.82). In endurance-trained adults (S19, tabulated cessation studies), VO2max fell about 7 percent of baseline by 12 to 21 days, driven largely by plasma-volume and stroke-volume loss, and to about 16 to 20 percent by 56 to 84 days. By 8 weeks elite taekwondo black belts lost about 2.43 percent of estimated aerobic power (S7); by 12 weeks 14 elite swimmers lost swimming speed and power, lactate-threshold speed, jump height and upper-limb power with no change in body weight or composition (S17); after 24 weeks 38 older adults lost 15.5 to 17.8 percent of trained power and 16.5 to 17.1 percent of strength, regained with comparable accrual in 12 weeks of retraining (S18); after a 10-week interruption, strength and size losses were regained mostly within the first five weeks of retraining (S12). Boundary: soccer, swimming, endurance and older-adult populations plus one elite taekwondo cohort; the early rise in single-effort output is an end-of-season fatigue release and does not transfer to a mid-year layoff without the same accumulated fatigue; body composition is not a readiness proxy (S17). Evidence class: INTERVENTION within-person, plus a CORRELATIONAL review table (S19).

Plasma volume and mitochondrial enzyme activity turn over in days (S19), so the capacity to repeat efforts and recover between them is the first stock to drain; maximal strength and single-effort speed rest on neural drive and contractile protein that hold for weeks, and a rested nervous system can briefly express more of them. Over two to three months contractile and elastic capacity follow, without visible atrophy.

The page may say a layoff drains the ability to repeat efforts and recover between exchanges within a week or two, long before a single strike loses its force, and that visible shape is no evidence of readiness. It may not describe a universal week-by-week schedule.

Under full cessation repeat-effort capacity and the cardiovascular stock drain within a week or two while single-effort force holds for about a month, then falls over two to three months without visible change in shape. Refuted as a universal schedule; carried as the order of conditioning loss, with the brain under head impact vector's A7 as the brain-side recovery it pairs with.

In young adults who trained isometrically for 3 months and then stopped for 3 months (S13, within-person), maximal strength and neural activation did not change during detraining while muscle cross-sectional area and tendon stiffness fell back to pre-training values at one and two months respectively; the authors conclude tendon and muscle morphology adapt more slowly to training and de-adapt faster than muscle function. In collegiate overhead athletes through the COVID cessation (S14, natural experiment), shoulder and hip range of motion changed more than strength, in the injury-associated direction, and resumed team training reversed some but not all of it. In 20 elite Greco-Roman wrestlers (S38), 14 weeks of restricted activity was followed by 8 weeks of retraining in which the Specific Wrestling Fitness Test rose from 31.40 to 37.40 while heart-rate variability, depressed in cessation, recovered through retraining. Retraining records converge on weeks for the force side: strength and size regained mostly within five weeks after a 10-week interruption (S12), and support staff of elite Japanese team and combat athletes reported about two months to regain strength and power after the pandemic interruption (S37, interview data, ARGUMENT class, weak signal only). Boundary: S13 is isometric knee-extension training in young adults, not impact loading; no opened study measures hand, wrist, shin or neck tissue tolerance across a striker's layoff (UNVERIFIED); S38 measures a wrestling fitness test, not tissue. Evidence class: INTERVENTION within-person (S13, S38) and CORRELATIONAL natural experiment (S14).

Tendon has a far lower cell-to-dry-mass ratio, vascularity and turnover than muscle, so its stiffness lags muscle function on the way up and falls faster on the way down (S13). The force a strike delivers is also the reaction force the hand, shin and neck absorb, so a returning striker can regain the capacity to generate impulse before the tissue that receives it has re-stiffened; the hazard window is the gap between the two clocks, a structural consequence of differential time constants.

The page may say that after time away the body regains the power to deliver a strike before it regains the tissue tolerance to deliver and receive it, and that this gap is where injuries on return live. It may not give a tolerance timetable for strikers.

Force-producing capacity outlasts and returns ahead of force-absorbing tissue, so a returning striker regains the power to deliver a strike before the tendon and tissue that must take its reaction force have re-stiffened. It survived the adversary; the hazard window on return lives in that gap, and the page may say so without a tolerance timetable.

In adults adapting to a visuomotor rotation (S20, five experiments) savings reflected improved action selection, recalling an appropriate aiming strategy, not faster implicit adaptation; savings required a prior history of error rather than repetition of successful actions (S21), and experiencing an error durably raised sensitivity to that same error (S22). Savings and long-term memory doubly dissociated (S23): the fast, temporally volatile component drove faster relearning but not next-day retention, and the slow component drove retention but not savings, while a history of errors modulated both processes in force-field reaching (S27). How adaptation was removed decided whether savings survived: washout by removed feedback or error-clamp trials left none while gradual reversion did (S24). In 40 adults on a split-belt treadmill (S25, randomized four-arm) four 7.5-minute exposures on one day produced day-5 savings comparable to repeated 30-minute exposures across days at one quarter the adaptation time, and consolidation of a new internal model required practice beyond the performance plateau with a longer inter-session interval making it harder to reactivate (S26). Boundary: laboratory reaching, tracking and locomotor adaptation in adults over minutes to days, never months of natural nonuse; no study measures savings in a striking skill after a documented layoff; the '80 percent fewer trials' figure in one leg is a within-paradigm count from a fitted two-state model (MODEL class) and is not a striking number. Evidence class: INTERVENTION plus MODEL.

Two processes with different time constants adapt to error (S23, S27): a fast one that learns and forgets quickly and a slow one that learns and forgets slowly. Savings arises when the fast process is re-engaged by a recognized perturbation and by raised error sensitivity, so the returning performer re-tunes quickly without the tuned output having been stored. The engine of re-tuning is the error signal itself; in striking the calibration error of distance and timing is being hit, so the savings signal is paid in head impacts (an inference carried to the brain vector).

The page may say a returning striker relearns faster than a beginner because the system remembers what to do and is primed for its old errors, and that this is not the same as having kept the skill; the fast return of a familiar gross pattern is evidence of savings, not of preserved precision under pressure. It may not quote a trial or session count for the return.

Relearning is faster than first learning because the system recalls a strategy and is primed for its old errors, and this savings is dissociable from retention; in striking the error signal that drives it is being hit. The kernel of 'it comes right back' survives as savings, not as restored precision under pressure, and its cost links to the brain under head impact vector's dose.

In human and animal fear conditioning (S28, S29, S31) extinction does not erase the fear association; it lays down a second, context-specific inhibitory memory that competes with it, so extinguished responding returns with the passage of time (spontaneous recovery, a change of temporal context), with a change of background context (renewal), after a single unpaired aversive event (reinstatement), and the original response reacquires faster than it was extinguished; unrelated stress outside the learning context strengthens spontaneous recovery (S30). In 27 police officers (S32, randomized two-arm, 4 one-hour sessions, 48 training shots, 4-month retention) the group that shot against an opponent who sometimes fired painful marking cartridges kept its accuracy under the anxiety manipulation at retention while the control group's accuracy fell under anxiety, and reported anxiety stayed higher in the threatening condition for both groups: regulation meant performing despite anxiety, not removing it, and the control group also improved by retention, so the exclusive advantage is bounded. Boundary: fear-conditioning laboratories and one police-trainee intervention; no opened study measures composure under strikes across a documented layoff in fighters (UNVERIFIED after search by three legs); the Cooper colour-code heart-rate bands in one leg are ARGUMENT and carry no measured threshold here. Evidence class: INTERVENTION (S32, conditioning experiments) and CORRELATIONAL review (S29).

Threat learning generalizes and safety learning is tied to the context in which it was learned (S28), so composure built in one room against known partners is the component most exposed to a layoff: time alone shifts the temporal context that gated the safety memory, a new room or partner removes the cues, and one bad exchange on return reinstates the old response. This makes composure the one component that can be worse after an interruption than a disuse model predicts, and it cannot be kept by solo practice, which contains no incoming threat to extinguish. Adjacency named: The Physics of Flow States (February 2026) treats arousal regulation in non-combat performers and is silent on retention; this axiom bounds that frame by name for the combat case, where the regulated state is an actively maintained, context-gated inhibitory memory, not a stable trait.

The page may say that calm under fire is learned safety the brain keeps only while it is being tested, that time, a new setting or one bad exchange can bring the old response back, and that the training effect that survives is performing while anxious rather than not being anxious. It may not say composure, once learned, is kept like a movement.

Composure under incoming strikes is extinction learning: a context-specific safety memory that time, a new setting or one bad exchange lets the generalizing fear memory overrun, with fear reacquired faster than safety; the threat-trained benefit that survived months was performing while anxious, not being unafraid. Capped and refuted as a universal, it is still the mechanism behind the training composure vector's A4 and A6, the cross-vector reason 'override' fails, and this run's bound on The Physics of Flow States by name.

In karate athletes tested in situ with temporal occlusion (S33, cross-sectional expert, near-expert, novice) experts anticipated above chance at every occlusion point, near-experts only at the two latest points and novices only at the last; expert anticipation did not differ from near-experts at the earliest occlusion point but did at all later ones. Methodologically (S34) expertise effects are larger when the response is a coupled movement than an uncoupled verbal or button prediction, and occlusion methods that preserve perception-action coupling and binocular depth cues are what reveal expert performance. From these follows a bound on reduced practice: film study, shadow work, bag work and compliant pad work decouple perception from the opponent's kinematics and therefore maintain coordination (A1) and conditioning (A3, A4) but not the anticipation component. Boundary: the combat-sport anticipation literature is cross-sectional expert-versus-novice and training-intervention work; no opened study measures the decay of combat anticipation across a documented layoff (three legs searched and found none), so the rate of loss is UNRESOLVED and the 'two to four weeks' figure in one leg has no primary source; expert-to-novice contrasts describe a population difference, never an individual's present read. Evidence class: CORRELATIONAL (S33) and ARGUMENT grounded in intervention methods (S34).

Anticipation is early pickup of kinematic information from a specific moving body in depth, mapped to a response (S33, S34); it is not a stored file retrievable without the information field. Removing the opponent removes the input the skill is made of, so the exposure that preserves it is live, coupled work and no other exposure substitutes. By A2's task-type ordering it sits in the cognitive, accuracy class that loses most with nonuse, an inference from pooled tasks, not a combat measurement.

The page may say that reading an opponent is the one part of striking only a live opponent keeps sharp, and that its loss over time away has not been measured. It may not state a weeks figure for the loss of timing.

Anticipation lives in the coupling of perception to a live moving opponent, so bag, pad and shadow work cannot maintain it, and its decay across a layoff has never been measured. Single-leg; the same axis the training composure vector's A7 and the defense as distance and time vector's A3 describe, with the retention gap as its finding, and the reason the page may say reading an opponent is the one part of striking only a live opponent keeps sharp.
