Training for 100 m, 200 m and 400 m
Give every session one purpose, train speed fresh, feed it with heavy strength and jumps, keep the Nordic in the week, and add 400 m special endurance on top of speed rather than instead of it; the session recipes are coaching practice, not tested doses
The question it answers
How should a 100, 200 or 400 m runner train: what decides each distance, which session types do what, where strength, jumps and Nordics fit, what the 400 m adds, what goes in the warm-up, and what changes for masters and youth. An endurance athlete asking for "some sprint work" belongs in SYNTH-46, not here.
What decides each distance
All three: sprint performance is heavily genetic, yet power, technique and sprint-specific endurance are trainable, and an elite sprinter's year-to-year change is smaller than the typical variation, the smallest worthwhile change and the effect of wind or timing method (REF-763, B+, narrative review of science and elite practice, Tier 4-5).
100 and 200 m: in all-out work the anaerobic system predominates up to about 75-80 s, with equal contribution at 78.6 s (REF-460, A-, 102 studies, no running/cycling or training-status difference).Inference: both events sit well inside the anaerobic-dominant window, so speed and power are the ceiling. Top speed is a ground-force problem: in 33 runners (top speeds 6.2-11.1 m/s) the fastest applied 1.26 times more vertical force per body weight during contact, while leg swing time did not differ (REF-805, B, treadmill, cross-sectional). Acceleration is a force-direction problem: in 12 active men (2 sprinters), keeping force pointed horizontally as speed rose correlated with 100 m speed (r > 0.731), total force did not (REF-806, B, correlational).
400 m: in 16 trained 400 m athletes (11 men, 5 women) the aerobic/anaerobic split by accumulated oxygen deficit was 41/59% in men and 45/55% in women (REF-767, B, time-trials, not races).With elite-style pacing, trained runners slowed to 77% of peak velocity in the last 100 m and VO2 fell 15.6% there (REF-771, B, sample size not in the abstract, one pacing profile tested).In 6 trained male sprinters at 400 m race speed, leg force was already falling in the first 100 m, more neural drive covered it until about 200-300 m, then speed dropped; fatigue sat mainly in the muscle, and drop-jump loss tracked lactate (r = −0.77) (REF-807, B).In video of 400 m races (6 groups of 5), world-class runners passed 200 m at 96.3-97.6% of their best 200 m speed and faded more than national and regional runners (fatigue index 22.99% vs 14.43% and 13.91%) (REF-803, B, descriptive).So the 400 m needs top speed, tolerance of the late fade and a real aerobic share — the fade itself is the normal shape of the race, not proof of a pacing error (REF-771 practice line).
Default (what to prescribe first)
The organising rule is from REF-763: elite practice ties each session's modality, duration, intensity, recovery and session rate to a stated purpose (acceleration, maximal velocity, sprint-specific endurance, technique), whereas most studies test brief maximal sprints with short recoveries in young team-sport athletes. [REF-763]'s abstract contains no volumes, distances or recoveries — every number below is not from a study.
Not from a study; the base's own practice, for a Tier 1-3 club sprinter in the preparation phase:
2 speed sessions a week (one acceleration-led, one max-velocity-led), done fresh, first in the session, near-full recovery between reps; stop when times or form drop.
1 speed-endurance session for 100/200 m runners, 2 for 400 m runners, never the day before a speed session.
The Nordic hamstring exercise inside the regular prevention routine (REF-766); placing it away from the key speed day is an inference in that entry, not a finding.
The remaining days easy running, technique drills or rest.
Decision (who → what)
| Situation | What to do | Source and strength |
|---|---|---|
| Any sprinter, any phase | Write the purpose first, then distance, intensity and recovery to serve it | REF-763 B+, narrative, no numbers; the session contents are practice |
| Any sprinter: what to build the plan on | Sprinting itself is the core; gym and jumps are additions | REF-804 B+ (48 training studies, 1,485 subjects, mostly non-sprinters; not a formal meta-analysis): specific sprint training (free, resisted, assisted) ES −1.00 (−3.23%); resistance/plyometric alone best at 31+ m (ES −0.43); combined best at 0-10 m (ES −0.59, −2.81%) |
| Poor acceleration, or a force deficit on a split-time profile | More short accelerations, paired with strength/power work; a sled is one option: moderate to very heavy loads (10% to >30% body mass) gave 0.5-9.1% acceleration changes in strength-trained and team-sport athletes, but sled sprinting has not been shown to beat the same sprints without a sled | REF-765 A-, SR of 11 small studies; REF-804 B+: combined sprint + strength/power training had its largest effect over 0-10 m (ES −0.59); horizontal force direction as the determinant REF-806 B; profiling REF-553 B+ (methods only); the force/velocity-deficit branch is practice |
| Poor top speed, or a velocity deficit | Maximal-velocity sprints on long recovery (flying sprints are practice) plus heavy strength and jumps; in sprint-trained athletes light sleds (<10% body mass) gave +2.4% maximal velocity | REF-765 A-; REF-805 B: vertical force per body weight, not swing time, separated fast from slow runners — inference in that entry that force-building work is the route, untested; the flying-sprint prescription is practice |
| Weak in the gym | Raise the squat: across 15 studies (510 subjects) squat-strength gains tracked sprint gains (r = -0.77) and resistance training improved sprint performance by 3.11% on average; sessions per week, rest between sets, body mass and level of practice moderated it, %1RM did not | REF-764 A-, populations and distances not given in the abstract; dose → SYNTH-44 |
| Every sprinter | Plyometrics: in 30 RCTs in track-and-field athletes, 30 m sprint −3.53%, CMJ +5.11% | REF-518 A; drills and contacts → SYNTH-45 (practice) |
| Every sprinter | Nordic hamstring exercise in the prevention programme: injury risk ratio 0.49 (0.52 in the 8 randomised studies) across 8459 athletes, women and men, several sports | REF-766 A; no dose in the abstract; REF-887 A-: across 13 studies low- and high-volume Nordic training gave similar very large eccentric-strength gains after ≥6 weeks (g = 2.28 vs 2.12; adaptations, not injuries; volume bands and populations not in the abstract) — so a low volume kept up; sets and reps are practice or from a clinician |
| 200 m and especially 400 m | Speed-endurance work above the VO2max intensity: in trained athletes it improved 20-60 s and 1-10 min events even on reduced volume, with no VO2max change; "production" (10-40 s, long recovery) and "maintenance" (5-120 s, shorter recovery) sub-types are from REF-697's full text | REF-697 B, REF-695 B, narrative reviews, not sprinter trials; placement and weekly dose are practice |
| 400 m race, athlete who tolerates it | Sodium bicarbonate 0.3 g/kg, 60-180 min before; effects established for 30 s-12 min; rehearse in training (GI side-effects) | REF-354 A, position stand; the 400 m falls in the window by duration (inference — no 400 m trial here). Inference by duration: a 100 m is outside the window; a 200 m (about 20-30 s) falls just below it |
| 400 m race plan | Accept a fast first 200 m and a fade; build the capacity to hold it before asking for the elite split (practice; described in elites, not tested) | REF-803 B (world-class: 96-98% of 200 m-best speed at 200 m, largest fade); REF-810 B+ (elite 400 m pacing is positive); a lower-level runner copying it is untested |
| 400 m, planned months ahead | β-alanine: in 0.5-10 min efforts capacity tests ES 0.50 but performance ES 0.11 (CI crosses zero); with bicarbonate ES 0.43; needs chronic loading | REF-351 A; small effect — not a priority over training |
Warm-up
Short and specific is enough. In track cyclists a 15-min warm-up with one sprint gave 1390 vs 1303 W Wingate peak power after a ≥50-min warm-up with 4 sprints (REF-276, B, cycling — a transfer); in 12 soccer players a short sprint-specific warm-up matched a long specific one on 40 m times, beat a long general one and felt easier (REF-287, B). SYNTH-46 uses the same rule.
Optional potentiation for stronger athletes: a conditioning activity gave a moderate sprint boost (ES 0.51), larger in stronger, more experienced lifters; plyometric conditioning activities potentiated slightly more and sooner (REF-688, A, 47 studies, benefits acute; recovery windows not in minutes in the abstract).
400 m: a continuous race-pace 200 m in the warm-up made an 800 m time-trial 1.2 s faster than strides alone in 11 highly trained middle-distance runners (REF-285, B). Inference, untested at 400 m: one sustained race-pace effort may help a 400 m too; keep it well short of fatiguing.
How to progress / periodise
REF-763 names progression, specificity, variation/periodisation and individualisation as the principles used in elite practice; it gives no phase lengths.
Not from a study; the base's own practice: general preparation leans on strength, plyometrics, short accelerations and extensive tempo; specific preparation adds maximal velocity and grows speed endurance (more of it for 400 m runners); in the competition phase volume falls and speed quality is kept. No sprint taper study is in this base (SYNTH-34 is endurance-derived).
Judge progress over seasons, in comparable conditions — annual change is below the typical variation and the effect of wind (REF-763); one wind-assisted time says little.
Masters: keep the intensity and widen the gaps, with recovery signals rather than age as the trigger (SYNTH-35, C+); keeping maximal sprints in a masters sprinter's week is our application of it. Ageing tendon adapts and heals slower; progressing hard sprints and jumps gradually is an inference in REF-599 (B–C, mechanistic review, no masters trial).In 91 male sprinters aged 18-84, fast-fibre size, maximal isometric force and rate of force development fell with age despite sprint training, though muscle stayed at a high level (REF-808, B, cross-sectional); its inference, untested: heavy and explosive strength defends speed.In adults ≥50, high-velocity resistance training raised leg power more than slow training (Δ 0.62 vs 0.20) (REF-597, A+, mostly untrained — a transfer). The base holds no masters-sprinter training study.
Youth: supervised, technique-first resistance training is safe and does not stunt growth (REF-600, A, consensus, full-text statements), and strength trainability rises with age and maturity with no special pubertal boost (REF-601, A).In 1190 young athletes, weekly organised hours above age in years roughly doubled the odds of serious overuse injury (OR 2.07) and single-sport specialisation raised injury odds (OR 1.27) (REF-602, B+, case-control). Inference: a young sprinter's speed work stays low in volume inside a varied programme.
When NOT to use it / red flags
Hamstring pain or tightness that changes sprint mechanics: Not from a study; the base's own practice — no maximal sprinting until it settles; see a clinician for a suspected strain.
Maximal sprints right after unaccustomed heavy eccentric hamstring work: after leg curls to exhaustion in 24 subjects, semitendinosus stiffness peaked at 48 h and normalised only at 96 h while tightness felt worst at 24 h (REF-322, B); keeping 72-96 h is that entry's practice line, not a finding.
Speed work on tired legs (after speed endurance, heavy lifting or a hard 400-type session the day before) — practice; the session's purpose is lost.
Bicarbonate first tried on race day — rehearse it (REF-354).
Genetic tests to decide who is a sprinter: ACTN3 RR is only modestly enriched in power athletes (OR 1.48) and does not predict the individual (REF-433, A-).
Team-sport repeated-sprint studies used as a sprinter's template — the population gap REF-763 names; inference, the transfer is not measured.
What the evidence does and does not show
Shows: sprinting itself improves sprint times most, gym and jumps add to it (REF-804); top speed goes with vertical ground force, acceleration with horizontal force direction (REF-805, REF-806); strength (REF-764) and plyometric (REF-518) gains transfer to sprint times (30 m for plyometrics; distances not given for the strength meta-analysis); the Nordic halves hamstring injury rates (REF-766); the 400 m is majority anaerobic with a large aerobic share (REF-767); speed endurance helps short-event performance in trained athletes without moving VO2max (REF-697, REF-695); bicarbonate covers 30 s-12 min efforts (REF-354).
Does not show: any dose — reps, distances, recoveries, weekly count — for sprint sessions; that sleds beat plain sprinting (REF-765); anything tested in trained women sprinters beyond pooled samples (REF-767's 5 women); a 400 m pacing strategy that beats another (REF-771 tested one profile; REF-803 compared levels, not strategies); a masters or youth sprint-training trial (REF-808 is cross-sectional); that raising ground force raises top speed (REF-805 is cross-sectional).
Evidence gaps
Sprint-method comparisons in trained track sprinters (REF-804 is mostly non-sprinters and not a formal meta-analysis).
A masters-sprinter training study (REF-808 is cross-sectional, men only); women sprinters generally.
A Nordic dose in reps and sets, and a Nordic trial in sprinters (REF-887 does not define its volume bands); a sprint-specific taper; bicarbonate or β-alanine trials in the 400 m itself; special-endurance session trials at 400 m level (thin in the literature itself).
How this entry was checked and changed
Why this level
(A-/A meta-analyses and an A position stand for the add-ons — strength, plyometrics, Nordic, buffers — but the core of the plan, session design and weekly structure for sprinters, rests on one B+ narrative review without numbers plus house practice; this base was built for endurance athletes)
Content correction 2026-09-27
Revision 2026-09-29: folded in REF-805 (Weyand 2000, top speed = vertical ground force) and REF-806 (Morin 2011, acceleration = force direction) into "what decides"; REF-807 (Nummela 1992) and REF-803 (Hanon & Gajer 2009) into the 400 m (fade starts early, within muscle; elite go out faster and fade more) with a new 400 m race-plan row; REF-804 (Rumpf 2016: sprinting is the core, gym adds; combined best at 0-10 m) as a new row and in the acceleration/top-speed rows; REF-887 (Cuthbert 2019: low-volume Nordics as effective) in the Nordic row; REF-808 (Korhonen 2006) in masters; REF-810 (Casado 2021) for 400 m pacing.Four candidate gaps closed; remaining gaps restated. Default and level (B-) unchanged — the week itself is still practice.
Verification 2026-10-01: all 33 cited REF entries were read in the snapshot. Every number in 'What decides each distance', the 11 decision rows, warm-up, masters/youth and red flags matches the cited entry (n, population, effect sizes, level), apart from the findings listed.
Verification 2026-10-01: the Default (weekly structure) is entirely labelled practice and the SYNTH says so three times (title, Level line, bold line under REF-763). Decision rows: 5 evidence (sprint-is-core, squat, plyometrics, Nordic, β-alanine), 6 mixed (purpose rule, acceleration, top speed, speed endurance, bicarbonate-by-inference, 400 m race plan), 0 pure practice. B- matches that; no LEVEL-OVERALL finding.
Verification 2026-10-01: population transfers are stated in place (cycling warm-up, soccer warm-up, mostly-untrained older adults, team-sport sled studies, endurance-derived taper).
Verification 2026-10-01: the only finding that could change what an athlete does is the bicarbonate line: a 200 m is under the 30-s lower bound of the position stand's window, so 'short edge' should read 'just below'.
Verification 2026-10-01: REF-354's header byline (Hadzic 2019 / Grgic 2020) differs from the source the entry is written from (Grgic 2021 ISSN stand, DOI present); numbers used by the SYNTH are the stand's.
2026-10-01: level tags next to cited frameworks updated to their current levels after the independent audit.
