WERP is this swimmer's individual aerobic velocity ceiling — the fastest pace sustainable without depleting W′. Training below WERP builds the aerobic base. Above WERP burns the finite anaerobic reserve. CS marks where lactate clearance equals production.

Coaching insight: W′ is exhausted at ~147m. The swimmer cannot hold target pace for the full 200m at this intensity. Either extend W′ through severe-domain interval training, or race the first 110m at WERP pace then accelerate — preserving W′ for the final push.

🎯
Race-pace control sets — lock in target velocity 4–6 × 100m at exactly 1.726 m/s (57.9s/100m), 60–90s rest. Aerobic system holds this pace — the goal is neuromuscular economy at race speed, not metabolic stress.
⚡
Build anaerobic power — W′ is the limiting factor 8–10 × 25m all-out, 3–4 min full recovery. W′ of 18.4 kJ is exhausted at ~147m at race pace — extending W′ through maximal sprint training is the highest-priority adaptation.
🔄
Stroke rate: raise to 44 c/min (current 37.1 c/min) SR below 200m Free floor (40 c/min). Higher turnover reduces glycolytic demand per stroke and improves aerobic contribution. Use tempo trainer — 6 × 50m building to 44 c/min.
🌊
Streamline work — reduce active drag Drag profile is above optimal for event. 10 min per session on underwater work: tight streamlines off every wall, 4–6 dolphins. A 2cm chin lift increases drag significantly.
💪
Power output: need 7.28 W/kg (currently 6.93 W/kg) +5% power delivers the projected target time. 2–3 hard sessions per week with full recovery between. Adaptation occurs in recovery — rest days are not optional.
