Cam McEvoy's 50m freestyle world record (20.06s, Paris 2024) came after he dropped training volume from 30,000m/week to 8,000m/week — a 73% reduction. The core thesis: sprint swimming is nervous-system limited, not aerobic, so 99.9% of swimmers are burned out by traditional high-yardage methods that develop the wrong energy system. Strength reserve and neural freshness matter far more than lactate tolerance for heats, semis, and finals.
