A 2024 scoping review on USRPT (which screened 90,613 studies) found that for 50–100m events the work-to-rest ratio should be 1:1 or 1:2, not the 1:3 or 1:4 ratios many coaches default to. Shorter rest keeps heart rate in the race-pace zone and trains the aerobic system to clear lactate between reps.
