Description
Lauren Jutlah and co-authors rerun a sports science experiment on rest intervals in repeated sprinting. Their 2026 replication study belongs to an international project checking whether classic findings in the field hold up. The original study claimed that squeezing more work into each rest cycle raises oxygen use during the rests themselves.
Twenty-one young men performed ten maximal six-second cycling sprints with rests of twelve, eighteen, or twenty-four seconds. Oxygen use during both work and rest ran highest with the shortest rest, matching the original direction. The effect, though, came out smaller than first reported, a typical replication pattern. One difference did appear: oxygen during the sprints also varied, which the original had not found. The authors call the attempt a partial success that supports the claim with more honest effect sizes.
