What the study found

Longer sprints caused greater reductions in force and power and more peripheral fatigue than the work-matched shorter-sprint session. Voluntary activation declined similarly in both.

Participants and protocol

Eleven endurance-trained men completed both cycling protocols: eighteen five-second sprints and six twenty-second sprints. Muscle biopsies and neuromuscular tests tracked metabolic and fatigue responses.

What this cannot establish

An acute cycling experiment does not establish which programme produces better long-term fitness. Matching total work does not make two sessions equivalent in recovery cost.
