During maximal intensity leg cycling sprints, previous research has shown that central and peripheral fatigue development occurs with various (<30 s) short-duration recovery periods between sprints. The aim of the current study was to compare the development of neuromuscular fatigue during maximal intensity lower-body sprints interspersed with short and longer duration recovery periods.

Crossover study.

Ten participants completed 10, 10 s sprints interspersed with either 30 or 180 s of recovery. Peak power outputs were measured for each sprint. Maximal force, voluntary activation (VA) and evoked contractile properties of the knee extensors were measured at pre-sprint 1, post-sprint 5 and post-sprint 10. Perceived pain was also measured immediately following each sprint.

Peak power output was significantly lower by 16.1 ± 4.2% (p < 0.001) during sprint 10 with 30 compared to …
