Abstract

This study aimed to evaluate potential gender differences in recovery of power output during repeated all-out cycling exercise. Twenty men and thirteen women performed four series of two sprints (Sp1 and Sp2) of 8 s, separated by 15-, 30-, 60-, and 120-s recovery. Peak power (Ppeak), power at the 8th s, total mechanical work, and time to Ppeak were calculated for each sprint. Ppeak and mechanical work decreased significantly between Sp1 and Sp2 after 15-s recovery in both men (-6.4 and -9.4%, respectively) and women (-7.4 and -6.8%, respectively). Time to Ppeak did not change between recovery durations, but women reached their peak power more slowly than men (on average 5.15 ± 1.2 and 3.8 ± 1.2 s, respectively; P < 0.01). During Sp1 and Sp2, linear regressions from Ppeak to power at the 8th s showed a greater power decrease (%Ppeak) in women compared with men (P < 0.05). In conclusion, patterns of power output recovery between two consecutive short bouts were similar in men and women, despite lower overall performance and greater fatigability during sprints in women.
