Figure 2.
Individual (circles) and group mean (−) data showing the changes in (A) time to exhaustion, (B) maximal voluntary contraction (MVC), (C) potentiated twitch force (Qtw,pot), and (D) voluntary muscle activation (VA) under control condition (No-PreF, ○) and under experimental condition (PreF, ●, i.e., exercise performed with prior fatigue induced by electrical stimulation in the contralateral leg). *Significantly different from No-PreF (ANOVA, condition × time interaction, P < 0.05); Number of participants (n) = 8. No-PreF, nonprefatigued condition; PreF, prefatigued condition.
