Fig. 4. The time course of fatigue is shown for the three muscles (FCR, AIL, ECU)
over 4 min. Force was averaged in 30 s intervals and expressed as a percentage
of the maximal mean force. In both FCR and AIL, forces declined more
significantly (indicated by asterisks) in females than in males
(P<0.05, adjusted with sequential Bonferroni; k=8).
Values are means ± s.e.m.
