N2 - Previous studies have reported women to have a greater resistance
to fatigue than men during sustained handgrip exercise,
however, observed gender differences in fatigue has been shown
to be a function of contraction type. The purpose of the present
study was to determine if gender differences exist in forearm
muscle fatigue during intermittent handgrip contractions.
Women [n = 11, 23.5 ± 1.5 (SE) yr] and men (n = 11, 24.1 ± 1.5
yr) performed intermittent isometric handgrip contractions at a
target force of 50% of maximal voluntary contraction (MVC)
for 5 s followed by 5 s rest until task failure. Rate of fatigue was
calculated from MVCs taken every 2 min during exercise, and
recovery of muscle strength was measured in 5 min increments
until 45 min post-task failure. Forearm muscle strength was less
for women than men (W: 341.5 ± 11.9 N; M: 480.2 ± 28.0 N; p
≤ 0.05). No gender difference was present in time to task failure
(W: 793.3 ± 92.5 s; M: 684.8 ± 76.3 s) or in the decrease in
m
