Abstract: OBJECTIVE: This study examined the effects of %sex gender on peak
torque (PT), average power (AP), and the time (AMP) and frequency (MPF) domain
parameters of the electromyographic (EMG) and mechanomyographic (MMG) signals
following very short-term resistance training (VST) of the forearm flexors.
Based on the results of previous studies it was hypothesized that three
training sessions would increase PT, EMG MPF, and MMG MPF of the forearm
flexors at 60 and 180°/s in men only, without changes to AP, EMG AMP, or
MMG AMP for either men or women. METHODS: Nine men and nine women completed two pretests, three
training sessions, and a posttest that included concentric isokinetic muscle
actions of the forearm flexors at 60 and 180°/s. The AMP and MPF of the EMG
and MMG signals were recorded from the biceps brachii. RESULTS: The results indicate increases in PT, AP, and MMG AMP at 60
and 180°/s for the men only, but no changes in EMG AMP, EMG MPF, or MMG MPF
for either the men or women. CONCLUSION: There were gender differences in the PT and AP responses
to VST of the forearm flexors that were not associated with increased agonist
muscle activation. These findings have implications for the development of
gender-specific VST programs for the forearm flexors in clinical settings.
