| dc.description.abstract | Fatigue can be affected by several sex-related factors and the purpose of this study was to investigate those differences associated with maximal-effort isotonic contractions of the plantar flexors. The criterion measure of fatigue here was reductions in instantaneous peak power. It was hypothesized that males would fatigue more than females and this was supported as peak power was reduced in males by 34% and by only 22% for females at the end of the fatigue task. Novel aspects of this study include the sex-based investigation of fatiguing isotonic plantar flexor contractions and the inclusion of rate of torque development and rate of velocity development as factors that may be contributing to the decreases in production of power during fatigue tasks. Overall, this study shows that males are more fatigable during dynamic contractions of the plantar flexors. | en_US |
