Variations in endurance time across bodily regions may be readily explained by differences in muscle composition. Thus, it is not yet clear whether differential limb vascular response can potentially explain a portion of the regional fatigue sex differences observed between the elbow and the ankle. Few other muscle groups have been systematically studied for sex differences, but the limited evidence available suggests sex differences may not be readily predictable, as shoulder abduction was not different between men and women, whereas trunk flexion was more fatigue-resistant in females Sex differences in fatigue resistance are muscle group specific. Moore1 Maya N. No pain measures peak or rate of change resulted in significant correlations with endurance time.
Thus, these apparent sex differences between muscle groups could simply be due to cohort or methodological variance.

Accordingly, the effect sizes for the between-joint peak torque differences were large for males 3. The influence of age on isometric endurance and fatigue is muscle dependent: Effect of isometric exercise on pain perception and blood pressure in men and women. Footnotes This is a PDF file of an unedited manuscript that has been accepted for publication. Only the rate of exertion was significantly related to endurance time suggesting that nociceptive input was not a primary mechanism explaining the observed localized sex differences.
