Comparative StudyGender differences in the fatigability of the inspiratory muscles.
The purpose of the present study was to determine whether gender differences are present in the fatigability of the inspiratory muscles of humans. Based on evidence for a gender difference in the oxygen cost of breathing, we hypothesized that females would result in a greater magnitude and/or faster rate of inspiratory muscle fatigue than males. ⋯ The results provide some evidence that the fatigability of the inspiratory muscles is different between genders. Females demonstrated a slower rate of fatigue during resistive breathing than males, a finding independent of muscle strength.
