Prolonged Intermittent Running Induces Inspiratory-Muscle Fatigue in Female Runners
Inspiratory-muscle fatigue (IMF) may occur after long-duration or continuous short-duration exercise and may limit exercise performance. Daily athletics training is often intermittent, but it is unclear if intermittent running induces IMF. We investigated IMF after a maximal anaerobic running test (MART) and maximal intermittent graded exercise test. Nine female middle-distance (400 or 800 m) r...
متن کاملThe influence of inspiratory muscle work history and specific inspiratory muscle training upon human limb muscle fatigue.
The purpose of this study was to assess the influence of the work history of the inspiratory muscles upon the fatigue characteristics of the plantar flexors (PF). We hypothesized that under conditions where the inspiratory muscle metaboreflex has been elicited, PF fatigue would be hastened due to peripheral vasoconstriction. Eight volunteers undertook seven test conditions, two of which followe...
متن کاملInspiratory muscle fatigue following moderate-intensity exercise in the heat.
Heavy exercise has been shown to elicit reductions in inspiratory muscle strength in healthy subjects. Our purpose was to determine the combined effects of moderate-intensity endurance exercise and a thermal load on inspiratory muscle strength in active subjects. Eight active, non heat-acclimatized female subjects (23.5 ± 1.4 yr; VO2max = 39.8 ± 2.4 ml.kg(-1).min(-1)) randomly performed two 40 ...
متن کاملInspiratory muscle work in acute hypoxia influences locomotor muscle fatigue and exercise performance of healthy humans.
Our aim was to isolate the independent effects of 1) inspiratory muscle work (W(b)) and 2) arterial hypoxemia during heavy-intensity exercise in acute hypoxia on locomotor muscle fatigue. Eight cyclists exercised to exhaustion in hypoxia [inspired O(2) fraction (Fi(O(2))) = 0.15, arterial hemoglobin saturation (Sa(O(2))) = 81 +/- 1%; 8.6 +/- 0.5 min, 273 +/- 6 W; Hypoxia-control (Ctrl)] and at ...
متن کاملInspiratory muscle fatigue increases sympathetic vasomotor outflow and blood pressure during submaximal exercise.
The purpose of this study was to elucidate the influence of inspiratory muscle fatigue on muscle sympathetic nerve activity (MSNA) and blood pressure (BP) response during submaximal exercise. We hypothesized that inspiratory muscle fatigue would elicit increases in sympathetic vasoconstrictor outflow and BP during dynamic leg exercise. The subjects carried out four submaximal exercise tests: tw...
