The 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 training attenuates the human respiratory muscle metaboreflex.
We hypothesized that inspiratory muscle training (IMT) would attenuate the sympathetically mediated heart rate (HR) and mean arterial pressure (MAP) increases normally observed during fatiguing inspiratory muscle work. An experimental group (Exp, n = 8) performed IMT 6 days per week for 5 weeks at 50% of maximal inspiratory pressure (MIP), while a control group (Sham, n = 8) performed IMT at 10...
متن کاملInspiratory Muscle Training During Treatment
In a previous study performed by us, functional alterations in the inspiratory muscles were evaluated in patients receiving corticosteroids for diseases other than respiratory. We have shown that patients who received high-dose steroids for several weeks developed inspiratory muscle weakness that was reversible following withdrawal of the drug treatment. The present study was designed to evalua...
متن کاملSpecificity and reversibility of inspiratory muscle training.
PURPOSE The purpose of this study was to evaluate the pressure-flow specificity of adaptations to inspiratory muscle training (IMT), in addition to the temporal effects of detraining and reduced frequency of training upon these adaptations. METHODS Twenty-four healthy subjects were assigned randomly to one of four groups (A: low-flow-high-pressure IMT; B: high-flow-low-pressure IMT; C: interm...
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 ...
