Effect of expiratory muscle fatigue on exercise tolerance and locomotor muscle fatigue in healthy humans.
High-intensity exercise (> or =90% of maximal O(2) uptake) sustained to the limit of tolerance elicits expiratory muscle fatigue (EMF). We asked whether prior EMF affects subsequent exercise tolerance. Eight male subjects (means +/- SD; maximal O(2) uptake = 53.5 +/- 5.2 ml.kg(-1).min(-1)) cycled at 90% of peak power output to the limit of tolerance with (EMF-EX) and without (CON-EX) prior indu...
متن کاملExercise-induced respiratory muscle fatigue: implications for performance.
It is commonly held that the respiratory system has ample capacity relative to the demand for maximal O(2) and CO(2) transport in healthy humans exercising near sea level. However, this situation may not apply during heavy-intensity, sustained exercise where exercise may encroach on the capacity of the respiratory system. Nerve stimulation techniques have provided objective evidence that the di...
متن کاملEffect of Expiratory Muscle Fatigue on the Respiratory Response during Exercise
[PURPOSE] THE AIM OF THIS STUDY WAS TO REVEAL THE EFFECT OF EXPIRATORY MUSCLE FATIGUE (EMF) ON RESPIRATORY RESPONSE UNDER TWO DIFFERENT EXERCISE CONDITIONS: exercise (EX) with EMF (EMF-EX) and control EX without EMF (CON-EX). [Methods] Nine healthy adult men performed cycle exercise with a ramp load, and a spirometer was used to measure forced vital capacity (FVC), forced expiratory volume in o...

متن کاملExpiratory muscle fatigue does not regulate operating lung volumes during high-intensity exercise in healthy humans.
To determine whether expiratory muscle fatigue (EMF) is involved in regulating operating lung volumes during exercise, nine recreationally active subjects cycled at 90% of peak work rate to the limit of tolerance with prior induction of EMF (EMF-ex) and for a time equal to that achieved in EMF-ex without prior induction of EMF (ISO-ex). EMF was assessed by measuring changes in magnetically evok...
