With few exceptions, the lungs, airways and respiratory muscles of healthy humans are “overbuilt” for the ventilatory and gas-exchange demands imposed by exercise. This scenario may not apply during intense, sustained exercise during which three mechanisms primarily under the control of the respiratory system – namely, respiratory muscle work and fatigue, cyclical fluctuations in intrathoracic pressure, and arterial oxyhaemoglobin desaturation – are significant determinants of arterial oxygen content and/or blood flow and its distribution to the working legs. The aim of this webinar is to discuss these respiratory influences on oxygen transport and how they might exacerbate exercise-induced respiratory and/or peripheral muscle fatigue and compromise endurance performance in health and disease.
