Summary:
Relationship of lung volume to ventilation during exercise in a) a healthy younger male; and b) an older male subject. There are greater volume constraints on tidal volume (VT) expansion (╦) during exercise in the older subject, i.e. increased residual volume (RV) and dynamic end-expiratory lung volume (EELV), and a relatively reduced inspiratory reserve volume (IRV; IRV = total lung capacity (TLC)−VT) at similar submaximal levels of ventilation. EILV: end-inspiratory lung volume; IC: inspiratory capacity; ERV: expiratory reserve volume; Vr: relaxation volume of the respiratory system; % pred: % predicted.
