dc.description.abstractWe examined the influence of operational lung volumes and mean inspiratory flow on the amplitude of the slow component of O2 uptake (?VO2SC ) during constant-load cycling performed below and above the respiratory compensation threshold (RCT) in young (24ᱠyr), healthy individuals (n = 10). Subjects demonstrated a significantly greater rise in expiratory reserve volume (ERV) and mean inspiratory flow over the ?VO2SC period during exercise performed above compared with below the RCT(P < 0.05). Inspiratory reserve volume (IRV) was, on average, smaller for trials performed above relative to below the RCT (P < 0.05). The difference in the magnitudes of change in ERV and mean inspiratory flow, but not IRV, were positively correlated with the increase in ?VO2SC amplitude between work rates (R2 = 0.86, P < 0.01). These findings suggest that dynamic hyperinflation and mean inspiratory flow (by increasing inspiratory resistive work) contribute to the development of the ?VO2SC , particularly when exercise is performed above the RCT.en_US
