The Effect of Exercise Intensity and Duration on Ventilation during Recovery from Moderate and Heavy Exercise
The results obtained from numerous experimental investigations suggest that the abrupt increase in ventilation (V-̇E) that is characteristic of phase 1 of constant load treadmill exercise is elicited by neural stimuli which originate from either exercising limb afferents or higher motor centers1, 2. Dejours and other investigators1, 2, 3 have proposed that these stimuli persist throughout exercise and combine in an additive fashion with humoral stimuli from the central and peripheral chemoreceptors, which may elicit the exponential increase in V-̇E that is characteristic of Phase 2, to control the steady state ventilatory response observed during Phase 3.
