During exercise, (increases/decreases) _______________ in the partial pressure of carbon dioxide and (increases/decreases) _______________ in the pH of the blood cause the central and peripheral chemoreceptors to send (afferent/efferent) nerve signals to the respiratory control center of the brain.
The aerobic capacity (VO2 max) (increases/decreases) _________________ with increases in altitude. Thus, any submaximal work represents a (greater/lesser)________________percentage of oneâs total capacity. In other words, a given submaximal work level requires the same metabolic adaptations that would otherwise occur during exercise at a (higher/lower) __________%VO2max that is performed at sea-level.
The a-vO2 difference is (minimized/maximized) _________________during maximal intensity exercise because arterial oxygen extraction (unloading) is (increased/decreased) _________________ at the skeletal muscle capillary beds to meet the match the (increased/decreased) _________________ demand for oxygen to act as a final electron acceptor in the oxidative synthesis of ATP.
