Therefore the main factors impacted in chronic adaptation to exercise are blood flow, and oxygen extraction in the tissues. Why can prolonged stress result in cardiovascular disease? If vital capacity expands, your total lung capacity does as well, as you can take fuller, deeper and more oxygen-rich breaths. Inspiratory capacity increased with exercise because of the greater amount of air that could be moved, due to greater tidal volumes. What does it mean that the Bible was divinely inspired?
