During exercise, oxygen consumption and pulmonary ventilation increase dramatically, with breathing rate rising from 150 to over 500 breaths per minute. Cardiac output increases substantially as well, with stroke volume growing from 105 to 162 ml and heart rate increasing from 50 to over 185 beats per minute. These physiological changes maximize oxygen delivery and uptake throughout the body, enhancing performance and providing significant health benefits.
