Physical exercise activates the sympathetic nervous system and thus puts the whole body on the alert, increases muscle activities which is very obvious, increases the cardiac activity and cardiac output, increases oxygen supply and there are physiological adaptations which make more oxygen available to the muscles and also greater extraction of oxygen at the peripheral level.
