AUTONOMIC NERVOUS SYSTEM REGULATION of the heart and vasculature plays a key role in enabling the tight coupling between oxygen consumption of exercising skeletal muscles and oxygen delivery. The withdrawal of cardiac parasympathetic nerve activity and elevation in cardiac sympathetic nerve activity facilitate the exercise intensity-dependent increase in heart rate, ventricular contractility, stroke volume, and cardiac output (5). Robinson et al. (10) laid the foundations for the present… CONTINUE READING
