Exercise Training Aerobic exercise benefits human health, particularly cardiovascular health.
Aerobic fitness can be assessed by measuring aerobic capacity - the ability of the body to take up and use oxygen during exercise. Parasympathetic control is, therefore, cardioprotective, and used as a direct index of the health of the heart. Long-duration endurance training reduces resting sympathetic control of the heart. Experimental findings on aerobic training-associated changes in baroreflex control have been inconsistent. Increased baroreflex sensitivity protects against potentially life-threatening arrhythmias.
