heart pumps more blood per heartbeat, resting heart rate slows, blood volume increases, body can cool itself better, resting blood pressure decrease, metabolism in skeletal muscle enhanced (improved fuel use), increased antioxidant chemicals in body and lowers oxidative stress. muscular strength helps:
