How does stroke volume change with exercise
WebDuring exercise, the cardiac output increases more than the total resistance decreases, so the mean arterial pressure usually increases by a small amount. Pulse pressure, in … WebSometimes, like when you’re exercising, your body needs more oxygen. At that time, your body can change its cardiac output by adjusting your heart rate and stroke volume. Blood delivers oxygen to your cells, so you need more cardiac output when your active body is using more oxygen than usual.
