Cardiac Output: The cardiac output is simply the amount of blood pumped by the heart per minute.
Cardiac output is the amount of blood pumped by the heart in 1 min. This increases directly with increasing exercise intensity.
The heart rate increases from a resting rate of 72 beats/min to 150 beats/min or even more.
The stroke volume, meaning the amount of blood pumped into the Aorta with every heartbeat, increases from a resting volume of 70-90 mL to 100-120 mL per beat.
Exercise increases the plasma volume of blood by 12 Op:, but total blood volume may reduce slightly.
Blood flow is redistributed with more blood going to the muscles, heart and skin, while blood in the kidneys and abdomen is reduced.
Blood pressure increases due to exercise because there is more blood flowing in the blood vessels.
