WebDuring dynamic exercise, the force resisting ejection in the periphery (total peripheral resistance) is reduced by vasodilation, owing to the effect of local metabolites on the skeletal muscle vasculature. Thus, despite even a fivefold increase in cardiac output among normal subjects during exercise, mean arterial pressure increases only ... WebCardiac output = stroke volume × heart rate. Your stroke volume is the amount of blood your heart pumps each time it beats, and your heart rate is the number of times your heart beats per minute. During exercise, your body may need three or four times your normal cardiac output, because your muscles need more oxygen when you exert yourself.

WebJun 18, 2024 · Dr. Tracy Lawrence answered. 23 years experience. Increases workload: Hypertension causes the central aortic blood pressure to increase. Going back to physics: flow ( cardiac output) = pressure gradient (pressure the heart generates- blood pressure) / resistance of the vessels.
