WebCardiac output = stroke volume x heart rate (CO= SV X HR) An increase in heart rate, stroke volume, or both will increase the cardiac output, which mainly happens during exercises. Heart Rate (HR) This is the number of times a person’s heart beats per minute. Webcrease in both stroke volume and heart rate. Stroke volume exhibits a pattern of initial in-crease, plateaus, and then displays a negative (down-ward) drift. Stroke volume increases rapidly during the ﬁrst minutes of exercise and plateaus at a maxi-mal level after a workload of approximately 40–50% of VO 2max has been achieved (P. Åstrand ... WebDec 18, 2024 · Initially, cardiac output increases due to an increase in your heart rate. Then, as your aerobic fitness improves, cardiac output increases due to an increase in stroke volume and a decrease in heart rate.

During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps. What increases the stroke volume?
