How does stroke volume increase with exercise
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. WebThe relationships between exercise intensity and 1) stroke volume, 2) end-systolic volume, and 3) end-diastolic volume are different when exercise is per-formed in the supine posture versus exercise in the upright posture, as illustrated in Fig. 3. These differ-ences are largely the result of the effects of the force of gravity on venous return.
