WebMore specifically, during aerobic exercise both heart rate and stroke volume increase to achieve a greater cardiac output. During resistance exercise, heart rate increases modestly but stroke volume decreases; thus cardiac output is only modestly increased. Myocardial Oxygen Consumption 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. WebWhat helps increase stroke volume during exercise?

WebConclusions: We conclude that there is an age-associated decline in heart rate, ejection fraction, and cardiac output responses to supine exercise in healthy men. Although the stroke volume responses of the young and old are similar, the old tend to augment stroke volume during exercise more through cardiac dilatation, with an increase in end ... WebDuring incremental exercise, stroke volume (SV) plateaus at 40-50% of maximal exercise capacity. In healthy individuals, left ventricular (LV) twist and untwisting ("LV twist mechanics") contribute to the generation of SV at rest, but whether the plateau in SV during incremental exercise is related to a blunting in LV twist mechanics remains unknown.
