Medical Definition of Stroke volume - MedicineNet

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.
