How does exercise affect stroke volume

WebSep 12, 2024 · The definition of stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction. The average stroke volume of a 70 kg male is 70 mL Not all of the blood that fills the heart by the end of diastole (end-diastolic volume - EDV) can be ejected from the heart during systole. WebDuring moderate, upright, whole body exercise (e.g., running, bicycling) increased venous return to the heart by the muscle and respiratory pump systems may cause a small increase in end-diastolic volume (shown in figure); however, if heart rate increases to very high rates, reduced diastolic filling time can reduce end-diastolic volume.

WebJun 19, 2013 · Stroke Volume (SV) is the volume of blood in millilitres ejected from the each ventricle due to the contraction of the heart muscle which compresses these ventricles. SV is the difference between end diastolic volume (EDV) and end systolic volume (ESV). Multiple factors can affect SV, eg. factors that change either EDV or ESV will change SV. 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.
