stroke volume
end-systolic volume
end-diastolic volume(EDV) the volume of blood in each ventricle at the end of diastole, usually about 120/130 mL but sometimes reaching 200/250 mL in the normal heart.end-systolic volume(ESV) the volume of blood remaining in each ventricle at the end of systole, usually about 50/60 mL but sometimes as little as10/30 mL in the normal
end-systolic volume
600 ml/min
Increasing end-diastolic volume (EDV) enhances stroke volume due to the Frank-Starling mechanism, where greater ventricular filling leads to stronger contractions. Higher end-systolic volume (ESV) can also increase stroke volume when it results from reduced afterload or increased contractility, allowing the heart to eject more blood with each beat. Thus, both EDV and ESV can influence stroke volume, primarily through changes in the heart's filling and pumping efficiency.
what difference does that make?? if it happens at the beginning it will end up being the end of your exercise!
The related value is called "stroke volume" and is equal to the end-diastolic volume minus the end-systolic volume, i.e. the maximum volume (pre-beat) less the minimum volume (post-beat). The typical volumes for the left ventricle are slightly smaller than those of the right ventricle, but the stroke volume may be slightly greater.
The word equation for stroke volume is the amount of blood pumped by the heart in one contraction. It is calculated by subtracting the amount of blood remaining in the ventricle after contraction (end-systolic volume) from the amount of blood in the ventricle just before contraction (end-diastolic volume).

70ml. It is just the difference. The stroke volume is the amount of blood pumped per contraction of the heart muscles (systole). End Diastolic Volume is the amount of blood in the heart just prior to contraction. End Systolic Volume is the amount of blood left in your heart after contraction.
