Although stroke volume can refer to either left or right side of the heart, it is most associated with the left side. when you repeatedly exerscise, the muscles around the heart increase in size and strength aswell as the space inside the heart increases.

Men, on average, have higher stroke volumes than women due to the larger size of their hearts. However, stroke volume depends on several factors such as heart size, contractility, duration of contraction, preload (end-diastolic volume), and afterload. Corresponding to the oxygen uptake, women's need for blood flow does not decrease and a higher cardiac frequency makes up for their smaller s…
