During exercise, end systolic volume (ESV) typically decreases. This is because the heart contracts more forcefully and efficiently, leading to a greater stroke volume and more complete emptying of the ventricles. As a result, the heart expels more blood with each beat, reducing the volume of blood remaining in the ventricles after systole. Consequently, ESV can decrease, contributing to improved cardiac output during physical activity.
