Stroke volume increases during exercise because the body's demand for more oxygen-filled blood increases, and an increase in stroke volume, due to contractions that are more powerful, will help eject...
Stroke volume is the amount of blood that is sent out of the heart during the systole stroke of the heartbeat. This is the combined output of both the left and the right ventricles. For a healthy male, this volume is somewhere around 5.6 liters per hour, for a healthy female, 4.9 liters per hour. The factors that could affect stroke volume would be heart disease, any of which narrow the ventricles chambers. Some of these diseases weaken the muscle of the ventricles, causing a decreased heart rate. Atherosclerosis, or hardening of the arteries, can have a dibilitating effect on cardiac output as well.
