One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16]. The amount of blood pumped out during systole is called the stroke volume and is less than the end diastolic volume because the ventricles do not completely empty themselves during systole. At all levels of physical activity stroke volume is increased. There is an improvement in ventricular performance with an increase of plasma volume [4] and a faster peak lengthening the rate of the left ventricle during diastole [6].
