Effect of Exercise on Cardiac Output Discussion 2. Discuss the effect of venous return and heart rate on exercise EDV. An increase in venous return of blood to the heart will result in greater filling of the ventricles during diastole. Consequently the volume of blood in the ventricles at the end of diastole, called end-diastolic volume, will be increased. A larger end-diastolic volume will stretch the heart. Stretching the muscles of the heart optimizes the length-strength relationship of the cardiac muscle fibers, resulting in stronger contractility and greater stroke volume.
