Cardiovascular Dynamics during Exercise
McArdle, Katch and Katch, 4th ed.
Cardiac Output (Q): amount of blood pumped per minute.
Stroke Volume: amount of blood pumped each cardiac cycle.
Left Ventricular End Diastolic Volume
Left Ventricular End Systolic Volume
SV increases due to
Shunting of blood via constricting arterioles and closing precapillary sphincters.
