Increase in stroke volume during exercise

WebDuring exercise, the heart rate increases and the force of contraction of the ventricles increases, therefore cardiac output and stroke volume increase. previous 1 WebThe ventricular muscles also contract more strongly, which reduces the volume inside the ventricles and increases the stroke volume. Increases in stroke volume and heart rate will increase cardiac output. The sympathetic nervous system also causes vasoconstriction (arterioles constrict), increasing peripheral resistance. This seems counterintuitive, …
