Vascular shunting is regulated by the sympathetic nervous system, which controls blood flow through vasodilation (opening of the arterioles, increasing flow of blood into the capillaries) and vasoconstriction (constricting of the arterioles, decreasing the flow of blood into the capillaries). Cardiac output can be expressed by the below formula: Cardiac output = stroke volume (SV) X heart rate (HR). Consequently, the increased heart rate reflects an increased relative metabolic intensity during prolonged exercise in the heat when cardiovascular drift occurs, which has implications for exercise prescription. Arterio-venous oxygen . Bookshelf This results in a decrease in pulmonary arterial pressure and reduced stroke volume.
