From a body composition perspective, water is important in the metabolism of fats, as fats are only utilised in the muscle cells and for muscle cells to work they require water. If we drink too much and become hypohydrated (overhydrated), our kidneys increase filtration rates to deal with the increased blood pressure, subsequently, aldosterone levels decrease, resulting in more water being extracted from the blood and deposited through urination. Increase in heart rate due to/and a decrease in stroke volume / ejection fraction B.

The presence of electrolytes in sports drinks replaces those lost in sweat and also helps to abolish the risk of developing hyponatremia. [citation needed] It is characterized by decreases in mean arterial pressure and stroke volume and a parallel increase in heart rate. What causes cardiovascular drift? What increases during cardiovascular drift? 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). Is the transport of blood back to heart.
