During exercise, the body requires more oxygen and nutrients to fuel the muscles. Vasodilation helps to increase blood flow and oxygen delivery to the muscles, allowing them to work harder and longer. Vasoconstriction, on the other hand, would decrease blood flow and limit the amount of oxygen and nutrients reaching the muscles, leading to fatigue and decreased performance. Increased respiratory rate also helps to get more oxygen to the muscles, but it is not directly related to blood supply.
