After 30 minutes of running, cardiac drift may cause your heart rate to increase so that you have to slow down to maintain that heart rate window of 160-170 bpm. When we sweat, a portion of the lost fluid volume comes from the plasma volume. Cardiovascular Drift. What environment is needed for cardiovascular drift to occur? During exercise aim for 750-1500 ml of water per hour, depending on the weight of the individual, intensity of exercise and the conditions. At the same time, vasoconstriction will occur at the non-essential organs, due to the limited supply of blood in the body. When exercising for long periods of time or in warm temperatures, an increased loss of fluids through sweat, expiration and muscle contraction occurs.
