Ind Health. Cardiovascular drift, the progressive increase in heart rate and decrease in stroke volume that begins after approximately 10 min of prolonged moderate-intensity exercise, is associated with decreased maximal oxygen uptake, particularly during heat stress. At the same time, vasoconstriction will occur at the non-essential organs, due to the limited supply of blood in the body.
