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. Maximal oxygen uptake after attenuation of cardiovascular drift during heat stress. Water is vital for life and ensuring adequate hydration is important for both physical and mental well-being and performance. The progressive increase in heart rate with cardiovascular drift during exercise decreases end-diastolic volume and hence stroke volume. When exercising for long periods of time or in warm temperatures, an increased loss of fluids through sweat, expiration and muscle contraction occurs.
