INTRODUCTION "Cardiovascular drift" (CV drift) is a phenomenon whereby some CV responses begin a continuous time-dependent change, or "drift," after 10 min of prolonged moderate-intensity exercise (e.g., 50-75% Vo 2 max) in a neutral or warm environment ().As displayed in Figure 1A, it is characterized by a progressive decline in stroke volume (SV) and pulmonary and systemic . During exercise, vasodilation of the arterioles supplying the working muscles, skin,and heart occurs, increasing the supply of oxygen and nutrients. More oxygen extraction by blood to the muscles, Venous blood has less O2 so the is more diffusion at the lungs. Respiration increases during exercise to meet the oxygen demand of the working muscles, resulting in a rise in water vapour loss through breathing, whilst sweat is lost in order to maintain body temperature. At the start of moderate-intensity aerobic exercise lasting over 30 minutes, cardiac output also increases, but to a higher level compared to lighter, submaximal exercise.
