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. 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 . Define cardiovascular drift A This is where your heart rate slowly increases after 10 minutes of steady exercise in a warm environment. a moderate level of intensity is between 40% and 59% of heart rate reserve or oxygen consumption reserve. A reduction in hydration results in a decrease in blood volume and pressure, which results in cells becoming more concentrated and the kidneys not functioning effectively (decreased filtration).
