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 .

Compared to static or dynamic resistance exercise, aerobic exercise demands an increase in energy and therefore an increase in oxygen (hence aerobic exercise). 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).

We recommend that you study the other three AQA Linear GCE PE courses and The Roadmap course along with this one. At the beginning of exercise there is a depression of the PNS and stimulation of the SNS, which causes a rapid increase in heart rate. Therefore, we must distribute blood to where it is needed most. 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.

Mechanisms: - Pocket valves - prevent backflow. The increase in cardiac output is due to an increase in both heart rate and stroke volume. Approximately how much fluid per hour exercise should someone consume? Vascular shunting is regulated by the sympathetic nervous system, which controls blood flow through vasodilation (opening of the arterioles, increasing flow of blood into the capillaries) and vasoconstriction (constricting of the arterioles, decreasing the flow of blood into the capillaries). Useful information to help you with the course. As shown in the below graphs heart rate then plateaus and is maintained at that level during lighter intensity exercise, whereas with higher intensity exercise heart rate plateaus after the initial increase and then gradually increases or drifts in an upwards direction. pptx, 3.84 MB.
