Throughout the day, we lose approximately 700 ml of water during expiration when breathing, 1.5 litres through urination and up to 150-200 ml as sweat whilst exercising. When exercising for long periods of time or in warm temperatures, an increased loss of fluids through sweat, expiration and muscle contraction occurs. Cardiovascular drift. The best way to prevent dehydration is by regularly taking on fluid throughout your training or competition. Define cardiovascular drift A This is where your heart rate slowly increases after 10 minutes of steady exercise in a warm environment.

These figures will increase further if exercising intensely, particularly during endurance-based exercise or when exercising in warm temperatures. Venous Return The following are common symptoms: Cardiovascular drift refers to an increase in heart rate during prolonged endurance-based exercise, despite working at a constant intensity. The increase in skin blood flow occurs at the same time that the working muscles demand a large proportion of blood flow, which creates competition and demand from different parts of the body. Contact PE Dept. Cardiovascular drift has been debated for a long time.

The rise in cardiac output is a result of a rise in heart rate and stroke volume and the subsequent plateau is a result of an appropriate supply of oxygen to sustain the metabolic demands of the physical activity. When we sweat, a portion of the lost fluid volume comes from the plasma volume. 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).
