A lack of blood at the skin decreases the sweating response, which in turn causes an increase in body temperature which if not lowered, in extreme cases can lead to heatstroke. Water is also important for many reactions within the cells including our metabolism, as well as helping us focus, concentrate and preventing low mood. Explain the term cardiovascular drift.

The muscular wall, dividing the heart into 2. Answer Booklet. The gradual time-dependent "drift" in several cardiovascular responses, most notably decreased stroke volume (with concomitant heart rate increase), during prolonged steady-rate exercise. Hydration in the body is carefully controlled as allowing too much or too little water into the cells can have significant consequences. If we drink too much and become hypohydrated (overhydrated), our kidneys increase filtration rates to deal with the increased blood pressure, subsequently, aldosterone levels decrease, resulting in more water being extracted from the blood and deposited through urination. A Level PE - AQA 3.1.1 Applied Anatomy & Physiology. eCollection 2022.

This website and its content is subject to our Terms and An increase in heart rate during exercise to compensate for a decrease in stroke volume. Reduced plasma volume, reduces venous return and stroke volume. 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. When core body temperature increases a similar increase is seen in heart rate. To understand the importance of fluid losses on cardiac drift researchers looked at cyclists who cycled for 2 hours either with or without taking on extra fluids during 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). From a body composition perspective, water is important in the metabolism of fats, as fats are only utilised in the muscle cells and for muscle cells to work they require water.
