Suggested reading list for those aiming for higher grades. What T is the process of maintaining an internal temperature within a tolerable range, These specialised cells detect changes in temperature, What D is known as a serious reduction in the body's water content, What H is known as the amount of water vapor in the air, What H is known as abnormally high body temperature, What H is known as abnormally low body temperature, An increase in heart rate during exercise to compensate for a decrease in stroke volume. Prolonged exercise induces cardiovascular drift, which is characterized by decreasing mean arterial pressure (MAP), stroke volume and heart rate increase. The progressive increase in heart rate with cardiovascular drift during exercise decreases end-diastolic volume and hence stroke volume. 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.

Registered office: International House, Queens Road, Brighton, BN1 3XE. Interval-induced metabolic perturbation determines tissue fluid shifts into skeletal muscle. 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. More energy is needed to cool body/sweat. This website and its content is subject to our Terms and Venous Return. Furthermore, when core body temperature increases the body responds by increasing skin blood flow to help control the temperature rise. The gradual upward drift of heart rate is matched by a comparative reduction in stroke volume, which enables cardiac output to be preserved. Your rating is required to reflect your happiness.

Stroke volume increases rapidly during the rst minutes of exercise and plateaus at a maxi-mal level after a workload of approximately 40-50% of VO 2max has been achieved (P. strand, et al., 3 marks Answer: Cardiovascular drift is characterised by a decrease in stroke volume and a parallel increase in heart rate to maintain a constant cardiac output. The number of heart beats per unit of time, usually per minute. 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.
