Sports Coach :: Climate control: acclimatising to the heat Author: Lisa Yates, Sports Dietitian, The Coaches Edge Issue:Volume 27 Number 1 Exercising in hot, humid conditions when the body is not accustomed to it can place the body under great stress. The demand for circulation to working muscles, which are producing heat, overtakes the need for blood flow to the skin to transport heat away from the body. As a result, body temperature rises. What is heat acclimatisation? The benefits of heat acclimatisation have been known for many years (Robinson 1967). What are the benefits of being heat acclimatised? Acclimatisation produces: a lower heart rate at a given heat and exercise stress level better maintenance of core body temperature reduction in the sweating threshold increased distribution of active sweat glands increased sweat rate an increased sweating sensitivity to increasing core body temperature a reduction in the loss of water and electrolytes from the kidneys (Robinson 1967).
