Abstract

The distribution of work or energy expenditure throughout an exercise task may have a considerable influence on performance. However, the underlying mechanisms influencing an athlete’s pace during exercise are not well understood. During self-paced exercise in hot and humid environmental conditions power output is often down-regulated well before athletes reach critical core body temperatures. Clearly, numerous factors may influence this decrease in power output, including but not limited to, alterations in body temperature, energy metabolism, cardiovascular function and fluid balance. This manuscript briefly reviews factors that may influence the regulation of pace during prolonged high intensity exercise in the heat and the implications of such mechanisms on optimal pacing strategies.
