Temperature regulation and hyperthermia during exercise.

This article first describes the physical aspects of heat transfer from skeletal muscles to the environment during exercise, emphasizing environmental factors that affect these transfers. Next, the characteristics of the human thermoregulatory mechanism are described, illustrating the ability to modify rates of heat transfer over a wide range in response to changes in the body temperatures. Finally, problems that develop during exercise in the heat are described, and practical information for minimizing such problems is given.
