The entries use clear definitions, examples, and suggestions for further reading to explore each discipline.



Why Should a Sports and Exercise Scientist Be Interested in Homeostasis?

Three of the major homeostatic mechanisms that are particularly relevant to sport and exercise are: thermoregulation, osmoregulation and regulation of blood glucose levels.

Humans require a stable internal environment to function effectively. The maintenance of this internal environment within tolerable limits is called homeostasis. Humans survive in their natural external environment based on the physiology of their internal environment. Homeostasis is a dynamic process, with continual monitoring of the body's biochemical and physical status. The nervous and endocrine body organ systems provide control and regulation of the body's internal biochemical and physical environments.
