Aktywność fizyczna a zdrowie

„Physical activity is a key and a integral factor of healthy life style. It is impossible to plan health strategy without it or its development or maintenance and amongst children – correct growth. Lack of physical activity is the main and autonomous risk factor of vascular diseases” (Drabik 1996, s. 215). At this point it becomes important to acknowledge the definition of homeostasis put forward by W. Cannon (1932) in the thirties. This definition mostly refers to autoregulation of biological processes. In general it stands for internal and external balance of human body that can be changed by physical exercises.
