Organizational and methodological aspects of health - related physical activity

Epidemiological studies over the past four decades have convincingly shown that physical inactivity and low physical fitness contribute substantially to the major chronic diseases prevalent in industrialized societies. Many scientific, medical and health organizations around the world have recognized formally the importance of regular physical activity (PA) as a means to promote and maintain health. Numerous statements on PA, based on solid scientific data, have been produced and made available. A summary of these can be found in Blair et al (1996)
