Einfluss körperlicher Aktivität auf die menschliche Gesundheit

The lack of physical activity -- frequently associated with malnutrition -- has led to a dramatic increase of so-called diseases of civilization in industrial nations. Hereby -- apart from the cardiovascular diseases -- in particular disorders of carbohydrate and lipid metabolism as well as the musculoskeletal system are included. Physical inactivity can be considered a proven risk factor for these diseases. Children and adolescents are increasingly affected. In the development of effective preventive strategies, the enhancement of physical/sportive activities in everyday life as well as with in the framework of systematic health-orientated training plays a central role. This is confirmed by an abundance of scientific studies indicating that regular physical activity has anenormous potential with regard to the physical and psychological health maintenance in all life phases. The underlying biological mechanisms are complex and affect almost all human organic systems. Yet, the health benefit is critically dependent upon the form, duration and intensity. Endurance-orientated activities such as walking, running, cycling etc. performed at a moderate intensity, exercised at least 2 days a week for a duration of 30-60 min, are recommended. This should be supplemented by moderate strength training comprising all relevant muscle groups. An early commencement of regular, continuous, lifelong physical activities is particularly effective and can be, thus, recommended from a health-orientated perspective.
