[Sport as a means to prevention, rehabilitation, and health promotion. An expert opinion].

Physical activities are particularly health effective when they are structured and systematically organized, for example, with respect to a dose-response relationship or to psychosocial aspects. Which insights can be gained from scientific knowledge on the structure of physical activities? Which health-related goals can be sought with different physical activities in the field of sport? Which target groups can be reached with these kinds of sport? These questions are addressed in this article on the basis of current scientific knowledge-to promote the development of health-enhancing physical activities especially in sport federations, but also to create a communication platform between the sport and the health sector. The work of researchers in this field is focused mainly on health-enhancing physical activity, but they are also engaged in health-related scientific organizations and in sport federations.
