The starting hypothesis is aimed at the retarding effect of sporting activities on ageing. Sport just improve those abilities, which are reduced with ageing, for instance the motoric-dynamic mobilities. The effect of sport can also be identified at the heart-circuit-respiration-system. Staying power training is desired for preventive effectiveness. Psychic functions are influenced and models of behaviour are formed by sport. Individual motivations must be used stronger and barriers must be destroyed to increase the general efficaciousness of sports in old age. Sport in old age is not identical with sport of pensioners, the health training should already start in the fourties and continued up to the end of the life. Concerning the organisation and fitness of the persons the lawfulness has to be considered.
