title: Can physical activity counteract ageing?
abstract: The normal process of ageing in human leads to gradual impairment of function in most organs, including the locomotor system. Physical activity can to a certain extent counteract this. In addition a favourable influence on symptoms of ageing can be seen. Although persons with a life-long history of optimal physical activity often reach a high age, there is no definite proof that this activity can significantly increase the mean life span. The greatest relative effect of physical training is obtained in those who have been least fit. A high level of physical activity in youth does not imply better fitness in old age unless the person has trained continuously. Even in old age physical training can have a favourable effect, giving increased motility, better muscular strength and endurance as well as a higher maximal aerobic power. The main effects are better bodily fitness, better function in daily living, and increased social contact.
