title: [Specific risks of physical activity in the elderly].
abstract: The aim of this paper is to present the specific risks of physical activity in elderly subjects. These risks mainly consist of the loss of physical integrity and the weakening of the capabilities of metabolic regulation. The risk of impairment of physical integrity (e.g. injury) related to regular physical activity is not overall greater in elderly subjects than in young subjects. The choice of a physical activity that is suited to the elderly subject's physical and cognitive abilities largely limits these risks. When physical activity is adapted to suit elderly subjects, the number of accidents in relation to the number of participants is actually very low. In fact, participation in a program of education for prevention related to physical activity reduces the risk of accidents and injuries (and, thus, falls) occurring thereafter. In the case of metabolic risks, isometric muscular contractions carried out under certain conditions (duration: > 6 seconds; intensity: > 50% of maximal voluntary contraction) are inappropriate. Physical activity carried out in extreme thermal atmospheres (0-5° < and > 25-30°) should be avoided. Hydration is very important and liquids should be drunk well before any thirst sensation occurs.
