Résumé :	[BDSP. Notice produite par INIST zfyYR0xf. Diffusion soumise à autorisation]. Physical activity is associated with better health ; however, the optimal intensity of activity remains unclear. A total of 13,485 men (mean age, 57.5 years) from the Harvard Alumni Health Study reported their walking, stair climbing, and sports/recreation in 1977. Between 1977 and 1992,2,539 died. After adjusting for the different activity components, distance walked and storeys climbed independently predicted longevity (p, trend=0.004 and<0.001, respectively). Light activities (<4 multiples of resting metabolic rate (METs)) were not associated with reduced mortality rates, moderate activities (4-<6 METs) appeared somewhat beneficial, and vigorous activities (>=6 METs) clearly predicted lower mortality rates (p, trend=0.72,0.07, and<0.001, respectively). These data provide some support for current recommendations that emphasize moderate intensity activity ; they also clearly indicate a benefit of vigorous activity.
