[BDSP. Notice produite par INIST eTR0xJ3i. Diffusion soumise à autorisation]. Leisure-time physical activity enhances health and functioning in older populations. However, few data are available on the correlation between self-reported leisure-time physical activity and cardiorespiratory fitness in the elderly. Treadmill exercise testing results were obtained for 1,006 members (median age 67 years) of a community-based sample. Subjects completed a standardized evaluation of medical/social history and measures of physical function. Leisure-time physical activity in the 12 months and 7 days before interview and over subjects'lifetimes was summarized as total and activity-specific METs/week and [METs * (hours/week) ]. Multiple linear regression was used to investigate the cross-sectional, sex-specific associations between peak oxygen consumption (VO2) and exercise duration. After adjustment for age, body mass index, smoking history, medical morbidity, direct measures of physical functioning, forced expiratory volumes, and maximum respiratory muscle pressure, leisure-time physical activity accounted for
