Results of a systematic review of the inverse dose-response relationship between volume of aerobic physical activity and risk of physical functional limitations in the general aging population. Categories of physical activity level were derived from prospective cohort studies with covariate adjustment: 0)=no activity; 1) = light activities only occasion walking or gardening; 2) = moderate level of activity (volume = 3-5 days/week for 30 min/day; and 3) = vigorous activities and/or high volume of systematic activity. The odds ratio is the odds of disability in the physical activity group relative to a comparison group. ADL=activities of daily living; IADL=instrumental activities of daily living; QOL=quality of life score. Figure reproduced with permission from Paterson & Warburton, 2010.
