 The study aimed to review the relationship between physical activity in healthy older adults and outcomes related to functional limitations, disability, or loss of independence. 66 studies were included that found greater aerobic physical activity was associated with higher functional status, while moderate to high levels of physical activity reduced the risk of functional limitations or disability. Exercise training interventions also improved physiological and functional measures, suggesting a long-term reduction in incidence of mobility disability. The study suggests that regular aerobic activity and short-term exercise programs can maintain functional independence in older age with moderate to higher levels of activity being effective. However, a precise characterization of an effective physical activity dose is difficult. This article was authored by Paterson Donald H and Warbert and Darren E. R.
