 The study aims to investigate the relationship between physical activity in healthy community dwelling older adults and outcomes related to functional limitations, disability, or loss of independence. The study found that greater physical activity of an aerobic nature was associated with higher functional status, while moderate and high levels of physical activity were effective in reducing the risk of functional limitations or disability. Exercise training interventions also showed improvement in 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 may be effective in maintaining 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 Patterson Donald H. and Warburton Darren E.R.
