本文主要回顧近年來相關實證性研究報告結果來探討體能活動對於老年人認知功能的影響效益。藉由提供社區老年人預防性的體能活動建議以及給予臨床或長期照護機構中認知功能異常衰弱老年人治療性的體能活動，來促進健康老化及改善（或延緩）老年人認知功能衰退的目標，同時也提出相關效益的可能機制和研究的限制及未來可行方向。

This article reviews recent experimental researches to investigate the benefits of physical activity on cognitive function of elderly adults. We provide preventive and therapeutic physical activities for healthy community-dwelling elderly and frail elderly with cognitive impairment in clinics or long-term care institutions to achieve the goal in promoting healthy aging and improving/retarding cognitive function decline.
