成功老龄化研究的一个主要目标是确定与较高身体功能的可塑性相关的可改变因素;然而，人们对习惯性身体活动（特别是低强度至中等强度的活动）与老年人日常功能维持之间的关系知之甚少。本文的目的是要解决的问题，身体活动的模式如何转化为改变身体功能的健康老年人群。在本文中，身体活动被归类为一种行为，而身体功能被归类为性能，由一系列日益整合的步骤组成。最近几项流行病学研究的数据表明，身体活动与维持身体功能的更基本组成部分有关，也与健康老年人的高阶任务或目标导向功能有关。此外，更高水平的身体活动似乎与更好的功能有关，即使是那些已经患有慢性疾病的人。最近的CDC/ACSM健康建议要求将至少30分钟的任何活动纳入日常计划。因此，应鼓励一般老年人定期参加中等强度的活动（如散步、园艺、家务/庭院劳动）。
A primary goal of studies of successful aging is to identify the modifiable factors related to the plasticity of higher physical function; however, little is known about the relationship between habitual physical activity (especially that of lower- to moderate-intensity) and the maintenance of day-re-day functioning in older people. The purpose of this paper is to address the question of how patterns of physical activity translate into altered physical function among healthy older populations. In this paper, physical activity is classified as a behavior, whereas physical function is classified as performance, comprised of a series of increasingly integrated steps. Recent data from several epidemiologic studies suggest that physical activity is associated with the maintenance of more basic components of physical function, as well as with higher-order task or goal-oriented functions in healthy older people. Moreover, higher levels of physical activity appear to be associated with better functioning, even in those with already-existing chronic disease. Recent CDC/ACSM health recommendations call for incorporating at least 30 min of any activity into the daily schedule. Therefore, regular participation in activities of moderate intensity (such as walking, gardening, house/yard work) should be encouraged among the general older community.
