Comorbidities affecting physical function increase with advanced-age and rural living. This study investigated the degree of benefit from resistance training (RT) in older adults based on age (50-89 years), location (urban vs. rural), and program duration (10 vs. 8-weeks). 260 participants completed pre- and post-program dynamic and static tasks and flexibility testing. Paired and independent -tests and one-way and repeated measures ANOVAs were used to test group improvements. All ages improved performance (all ≤ .002) but those in their 50's improved flexibility the most and those in their 60's improved 30STS more and tandem balance less than those in their 80's. Both rural and urban participants improved in all areas (all ≤ .002), but rural participants reported greater improvements in tandem balance. Both 10- and 8-week classes improved performance (all ≤ .001), but 8-week participants improved dynamic tasks and tandem balance more. RT can reduce functional discrepancies in older adults and rural residents.
影响身体功能的合并症会随着年龄增长和农村居住环境而增加。本研究基于年龄（50 - 89岁）、地点（城市与农村）和项目持续时间（10周与8周），调查了老年人进行抗阻训练（RT）的受益程度。260名参与者完成了项目前后的动态和静态任务以及柔韧性测试。使用配对和独立样本t检验以及单因素和重复测量方差分析来测试组间改善情况。所有年龄段的参与者表现均有改善（所有p值≤0.002），但50多岁的参与者柔韧性改善最大，60多岁的参与者在30秒坐站测试中的改善比80多岁的参与者更多，而在串联平衡方面的改善则较少。农村和城市参与者在所有方面均有改善（所有p值≤0.002），但农村参与者在串联平衡方面的改善更大。10周和8周的课程均能改善表现（所有p值≤0.001），但参加8周课程的参与者在动态任务和串联平衡方面的改善更大。抗阻训练可以减少老年人和农村居民的功能差异。
