Physical activity can prevent or delay the onset of physical functional limitations in older adults. There are limited data that evidence-based physical activity interventions can be successfully translated into community programs and result in similar benefits for physical functioning.
The purpose of this study is to measure the effects of the Active Living Every Day program on physical functioning and physical functional limitations in a diverse sample of older adults.
As a part of the Active for Life initiative, the Council on Aging of Southwestern Ohio implemented Active Living Every Day (ALED), a group-based lifestyle behavior change program designed to increase physical activity. Performance-based physical functioning tests (30-s Chair Stand Test, eight Foot Up-and-Go Test, Chair Sit-and-Reach Test, 30-Foot Walk Test) were administered to participants at baseline and posttest. Baseline to post-program changes in physical functioning and impairment status were examined with repeated measures analysis of covariance. Interactions tested whether change over time differed according to race/ethnicity, body mass index (BMI), and baseline impairment status.
Participants significantly increased their performance in all four physical functioning tests. The percentage of participants classified as "impaired" according to normative data significantly decreased over time. Physical functioning improved regardless of BMI, race/ethnicity, or baseline impairment status.
ALED is an example of an evidenced-based physical activity program that can be successfully translated into community programs and result in significant and clinically meaningful improvements in performance-based measures of physical functioning.
身体活动可以预防或延缓老年人身体功能受限的发生。目前数据有限，无法证明基于循证的身体活动干预措施可以成功转化为社区项目，并为身体功能带来类似的益处。
本研究旨在测量积极生活每一天（Active Living Every Day，ALED）计划对不同老年人样本身体功能和身体功能受限的影响。
作为积极生活倡议的一部分，俄亥俄州西南部老年人理事会实施了积极生活每一天（ALED），这是一个基于小组的生活方式行为改变计划，旨在增加身体活动。在基线和后测时，对参与者进行基于表现的身体功能测试（30 秒椅子站立测试、8 英尺上和走测试、椅子坐和伸展测试、30 英尺步行测试）。使用重复测量协方差分析检验身体功能和损伤状态的基线到后测变化。交互作用检验了随着时间的推移，变化是否根据种族/民族、体重指数（BMI）和基线损伤状态而有所不同。
参与者在所有四项身体功能测试中的表现均显著提高。根据参考数据，被归类为“受损”的参与者比例随着时间的推移显著下降。无论 BMI、种族/民族或基线损伤状态如何，身体功能都有所改善。
ALED 是一个基于循证的身体活动计划的例子，它可以成功转化为社区项目，并在基于表现的身体功能测量方面带来显著且具有临床意义的改善。
