BACKGROUND
Strength training (ST) is an important health behavior for aging women; it helps maintain strength and function and reduces risk for chronic diseases. This study assessed change in physical fitness following participation in a ST program implemented and evaluated by community leaders.
METHOD
The StrongWomen Program is a nationally disseminated, research-based, community ST program active in 40 states. The Senior Fitness Test is used to assess upper and lower body strength, upper and lower body flexibility, aerobic fitness, and agility; data are collected prior to and following program participation.
RESULTS
For these analyses, five states provided deidentified data for 367 female participants, mean age 63 (±11) years. Attendance in approximately 10 weeks of twice-weekly classes was 69.4%. Paired t tests were used to analyze pre-post change. Significant improvements were observed (p < .01) in all Senior Fitness Test measures. Data are stratified by age-group and compared with published, age-based norms.
CONCLUSIONS
This study demonstrates that it is feasible for community leaders to conduct pre-post physical fitness evaluations with participants and that participants experienced improvements across several important domains of physical fitness.
背景
力量训练（ST）是老年女性的重要健康行为；它有助于维持力量和功能，降低慢性病的风险。本研究评估了参与由社区领袖实施和评估的 ST 计划后身体适应性的变化。
方法
StrongWomen 计划是一个全国性传播的、基于研究的、社区性的力量训练计划，在 40 个州开展活动。高级体能测试用于评估上下肢力量、上下肢柔韧性、有氧健身和敏捷性；在参与项目之前和之后收集数据。
结果
在这些分析中，五个州提供了 367 名女性参与者的匿名数据，平均年龄为 63（±11）岁。大约 10 周每周两次的课程出勤率为 69.4%。采用配对 t 检验分析前后变化。所有高级体能测试指标均观察到显著改善（p<.01）。根据年龄组对数据进行分层，并与已发表的年龄相关标准进行比较。
结论
本研究表明，社区领袖对参与者进行前后身体适应性评估是可行的，并且参与者在几个重要的身体适应性领域都有所改善。
