BACKGROUND
Despite the recognized health benefits, few older women participate in strength-training exercises.
METHODS
The purpose of this study was to examine factors related to older women's adherence to strength training after participation in the StrongWomen Program, a nationally disseminated community program. Adherence was defined as > or =4 months of twice-weekly strength training. Surveys were sent to 970 program participants from 23 states and to participants' corresponding program leaders. Five-hundred fifty-seven participants responded (57%).
RESULTS
Of respondents who completed surveys (527), 79% (415) adhered to strength training; adherers reported a mean of 14.1 +/- 9.1 months of strength training. Logistic-regression analysis revealed that exercise adherence was positively associated with age (p = .001), higher lifetime physical activity levels (p = .045), better perceived health (p = .003), leader's sports participation (p = .028), and leader's prior experience leading programs (p = .006).
CONCLUSION
These data lend insight to factors that may be related to exercise adherence among midlife and older women.
背景
尽管已认识到力量训练对健康有益，但很少有老年女性参与力量训练运动。
方法
本研究旨在探讨参与“强壮女性计划”（一项全国推广的社区计划）后，与老年女性坚持力量训练相关的因素。坚持训练定义为每周进行两次力量训练且持续≥4个月。向来自23个州的970名项目参与者及其相应的项目负责人发送了调查问卷。557名参与者进行了回复（回复率为57%）。
结果
在完成调查问卷的受访者（527名）中，79%（415名）坚持进行力量训练；坚持训练者报告的力量训练平均时长为14.1±9.1个月。逻辑回归分析显示，运动坚持情况与年龄（p = .001）、较高的终生身体活动水平（p = .045）、更好的健康感知（p = .003）、负责人的体育参与情况（p = .028）以及负责人之前领导项目的经验（p = .006）呈正相关。
结论
这些数据为可能与中年及老年女性运动坚持情况相关的因素提供了见解。
