This study examined whether psychological, physiological, and health and lifestyle measures were associated with adherence to a structured exercise program for older women. Women aged "60 to 85 years (N = 102)," randomly recruited from the community, were assessed on these measures before and after a 12-month exercise trial. Sixty-nine women completed the trial, and 54 continued participation after the trial for at least 6 months. Adherence was examined at various stages during the trial. Multiple regression analysis revealed that reduced muscle strength, slow reaction time, and psychoactive drug use explained most of the variance in adherence during the trial. In contrast, muscle strength, reasoning ability, depression, and self-reported improvement in strength best predicted continued participation after the trial. The findings have implications for community-based exercise programs and research trials.
本研究调查了心理、生理、健康及生活方式等因素是否与老年女性坚持结构化锻炼计划有关。从社区中随机招募了102名年龄在60至85岁的女性，在为期12个月的锻炼试验前后对她们进行了这些方面的评估。69名女性完成了试验，其中54名在试验结束后继续参与锻炼至少6个月。在试验的不同阶段对坚持情况进行了考察。多元回归分析显示，肌肉力量下降、反应时间减慢和使用精神活性药物可解释试验期间坚持情况的大部分差异。相比之下，肌肉力量、推理能力、抑郁以及自我报告的力量改善情况最能预测试验结束后的持续参与情况。这些研究结果对基于社区的锻炼计划和研究试验具有启示意义。
