描述（改编自申请人的摘要）：冠心病 是导致残疾和死亡的主要原因， 美国女人 老年妇女的习惯性体力活动水平较低 以及身体机能水平低于老年男性，这在一定程度上解释了 力量和肌肉质量下降 老年女性冠心病患者进一步 由于担心他们的安全， 身体活动，进一步加剧了他们的失调。 电阻 训练作为一种治疗方式，以增加身体活动， 老年女性冠心病患者的身体功能尚未得到检查。 这项研究计划的目标是确定 阻力训练，在心脏康复环境中进行，针对： 使用双标记水、稳定同位素的自由生活身体活动 方法、身体机能和身体成分， 问卷调查、体能测试和双能X线吸收测定法。 总的来说，这些结果将检验假设， 肌肉力量和肌肉质量的增加是 增加老年人的习惯性体力活动和身体功能， 社区住宅女性冠心病患者 主要研究结果将 包括自由生活体力活动总量的稳定同位素测量， 患者描述和医生观察的身体指标 功能，以及肌肉力量和肌肉质量的测量。 总的来说， 本研究旨在为临床实践提供重要数据， 旨在增加身体活动和身体机能的干预措施 老年女性冠状动脉患者的功能障碍。

DESCRIPTION (Adapted from the Applicant's Abstract): Coronary Heart Disease is a leading cause of disability and the leading cause of death among American women. Older women have lower levels of habitual physical activity and lower levels of physical functioning than older men, explained in part by lower strength and muscle mass. Older female coronary patients further curtail their activities due to apprehension regarding the safety of physical activities, further compounding their deconditioning. Resistance training as a therapeutic modality to increase physical activity and physical functioning in older female CHD patients has not been examined. The goals of this research program are to determine the effects of resistance training, delivered in a cardiac rehabilitation setting, on: free-living physical activity using doubly-labeled water, stable isotope methodology, physical functioning and body composition, measured by questionnaire, physical performance testing and dual x-ray absorptiometry. Collectively, these results will test the hypothesis that significant increases in muscle strength and muscle mass are important determinants of increased habitual physical activity and physical functioning in older, community dwelling, female coronary patients. Primary study outcomes will include stable isotope measures of total free-living physical activity, patient-described and investigator-observed measures of physical functioning, and measures of muscle strength and muscle mass. In summary, this study is intended to provide important data on a practical clinical intervention aimed at increasing physical activity and physical functioning in older female coronary patients with functional disability.
