RESISTANCE TRAINING IN OLDER WOMEN WITH CHD

描述(改编自申请者摘要)：冠心病 是导致残疾的主要原因，也是 美国女性。老年女性的习惯性体力活动水平较低。 以及比老年男性更低的身体功能水平，这在一定程度上可以解释 由于较低的力量和肌肉质量。老年女性冠心病患者更进一步 出于对安全的担忧，减少了他们的活动 身体活动，进一步加剧了他们的去条件反射。抵抗力 将训练作为一种增加体力活动和 老年女性冠心病患者的身体功能尚未进行检查。 这项研究计划的目标是确定 在心脏康复环境中进行的阻力训练： 使用双标记水、稳定同位素的自由生活体力活动 方法论、身体机能和身体成分，由 问卷调查、体能测试和双X射线吸收测量法。 总而言之，这些结果将检验这一假设 肌肉力量和肌肉质量的增加是 老年人习惯性体力活动和身体功能增加， 社区居所，女性冠心病患者。初步研究结果将 包括总自由生活体力活动的稳定同位素测量， 患者描述和研究人员观察的物理测量 功能，以及肌肉力量和肌肉质量的测量。总而言之， 本研究旨在为临床实践提供重要数据。 旨在增加体力活动和身体机能的干预措施 在老年女性冠心病患者中有功能障碍。

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.
