DESCRIPTION: (Adapted from investigator's abstract) The purpose of this study is to determine the effectiveness of a 24-week home-based, moderate intensity walking program in alleviating common physical and psychological health symptoms and improving physical fitness and exercise behavior in sedentary employed midlife women. The specific aims are: (1) to compare women's health symptoms, physical fitness, and exercise motivation after completing the walking program with their own preprogram measures and those of a control group of nonexercisers; (2) to identify relationships among the amount of change in pre- to postprogram health symptoms and physical fitness; (3) to compare health symptoms, physical fitness, and exercise motivation measures 24 weeks after completing the walking program with immediate postprogram scores; and, (4) to determine the effect of the walking program on the relationships between health symptoms and their known correlates (i.e., role quality, menopausal status, menopausal attitude). Subjects will be 174 apparently healthy, sedentary, nonobese women aged 40-60 who are experiencing health symptoms common to midlife women and who are not on HRT, are not pregnant, and have not had a bilateral oophorectomy. Volunteers will be sought from large organizations with employees representing diverse ethnic and socioeconomic groups. Subjects will be randomly assigned to an experimental or control group in an experimental crossover design. The proposed intervention will require no equipment and will be carried out at times and locations convenient to the individual women. Walking will be prescribed at 50-74% HRmax reserve and progress from 20 to 30 minutes of continuous walking 4 times per week over a 24-week period. At the end of 24 weeks, the control group will begin the same program, and the experimental group will be monitored for 24 weeks more to determine whether they continue the walking program. Adherence during the intervention phase will be assessed by exercise logs and wireless heart rate monitors and during the continuation phase by exercise logs only. Every 2 weeks the experimental group will complete health symptoms measures and receive feedback and support for adherence and progress. The control group will also complete the health symptoms measures every 2 weeks to monitor symptoms and to control for contact with the experimental group. Other measures administered to both groups at 0 and 24 weeks will address factors known to influence symptoms at midlife (menstrual history; hormonal assays of follicle-stimulating hormone, estradiol, estrone; attitude toward menopause; role quality); exercise motivation (exercise self-efficacy, exercise self-determinism); and physical fitness, including aerobic fitness (maximal exercise test), body composition (body mass index, dual-energy x-ray absorptiometry), and flexibility (digital inclinometer). Exercise motivation, physical fitness, and health symptoms will be reassessed at 48 weeks. The walking program is the independent variable; dependent variables are health symptoms, fitness, exercise motivation, and continuation. Planned analyses include ANOVA, repeated-measures ANOVA, paired comparison t tests, and multiple regressions. Positive outcomes will support the effectiveness of home-based, moderate intensity exercise for nonpharmacological relief of health symptoms.

描述：（改编自研究者的摘要）此目的 研究的目的是确定为期 24 周的家庭适度的有效性 强度步行计划在缓解常见的身体和心理方面 健康症状以及改善身体素质和运动行为 久坐的中年职业女性。 具体目的是：（1）比较 女性健康症状、身体素质和运动动机 用他们自己的预计划措施和那些完成步行计划 由不锻炼者组成的对照组； (2) 识别之间的关系 项目前后健康症状和身体状况的变化量 健康; (3)比较健康症状、体质、运动情况 完成步行计划 24 周后的动机测量 项目结束后立即获得的分数； (4) 确定效果 关于健康症状与其已知症状之间关系的步行计划 相关性（即角色质量、更年期状况、更年期态度）。 受试者为 174 名表面健康、久坐、不肥胖的老年女性 40-60 岁正在经历中年女性常见的健康症状，并且 未接受 HRT、未怀孕且未进行双侧卵巢切除术。 将从拥有员工的大型组织中寻找志愿者 代表不同的种族和社会经济群体。 科目将是 在实验中随机分配到实验组或对照组 交叉设计。 拟议的干预措施不需要任何设备， 将在个人方便的时间和地点进行 女性。 步行将被规定为 50-74% HRmax 储备和进度 24 周内每周连续步行 4 次，每次 20 至 30 分钟 时期。 24周结束时，对照组将开始相同的 计划，并对实验组进行为期 24 周的监测，以 确定他们是否继续步行计划。 期间遵守 干预阶段将通过运动日志和无线心率进行评估 在持续阶段仅通过练习日志进行监控。 每 2 实验组将完成健康症状测量周 接收有关坚持和进步的反馈和支持。 对照组 还将每两周完成一次健康症状措施进行监测 症状并控制与实验组的接触。 其他 两组在 0 周和 24 周时采取的措施将解决这些因素 已知会影响中年症状（月经史；荷尔蒙测定） 卵泡刺激素、雌二醇、雌酮；对的态度 绝经;角色品质）；运动动机（运动自我效能感， 实行自决主义）；和身体健康，包括有氧健身 （最大运动测试）、身体成分（体重指数、双能 X 射线吸收测定法）和灵活性（数字倾斜仪）。 锻炼 动机、身体素质和健康症状将在 48 岁时重新评估 几周。 步行程序是自变量；因变量 是健康症状、健康状况、运动动机和持续性。 计划分析包括方差分析、重复测量方差分析、配对比较 测试和多元回归。 积极成果将支持 在家进行中等强度运动的有效性 非药物缓解健康症状。
