To determine whether a home-based exercise program is able to increase functional capacity (FC) and reduce heart rate variability (HRV) in postmenopausal women with coronary heart disease.
Regular exercise training has been shown to improve both FC and HRV. However, those studies were conducted within institutional training programs, and few have included women.
Thirty-two postmenopausal women were randomly assigned to either an experimental or control group with 16 participants in each group. Those in the experimental group underwent home-based exercise training, 3 times a week for 8 weeks. On the first and final week, each participant's HRV was measured, and their FC was evaluated using a 6-minute walking test.
After 8 weeks, the FC of those who had undergone the home-based exercise program showed a significant improvement compared with subjects in the control group (P = .001). The total power (ms2), high-frequency (ms2), and low-frequency (ms2) indexes of HRV were also significantly improved over control values.
In postmenopausal women with coronary heart disease, a home-based exercise program appears able to improve FC and HRV.
确定基于家庭的运动方案是否能够增加绝经后冠心病女性的功能能力（FC）并降低心率变异性（HRV）。
有研究表明，有规律的运动训练可以提高 FC 和 HRV。然而，这些研究都是在机构培训项目中进行的，且很少有包含女性的研究。
32 名绝经后女性被随机分配到实验组或对照组，每组 16 名参与者。实验组进行基于家庭的运动训练，每周 3 次，共 8 周。在第 1 周和第 8 周，每位参与者的 HRV 都进行了测量，其 FC 通过 6 分钟步行测试进行评估。
经过 8 周后，与对照组相比，进行家庭运动训练的参与者的 FC 有显著改善（P=0.001）。HRV 的总功率（ms2）、高频（ms2）和低频（ms2）指标也明显高于对照组。
对于绝经后冠心病女性，基于家庭的运动方案似乎能够提高 FC 和 HRV。
