The objective of our study was to investigate the effects of a home-based walking program on physical fitness and QOL among community residents. Subjects (n = 200, mean age: 64.2 years, range: 42 - 75 years) who participated in the 32-week trial were randomly allocated to one of two groups: an exercise (E) group and a control (C) group. The E group was instructed to increase the number of steps a day that they walked and to perform aerobic walking at a target heart rate for 20 minutes or more daily, 2 or more days a week. The C group was told to continue their normal level of activity. Outcome measures were the 3-minute shuttle stamina walk test (SSWT), 30-second chair-stand test (CS-30), and SF-36. Increases in SSWT values were significantly greater in the E group than in the C group (men 24.1 m vs. 6.3 m; women 8.8 m vs. 2.4 m), as were increases in CS-30 values (men 5.9 vs. 2.6; women 4.5 vs. - 0.1). On the SF-36, the scores in the E group for vitality and mental health increased significantly. Home-based walking is considered to be an effective and feasible method to improve physical fitness and QOL among community residents.
我们研究的目的是调查居家步行计划对社区居民身体素质和生活质量的影响。参与这项为期32周试验的受试者（n = 200，平均年龄：64.2岁，范围：42 - 75岁）被随机分为两组：运动（E）组和对照组（C）组。E组被要求增加每日步行步数，并以目标心率进行有氧步行，每天20分钟以上，每周2天或更多天。C组被告知维持其正常活动水平。结果指标为3分钟往返耐力步行测试（SSWT）、30秒坐立试验（CS - 30）和SF - 36。E组SSWT值的增加显著大于C组（男性：24.1米对6.3米；女性：8.8米对2.4米），CS - 30值的增加也是如此（男性：5.9对2.6；女性：4.5对 - 0.1）。在SF - 36量表上，E组的活力和心理健康得分显著提高。居家步行被认为是改善社区居民身体素质和生活质量的一种有效且可行的方法。
