The effects of different exercise training programs on the level of physical activity in daily life in patients with COPD remain to be investigated.
In patients with COPD we compared the effects of 2 exercise/training regimens (a high-intensity whole-body endurance-and-strength program, and a low-intensity calisthenics-and-breathing-exercises program) on physical activity in daily life, exercise capacity, muscle force, health-related quality of life, and functional status.
We randomized 40 patients with COPD to perform either endurance-and-strength training (no. = 20, mean ± SD FEV(1) 40 ± 13% of predicted) at 60-75% of maximum capacity, or calisthenics-and-breathing-exercises training (no. = 20, mean ± SD FEV(1) 39 ± 14% of predicted). Both groups underwent 3 sessions per week for 12 weeks. Before and after the training programs the patients underwent activity monitoring with motion sensors, incremental cycle-ergometry, 6-min walk test, and peripheral-muscle-force test, and responded to questionnaires on health-related quality of life and functional status (activities of daily living, pulmonary functional status, and dyspnea).
Time spent active and energy expenditure in daily life were not significantly altered in either group. Exercise capacity and muscle force significantly improved only in the endurance-and-strength group. Health-related quality of life and functional status improved significantly in both groups.
Neither training program significantly improved time spent active or energy expenditure in daily life. The training regimens similarly improved quality of life and functional status. Exercise capacity and muscle force significantly improved only in the high-intensity endurance-and-strength group.
不同运动训练方案对 COPD 患者日常生活体力活动水平的影响仍有待研究。
我们比较了 2 种运动/训练方案（高强度全身耐力和力量训练，以及低强度体操和呼吸训练）对 COPD 患者日常生活体力活动、运动能力、肌肉力量、健康相关生活质量和功能状态的影响。
我们将 40 例 COPD 患者随机分为耐力和力量训练组（n = 20，平均 ± 标准差 FEV1 为预计值的 40 ± 13%）或体操和呼吸训练组（n = 20，平均 ± 标准差 FEV1 为预计值的 39 ± 14%）。两组患者均每周进行 3 次训练，共 12 周。在训练计划前后，患者使用运动传感器进行活动监测、递增式踏车运动试验、6 分钟步行试验和外周肌肉力量测试，并对健康相关生活质量和功能状态（日常生活活动、肺功能状态和呼吸困难）的问卷进行了回答。
两组患者日常生活中的活跃时间和能量消耗均无显著变化。仅在耐力和力量训练组中，运动能力和肌肉力量显著改善。两组患者的健康相关生活质量和功能状态均显著改善。
两种训练方案均未显著改善日常生活中的活跃时间或能量消耗。两种训练方案同样改善了生活质量和功能状态。仅在高强度耐力和力量训练组中，运动能力和肌肉力量显著改善。
