【摘要】：目的：比较高强度与低强度有氧训练对轻中度稳定期COPD患者肺的通气功能和运动耐力的影响。方法：将60例轻中度稳定期COPD患者随机分为高强度(峰值功率的70%)有氧训练组20例、低强度(峰值功率的50%)有氧训练组20例、对照组20例,所有患者训练前后均进行心肺运动试验评估,高强度与低强度有氧训练组均进行12周训练,每周3次,高强度训练组每次训练4组,每组以5分钟训练、5分钟休息的间歇训练模式进行,共40分钟。低强度训练组每次持续训练20分钟。结果：训练前三组间的测试持续时间、峰值功率、峰值通气量、峰值摄氧量及无氧阈值均无差异(P0.05)。训练后各指标差值(训练后-训练前)比较,三组间测试持续时间、峰值功率、峰值摄氧量的差值(训练后-训练前)两两比较均有差异(P0.05),高强度组明显增加；对照组与低强度组间的峰值通气量无差异,但均与高强度组有差异(P0.05)；无氧阈值仅高强度组比对照组明显增高(P0.05)。结论： 1.有氧训练可以提高COPD患者的测试持续时间、峰值功率及峰值摄氧量,即提高COPD患者的运动耐力,并且与低强度持续有氧训练相比,高强度间歇有氧训练效果更为明显。 2.高强度间歇有氧训练能够增加COPD患者的峰值通气量及无氧阈值,从而改善通气功能及运动耐力,而低强度持续训练组改善不明显。 3.对于轻中度COPD患者,采用最大功率的70%作为高强度进行训练是可以耐受的,无不良事件发生,是安全有效的。
[Abstract]:Aim: to compare the effects of high intensity and low intensity aerobic training on ventilation function and exercise endurance in patients with mild to moderate stable COPD. Methods: sixty patients with mild to moderate stable COPD were randomly divided into high intensity aerobic training group (70 peak power), low intensity aerobic training group (50 peak power) and control group. All the patients underwent cardiopulmonary exercise test before and after training. The high-intensity and low-intensity aerobic training groups were trained for 12 weeks, 3 times a week, and 4 groups for each training in the high intensity training group. Each group was trained for 5 minutes and 5 minutes for a total of 40 minutes. The low intensity training group continued to train for 20 minutes each time. Results: there was no difference in test duration, peak power, peak ventilation volume, peak oxygen uptake and anaerobic threshold between the three groups before training. The difference of peak power and peak oxygen uptake (after training-before training) was significantly increased in the high intensity group, but there was no difference between the control group and the low intensity group, and there was no significant difference in the peak ventilation volume between the control group and the low intensity group. However, there was significant difference between the high intensity group and the high intensity group, and the anaerobic threshold was significantly higher in the high intensity group than in the control group. Conclusion:. 1. Aerobic training can improve the test duration, peak power and peak oxygen uptake of COPD patients, that is, improve the exercise endurance of COPD patients, and the effect of high-intensity intermittent aerobic training is more obvious than that of low-intensity continuous aerobic training. 2. High intensity intermittent aerobic training can increase the peak ventilation volume and anaerobic threshold of COPD patients, thus improve ventilation function and exercise endurance, but the improvement of low intensity continuous training group is not obvious. 3. For patients with mild and moderate COPD, it is safe and effective to use 70% of maximum power as high intensity training.
