Subjects with severe chronic obstructive pulmonary disease (COPD) were studied to evaluate the effects of breathing retraining (BRT) on exercise tolerance. Twenty-two subjects exercised on a treadmill three times weekly for six weeks. Twelve of the subjects (controls) then exercised for three more weeks; the other ten subjects received three more weeks of exercise reconditioning plus BRT. Results of routine pulmonary function and exercise tests were similar in both groups at the beginning of the study and after six weeks of exercise. However, in the last three weeks of the study, increments in exercise performance were significantly greater in the BRT subjects than in controls (P less than .002). Following BRT, respiratory rate during exercise decreased (P less than .005) and tidal volume and PaO2 during exercise increased (P less than .05). Thus, these data suggest that BRT increases exercise performance in subjects with severe COPD.
对患有严重慢性阻塞性肺疾病（COPD）的受试者进行了研究，以评估呼吸再训练（BRT）对运动耐力的影响。22名受试者每周在跑步机上锻炼3次，持续6周。其中12名受试者（对照组）随后又锻炼了3周；另外10名受试者接受了3周的运动康复训练加BRT。在研究开始时和锻炼6周后，两组的常规肺功能和运动测试结果相似。然而，在研究的最后3周，接受BRT的受试者的运动表现增量明显大于对照组（P小于0.002）。BRT后，运动期间的呼吸频率降低（P小于0.005），运动期间的潮气量和动脉血氧分压升高（P小于0.05）。因此，这些数据表明BRT可提高重度COPD患者的运动表现。
