The effect of inspiratory resistive breathing training using a simple apparatus was tested in 27 optimally medicated consecutive outpatients with severe chronic airflow limitation, randomly assigned to a test and a control group. Patients trained in their homes for up to 10 min thrice daily and increments in resistance were made, if possible, every fortnight. The control group used the same apparatus, but without inspiratory resistance. Three months from the start of training, the following statistically significant differences between the 2 groups were observed: a marked decrease in dyspnea in the trained group, a 60% versus 22% rise in endurance time on a cycle ergometer at 2/3 of maximal work load, a fall in functional residual capacity, and a fall in respiratory frequency both at rest and during exercise.
使用一种简单装置进行吸气阻力呼吸训练的效果，在27名接受最佳药物治疗的重度慢性气流受限连续门诊患者中进行了测试，这些患者被随机分为测试组和对照组。患者在家中训练，每天三次，每次最多10分钟，如有可能，每两周增加一次阻力。对照组使用相同的装置，但没有吸气阻力。从训练开始三个月后，观察到两组之间存在以下统计学上的显著差异：训练组呼吸困难明显减轻；在最大工作负荷的2/3时，训练组在自行车测力计上的耐力时间提高了60%，而对照组仅提高了22%；功能残气量下降；静息和运动时呼吸频率均下降。
