Twentyfive normal male volunteers undergoing a ten weeks course in the practice of yoga have been studied by some parameters of ventilatory functions tests. The observations recorded at the end of ten weeks of the course have shown improved ventilatory functions in the form of lowered respiratory rate, increased forced vital capacity, FEV1, maximum breathing capacity and breath holding time, while tidal volume and %FEV1, did not reveal any significant change. Thus, a combined practice of yoga seems to be beneficial on respiratory efficiency.
对25名接受为期十周瑜伽练习课程的正常男性志愿者进行了通气功能测试的一些参数研究。在课程十周结束时记录的观察结果显示，通气功能有所改善，表现为呼吸频率降低、用力肺活量、第一秒用力呼气量、最大通气量和屏气时间增加，而潮气量和第一秒用力呼气量百分比没有显示出任何显著变化。因此，综合练习瑜伽似乎对呼吸效率有益。
