In 378 children affected by asthma and 87 healthy children, physical loading was carried out by three kinds of test, viz. free running, stairstep test or skipping, and bicycle ergometry. In 32% of healthy children physical exercise led to improved respiratory function, while this value was only 7% in asthmatics. An improvement in respiratory function exceeding 20%, i.e. appreciable bronchial dilatation, never occurred in asthma patients. The bronchospasm of healthy children showed no consistent time course, in asthmatics it was most pronounced three minutes after exercise. Exercise induced bronchospasm occurred most frequently after free running, least frequently after ergometric loading. The stairstep test and skipping provoked exercise induced bronchospasm in a nearly identical proportion. Severity of exercise induced bronchospasm exhibited a similar distribution. In addition to cases with a positive response to running test, some of the other methods revealed further 5-6% of cases. Free running is the most suitable method for demonstration of exercise induced bronchospasm, ergometric loading appears the least sensitive test in this respect. By application of three loading tests exercise induced bronchospasm could be demonstrated in 52% of paediatric asthma patients.
在378名哮喘患儿和87名健康儿童中，通过三种测试进行体力负荷试验，即自由跑步、阶梯试验或跳绳，以及自行车测力计测试。在32%的健康儿童中，体育锻炼使呼吸功能得到改善，而在哮喘患儿中这一比例仅为7%。哮喘患者中从未出现过呼吸功能改善超过20%，即明显支气管扩张的情况。健康儿童的支气管痉挛没有一致的时间进程，而哮喘患儿在运动后三分钟时支气管痉挛最为明显。运动诱发的支气管痉挛在自由跑步后最常发生，在测力计负荷后最少发生。阶梯试验和跳绳诱发运动诱发支气管痉挛的比例几乎相同。运动诱发支气管痉挛的严重程度呈现出相似的分布。除了对跑步试验有阳性反应的病例外，其他一些方法还发现了另外5 - 6%的病例。自由跑步是证明运动诱发支气管痉挛最合适的方法，测力计负荷在这方面似乎是最不敏感的测试。通过应用三种负荷试验，52%的小儿哮喘患者可表现出运动诱发支气管痉挛。
