Patients with asthma often report symptoms of exercise-induced bronchoconstriction. We performed cardiopulmonary exercise testing to establish the cause of exercise limitation in patients with asthma, under treatment, who reported symptoms of exercise-induced bronchoconstriction. Ten of the 42 patients meeting criteria for inclusion in our study (24%) developed exercise-induced bronchoconstriction. Exercise limitation without exercise-induced bronchoconstriction was found in both obese and non-obese patients, suggesting that poor fitness is a problem independent of body habitus. Including cardiopulmonary exercise testing in the management of children with suspected exercise-induced bronchoconstriction would provide a better understanding of the etiology of their symptoms and facilitate more appropriate treatment.
哮喘患者常报告运动诱发支气管收缩的症状。我们对正在接受治疗且报告有运动诱发支气管收缩症状的哮喘患者进行了心肺运动试验，以确定运动受限的原因。符合我们研究纳入标准的42例患者中有10例（24%）出现运动诱发支气管收缩。在肥胖和非肥胖患者中均发现了无运动诱发支气管收缩的运动受限情况，这表明身体适应性差是一个与身体体型无关的问题。在疑似运动诱发支气管收缩的儿童管理中纳入心肺运动试验，将有助于更好地理解其症状的病因，并促进更恰当的治疗。
