This study describes the result of free-running exercise performed on 40 asthmatic subjects and 40 age and sex matched controls. A percentage fall of more than 15% in PEFR was used for the diagnosis of exercise-induced asthma (EIA). 77.5% of our asthmatic patients had exercise-induced bronchoconstriction (EIB) while none of the control subjects exhibited EIB. Twenty-seven patients gave positive history of EIA out of which 25 (92.59%) had positive exercise testing. Conversely, 13 patients with asthma did not give history of EIA but 6 of this (46.15%) were found to have EIB on exercise. History alone is therefore insufficient to diagnose patients with exercise-induced asthma.
本研究描述了对40名哮喘患者以及40名年龄和性别匹配的对照者进行自由运动锻炼的结果。呼气峰值流速（PEFR）下降超过15%用于诊断运动诱发性哮喘（EIA）。我们的哮喘患者中有77.5%患有运动诱发性支气管收缩（EIB），而对照者中无人表现出EIB。27名患者有EIA阳性病史，其中25名（92.59%）运动试验呈阳性。相反，13名哮喘患者没有EIA病史，但其中6名（46.15%）在运动时被发现患有EIB。因此，仅凭病史不足以诊断运动诱发性哮喘患者。
