运动性哮喘(Exercise-indused asthma,EIA)/运动性气道痉挛(Exercise-induced bronchoconstriction,EIB)是指剧烈运动引起的短时气道阻力增加。据统计,运动可以诱发50%~80%的哮喘患者出现急性发作,此外,还有流行病学调查发现有超过60%存在运动后气道痉挛的患者静息肺功能是正常的,而且从未有过哮喘发病的病史;还有研究表明,在运动后最大呼气流量(PEF)下降超过20%的患者中,有25%的人从未有过任何不适主诉,说明运动性哮喘(气道痉挛)在正常人群中也广为存在。由运动诱发的哮喘和气道痉挛在优秀运动员群体中的发
Exercise-induced asthma (EIA) / Exercise-induced bronchoconstriction (EIB) refers to short-term airway resistance increase due to vigorous exercise. According to statistics, exercise can induce 50% to 80% of patients with acute asthma attacks, in addition, there are epidemiological survey found that more than 60% of patients with post-exercise airway spasm resting lung function is normal and never There have been a history of asthma attacks; other studies have shown that 25% of patients who have experienced a greater than 20% reduction in maximum expiratory flow (PEF) after exercise have never had any complaints of discomfort, indicating that exercise-induced asthma (airway Spasm) is also widespread in the general population.
