运动诱发性喉梗阻（EILO）发生在中度至剧烈运动时，伴有反常的声带运动或声门上塌陷。之前，Gallena等人（2015）报告了患有EILO的女性青少年运动员在静息潮气呼吸（RTB）期间的吸气（Ri）和呼气（Re）阻力低于正常值。这项研究旨在复制这一意想不到的结果。气流扰动装置（APD）测量Ri和Re在三个1分钟的RTB试验在16个十几岁的女运动员与EILO和16个性别，年龄和身高匹配的控制。多元线性回归分析了组、年龄、身高和体重作为Ri和Re的预测因素。EILO组的Ri和Re倾向于低于对照组[Ri：F（1，30）= 3.58，p = 0.068，d = 0.686; Re：F（1，30）= 3.28，p = 0.080，d = 0.640]，但总体效应无统计学显著差异[F（2，29）= 1.75，p = 0.192]。在去除EILO组和她的匹配对照的Re的一个离群值后，总体差异具有统计学显著性，F（2，27）= 3.38，p = 0.049，Re主要促成差异[Ri：F（1，28）= 3.66，p = 0.066，d = 0.719; Re：F（1，28）= 5.69，p = 0.024，d = 0.899]。这些结果并没有复制之前在有和没有EILO的十几岁女孩的静息潮气呼吸期间Ri和Re之间发现的强大差异，但是一旦从分析中删除离群值，结果就朝着相同的方向发展，并且符合统计学显著性标准。总体而言，大多数EILO少女的静息呼吸阻力较低的观察结果表明，喉部和/或下呼吸道的张力降低可能使年轻运动员易患EILO。
Exercise-induced laryngeal obstruction (EILO) occurs with paradoxical vocal fold motion or supraglottic collapse during moderate to vigorous exercise. Previously, Gallena et al. (2015) reported lower-than-normal inspiratory (Ri) and expiratory (Re) resistances during resting tidal breathing (RTB) in female teenage athletes with EILO. This study aimed to replicate that unexpected result. The Airflow Perturbation Device (APD) measured Ri and Re during three 1-minute trials of RTB in 16 teenage female athletes with EILO and 16 sex-, age- and height-matched controls. Multiple linear regression examined group, age, height, and weight as predictors of Ri and Re. Ri and Re tended to be lower in the EILO group than the control group [Ri: F(1,30) = 3.58, p = .068, d = .686; Re: F(1,30) = 3.28, p = .080, d = .640], but there was no statistically significant difference in the overall effect [F(2,29) = 1.75, p = .192]. After one outlier for Re from the EILO group and her matched control were removed, the overall difference was statistically significant, F(2,27) = 3.38, p = .049, with Re primarily contributing to the difference [Ri: F(1,28) = 3.66, p = .066, d = .719; Re: F(1,28) = 5.69, p = .024, d = .899]. These results did not replicate the robust differences found previously between Ri and Re during resting tidal breathing in teenage girls with and without EILO, but the results trended in the same direction and met criterion for statistical significance once an outlier was removed from analysis. Overall, the observation that resting respiratory resistances were lower in most teenage girls with EILO suggests that reduced tone of the laryngeal and/or lower airways may predispose young athletes to EILO.
