Studies on exercise-induced bronchoconstriction (EIB) in team sports are lacking. The aim of this study was to screen for EIB among amateur teenage football players in Tunisia and to compare EIB prevalence between regions.
One hundred ninety-six male football players (mean age [SD], 13.5 [0.5] yrs), practicing in three different cities of Tunisia (Tunis, Sousse and Sfax), underwent an outdoor free run of 7 minutes. Forced expiratory volume in one second (FEV subset1) was recorded prior to and at 0, 3, 5, 10, 15, 20 and 30 minutes after the run. Players were screened for EIB positivity defined as a greater than 10% decline in FEV subset1 from the resting value at any timepoint.
FEV1 decreased more than 10% in 30% of the players. EIB positivity was more common in Sfax (15.8%) than in Tunis (7.7%) (P=.03). Air humidity during the study was higher in Tunis.
EIB is prevalent among amateur teenage football players in Tunisia. The prevalence differs between regions and seems to be dependent on air humidity levels.
关于团队运动中运动诱发支气管收缩（EIB）的研究较少。本研究旨在筛查突尼斯业余青少年足球运动员中的EIB，并比较不同地区的EIB患病率。
196名男性足球运动员（平均年龄[标准差]，13.5[0.5]岁），在突尼斯的三个不同城市（突尼斯市、苏塞和斯法克斯）训练，进行了7分钟的户外自由跑。在跑步前以及跑步后0、3、5、10、15、20和30分钟记录一秒用力呼气量（FEV₁）。对运动员进行EIB阳性筛查，定义为在任何时间点FEV₁较静息值下降超过10%。
30%的运动员FEV₁下降超过10%。EIB阳性在斯法克斯（15.8%）比在突尼斯市（7.7%）更常见（P = 0.03）。研究期间突尼斯市的空气湿度较高。
EIB在突尼斯业余青少年足球运动员中普遍存在。患病率在不同地区有所不同，且似乎取决于空气湿度水平。
