Une spirométrie a été réalisée avant et immédiatement après un test d’effort sur le terrain (test de récupération intermittente : test Yo-Yo). Le diagnostic positif de la BIE a été posé si le volume expiratoire maximal de la première seconde (VEMS) diminuait de 10 % ou plus, par rapport à la valeur initiale, après l’exercice. Les symptômes respiratoires après le test d’effort ont été enregistrés.</div></div><div><h3>Résultats</h3><div>Après le test d’effort, 59,6 % des enfants souffraient de toux et 51,2 % souffraient de BIE. La prévalence de la dyspnée provoquée par l’effort était de 41,7 %. Les participants avec BIE avaient un VEMS post-exercice significativement inférieur à ceux ne présentant pas de BIE (<em>p</em>  =0,55, <em>p</em>     <0.01). Among participants with exercise related symptoms, 94.4% had EIB.
