A high prevalence of bronchial hyperresponsiveness (BHR) and respiratory symptoms has been reported among competitive swimmers. From the 2002 Winter Olympics, BHR measurements or bronchodilator reversibility have been required for approved use of β2-agonists in sports. The first aim of this study was to evaluate the relationship among respiratory symptoms in young elite swimmers, eucapnic voluntary hyperpnea (EVH), and the inhaled dose of methacholine, causing a 20% decrease in forced expiratory volume in 1 s (FEV1; PD(20 methacholine)). The second aim of this study was to assess the repeatability of the EVH test.
