The prevalence of exercise-induced bronchoconstriction (EIB) is consistently reported to be greater in athletic individuals than in the general population (1). The reason for this difference remains to be fully determined but may be explained by the development of airway hyperresponsiveness arising from repeated episodes of exercise hyperpnea when performed in noxious environments (2). Equally, however, it is important that the prevalence of EIB is not overestimated (i.e., false positive) by the application of overly sensitive diagnostic test methodologies. The aim of this study was to determine the normative response to a eucapnic voluntary hyperpnea (EVH) challenge in a cohort of entirely asymptomatic athletes.
