Exercise-induced bronchoconstriction (EIB) is a transient airflow obstruction that usually occurs 5 to 15 minutes after physical exertion. Although this condition is preventable, it is still underrecognized and affects the quality of life. The purpose of this study was to evaluate the prevalence of EIB, to find out whether self-reported symptoms were enough to establish the diagnosis of EIB and to define related symptoms and risk factors among symptomatic students of a Sports Academy in our city, which is situated at about 2,000 meters altitude and experiences a long winter period. A questionnaire was sent to students of the Sports Academy. After its evaluation, symptomatic students were invited to perform a pulmonary function test (PFT) before and after a six minute exercise test. Two hundred and seventy-seven students (205 males and 72 females, mean age: 20 +/- 4) from 12 different types of sport replied to the questionnaire. Of these subjects, 43% were symptomatic. Out of the 119 symptomatic students, 63 accepted our invitation. Three of them were excluded. After performing a six-minute exercise test, EIB was observed in 5 (8%) of them, whose symptoms were aggravated by cold weather. Our results suggest that EIB may be common among symptomatic sportsmen. Screening is important, since EIB could be prevented with appropriate diagnosis and treatment. Although respiratory symptoms during exercise may give important clues, only these symptoms Eire not sufficient to establish the diagnosis of EIB. Symptomatic patients should undergo further tests for EIB.
