Testing of pulmonary function in a professional cycling team

Asthma affecting elite athletes has been studied mainly in subjects practicing winter sports. The aim of our study was to test the pulmonary function in order to evaluate bronchial hyper-responsiveness prevalence in a team of 25 male professional cyclists (27.9+/-3.9 years old with a VO(2max) equal...

Description
Summary:Asthma affecting elite athletes has been studied mainly in subjects practicing winter sports. The aim of our study was to test the pulmonary function in order to evaluate bronchial hyper-responsiveness prevalence in a team of 25 male professional cyclists (27.9+/-3.9 years old with a VO(2max) equal to 69.9+/-6.6 mL.min(-1) x kg(-1)). Using a questionnaire that queried the presence or absence of asthma history or common symptoms of exercise induced bronchospasm, 72% of the subjects had upper airway or bronchial symptoms. Using a pneumotachograph, we recorded a forced flow-volume curve at rest, after a maximal exercise test with ambient air, and after beta2-agonist inhalation, then during a methacholine challenge. In our study, 52% of the subjects showed clinical symptoms associated with bronchial responsiveness during methacholine test, a proportion which is much higher than the average population (3-20%). However, ERS-ATS pulmonary function testing criteria at rest (reduced FEV1, FEV1/FVC, FEF25-75%) were not fulfilled by any of them. In the asthmatic group, O2max was significantly higher (70.5+/-6 vs 68.6+/-8.2 mL.min-1.kg-1, P
