Exercise induced bronchoconstriction (EIB) is characterized by a transient airway constriction during or after vigorous physical activity. This clinical condition is more prevalent in asthmatic patients. The prevalence of EIB in competitive athletes is high; however, EIB is under-diagnosed in this specific athlete population. The present study described a case report of a male 23 year-old long distance runner who, despite not presenting previous asthma history, presented chest squeak and decline on spirometric performance after a cardiopulmonary exercise testing. After specific testing, the athlete was diagnosed as positive EIB. A clinical treatment with bronchodilator was then initiated and after 30 days an important increase in his oxygen uptake peak (VO2peak) was observed.
