Objective: To review the most important causes of exercise-induced respiratory symptoms in adolescents.
Data sources: Published English-language medical literature.
Study selection: Primary literature and consensus publications relevant to the objective.
Results: The diagnosis and treatment of exercise-induced asthma are well characterized. Other syndromes, such as exercise-induced vocal cord dysfunction, exercise-induced paradoxical arytenoid motion, and exercise-induced hyperventilation, are relatively common but so far are described primarily in uncontrolled case reports.
Conclusion: Controlled studies are necessary to define efficient diagnostic and treatment algorithms for young patients experiencing respiratory symptoms during exercise who do not respond to asthma treatment.
