An observational study of Asthma, run by Bispebjerg Hospital at 1 site in Denmark.
Trial summary
Studies have shown that the prevalence of respiratory symptoms, airway hyperresponsiveness (AHR) and asthma is high and increasing in elite athletes.

About this study
Official title: Airway Inflammation in Swimmers: Development and Risk Factors
Studies have shown that the prevalence of respiratory symptoms, airway hyperresponsiveness (AHR) and asthma is high and increasing in elite athletes. The inflammation seen in the airways of elite athletes might differ from the inflammation seen in the airways of "ordinary" asthmatics and it might represent a different kind of asthma.
The primary purposes are
- To investigate the type of airway inflammation in young swimmers.
- To investigate the acute changes in airway inflammation after a short training session.
- Conditions
- Asthma
- Keywords
- Asthma, Airway inflammation, Sport
- Medical subject headings
