Prevalence of Exercise-Induced Asthma in Select Cohorts of College Athletes
Completed
Conditions studied: Asthma
In brief
This study is investigating how commonly exercise-induced asthma happens in athletes and the best way to diagnose exercise-induced asthma. Exercise-induced asthma describes narrowing of the airways in the lungs that occurs in certain people when they exercise. This can cause shortness of breath, cough, and fatigue during exercise and can impair athletic performance. Exercise-induced asthma can be difficult to diagnose. This is a research study, because the investigators are examining the best way to document a diagnosis of exercise-induced asthma. The investigators are also interested in examining why exercise-induced asthma may occur.

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: accepted.
You may qualify if…
- Varsity athlete on athletic team of interest here at The Ohio State University
- 18 years of age or older
- No short-acting bronchodilator use for 6 hours prior to testing
- No long-acting bronchodilator use for 36 hours prior to testing
- No inhaled corticosteroids or leukotriene modifiers for 72 hours prior to testing
- Non-smoker for 6 months or longer
- Less than 10 pack year (number of packs per day (x) years of smoking=pack years) smoking history, as smoking causes chronic changes in the profile of inflammatory cells of lungs and also makes airways more likely to spasm. This is true even for non-smokers
You may not qualify if…
- pregnancy
- recent upper respiratory tract infection (within 2 weeks of study enrollment)
- Objective evidence of severe lung impairment on pulmonary testing performed at the beginning of the study.
- Participation in another interventional research trial
- Unable to provide consent
- Asthma exacerbation within the last 4 weeks
Where it is running
- The Ohio State University — Columbus, Ohio, United States
