The changes during exercise would be felt by the athlete during an event, and could impact performance. Determining why lung function changes during exercise can help us learn more about exercise-induced asthma, which will help us teach people to better manage their disease. The researchers will study the effects of certain hormones or other naturally released substances that could affect lung function during exercise, and the effects of temperature change and breathing pattern. By testing patients with asthma, Mayo Clinic researchers hope to identify under what conditions airways constrict, making the test subjects feel tightness in the chest or wheezy, and what conditions make airways dilate or allow the subject to breathe easier. Subjects must be asthmatic and under treatment for asthma.
Researchers prefer someone with mild asthma.
Study participants cannot be taking oral steroid medications, and researchers prefer that participants not be taking inhaled steroids. Participants do not have to be athletes, but should be able to perform exercise on a stationary cycle. They should not be markedly overweight, and cannot be a current cigarette smoker. Researchers are especially interested in participants who are a member of a racial minority. Include your name, affiliation, and e-mail address.
