Exercise-induced asthma after swimming and bicycle exercise
European Journal of Respiratory Diseases
|May 1, 1982
Summary
Exercise-induced asthma (EIA) triggers are equally potent during swimming and bicycling. Both activities caused a similar decrease in pulmonary function in adult patients with EIA.
Area of Science:
- Pulmonology
- Sports Medicine
- Exercise Physiology
Background:
- Exercise-induced asthma (EIA) is a common condition affecting athletes.
- Understanding the specific triggers and their intensity is crucial for managing EIA.
- Different exercise modalities may present varying stimuli for bronchoconstriction.
Purpose of the Study:
- To compare the effectiveness of swimming versus bicycle exercise in triggering EIA.
- To quantify the impact of these exercise types on pulmonary function in EIA patients.
Main Methods:
- Eleven adult patients diagnosed with EIA participated.
- Subjects underwent 6-minute swimming and bicycle exercise sessions on separate days.
- Controlled environmental conditions (temperature, humidity) and respiratory parameters were maintained.
- Pulmonary function was assessed before and after each exercise type.
Main Results:
- Average accumulated ventilation was comparable: 404 L for bicycling and 419 L for swimming.
- Pulmonary function decreased significantly and similarly after both exercises: 31% after bicycling and 30% after swimming.
Conclusions:
- Swimming and bicycling exercise are equally effective in eliciting EIA symptoms.
- The intensity of EIA triggers is comparable between these two distinct forms of physical activity.
