Summary
Regular physical activity can worsen lung function in children with asthma due to exercise-induced asthma (EIA). However, prophylactic medication and tailored training programs significantly improve lung function and overall well-being in these young patients.
Area of Science:
- Pediatric Pulmonology
- Allergy and Immunology
- Sports Medicine
Background:
- Physical activity can trigger a decline in lung function in children and adolescents with asthma.
- This phenomenon is known as exercise-induced asthma (EIA), characterized by bronchoconstriction after exertion.
- EIA can occur even in individuals with normal baseline lung function or subclinical obstruction.
Purpose of the Study:
- To investigate the impact of physical activity on lung function in asthmatic children and adolescents.
- To evaluate the effectiveness of prophylactic medication and specific training programs in managing EIA.
- To assess improvements in aerobic capacity, strength, and psychosocial well-being through physical training.
Main Methods:
- Lung function tests (spirometry) were performed before and after submaximal exercise on an ergometer or treadmill.
- Exercise intensity, duration, and type were varied to assess their impact on EIA.
- Prophylactic medications (disodium cromoglycate, beta-adrenergic drugs) were administered prior to exercise tests.
- Training programs incorporated interval principles with activities like swimming, ball games, and dancing.
Main Results:
- Approximately 85% of children experienced a significant fall (≥15%) in lung function after a six-minute ergometer cycle test.
- Prophylactic medication effectively reduced or abolished the EIA response in many cases.
- Physical training programs led to improvements in aerobic work capacity, muscle strength, and lung function.
- Training also resulted in enhanced mental resources and increased social integration.
Conclusions:
- Exercise-induced asthma is a common issue affecting lung function in asthmatic children during physical activity.
- Prophylactic medication and structured physical training are crucial for managing EIA and improving health outcomes.
- Comprehensive management including medication and exercise can enhance the physical, mental, and social well-being of asthmatic children.
