Asthma and physical activity

    Summary
    This summary is machine-generated.

    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.
