Elite athletes in endurance sports face a higher risk of bronchial hyperresponsiveness and exercise-induced asthma, especially with prolonged training in cold climates. Medications like inhaled beta 2-agonists may not aid performance in non-asthmatic athletes.

Area of Science:

  • Sports Medicine
  • Pulmonology
  • Exercise Physiology

Context:

  • Elite endurance athletes exhibit high rates of bronchial hyperresponsiveness (BHR) and exercise-induced asthma (EIA).
  • Prolonged endurance training, particularly in cold environments, is linked to increased BHR and EIA risk in elite athletes like cross-country skiers.
  • Short-term high-intensity exercise can transiently increase BHR.

Purpose:

  • To investigate the prevalence and risk factors associated with BHR and EIA in elite endurance athletes.
  • To evaluate the impact of training, climate, and medication on respiratory health in this population.
  • To inform diagnostic and therapeutic strategies for athletes with respiratory symptoms.

Summary:

  • Regular, long-term endurance training, especially in cold conditions, increases the risk of BHR and EIA in elite athletes.

  • Inhaled beta 2-agonists and steroids are commonly used by affected athletes.
  • Diagnostic lung function and exercise testing are recommended for symptomatic athletes; inhaled beta 2-agonists offer no performance benefit and may hinder endurance in non-asthmatic athletes.

    • Impact:

    • Highlights the occupational respiratory risks for elite endurance athletes.
    • Underscores the need for careful respiratory health monitoring and management in this group.
    • Provides evidence-based guidance on the use of bronchodilators in athletic populations.
