[Bronchial hyperreactivity in athletes].
Elite athletics, particularly endurance sports, are characterised by a high prevalence of bronchial hyperresponsiveness (BHR) and exercise-induced asthma (EIA). Findings in several studies suggest short-term high intensity physical activity to cause a transient increase in BHR. Recent studies in Oslo have shown that regular physical endurance training over several years, particularly when combined with such climatic factors as low air temperatures, may result in an increased risk of BHR and EIA among elite athletes--e.g., cross-country skiers. Inhalation beta 2-agonists and steroids have been used by many athletes in endurance sports, particularly skiers. Athletes with symptoms of BHR or EIA should be examined with lung function tests and exercise testing, and the effect of antiasthmatic drugs should be ascertained. Inhaled beta 2-agonists have no beneficial effect upon physical performance in nonasthmatic athletes, and may have a slight limiting effect upon physical endurance.
