ABSTRACT
The terms exercise-induced bronchospasm, exercise-induced broncho-
constriction, and exercise-induced asthma (EIA) all stand for transient air-
flow obstruction associated with physical exertion. EIA is a problem in all
age groups, but it is most frequently observed in children and young adults
because of their enthusiasm for vigorous activities. It occurs during or more
frequently after exercise in 10-50% of elite athletes with the highest prevalence among competitors in winter sports. Clinical presentation and timing
of EIA may point to the diagnosis, but the association of airway obstruction and exercise alone is not sufficient for confirmation, and the use of objective
measures of lung function is well advised. Although most exacerbations are
self-limited or subside readily with medication, mortality comparable to that of trauma and cardiac disease, generally regarded as the main cause
of unexpected death in young, highly trained athletes, has been reported
(2,3). It is important to anticipate EIA in all patients with asthma. Prompt
and accurate diagnosis together with sound treatment should keep the ath-
letes with EIA safe, allow them to enjoy the benefits of an active lifestyle,
and help them fulfill their competitive potential (4).
