Exercise Induced Bronchoconstriction
Exercise Induced Bronchoconstriction. EIB is a temporary inflammation and narrowing of your airways. Epidemiology Current literature suggests that the prevalence of exercise-induced bronchoconstriction (EIB) is significantly higher in athletes than in the general population at any age and equally between genders.
In the past this was a called exercise-induced asthma. It might be expected that people with E. B. would present with shortness of breath, and/or an elevated respiratory rate and wheezing, consistent with an asthma attack.
Your lung function is measured (with a test called spirometry) before and after exercise to look for changes that are seen with EIB.
EIB is caused by bronchial smooth muscle constriction in the lower airways due to the inhalation of dry air or allergens during exercise; it is associated with the release of bronchoconstricting mediators from airway cells.
ATS guidelines recommend differentiating exercise-induced bronchoconstriction (EIB) in patients with asthma from EIB in individuals without underlying asthma. Exercise-induced bronchoconstriction is acute airway narrowing that occurs as a result of exercise. Exercise-induced bronchoconstriction (EIB), also called exercise-induced asthma, is a narrowing of the airways in the lungs that is triggered by physical activity.
