Exercise-induced bronchoconstriction (EIB) occurs when the airways narrow as a result of exercise. This condition has been referred to as exercise-induced asthma (EIA); however, this term is no longer preferred. [1] While exercise does not cause asthma, it is frequently an asthma trigger. [1]
More generally termed exercise-induced asthma, the preferred and more accurate term exercise-induced bronchoconstriction better reflects underlying pathophysiology.It is also preferred due to the former term giving the false impression that asthma is caused by exercise.
Other types of triggers like exercise, air pollutants, tobacco smoke, humidity, cold air, or certain medicines may also play a role in triggering asthma. [4] While it has been proposed that asthma triggers can be classified into three types: allergic triggers, environmental triggers and physical triggers, a universal categorization of asthma ...
Exercise-induced asthma, technically called exercise-induced bronchoconstriction, or EIB, can make working out feel downright painful, if not altogether impossible. A narrowing of the airways that ...
Exercise can trigger bronchoconstriction both in people with or without asthma. [116] It occurs in most people with asthma and up to 20% of people without asthma. [116] Exercise-induced bronchoconstriction is common in professional athletes. The highest rates are among cyclists (up to 45%), swimmers, and cross-country skiers. [117]
Exercise can trigger asthma, but many athletes can still compete and succeed in sports with the condition. According to a 2023 study in the Scandinavian Journal of Medicine and Sports , asthma ...
Asthma is usually triggered by breathing in things in the air such as dust or pollen that produce an allergic reaction. It may be triggered by other things such as an upper respiratory tract infection, cold air, exercise, or smoke. Asthma is a common condition and affects over 300 million people around the world. [3]
In children, the most common triggers are viral illnesses such as those that cause the common cold. [22] Exercise or intense use of respiratory system—the effects of which differ somewhat from those of the other triggers, since they are brief. They are thought to be primarily in response to the exposure of the airway epithelium to cold, dry air.
