“…Studies performed in US Olympic athletes show an increasing trend of the disease with 9.7% in 1976, 16.7% in 1996 ( 34 ), and 21.9% both at Nagano Winter Games ( 35 ) and at the Sydney 2000 Games ( 36 ) being reported. Between 4.2 and 7.7% of Olympic Athletes had a confirmed diagnosis of asthma with a positive bronchodilator or a bronchoprovocation test in 2006, 2008, and 2010 Olympic Games ( 37 ). In certain groups of athletes, such as swimmers and skiers, prevalence is even higher compared to the athlete population in general.…”

The terms ‘exercise-induced asthma’ (EIA) and ‘exercise-induced bronchoconstriction’ (EIB) are often used interchangeably to describe symptoms of asthma such as cough, wheeze, or dyspnoea provoked by vigorous physical activity. In this review, we refer to EIB as the bronchoconstrictive response and to EIA when bronchoconstriction is associated with asthma symptoms. EIB is a common occurrence for most of the asthmatic patients, but it also affects more than 10% of otherwise healthy individuals as shown by epidemiological studies. EIA and EIB have a high prevalence also in elite athletes, especially within endurance type of sports, and an athlete's asthma phenotype has been described. However, the occurrence in elite athletes shows that EIA/EIB, if correctly managed, may not impair physical activity and top sports performance. The pathogenic mechanisms of EIA/EIB classically involve both osmolar and vascular changes in the airways in addition to cooling of the airways with parasympathetic stimulation. Airways inflammation plays a fundamental role in EIA/EIB. Diagnosis and pharmacological management must be carefully performed, with particular consideration of current anti-doping regulations, when caring for athletes. Based on the demonstration that the inhaled asthma drugs do not improve performance in healthy athletes, the doping regulations are presently much less strict than previously. Some sports are at a higher asthma risk than others, probably due to a high environmental exposure while performing the sport, with swimming and chlorine exposure during swimming as one example. It is considered very important for the asthmatic child and adolescent to master EIA/EIB to be able to participate in physical activity on an equal level with their peers, and a precise early diagnosis with optimal treatment follow-up is vital in this aspect. In addition, surprising recent preliminary evidences offer new perspectives for moderate exercise as a potential therapeutic tool for asthmatics.

“…In a similar study carried out among US Winter Olympians in Nagano 2 years later, 22% of athletes had previously been diagnosed with asthma, while over 18% had ever used asthma medication . According to more recent data , percentage of athletes using inhaled β‐mimetics varied from 3.6% during Atlanta Summer Games to 7.7% among participants in the Winter Olympics in Turin in 2006. Higher prevalence of asthmatic symptoms in top athletes, when compared with the general population, has also been reported by other authors .…”
