Exercise induced asthma: real or imagined?

Is Exercise-Induced Bronchoconstriction Exercise-Induced Asthma?

The article in this issue of RESPIRATORY CARE by Burnett et al1 reports that 34 of 80 college athletes had exerciseinduced bronchoconstriction (EIB), most in the absence of symptoms. The authors further suggest that these athletes are at risk and that the identification of those with EIB may prevent morbidity and mortality. The implication is that the presence of EIB is evidence for asthma. But...

Exercise-induced asthma.

A review of exercise-induced asthma is presented which describes work that has been carried out by the authors and by other investigators over recent years. The effect of exericse on lung function in asthmatic and normal subjects is compared. The influence of the type and severity of exercise on the response of the asthmatic is noted and the importance this has for interpretation of results. Th...

[Exercise-induced asthma].

All asthmatics have exercise-induced asthma (EIA). In periods where the asthma spontaneously deteriorate, there will be more exercise-induced asthma. About 3/4 of the asthmatics will have a positive exercise test on the first challenge. Exercise is not the best test to obtain the diagnosis of asthma, as other tests, e.g. inhalation of histamine, is more sensitive and specific. The best pretreat...

Exercise-induced asthma: the "silent asthma".

Specificity of exercise in exercise-induced asthma.

Ventilatory function after three types of exercise-running, cycling, and swimming-was studied in 10 control subjects and 40 asthmatic patients. All performed eight minutes of submaximal aerobic exercise during each of the programmes, which were conducted in a randomly selected order. Biotelemetric monitoring of heart rates was used to equate the intensity of the exertion undertaken during the t...
