It has long been recognized, even during biblical times, that physical exercise may induce asthma symptoms in susceptible individuals. Nevertheless, the term exerciseinduced asthma (EIA) only became popular in the 1960s and 1970s when several reports addressed the pattern of airway response to exercise and the influence of drugs on EIA, particularly in children. Subsequently, reports of studies...

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...

Asthmatics often find that reasonably hard exercise of moderate duration like 6-8 minutes of continuous moderately hard running causes troublesome exercise induced asthma (EIA) while either very brief, intense exercise or very prolonged exercise does not necessarily cause an attack (Fitch et al, 1976). Neither the cause of EIA nor the reasons why some forms of exercise have greater propensity t...

BACKGROUND A fall in FEV(1) of > or =10% following bronchoprovocation (eucapnic voluntary hyperventilation (EVH) or exercise) is regarded as the gold standard criterion for diagnosing exercise induced asthma (EIA) in athletes. Previous studies have suggested that mid-expiratory flow (FEF(50)) might be used to supplement FEV(1) to improve the sensitivity and specificity of the diagnosis. A study...

Implicit motive research has shown that implicit motives are important predictors of behavior and well-being. However, little is known about the interrelationship between the different implicit motives measures frequently applied. We aimed to shed light on the convergent validity of three implicit motive measures and wanted to test their assumed statistical independence from three explicit moti...

Serum potassium concentrations were measured before, during, and after exercise in 32 patients with asthma (12 with exercise induced asthma), and in seven normal subjects. The changes in serum potassium in response to exercise did not differ significantly in the two groups or between those with and without exercise induced asthma. The potassium response to exercise is unlikely to be relevant to...
