RESUMO
The prevalence of exercise-induced asthma (EIA) after six minutes of standard exercise test on bicycle ergometer was studied in thirty healthy first degree relations of asthmatic subjects (group II) and was compared with that in thirty healthy controls (group I). Pulmonary function tests (PFT) measuring FVC, FEV1, FEF25-75% and PEFR were performed on each subject prior of exercise, immediately following exercise period and serially at 5 minute interval for 25 minutes thereafter. Bronchial lability was noted in 7% and 27% of the subjects in groups I and II respectively. Of all the parameters measured, FEF25-75% exhibited most striking changes when expressed as % of the baseline value.
