摘要：AbstractThe aim of this study was investigate the prevalence of exercise-induced bronchospasm in elite athletes. Exercise-induced bronchospasm was defined as at decreasing equal or more than 10% in FEV1, decreasing equal or more than 15% in FEF25-75% and decreasing equal or more than 25% in PEFR. The statistical society includes all the professional basketball players in 8 teams of super league from Iran, Khuzestan province. 20 players are selected randomly as the sample group. Before and after RAST anaerobic test were measured some of pulmonary indexes include FEV1, PEFR and FEF25-75%. all statistical analysis was accomplished by using Spss (V 16). All collected data were assessed by dependent T-test. Statistical significant was conferred at p=0.05. The findings research showed that In the three measured indexes a were observed meaningfully and paralleled decrease of 12.60%, 7.8%, and 5.41% relatively in FEV1, PEFR and FEF25-75% (P<0.05). According to the definition of exercise-induced bronchospasm we can recognize that the level of exercise-induced bronchospasm Prevalence in the samples only by a sign (the average decrease of 19% of FEV1 in 60% of the samples). In other indicators, the maximum decrease is defined as less than the limit of the exercise-induced bronchospasm (the maximum decrease of 9.87% in PEFR and the maximum decrease of 6.83% in FEF25-75%).
