Analysis of the association between exercise induced bronchospasm, cardiorespiratory fitness, and physical activity levels of adolescents

ABSTRACT This study aims to verify the association between exercise-induced bronchospasm (EIB), cardiorespiratory fitness, and physical activity levels in adolescents. To do so, we evaluated 202 healthy adolescents aged from 13 18 years, out of which 94 (46.5%) were females 108 (53.5%) males. Participants performed a bronchial challenge test treadmill (Master Super ATL, Inbramed®) evaluate hyper-responsiveness; spirometric (Microquark, Cosmed®) lung function; answered Baecke’s Questionnaire Habitual Physical Activity; progressive aerobic cardiovascular endurance run test. Data analyzed using Spearman’s correlation, chi-square test, odds ratio. The significance level adopted was p<0.05. No statistically significant correlations found decrease forced expiratory volume first second (FEV1), levels. Likewise, chi-squared revealed no differences classifications fitness (low or adequate) EIB (presence absence) (χ2=0.155; p=0.694). Finally, ratio showed increased chances presence participants who presented low (OR=1.130; CI: 0.616-2.073). We concluded that are not associated with FEV1 there is relation classification
