HYPOTHESES: 1) a minimum AHR prevalence of 20% would be revealed in a group of high school athletes; 2) demographic data would predict AHR; 3) AHR-positive athletes would preferentially choose low ventilation sports. Eucapnic voluntary hyperpnea (EVH) was used to test for AHR in 23% of all athletes (79 of 343) of a midwestern high school. The AHR was defined by at least a 10%, 20%, or 25% decline in FEV1, FEF25-75, or PEFR at 1, 5, 10, or 15-min post-EVH, respectively.
RESULTS: 30 of 79 (38%) tested positive for AHR; demographic data tended to predict AHR, as correlations between the total number of years exercised with the greatest decline in FEV1 and the total number of days exercised with the greatest decline in FEV1 following the EVH challenge tended to be significant (r = 0.354; p = 0.055 and r=0.314; p = 0.091, respectively); and 69% of AHR-positive students played only low ventilation sports.
CONCLUSION: AHR prevalence was 38% in athletes of a midwestern high school; demographic data tended to predict AHR; those with AHR preferentially play low ventilation sports.
