Subjects
All subjects (n = 370) were developmental or elite athletes between the ages of 16 years and 37 years who volunteered to undergo routine evaluation for asthma and/or EIB at the US Olympic Training Center in Lake Placid, NY. No significant difference in study group gender proportion existed (174 female and 196 male subjects). Of the 370 athletes, 169 trained and competed outdoors and 201 trained and competed indoors. The vast majority of the subjects (n = 318) competed in winter sports, 49
Results
Thirty percent (n = 111; 58 female and 53 male subjects) of the 370 athletes were identified as EIB + by a ≥ 10% postexercise fall in FEV1 (Table 1). The 111 EIB + athletes demonstrated postexercise falls in FEV1 of 18.6 ± 10.0% (mean ± SD), compared to 3.1 ± 4.6% for the 259 EIB − athletes.
Approximately 5% of the 370 athletes (n = 19; 18 female and 1 male subjects) demonstrated IS during and/or immediately after exercise; 53% of the 19 IS + athletes (n = 10) presented comorbid EIB. The 19.4 ±
Discussion
The purpose of this study was to report the prevalence of IS in elite athletes. To our knowledge, this report is the first to provide a comprehensive estimate of IS for an athlete population. Overall prevalence of IS in our cohort of developmental and elite athletes was 5.1%; the 8.3% prevalence in the outdoor athlete group was significantly higher than the 2.5% observed in the indoor athlete group (p < 0.05). The prevalence of IS in the athlete population and within the outdoor subpopulation
