Exercise Induced Bronchoconstriction (EIB) prevalence in cold weather athletes is high. Currently, no standardized cold air exercise provocation test exists. Thus we aimed to determine EIB prevalence using a Cold Air Test (CAT; 5 km outdoor running; -15 °C) compared to the most common EIB screen the Eucapnic Voluntary Hyperpnea (EVH) test in cold weather athletes. Sixteen (9 male; 20-35 years old) cold weather athletes completed EVH 72 h before CAT. Spirometry, Fractional Expired Nitric Oxide (FENO), respiratory symptoms were measured and atopy status was determined. Five and 7 participants were EIB + on the EVH and CAT, respectively. Level of agreement was 50% between tests. FEV recovery was significantly prolonged and Peak Expiratory Flow was decreased after CAT compared to EVH. Predictive characteristics of EIB + included FENO >12 ppb, FEV/FVC ratio (<0.75) and BMI < 20. EVH does not always reflect EIB triggered by cold weather exercise. More research is required to understand the best EIB screens for cold weather athletes.
在寒冷天气下运动的运动员中，运动诱发的支气管收缩（EIB）的患病率很高。目前，尚无标准化的冷空气运动激发试验。因此，我们旨在通过冷空气测试（CAT；户外 5 公里跑步；-15°C）来确定 EIB 的患病率，与最常见的寒冷天气下运动的 EIB 筛查试验——Eucapnic 自愿过度通气（EVH）试验进行比较。16 名（9 名男性；20-35 岁）寒冷天气下的运动员在 CAT 前 72 小时完成 EVH。测量了肺活量、呼出气中一氧化氮分数（FENO）、呼吸症状，并确定了特应性状态。EVH 和 CAT 上分别有 5 名和 7 名参与者为 EIB+。两种试验的一致性为 50%。与 EVH 相比，CAT 后 FEV 恢复明显延长，呼气峰值流量降低。EIB+的预测特征包括 FENO>12 ppb、FEV/FVC 比值（<0.75）和 BMI<20。EVH 并不总是反映由寒冷天气运动引起的 EIB。需要进一步研究以了解寒冷天气下运动的最佳 EIB 筛查试验。
