Many highly trained athletes experience exercise-induced bronchospasm (EIB): studies describing EIB in figure skaters, who may be at increased risk of EIB due to rink temperatures (7 to 10 degrees C), have not been published. We studied professionally coached figure skaters (n = 124) for EIB by spirometry at rinkside immediately before a simulated long program and at 0 to 1, 5, 10, and 15 min postexercise. Postexercise spirometry revealed the presence of EIB (a decrease from baseline in FEV1 of at least 10%) in 43 skaters, while the remainder (n = 81, control group) remained relatively stable. Pre-exercise FEV1, FVC, and FEV1/FVC ratio were not different between groups. The EIB group had significantly lower FEV1 vs baseline at each measurement following exercise: baseline, 3.08 +/- 0.13; 0 to 1 min postexercise, 2.81 +/- 0.13 (p < 0.05); 5 min postexercise, 2.77 +/- 0.14 (p < 0.05); 10 min postexercise, 2.78 +/- 0.13 (p < 0.05); 15 min postexercise, 2.78 +/- 0.13 (p < 0.05). The EIB group also had lower FVC: baseline, 3.48 +/- 0.16; 0 to 1 min postexercise, 3.16 +/- 0.15 (p < 0.05); 5 min postexercise, 3.19 +/- 0.15 (p < 0.05); 10 min postexercise, 3.27 +/- 0.16 (p < 0.05); 15 min postexercise, 3.26 +/- 0.16 (p < 0.05). Control subjects, however, experienced no decline in these variables. In conclusion, the incidence of EIB in the figure skaters measured during this investigation (43 of 124 = 35%) is greater than that of the population at large and other highly trained athletes, signifying that screening for EIB and therapeutic follow-up are reasonable considerations for participants in this sport.
许多训练有素的运动员会出现运动诱发的支气管痉挛（EIB）：尚未发表过关于花样滑冰运动员中EIB的研究，由于溜冰场温度（7至10摄氏度），他们可能患EIB的风险更高。我们通过肺量计在模拟长节目开始前及运动后0至1、5、10和15分钟在溜冰场边对专业指导的花样滑冰运动员（n = 124）进行EIB研究。运动后肺量计检查发现43名滑冰运动员存在EIB（第一秒用力呼气容积（FEV1）较基线下降至少10%），而其余运动员（n = 81，对照组）保持相对稳定。两组运动前的FEV1、用力肺活量（FVC）和FEV1/FVC比值无差异。EIB组运动后每次测量时的FEV1均显著低于基线：基线时为3.08±0.13；运动后0至1分钟为2.81±0.13（p<0.05）；运动后5分钟为2.77±0.14（p<0.05）；运动后10分钟为2.78±0.13（p<0.05）；运动后15分钟为2.78±0.13（p<0.05）。EIB组的FVC也较低：基线时为3.48±0.16；运动后0至1分钟为3.16±0.15（p<0.05）；运动后5分钟为3.19±0.15（p<0.05）；运动后10分钟为3.27±0.16（p<0.05）；运动后15分钟为3.26±0.16（p<0.05）。然而，对照组这些变量没有下降。总之，在本次调查中测量的花样滑冰运动员中EIB的发生率（124名中的43名 = 35%）高于普通人群和其他训练有素的运动员，这表明对这项运动的参与者进行EIB筛查和治疗随访是合理的考虑因素。
