摘　　要：目的:探讨脉冲震荡技术(IOS)气道阻力测定对运动员肺功能异常的诊断价值。方法:对中国国家队398名运动员进行常规肺功能检查并采用脉冲震荡技术(IOS)进行气道阻力测定。按照常规肺功能测试结果将受试运动员分为肺功能正常组、阻塞性通气功能障碍组及小气道功能减弱组。结果:(1)IOS气道阻力参数气道总阻抗(Z5)、气道总粘性阻力(R5)、近端气道粘性阻力(R20)与慢肺活量(VC)、一秒用力肺活量(FEV1)、一秒率(FEV1/FVC%)、25%肺活量时的最大呼气流量(FEF75%)、50%肺活量时的最大呼气流量(FEF50%)均存在负相关(P<0.05);周边弹性阻力(X5)与VC、FEV1、FEF50%、FEF75%呈正相关(P<0.05)。(2)与肺功能正常组运动员比较,阻塞性通气功能障碍组及小气道功能减弱组的Z5、R5、R20均显著高于肺功能正常组(P<0.05),X5%显著低于肺功能正常组(P<0.05)。结论:脉冲振荡气道阻力测定可以作为运动员肺功能检测和治疗监测的有效方法。肺功能异常运动员总气道阻力增高,主要表现为中心气道粘性阻力增高同时伴有肺顺应性下降。Objective To investigate the diagnostic value of the impulse oscillation system （IOS） in determining pulmonary function of elite athletes. Methods The pulmonary functions of 398 Chinese professional athletes were measured at rest with JAEGER MasterScreen,including airway total impedance （Z5）, airway total viscosity resistance （R5）, proximal airway total viscosity resistance （R20）, 1-second forced vital capacity（FEV1）,slow vital capacity（VC） and fast vital capacity（FVC）,maximal expiratory flow at 25% of vital capacity（FEF75%）, maximal expiratory flow at 50% of vital eapacity（FEFS0%）, and peripheral elastic resistance （XS）. The results were classified as normal pulmonary function,obstructive ventilation dysfunction and weakened function of small airway. Results（ 1 ）The ZS, RS, R20 were negatively corrected with VC ,FEV1, FEV1/FVC% ,FEF75% ,and FEFS0% （P 〈 0.05）. X5 was positively corrected with VC,FEV1 ,FEFS0% ,and FEF75% （P 〈 0.05）. （2）The ZS, R5 and R20 of the athletes with abnormal lung function were higher than the healthy athletes （P 〈 0.05）. Percentage of X5 of the athletes with abnormal lung function was lower than the healthy athletes （P 〈 0.05）. Conclusions The impulse oscillation system deployed in this study can effectively determine pulmonary functions of athletes.
