摘　　要：目的:探讨大气污染对户外体育锻炼人群心肺功能的影响。方法:在空气污染区选取经常参加户外体育锻炼的人群为实验组(EG),不参加体育锻炼的健康人群为阳性对照组(CG1);在洁净区选取不参加体育锻炼的健康人群为阴性对照组(CG2)。每组15人。采用运动心肺功能检测系统对受试者不同状态心肺功能水平进行测试。结果:安静状态EG组HR显著低于CG1组和CG2组,而肺活量和舒张压显著高于CG1组和CG2组(P<0.01,P<0.05)。AT时,CG1组VO2、VO2/kg、O2P(氧脉搏)、METs(代谢当量)均显著低于CG2组(P<0.01,P<0.05)。VO2max时,EG组和CG1组VO2max、VO2max/kg、O2P、METs均显著低于CG2组(P<0.05,P<0.01)、氧通气当量显著高于CG2组(P<0.05)。结论:大气污染给人体心肺功能和有氧代谢能力均带来不良影响,且大气污染对运动人群呼吸系统的危害明显大于普通人群。Objective To understand the effects of airborne pollution on cardiopulmonary function of exercisers. Methods Selected 15 exercisers and 15 healthy workers from heavy air pollution area separately as the experimental group （EG） and the positive control group （CG1）, another 15 healthy workers from relatively less pollution area as the negative control group （CG2）. Cardiopulmonary function under different conditions was measured using the cardiopulmonary exercise testing （CPET）. Results It was shown that HR of EG was significantly lower than the that of CG1 and CG2 at rest, ventilatory capacity （VC） and diastolic pressure （DP） of EG were significantly higher than that of CG1 and CG2 （P〈0.01, P〈0.05）. When the load increased to anaerobic threshold （AT）, VO2, VO2/kg, O2P and METs of CG1 were significantly lower than that of CG2 （P〈0.05, P〈0.01）. When the load increased to VO2max, the results of VO2max, VO2max/kg, O2P and METs of EG and CG1 were significantly lower than that of CG2 （P〈0.05, P〈0.01）, and EQO2 was significantly higher than that of CG2 （P〈0.05）. Conclusion It was concluded that airborne pollution seriously affects the cardiopulmonary function and aerobic capacity. And these adverse effects on exercisers could be more obvious than on the healthy people.
