摘要：To study the effect of airborne particulate matter pollution on the cardiopulmonary function of high-intensity training basketball players,this study selects sports university basketball players as the experimental subjects and divides them into 3 groups evenly.Group A is to participate in high-intensity training in airborne particulate pollution areas,group B is not to participate in high-intensity training in airborne particulate pollution areas,and group C is not to participate in physical exercise in pollutionfree areas.The cardiopulmonary function indicators of the three groups of athletes were tested by the Minolta Pulmonary Function Automatic Analyzer and Automatic Cardiovascular Function Tester.The HR,VC,DP,MAP,and PP of the athletes in group A were inferior to those in groups B and C (Pʽ 0.05).In the VO2max state,the VO2max,VO2max/kg, O2P and METs of the athletes in group A significantly reduced,and EQO2 and Watt indicators are significantly improved.High PM2.5 concentration will weaken the function of small airways.Under the high-intensity training,VC, ERV,FEV1.0,and MMF that reflect the large airway function of basketball players show significant negative effects before and after exercise. High PM2.5 concentration will cause the athlete's myocardial contractility,ventricular filling rate recovery ability and VO2 gas metabolism ability to decline.Airborne particulate matter pollution seriously affects the cardiopulmonary function of high-intensity training basketball players.The higher the pollution concentration,the greater the effect of the cardiopulmonary function.
