摘　　要： 观察国家优秀手球运动员在递增负荷运动过程中肺通气机能变化,结果发现,运动负荷开始阶段,VERF和TV大幅增长;随着运动负荷的增加,VE、RF和TV出现相对缓慢的增长;大运动负荷期间,VE先发生上升,然后缓慢增长,RF变化与VE相似;通气阈出现在第9min左右;在开始阶段,VE/VO2随着运动负荷的增加而降低,然后,随着运动负荷增加而增加。结论:递增负荷过程中,优秀手球运动员肺通气变化过程分为快速增长阶段、缓慢增长阶段和快速增长平台期。 This experiment observed the changing feature of ventilation volume of elite handball athletes.The results show ： at the beginning stage of workload,the indexes of VE、RF and TV were in the rapid increase.With the increase of workload,the indexes of VE、RF and TV kept increased,but their growing speed was lower then the beginning stage of workload.In the bigger of workload,the changing feature were similar with the indexes of TV and RF,which it increased rapidly,and than,increased slowly.It was also the appearance of ventilation anaerobic threshold in 9th minute during the exercise.At the beginning stage of workload,VE/VO2 decreased with raising workload,and than,increased with raising workload.Conclusion：in the increased workload,ventilation volume of elite handball athletes can be divided intothree stages,which included the stage of rapid grow,the stage of slow grow,the over-respiratory stage.
