摘　　要：该文以2018世界竞走团体锦标赛男子20km竞走前三名运动员的速度变化为研究对象,采用了文献资料法、对比分析法、数理统计法,对2018世界团体锦标赛全程20km的前半程(前5圈)和后半程(后5圈)速度变化进行了对比分析。得出了我国运动员王凯华具有前半程速度相对于其他2名运动员速度较快、较稳的优势,但后半程的冲刺速度表现不如冠军日本运动员池田向希。针对所得结论提出以下建议:王凯华在日后的训练中需要加强冲刺阶段的速度、耐力训练及体力的合理分配,保持前后半程相对合理的平均速度,提高后半程速度。This article takes the speed changes of the top three athletes in the men's 20 km race walking at the 2018 World Race Walking Team Championships as the research object.It uses the method of literature data,comparative analysis,and mathematical statistics to analyze the first half of the 20 km course(first 5 laps)And the latter half(the last 5 laps)speed changes were compared and analyzed.It is concluded that Chinese athlete Wang Kaihua's speed in the first half is faster and more stable than the other two athletes,but the sprint speed in the second half is not as fast as the sprint speed of champion Japanese athlete Ikeda Muko.According to the conclusions obtained,the following suggestions are put forward:Wang Kaihua needs to strengthen the speed,endurance training and the reasonable distribution of physical strength in the sprint phase in future training,and maintain a relatively reasonable average speed in the front and rear half,and increase the speed in the second half.
