摘　　要：通过二维录像解析和足底压力分布实验测试,对竞走项目运动员最大速度能力和足底压力分布特征进行相关的基础研究,以获得竞走项目运动员在特定的技术规则规定下,世界级优秀竞走运动员的极限最大速度能力、关键运动学参数和足底压力分布特征参数情况,并对这些运动学和动力学参数进行了相关分析。This paper made basic investigation on the maximum speed ability of race walking and the distribution of plantar pressure by using two--dimension video--tape analysis and plantar pressure test system. The purpose was to provide the limited velocity and the key kinematic parameters and the character of plantar pressure c of the world--class race walking athlete under the special require of the race walking rule. The research subject was twelve Chinese world --class elite male and female race walking athletes, whose specific sport were the 20km race walking event. The main result of this paper provided the relevant kinematic and dynamic pa rameters of Chinese world-class elite race walking athlete. The kinematic parameters included the maximum speed and the maximum stride and the height wave of body center gravity and the period of one step and the time of take-off, support and straight leg and so on. The dynam ic parameters included the maximum force of plantar and the maximum pressure of plantar and the curve character of plantar force and the distribution types of plantar pressure and so on. This paper presented correlative discussion and analysis of those parameters. It could induce some corresponding conclusions on the base of these research result and analysis and discussion.
