| Abstract: | 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 un-der 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 discus-sion. |
