| Abstract: | This paper made a comparative analysis on the two quotas resulted form the photo images of Liuxiang's fifth stride skill taken by a digital camera. The purpose was to discuss the characteristics of his skills as to provide reference for other hurdle athletes through the analysis on the kinematics quotas of the fifth stride skill on different result stage of Liu Xiang. The result indicated that in the fifth stride,the waving leg touched the soil in stillness,resist,and the time of resistance was short,the angle of touching was large,the distance between the hurdle and touching point was short. |
