| Abstract: | By high-speed photography and analysis of flims, the author analyzes and compares the technical parameters of the support periods in the intermediate running and the second-half track running of the Chinese elite men sprinters. The results show that the factors, such as the deformation of technical actions,the prolongation of single-legged support period,the decline in frequency of steps,are the main causes that lead to the lower speed in the second-half track running. |
