Research on infection factor on stride length of middle-distance run in midway running;

This puper analyzed the techniques of bent-leg drive mode and leg drive mode of sprint s midway running, and concluded the bent-leg drive mode was superior than leg drive mode.

With the research methods of high speed measurement and graphic analysis,the paper analyses the midway running,one-leg jump and step-jump of ten short racers on the Tartan track and the synthetic rubber track.

Influence of back step running to running technology of modern sprint;

The comparative study on where the running power of sprint comes from;

The biomechanical analysis on technique of emptying in 100 meters running;

Through teaching experiment,we studied the switch technique of midway run of 20 sprint athletes in our college for abtaining more modern theory and method of sprint training The results show that technique training of lower limbs can efficiently improve sprint technique,and advance the training effect and competition achievemen

The classical analysis in biomechanics that is the mid-way running motion of houdeng or qiudeng style sprint technology during the supporting period is the analysis in biomechanics to cushion first then to extend.

By high - speed photography and film analysis, the authors make a comparative analysis on the buffering technique of the Chinese elite 100 m runners supporting leg during the intermediate running.

By means of high-speed photography and film analysis, the mechanism produced by the changes of the velocity of the center of body mass at the supporting phase of running at full speed after start in sprinting, its dynamics and technique were discussed to provide reference for further studying and perfecting the theory of sprint as well as guiding teaching and training.
