On velocity rhythm in 100m sprint from the perspective of energetics fatigue of nerve center;

Integrating theory with practice, the paper has analysed the ability of acceleration of 100m sprint all sidedly.

The paper analyzed the segmentation performance of the world-top 100m runners and constituted the 100m specific speed model.

It is a relation of unite of opposites between maximum speed and keeping distance in 100m running.

The author analyzed the technique of world elite men s 100m running by using biomechanics in order to find the main factors that influence to it.

In order to explore the issue of the change of full-length speed and gait of 100m running and its manual control in the training,the authors try to analyze current researches by longitudinal and horizontal comparative analysis and then further discuss how these theories can be used in practice so as to discover the law and characteristics of the speed rhythm of 100m 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.

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;
