A Comparative Analysis of the Horizontal Velocity Changes in the Course of Approach and Take-off for Chinese and Foreign Elite Female Triple Jumpers;

Velocity characteristics of last two steps in approach and takeoff of elite female triple jumpers in China;

Research on approach speed and rhythm of some Chinese elite female triple jumpers;

Analysis of factors influencing the accuracy of run-up in broad jump;

This article analyses changing of length of the last two steps in run up and its effect on the result of broad jump biodynamically,thus determining the proper range of changing the last two steps in broad jump.

The result shows that the technique of run up and takeoff and specific performance for experimental class is better than ordinary class.

This paper analyzes and studies the random test data, which 67 students of PE department got, and find out the principal factors that affect the accuracy of long jump run up so as to improve the teaching methods and the teaching quality.

Exploration of improving accuracy of running in long-jump;

Based on the present status of long jump and documental data and mathematical statistics,this paper analyzes the running speed,rhythm,use rate of speed and landing,cushioning,legging,covering of gravity move in the jump course,so as to find out some factors affecting the result of long jump.

Using the document research method, analyse and study the vision effection on fosbury flop asistant running for the athlete how to control the body postures.

A comparison between the elite Chinese and foreign male jumpers approach run and jumping techniques;

According to technical principles of volleyball spikes,vision marks were used to give hint to,to induce and to reinforce vision of approach run steps,gravity locus of approach run, opportunity of swing arm and point of hitting.
