Analysis on "Utilization Rate of Approach Speed" of Chinese Elite Long Jumpers

Biomechanical research on the conversion ratio of approach speed of high jump;

This paper intends to discuss the basic way of improving the triple jump result by analyzing the approach speed and the level speed of triple jump.

Support strength and run-up speed of triple jump;

Through analysing the run-up speed and the results of some excellent sportsmen,a theory is advanced that the running speed is a decisive factor for long jump.

Some methods such as literature consultation,mathematical statistics and comparative analysis were employed to study parameters,for example,run-up speed,horizontal speed,vertical velocity and jumping angle in jumping of famous male long-jump athletes at home and abroad.

This paper analyzes the run up speed and the take off technique of two famous American long jumpers,who broke the world record in the male long jump,and points out the characteristics of the long jump technique in the modern world as well as their impacts on improving the performances according to the latest sports information of the world.

The results show that in modern triple jump run up speed not only has decisive ef-fect to improving sport result, but also is one of the main factors which impact athlete taking whichtechnical types.

The findings indicate that:firstly,along with quickening the run up speed gradually,the received impact workload of jumpers leg muscles augments.
