Activity Patterns of Shoulder Major Muscles in Different Abduction Angles;

In view of the characteristic of the teenage high jumpers,by analysis of the skill and the muscle group which join in the high jumping,the article proposes the strength training of teenage high jumpers by the supplementary training,common strength support training and special strength support training method,and puts forward some problems that need to pay attention to in the training.

Comparative Study on Form and Force of Knee Joints Flexors and Extensors of the Long Jumpers;

This paper examined and compared the performance of hip-joint muscles from 53 elite speed skating athletes,using CYBEX6000,which included the peak torque,average power,total work as well as flexor/extensor(%) of hip-joint flexors and extensors.

By using CYBEX6000,the paper carries a comparative research on 53 speed skating elites(30 male and 23 female) to test the peak torque,total and average power,as well as the ratio of flexors and extensors of knee muscles.

To explore the rules of muscles change to different training level sprinters,we can illustrate the character and intrinsic relationship of relative muscles work mechanism,clarify the rational proportion of muscle strength.
