In order to apply it scientifically on athletic training in practice for professionals engaged in athletic training and students majored in physical education, Using the method of summarizing literature and professional logic analyses, this article analyzes and discusses Super-equal-length exercises physiological mechanism and exercise effect.

With the research methods of the experiments,documents and mathematical statistics,using super long muscular strength practice as teaching method,through contrasting the comparative group to experimental group,after seven-week training,the author found super long muscular strength practice could effectively improve technological movement,sport performance and physique of women s shot.

A new training carrying the weight vibration exercise and the plyometric depth jumping exercise were studied by contrast experiment at Kistler three dimensious plate.

Physiological Analysis of Plyometrics;

Documents and analysis study shows that the effective method of power training should have an accelerative characteristic throughout a muscle concentric contract movement And plyometrics training has the characteristic Furthermore,the most effective power training ought to be considered a perfect combination between traditional barbell weight training and plyometric

The application of how to use on arms and legs train is also introduced,which can be as one of the theoretic evidence of ploymetric training.

By means of a review of the researches about ploymetric contract principle,this paper discovered the particularity of ploymetric training modelshould be decided by the difference of objects strength basis, training level,body weight, training load.
