The "803<" Movement Kinematics Ananlysis Of Excellent Athletes Of Men’s Trampoline

This study using the method of documentary, expert interview, mathematical statistics and contrast analysis method for the trampoline man’s excellent athletes and the general players such as"803<","complete motion analysis comparison, find out the different level of athletes has a significant difference between index, probe into its essential rule, templates for trampoline offer excellent athletes in sports training and teaching, also for other trampoline technical movement training.This paper studies the main conclusion is as follows:1, Established the "803<"action each time the index of mean model.2, In the phase of take-off technology, general athletes shoulder, hip and knee joint Angle is too large, lead to the net Angle is small, lost center of gravity vertical velocity and pressure against net;In general athletes at the moment of pressure net low shoulder, hip, knee, ankle joint Angle is relatively small, did not grasp the optimal timing of stretching in time, is not conducive to stretching in the net.Lead to pressure net depth not ideal of excellent athletes.3, In the air phase, two groups of athletes of all exist in order to finish as soon as possible, at the moment with the aid of our country’s power ahead in the rotational movement, affect the beautiful sex of action; Stage in the process of swivel, players who failed to hold exhibition of body posture, appear hip flexion phenomenon;In the falling stage, some athletes in the vertical axis body has not dropped below horizontal to begin to hip flexion in advance.
