This paper uses literature,video shooting method,three-dimensional video analysis,mathematical statistics and other research methods,on the 2016 "Fei Pu Lai Cup" national track and Field Championships and the National Games women's discus test matches the final scene shot by two JVC-GC-P100 high speed camera,to the final stage in the 2016 "Fei Pu Lai Cup" national track and Field Championships and the National Games women's discus test match before the final eight athletes best throwing technique characteristics as the research object,the correlation of the last exertion of eight athletes throwing technology and competition results of testing and analysis.The results showed that: 1 eight athletes accelerated stage differences only in individual indicators in the initial speed,left a moment left knee,the horizontal velocity of the left shoulder,left shoulder with greater speed that the moment of his left foot speed and left brake effect is good,the achievements will be better;left a moment the downward force is bigger the moment the athletes through the right to rotate the discus downward movement effect is obvious,the better grades you will get,and Tan Jian had left the instantaneous horizontal velocity and discus speed and several other players have different.8 athletes in the shot instantly on the right side of the shoulder joint,hip joint and the horizontal velocity of body The horizontal velocity difference is bigger,there are great differences in throwing the better grades you will get.2.eight athletes in the last exertion of the initial acceleration phase angle,left a moment left ankle angle the smaller the athletes left support this moment is better,the influence on the result of throwing the discus run better,to their lowest in an instant the greater the lead angle body chest shoulder stretch more fully to throw the results of eight athletes will be.3.the moment of left foot landing feet the smaller the distance between the legs,the smaller the angle,the more conducive to the discus throwing result above forward movement,will be better,finally forced the final acceleration phase discus the vertical displacement of up more The throwing thebetter grades you will get.4.finally accelerated with the shorter period of time,the body of explosive force is better,the results are better.The Tan Jian in the two phase of the final push for all 0.08 ratio is 1 the final stage of the discus speed rhythm grasp the good influence of eight athletes throwing.5.results main instruments shot lower speed instrument angle is too large,the low point shot,in the last exertion body and discus the various stages of the speed,angle,displacement technology and discus the time associated with the larger.It is hoped that through this study,in theory,provide the basis for the difference between the technical indexes of the final force clear athletes and the causes of throwing performance;in the practice to the coaches in the daily training and the training process control of athletes to provide reference,has practical significance for the cultivation of excellent female discus Sports reserve talents.
