Kinematical Analysis On The Chen Caihong Of Shanxi's Excellent Female Javelin Thrower In The Phase Of Release

In this article, Shanxi elite female thrower javelin Chen Caihong as the research object, use dartfish analysis software and testing of the phase of release Chen Caihong javelin technical analysis of the many factors influencing, in order to indentify athletes'technical problems, make the right diagnosis ,and rationalize the observations and recommendations, provide for training and using for reference to its training methods and means much more materialization, and in a technical understanding of javelin and we know any more, the teaching and training and practical significance, and promoting female sport Shanxi javelin of sustainable development.Through analysis of the results of research, by the following major conclusions:1. Chen Caihong right foot on a moment to moment after his body tilts changes range of relatively large, the bill supports the extension of time, to some extent, affect the continuity of action, and shall suffer the effects of the final effect.2. Chen Caihong cross stride in his right foot with his right moment in fulfils the greatest fraction of the buffer cushion, and right knee in a large and right leg during the good results. The right to individual load capacity is relatively weak of strong and had to sell a large margin to reduce the cushion to withstand the heavy load to avoid even the standard rate, the follow-up action to ensure the successful completion.3. Chen Caihong from his left foot on a moment to moment, his left knee corner javelin wants to have reduced to 22 degrees, in his leg out eleven degrees and an amplitude of 33 degrees, it is obvious drive out of range, drive out of technology to be further improved.4. Chen Caihong cross stride right foot with your right elbow, 149 degrees of the moment when my body move your right elbow supported by a moment of degrees, with 145 his right elbow 133 degrees angle fraction of the last of the throwing process of throwing arm not be extended, so it is difficult to make full use of the arm length, but also shorten the hard work.5. Chen Caihong the last step length is relatively small, should strengthen the practice in their power, properly intensifying the final step paces.
