Technology relatively complicated many throw projects javelin throw, its intact technologies through holding a javelin the run-up win most heavy speed, Join and throw step and get momentums, act on the end of the breaking out type the axis of ordinates of the javelin hard, Make javelin at suitable angle, throw and produce at shoulder javelin. Modern javelin throw technology pays attention to the speed with the technology of linking up that is exerted oneself further. Originally studying will carry on comparatively overall analysis to javelin throw technology from the kinematics respect, Have proposed influencing the trends to surmount the relevant index of the apparatus , and has carried on the ration or qualitative analysis to the main factor and interreaction among them . Utilize three-dimension make a video recording to of our country and outstanding man throw means steps of stage sell, Comparatively identical with the sportsman’s actual, Make the coach and sportsman can understand the interreaction between every factor impact on achievement and them comparatively overallly, accurately , Offer science, rational method for analysing javelin throw technology. Analyse and indicate of our country outstanding sportsmen pedal ground put not good enough actively, Incline angle little to change range, level draw guide relatively heavy fluctuation angle, lead to the fact centre of body weight drops by horizontal speeds after the truck, The link is in the high speed sport and the combination which surmounts the apparatus is also unsatisfactory, the trends surmount the apparatus insufficiently.
Keywords: The javelin Step alternately Exert oneself at last The trends surmount the apparatus Three-dimensional kinematics is studied
