The Kinematic Analysis Of China's Outstanding Athletes Woman Hammer Throwing Technology

Chinese women's hammer throw performance largest in the world, women's hammer throw achievements relatively rapid growth,but with the world's outstanding women's hammer throw is still a certain gap between the domestic and the women's hammer throw on the existence of the following deficiencies:1,China's outstanding woman athlete of less hammer;2,mostly concentrated in the study of all athletes with a game between the horizontal comparative analysis,3 of the individual elite athletes and abroad between the comparative analysis.Overall,the lack of elite female athletes hammer longitudinal comparative analysis,from a technical point of view,the vertical on our outstanding athletes woman hammer technical analysis and research,and explore various parameters and technical indicators money changes,summed up China's Three women's hammer throw performance of changes in the performance of the various technical aspects of the changing of the parameters and characteristics to their hammer throwing style and the technical advantages,as well as the weak link in China's scientific training of the women's hammer provide theoretical reference.Conclusion:1.Compares the overseas outstanding female hammer athlete,our country outstanding female hammer athlete hammer throw technology's revolving rhythm is not very reasonable,mainly displays in revolving first is too quick,thus causes the third,fourth revolving acceleration rhythm not to be obvious.2.Compare the overseas contestant,our country outstanding female hammer athlete hammer throw technology's final forcibly stage existence obvious technical question,displays to make an effort the stage time to be short finally,is not ideal to the hammer acceleration effect.3.Speaking of the hammer various stage speed parameter,revolving fourth and makes an effort the stage not to be unstable finally to the hammer acceleration effect,is not ideal,the primary cause lies in the above stage list,the double support time distribution to be unreasonable,the radius of turn is unstable creates.4.Speaking of the shoulder hip angle,the hip knee angle,our country outstanding female hammer athlete the maximum value average is oversized in the revolving process,indicated that the upper limb,the torso turn tight the degree to be big,with the high level athlete high velocity, the quick rhythm,surmounts the degree small characteristic not symbol which now the instrument and the torso twist.Recommendations:1.The control warm-up swing stage hammer's operating speed,takes seriously and strengthens the warm-up swing stage with to revolve the first engagement,this is very important to the successor revolving rhythm.2.Guaranteed that the first three reasonable revolving rhythm in the foundation,in the training takes seriously to enhance the athlete in fourth and makes an effort finally the stage to the hammer control and the hammer movement stability,stressed that upper limb's extension, enhances to the hammer acceleration effect.3.Changes large scale,slow rhythm revolving to throw the idea, strengthens in the hammer training to revolve the rhythm and the speed practice...
