Kinematical Analysis About The Final Stages Of Exertion Of Main Technical Characteristics Of Movement On Male Javelin Thrower Hu Hailong In Shaanxi Province

In recent ten years great achievement on track and field has been made by our athletes, especially in women's term, but the men's ability hasn't made an obvious improvement and capability of men's javelin throwers is always stagnant, or even falls back. It is very difficult for the male javelin throwers to surpass 80 meters, which should be given close attention by the coaches, athletes, researchers and leaders. We should try our best to change this unsatisfied situation. The factors are as follows: on one hand, the lagging technology, particularly the last spurt. Many essays should focus on this problem in order that all the abilities of javelin trainers can be improved and athletes'potential can be explored. Papers about personality of new born javelin throwers should be encouraged and promoted.Selected "on the Shaanxi Provincial Elite Male Hu Hailong Final Exertion The main technical characteristics of movement kinematics analysis" as the subject, through the men's javelin thrower Hu Hailong Shaanxi Province, the last force in several important sectors of technical analysis and my videos former men's javelin champion Zhang Lianbiao and Li Rongxiang marked the last effort techniques in several important sectors of comparative analysis of video resolution, thereby Shaanxi Male Javelin Hu Hailong advantages and disadvantages of a better understanding of technology. Trying to find its technology advantages and disadvantages of the final stages of exertion, for the future development of scientific exercise training program; specific sports training mission; select sports training methods; control exercise training intensity to provide a theoretical basis.Result shows:Hu Hailong last step the right foot after landing when the trunk angle change is small, the horizontal line to reduce the loss of braking and speed requirements; in the final stage of force, the right foot to right knee forward to the buffer when the maximum bending too long, right foot Push body inertia forward setting stage after too long a duration, the intensity of his right leg kicking is not enough enthusiasm left leg forward interpolation is not high; the final stage of the right foot forward in an instant force, inadequate strength of the right leg stomp, right foot stomp too early; and our elite athletes in comparison, the rate of decline in the rate is too large, low speed Javelin Throw, Hu Hailong throwing the javelin in the cross step right foot forward to the time when the body horizontal velocity has reached the national top level athletes, Hu Hailong landed in the left foot, left leg is not active under the insert action, not able to insert the next fastest speed to low, flat, fast action essentials to complete; the left foot forward to the support of left knee joint angle is very good; force in the final stage of the ground to the left knee, left foot maximum bending angle is too small when the knee is not conducive to the leg muscles, the horizontal speed of the transformation; left foot when the knee angle of the ground and the maximum bending angle is better, in the Javelin Throw too large when the angle of the knee, Javelin Throw longer; right shoulder strap ligament less flexibility in the final stage of force beyond the equipment to do the action is not sufficient, the final distance is not enough hard work; in the final stage of the right arm force extension degree is too small, not enough body beyond the range of instruments; his right arm in the throwing arm from right moment Javelin Throw sinking, the last step of the step frequency is too small.
