An Analysis On The Main Characteristic Of Kinematics And Dynamics Of Chinese Excellent Sprinter Zhang Pei Meng’s Mid-way Running Technique

The development from China’s sprint events and achievements, compared with the world’s top level there is a big gap. In recent years, to increase the input of the General Administration of sport center, line coach, research workers,, considerable attention on dash project, especially the theory of scientific research base of sprint techniques on sprint training and competition of sports biomechanics as to. The present study for domestic sprint techniques are much, most of these studies were selected in a game or a few games, compared with the kinematic analysis of athletes single speed or angle parameters, and can not meet the need of comprehensive kinematics analysis and Research on the dash technique. In view of this situation, by consulting literature and with coach Zhang Peimeng Li Qing and frontline coach communication, agree, running technique is an important part of the entire dash technology, its task is to continue to develop and maintain high speed long distance continuous run ability, how to innovate the sprint training mode, sprint has become the key to solve the development of China’s track and field sports, on the way to the outstanding sprinter Zhang Peimeng running technique for diagnosis and analysis, and has important theoretical significance and practical value. In this paper, on the basis of previous research results, the use of high speed image analysis on the way of Chinese elite sprinter Zhang Peimeng ran technology in-depth analysis, so as to find out the technical characteristics of Zhang Peimeng run stage in the way and law, the difference between to find a Peimeng within 10 seconds and foreign athletes, improve the overall level of Zhang Peimeng on the way of our country sprinters technology, provide theoretical basis and practical reference for China’s sprint athletes and coaches to master high level technical training methods, promote the continuous development of China’s athletes. This paper comes to the following conclusions:1 Zhang Peimeng running on stage show high frequency technology stride characteristics of relatively small,100 meters by 47 step completed, hang time step in the account for a large proportion, there on the way to run the speed rhythm to maintain absolute speed ability is weak, the characteristics of velocity is obvious and so late.2 Zhang Peimeng on the way running buffer and the thrust of stopping, starting point is the center of gravity of the body moves through the supporting vertical buffer parts, the body center of gravity fulcrum line and ground direction angle of about 74.4 degrees position.3 Zhang Peimeng upper limb movement strength was weak, arms swinging back and forth frequency fast but the magnitude is small, not enough to relax shoulder on the run, shoulder flexibility needs to be improved.4 Zhang Peimeng limb motion thigh swinging under the pressure of pawing with horizontal velocity angle is better, but the hip and ankle strength weak, supporting the existence and back pedaling moment ago support distance near, extends the hip range is small, the pedal angle after a big angle.And the emphasis placed before grilled the frequency of driving strength is insufficient, cause back pedaling is not sufficient, influence to maintain the level of speed, resulting in relatively long flight time.
