A Kinesiological Analysis Of The Hurdling Techniques Of China's 110m Hurdlers Liu Xiang And Shi Dongpeng

With the development of field facilities, the innovations in techniques and the perfection in theories, hurdling achievement is moving toward a more inspiring end. Liu Xiang's excellent performances at Olympic Games and later in Laudsanne show that China has among other Asian countries taken the first place to lead the world in the field of 110m hurdles.Based on the current research fruits and facilitated by such approaches as literature-searching, photographing, picture-analyzing, statistics and comparative analysis, the thesis focuses on the two top players Liu Xiang and Shi Dongpeng of China, gives a detailed and deepened research of their hurdling techniques and tries to offer a theoretical reference for China's hurdling players.First, Researching resultsOne. There is still a gap between Liu Xiang and Shi Dongpeng and the world's senior players in terms of racing without barrier. Liu Xiang does better, in speed-raising at the moment of launching out and in hurding under the state of speed-raising, than Shi Dongpeng; but they both have been among the top players in terms of their running speed after the 10^th hurdle.Two. Liu Xiang reaches his first speed peak quicker than the other players by two hurdles. Specifically, he offers an earlier hurdling cycle and a shorter distance from the starting point. As for stride frequency between the hurdles, the two players enjoy an ability to beat the world's other top players. Shi Dongpeng completes the first nine hurdles in less time than Liu Xiang and he has an excellent rhythm between the hurdles.Three. Liu Xiang has a wider angle before crossing and a less wide one upon landing; a strong consciousness of conquering hurdling, a greater speed of launching first crossing, a short time period of support; yet a relatively long distance to launch the first crossing.Four. As for the angle between the two legs, Liu Xiang and Shi Dongpeng enjoy a more pleasing one than their rivals, but their respective body angles of bending forward when in the air are not so good. When we refer to the angle of their barycentre moved up, Shi Dongpeng has a more welcome one.Five. Liu Xiang, compared with Shi Dongpeng, keeps himself in a shorter time and moves a shorter distance in the air; and when in the air Liu's barycentre goes a lager range than Shi, which means that Shi is more able to keep balance in the air.Six. Liu Xiang, when finishing a hurdle, has a lager landing angle, a short distance, a higher barycentre-supported position, a shorter support time; this benefits a good speed between the hurdles. Shi Dongpeng enjoys a longer landing distance, while his body keeps a relatively favorable landing balance.Second, According to the above-mentioned results, I put forward some suggestions here.One. The top priority is to quicken the running speed of our players.Two. The top Chinese players keep a better running speed between the hurdles than their foreign rivals but the maximum is still to be raised.Three. Compared with their foreign rivals, Chinese hurdlers enjoy a smaller number of hurdles at the maxim speed; they need to improve their endurance.Four. Among the other approaches, improving striding technique and shortening crossing time are workable to Chinese players.Five. We need the awareness to enlarge the angle of bending forward, to lessen the angle and height of the barycentre in the air ; at the same time to realize an active landing, shorten the time in the air and cut the stride width during crossing.Six. It is suggested to control the rhythm of crossing, to reduce the time variance between hurdles and to push forward moving techniques.
