The Analysis On Technical Time Characteristic And Competiti Veapacity Of Liu Xiang, 110m Hurdles Champion In The 28～(th) Olympic Game

' This research object focus on the 110 meters hurdle technology of our country outstanding athlete Liu Xiang , gold medal winner of 110 meters hurdle of the man in the Athens Olympic Games. Analysis video materials of Liu Xiang 110 meters hurdle at 28th Olympic Games (Athens) which obtains from the CCTV channel five, and uses the information technology method analysis the 110 meters hurdle technical parameters of Liu through the video materials and compare it with the technical parameter of the modern age hurdle athletes according to the technical principle requests, As well as domestic and foreign top athlete of a hurdle, comprehensive compare and analysis 3 steps of the time and the speed, and the technical parameter. The goal of study is the characteristic target change of Liu of a 110 meters hurdle, try to explore the technical characteristic and the rule of Liu in a 110 meters hurdle, try to provide some help to the technical improvement, the training and the competition of Liu. This research shows:1. The period from the 2001-2004 of preparation for 28th of Olympic Games, The technology of Liu Xiang had the rapid program. Compare with the world top athlete Jackson, the study also shows Liu Xiang's quickest hurdle speed faster than Jackson, The entire speed perturbation is big; the quickest hurdles speed appears foreword 3rd hurdle postpones to the 6th hurdle.2. In Athens Olympic Games, the pace ability of Liu Xiang's 3-step between hurdles, the end point sprint ability is much better than the other world top athletes, surpassed the average highest hurdle speed of the top 8 athletes in 2003 the French Paris world championships in athletics, Maintains high speed passed the hurdle also same as the other top athletes, Liu already has the ability of defeating the world top 110 meters hurdle athletes. ,3. Study from the single technical, Liu's speed of the hurdle attacking is very quick; the strut time is short, while the speed of clearance is not fast. Hurdle clearance technique also has the flaw.4. The time of Liu Xiang's 3-step between hurdles are short, technologies of the between hurdle step are good; the time of hurdles assignment are appropriate, the hurdle cycle technology is reasonable.5. When the waving leg grounded the land, the angle of the leg is larger, the distance between the hurdles and landing point was short .and the support time was short, Is advantageous the speed display, Namely the technology of linking up the hurdle cycle to be good.6. Liu xiang has already formed the technical characteristic of his own 110 meters hurdle, and has achieved the level of world top 110 meters hurdle athletes.7. Liu Xiang displayed the strong participative ability at the Athens Olympic Games, but the physical strength assigns is not very reasonable.
