Research Upon Time Characters Of Liuxiang’s110m Hurdle

In this study, the use of information technology, combined with literature data,comparative analysis and mathematical statistics, China’s outstanding110metershurdler Liu Xiang retire because of injury in2001-2012the Lun Dunao On key gamebetween the video complete technical analysis. The selected game video video to winthe2004Athens Olympic Games Liu Xiang12.91s,2006Lausanne, SwitzerlandGrand Prix12.88s break the world record video, video2010Guangzhou AsianGames13.09s win (known as the real return of the king of the game, as well as its2008after injury bests Step8attack first column technology),15May2011ShanghaiAthletics Golden League won13.07(new technology seven-step attack the firstcolumn of the first show), May20126Kawasaki Station13.09s win,19May2012Shanghai12.97s win and3June2012the Eugene station12.87s win (super speed);Cuba’s wearing a dragon Roberts on13June2008in0.01s advantage to break LiuXiang12.88s record video; U.S. champion David Oliver on16July2010in Paris,France station ran12.89s game video. The captured video data using informationtechnology-based approach, respectively, to obtain Liu Xiang, the technicalparameters of the Dragon-Roberts and David-Oliver key game. Including theirstarting reaction start to the first column, the first three columns,3-10bar, sprint timeparameters to conduct a comprehensive comparative analysis on these five areas. LiuXiang new technology before and after the five stages of change, as well as wearing adragon with the same technology in the first column of the seven-step attack "-Roberts, David-Oliver comparative analysis to identify where the gaps, as well asthe future of China110meters hurdles in the future development of the technologyand sports selection for reference. The study results showed that:1. Liu Xiang, the first column of attack8steps achieved under12.88s technicalachievements, has been difficult to further breakthroughs. Because of its start to thefirst column and the column between1-2acceleration, speed to maintain4-5bar,which is also constrained Liu Xiang three biggest obstacle to further breakthroughs. Athletes should be balanced in order to improve the development of110-meterhurdles results.2. The new attack in the change column technology, Liu Xiang made thestarting reaction time12.87s0.131s, which is better than the previous12.88s reactiontime of start of0.108s more0.023s, this situation may exist two reasons, one aspect isthe increase in physiological age, on the other hand the new technology immaturityconcerns before starting points more. While its strengths has always been the end ofsprint capacity than previous10.502m/s down to10.249m/s, the speed dropped2.4%. Another new technology, the Liu Xiang over the next column2to column3onthe speed of convergence is relatively weak compared to the world’s top players. Italso provides training for its future parameter data.3. In a "seven-step attack first column of the" new technology, Liu Xiang, thetime parameters of the first three columns slightly stronger than the previous"eight-step attack first column," the old technology, and with the world’s best playersto shorten Dai Long-Romania the gap between the first three columns in Perth. Butfrom the start to the first column on the technical parameters of the same before the"eight-step attack first column technology," but there is a slight decrease, while in thebar after the process of convergence between the speed and the sprint stages to befurther improved to strengthen. Seven-step attack first column technology immaturitythat has a great relationship.4. Liu Xiang integrated physiological age and new technology achievementsunder and wearing dragon-Roberts, David-Oliver typical example, the first columnof the seven-step attack technology is likely to become the next world’s best110-meter hurdles hurdler preferred mode of.5. Men’s110meters hurdles sport increasingly intense competition, the athletesin the future should be based on the specific circumstances of the game to makecorresponding spot tactical adjustments.Based on the findings, some reasonable suggestions were:1.110m high column is a technology to be extremely difficult to master thesport. Throughout every stage of restricting athletes toward the final grade. Thereforeathletes to maintain their advantage on the premise, according to their own lack of targeted training, in order to comprehensively improved.2. the first column of the new seven-step technique under attack, Liu Xiangshould be trained to focus on starting reaction speed of2-3bar connection and sprintfinish capabilities.3. compared to the previous eight-step attack first column technology, the newtechnology at the starting seven-step attack bar weaker than previous technologies,explaining the new technology is not a hundred percent maturity. Liu Xiang, the coreshould be trained on the new technology improved on.4. Liu Xiang in the changes the new "seven-step attack first column," theachievements of world attention, combined with the110-meter hurdles Hurdling is ahigh technology content and difficult to master the sport, coaches, athletes should begiven as soon as possible to develop appropriate its development model technology.5. athletes participating in the future, it should be the case according to theopponent, the game nature and the environment, and many other factors to developappropriate coping tactics and tactical implementation of daily training spot to go.
