Comparative Study Of Chinese Elit Women400m Hurdlers Full Speed Rhythm

The particularity of400m hurdles determines the complexity ofchanging speed. The particularity results in that it has a higher demadof400m Hurdles athlete’s physique. With the reduction of talents, theachievements of the women’s400m Hurdles has shows a decline in the worldrankings. This text takes literature data, image processing method andmathematical statistics, comparative analysis method, logical analysisand other methods to compare the two different grades of Huang Xiaoxiaoand compare the competitions in the Guangzhou Asian Games between WangXing and world’s top athletes. With the comparative analysis we can knowthat our athletes has a poor power to control. Our athletes has seen adramatic acceleration in the acceleration stage. Overall faster in thefirst half, it result that the time gap is too large in column5beforeand after. The rhythm change of bar speed is not enough smooth,unsteadiness, Speed curve shows a wave change; the physical allocationis not enough. After the drive, the speed drops too much. Poor abilityto maintain a high running speed and the position to increase the numberof steps between hurdles is too early, so we should increase the abilityof15-step over the hurdle. In the case of that, the number of steps hasa substantial increase. The cadence of bar has also decreased. It showsthat we lack viability of stride frequency.
