Kinematical Analysis Of Technical Characteristics About Run-up Pour2Step To Takeoff Stage On The High Jump Of Chinese Elite Male High Jumpers

Based on this study adopts the method of documentation, expert interview method, using two CASIO brand high-speed cameras to3d shooting game, using the ariel analysis system (APAS) on athletes two final step run-up to takeoff technique of video analytic method, mathematical statistics and comparative analysis,(the technical features of our country with the world’s best players the contrast of kinematics, and athletes in China itself), aims to high-jumper tion technology of kinematics research, explore its inner connection of technology and laws.Through the comparison and analysis, conclusion is as follows:There is still a big gap between the world fine players in the overall level.Vertical velocity are athletes get larger lift height, the key to achieve good results of the competition.Good run-up, swing and stretching technology is the foundation of the athletes get bigger take-off vertical speed.Swinging leg has the advantage that swing radius short, oscillation amplitude is large, the faster the swing, the more athletes will run-up speed into the center of gravity of the level during takeoff when vertical speed.Reasonable take-off distance and smaller take-off Angle allows athletes to master the accurate jumps location, obtain good take-off technology, is advantageous to the athletes get larger take-off vertical speed.There exsits the problem that our high jump anthletes takeoff Angle slightly larger, jump distance is a bit close to the rail, swinging leg swing radius is too large, swinging leg angular velocity is relatively lower, these factors influence the players when they jump takeoff leg stretching of each joint Angle and take-off time, causes our country athletes take-off vertical speed significantly lower than the world outstanding players, ultimately affect the high jump.Zhang Guowei failed to jump takeoff point too high; Zhang Guowei’s take off leg stretching when the upper back, too much air movement control is poorer, not stretch enough.Wang Yu’s body introversion is inadequate. Jin Qichao’s swinging height and angular velocity of swing is too small.
