The Kinematics Of Outstanding Athlete Men’s Long Jump Take-off Technology Research In China

In the long jump, the takeoff stage as the core of part of the project, in the long jump like played in the process of transition. This study for the 12th national games in the men’s long jump final of the top eight players to perform a jump best technical action as the research object, has carried on the detailed system of research and analysis, using the literature material method, motion image analytic method, mathematical statistics analysis method and phase division method, based on the analysis of technical parameters of various aspects, so as to find out the best men’s long jump athlete in compared with the world player of the deficiencies of place, improve the overall level of the jumping movement of elite male long jump athletes, gradually narrow the gap with the world level. We go out in the final analysis, the conclusion is:l.The 12th national games men’s long jump athletes in the process of takeoff speed utilization rate is not high, this may be due to the concession work ability support legs are weak.2.The 12th national games men’s long jump athlete leaps horizontal velocity is large, some athletes in the speed of horizontal displacement and vertical displacement with reasonable speed, rate of vertical displacement is small, individual athletes to their leaps Angle is small.3.The 12th national games men’s long jump athletes Li Jinzhe and Su Xiongfeng takeoff leg stronger buffering capacity. But other athletes buffering capacity is weak.4.The 12th national games men’s long jump athletes stretching Angle average relatively low.5.The 12th national games men’s long jump athletes in the takeoff landing instantaneous body center of gravity point and the place far away, will increase the resistance of horizontal movement, cause upper not active enough, directly affect the final takeoff effect6. The 12th national games men’s long jump athletes sectored Angle is too large, it may be caused by their performance with the world elite athletes performance gap of another important reasons.6.The 12th national games men’s long jump athletes have a larger buffer time, total time is relatively long, is also the biggest proportion of three periods, explain the 12th national games men’s long jump athletes buffering capacity is relatively poor.7.The 12th national games men’s long jump athletes jump three times of the characteristics of vertical distribution of buffer time stretching time translation, in theory, such time division characteristics will have a lot of differences, especially the division of buffer time and conversion time is not reasonable.
