Kinematic Analysis Of The Take-off Technique Of Zhang Yaoguang, An Excellent Male Long Jumper In My Countr

Special technical training is an important part of the long jump training practice,and it is the most direct and important factor that determines the athletes’ special competitive ability.The quality and stability of special technology are the prerequisite for the efficient performance and economic application of physical fitness.The learning and training of special technology runs through any period of the whole career of athletes.This paper uses the literature method,interview method,sports image analysis method,mathematical statistics method,logical analysis method to analyze the sports technology,and summarizes the conclusion:The last two steps before the board are relatively slow,but the step length of the last step reduces the flying time for the last step;the last two steps of the last step is better than the other players.The small ground Angle increases the impact of the ground on the jumping leg,so that the buffer range is larger and extends the buffer time;the jumping knee pedal extension range is smaller,which affects the jumping effect.Although Zhang Yaoguang’s loss of horizontal speed in the start-off process is small,the ability to effectively use the horizontal speed obtained in the start-up process to transform into the vertical speed is insufficient,which is directly related to the small extension range of the start-off pedal,which affects the final start-off effect.
