Wang Jianan's Long Jump Technical Analysis

Long jump is the human body through a certain distance to get the maximum horizontal speed,and the rapid use of take-off vertical speed to make the human body into the bunker of a sports[1].Based on the 2015 Beijing World Championships Wang Jianan jump Chinese jumpers in the run-up speed after the ten step,the take-off take-off angle and flight posture and landing technology research and analysis,and with the world elite men long jump technical comparison,using the related literature search,collect relevant data and through the game,biomechanics study on the body shape,physical fitness activities of the body,while Wang Jianan’s long jump technique for biomechanical analysis,take the video screenshots to analyze the flight posture effect,the related data finally obtained by mathematical statistics method,logical analysis methods are summarized,and find Wang Jianan with the world’s advanced athletes gap from it,and put forward the improvement of its shortcomings,for the future to provide good training Good intellectual support,and provide some reference for China’s excellent athletes training and technical improvement,four key aspects of the study of Wang Jianan’s long jump technology in-depth analysis of the results of the following discussion:1.The object of study,accelerate the speed level and world elite level athletes in the run-up in the run-up to a certain gap,and the first few steps in cadence slow pace is longer,upper body leaning forward too,arm force coordination,rhythm is not strong,especially in the countdown to the first step when body weight drops too fast no,the trunk straight,his head is too slow,hands are not coordinated.2.The research object in the take-off buffer time,conversion time,stretching time is too long,resulting in the take-off angle is small,the conversion efficiency is low,the pedal is not enough,seriously affect the Wang Jianan long jump results.3.The research object in the landing buffer when the take-off leg hip angle is large,the work distance is not enough,the process of swinging leg swing to drive through the ipsilateral hip forward movement in full,then from the plate when the difference is big,swing hip swing leg is notincreased.The object of study.Flight take-off,the swing leg falling back posture was small,uncoordinated,the take-off leg stretched forward enough.4.Flight study of the take-off,the swing leg falling back posture was small,uncoordinated,the take-off leg stretched forward enough.5.The object of the study is in the air when the ground is serious to the left,the body posture is not enough,the center of gravity is too backward,hand movements are not coordinated.
