A Comparative Analysis Of Zhang Guowei's And Foreign Excellent Men's High Jumpers' Back-to-Low Jump Techniques

Based on the reference method,video analytic method,mathematical statistics research methods such as men's high jump athletes Zhang Guo-wei to our country and foreign elite male high jump athletes in the high jump sports to collect the data.From the human body in motion should follow the objective law of constructing phase of fosbury flop different body should be a reasonable framework,and on this basis,the collected Zhang Guo-wei in the phase of the parameters such as run,jump,pole with the foreign excellent athletes horizontal comparison,find out its in fosbury style high jump technology of deficiencies.The following conclusions:1.Chinese men's high jump athletes Zhang in the run-up speed has reached the world's best level,but Is speed loss is bigger,in the process of the run-up in the last step to takeoff batter Angle is small,body to End of the approximate linear movement trajectory run-up against physical nature back to bar after suspension.2.Zhang Guo-wei's arm and smaller swinging speed of swinging legin the process of takeoff,ankle explosive force is weak,jump off the ground when the swinging leg swinging towards opposite side shoulder,deliberately failed to maximize technical capabilities.3.after complete the takeoff action of empty stage,deng swinging leg not active,period after stem back bow range is small,influence the efficiency of a rod.
