(1.College of Physical Education,Shandong Normal University,Jinan 250014,China;2.College of Physical Education,Liaocheng University,Liaocheng 252059,China) Abstract:The authors used two Sony high speed video cameras to shoot part of the excellent male back-crossing style high jumpers in China in the contest field synchronously and analyzed the video by applying Aijie sports video feedback system,and revealed the following findings: At the instant the lift-off began,the vertical speed of the body’s center of gravity was kind of low; the hip joint,knee joint and ankle joint of the lift-off leg were not stretched out sufficient enough,the swinging speed and height of the swinging leg were kind of low,and the horizontal run-up speed failed to be turned into vertical speed rationally;the vertical speed of lift-off was the main factor that affected the performance of male high jumpers in China. Key words:lift-off technique for high jump; three dimensional kinematics; male high jumper; China |
