The Three-Dimensional Kinematics Parameter Analyzes On Backward-slides-step-shot-put Technique Of Same Outstanding Man Shot-putters In China

Analyzing and diagnosing the man shot put technique to raises our country man shot movement overall level has the vital significance. Designates the first 6 athletes who enter in 2004"Fei Pu Lai Cup"national track and field grand prize series match the male shot competes as the research object. Uses two JVC9800 high speed camera by the 50fps speed synchronization photography, carries on the picture using the German SIMI-motion video recording analysis system analyzes. The results as followers: (1) Our country athlete is sliding the step of stage suspends the pedal technology is irrational, after moving legs placed high, the ups and downs of the larger focus, left knee swing speed maximum speed and physical focus a very significant correlation value, and shot a remarkable value of the relationship between speed. (2) the transitional stage technology movement has the stop, undesirable effects beyond appliances, left leg swing not timely and speedy landing, the right leg after landing don′t timely and speedy button up and push, left support technique is unsatisfactory, the transition time with the world of outstanding athletes have significant differences. (3) Finally forceful stage, the release speed and angle of delivery have very highly significant with foreign athletes, the angle of delivery have significant differences.
