Take our country’s three excellent woman shot throwers as research objects; apply 3D photography, video analysis and mathematic statistics method to make analysis of kinematics features from right leg land phase to left leg land phase in the aspects of speed, time, and displacement and angle such parameters. The research results show that 3 throwers body gravity center’s speed and shots speed has been improved to different extent, but upper body’s early lift caused small differences between shot speed and body gravity center speed as well as insufficient equipment exceeding postures; Except for Li Ling, other two members take too long time in transition phase; Except for Li Mei-Ju the other two members take too long knees bending buffer time when left leg landing that effect on the effective use of shots technical complete actions speed rhythm and gliding impulse.
