Abstract: For the first time in the world, Chinese athlete Zhou Shixiong completed 450° turn to handstand on parallel bars. This article applies 3D video analytic method to collect Zhou Shixiong’s kinematic data in the competition, uses immersive 3D virtual reality technology to reconstruct the obtained kinematics data, and makes kinematics analysis in the form of three dimensional animation after 360° rotation-reproduced observations. The study shows that although Zhou Shixiong completed this action in the game, it is still not perfect. The main problems include that he stretches hip earlier, and his swing scope is slightly wide in upswing stage. This leads to the result that when he supports his body with one arm, the horizontal distance between his body center of gravity and the supporting point is too wide. As a result, his body tilts and this affects his subsequent handstand action. Besides, his two legs are not fully closed in the swiveling phase.
