Kinematics analysis on the shot putting technique of back gliding of China's female shot putters

In this paper, Shanghai female shot-putter Shou Qianwen was selected as the research object, and also the methods in the biological mechanics were used to analyze and research her movements of shot putting techniques. As a result, at the sliding step stage, the maximum swinging velocity of her left leg emerged too early, the joint between the take-off and swinging techniques was not very ideal, and the angle between the calf and the ground when the right leg departed from the ground was too large. However, at the transition step stage, the body weight velocity fluctuated too largely, and its single support time was too long. At the final exertion stage, the posture of her body before the apparatus was highly sufficient, but the exertion movement of the body was too hasty, and the hip movements were insufficient, which was reflected on that the exertion point was not prominent, the acceleration effect was insignificant, and the shooting speed was not very fast, and also the shooting angle was too low.
