Abstract

The article uses the literature data method to review and collate relevant literature materials at home and abroad, and through on-the-spot shooting of the discus throwing skills of the women discus athletes Feng Bin, Su Xinyue and Chen Yang in the April 2018 national track and field throwing series. This paper uses three-dimensional video analysis software to perform a point-analysis on the last forceful technical movement of their best performance in the game, and obtains a comparative analysis of relevant kinematic parameters. The study concludes that: first, the initial speed of the three discus throwers is slow, and there is a certain gap between them and the world's top athletes; Feng Bin and Su Xinyue's shot angle is more reasonable than Chen Yang; second, in the final exertion phase, Feng Bin and Su Xinyue spent less time than Chen Yang and completed the action process faster. At the time of the left foot landing, Feng Bin and Su Xinyue had better shoulder and hip angle parameters than Chen Yang. Chen Yang did not form a good surpass. The posture of the device, discus throwing moment, Su Xinyue's pull lead angle is higher than Feng Bin and Chen Yang, her technology is more reasonable. In the final stage of exertion, the two-legged station is far from Feng Binyao than Su Xinyue and Chen Yang, leaving enough room for the body to move.
