In this study, after the introduction of the differential scoring system that can score up to five points, we conducted it to find out what kind of game technology changes in Taekwondo competition and to provide basic data to improve Taekwondo players' performance. At the 32nd Tokyo Olympics, a total of 65 games were played from the round of 16 to the final of the women's four-weight taekwondo division. The results of analyzing the difference in technology frequency, score and score rate by weight class, and reduction score by rotation are as follows. First, among the women's taekwondo games, the frequency of skills in a total of four weight classes was in the order of turn kick, push kick, fist, and score, followed by turn kick, drop kick, and push kick. Second, in a total of four weight classes among women's taekwondo games, the act of falling down, going outside the limit, and catching or pushing opponents appeared in order.
