摘要：Background and Study Aim: The tools used in sports games (competition training) are one of the important factors for the athletes and leaders who perform the games and combat sports because they have a direct relation to the athletic performance of the athletes as well as the results of the games. The purpose of this study was the knowledge about the appropriateness of setting the kick impact of taekwondo Protector and Scoring Systems (PSS) by calculating and comparing the difficulty level of the kick scoring impact setting for each weight class of men and women. Material and Methods: Specifically, kick impact of men’s (n = 104) and women’s (n = 84) 10 weight classes (men: 104 games; women: 84 games) of the 2018 Jakarta Asian Games was used to confirm the difficulty level of the kick scoring impact setting for each weight class. When the difficulty of Rash model was calculated using Excel and Winsteps 3.65.0 software, differential item functioning was applied to check the difference in difficulty level by weight class. Results: First, comparing the difficulty of setting the kick scoring impact of each weight class, −68kg showed the highest difficulty and −80kg showed the lowest difficulty in men’s group. In women’s group, the difficulty was the highest at −49kg and the lowest at +67kg. Second, comparing the difficulty of setting the kick scoring impact difference of each weight class, in the male group, there was a difference between every weight classes except −80kg and +80kg. Also, the difference was found between two weight classes (−53kg and −57kg, −57kg and −67kg) in the women’s group. Conclusions: The calculated kick impact by weight class is similar and that the difference in difficulty level of setting the kick scoring impact exists has been confirmed. Therefore, this can be used as meaningful information to activate Taekwondo PSS. However, in this study, there are limitations that only the results of the appropriateness were calculated without providing the standard of setting the kick scoring impact. Also, the result can be interpreted to be limited to a specific country or region by the fact that only the data from Asian Games were used. Therefore, future studies will be able to produce more meaningful results by analyzing and using the PSS data applied at the World Championships or the Olympic Games.
