The present study intends to find a way to distinguish an anomalous kick that appeared as a side effect of the introduction of the electronic Protector and Scoring System (PSS) in taekwondo through Inertial Measurement Unit (IMU) sensors. The 10 normal kicks and 1 anomalous kick were selected for the study. Four IMU sensors were attached to the trunk, pelvis, and both feet of each of 10 taekwondo athletes to obtain the total acceleration and total angular velocity of the right foot based on the trunk and the pelvis. Seven athletes were randomly selected to calculate the reference data of 11 types of kicks and the data were compared with the data of 11 kicks of the remaining three athletes through correlation analysis. The accuracy of distinguishing the anomalous kick through each variable was 83.3%, and the probability of misunderstanding a normal kick as an anomalous kick was 6.7%. When the results of the correlation analysis of the four variables were synthesized and analyzed, the accuracy of distinguishing anomalous kicks improved to 100%, and the ratio of cases of misunderstanding normal kicks as anomalous kicks decreased to 0%. The results of the present study provide a simple but reliable method to distinguish anomalous kicks in taekwondo competitions. If the limitations of the findings of the study are settled and introduced into the taekwondo EPSS, the problem of anomalous kicks in current taekwondo competitions can be solved.
