N2 - Background and Study Aim: Material and Methods: Results: Conclusions: In sports matches, athletes mostly perform repetitive motions in predetermined spaces. Repetitive motions become different according to the features of teams or athletes, which give direct effect to match results. The aim of this study is knowledge about preferred by world-class taekwondo athletes scoring patterns. In this study, association rule was applied to identify data scoring patterns depending on match conditions of world-class taekwondo athletes. We recorded variables of match contents (match condition, position on court, match round, and type of attack) for instances of trunk scoring by subjects from 293 matches from the women’s division of the 2017 Muju International Taekwondo Competition. It was found that the scoring frequency was 865 in the 293 matches and we performed frequency analysis and association rules analysis of match content variables based on the recorded data. Excel and a rules Viz in R package were used to statistical analyse data. First, the scoring patterns of taekwondo athletes in a tied state had the highest association with scoring in round 1, centre court position and defensive attack. Second, the scoring patterns in a winning state had a higher association with scoring in round 3, corner court position, and offensive attack. Third, the scoring patterns in a tied state had a higher association with scoring in round 1, centre court position and defensive attack. Fourth, the scoring patterns in a losing state had a higher association with scoring in round 3, dominant court position and offensive attack. Considering that a large quantity of information other than variables selected in this study may be produced, this study cannot help having some limits. Further information can be identified when calculating the results by classifying weight class or athlete features. In future studies, that further information can be provided when processing studies considering trunk and face scoring and point deductions being highly associated with performance as well as the above mentioned limits.
