고등학교 태권도 겨루기 선수의 체격 및 체력에 따른 경기력 결정요인 분석

This study aims to analyze the performance determinants of high school taekwondo kyorugi athletes. For this purpose, the physique and physical strength of 46 excellent athletes selected on the national team and 79 high school taekwondo athletes nationwide, who were non-excellent athletes selected as the comparison group, were measured. We check whether there is a difference in physique and physical strength between excellent and non-excellent athletes by performing an independent sample t-test on this data. Additionally, we derive a decision tree model and a logistic regression analysis model for predicting performance after applying the T-score to remove factors caused by gender and weight class. The study results are as follows. First, the height and PACER of excellent and non-excellent athletes differ, and other factors may differ according to gender and weight class. Next, the most critical determinant of performance was identified as PACER. Finally, the logistic regression model showed better predictive power than the decision tree model. The results of this study are expected in the selection and training plan of high school taekwondo Kyorugi athletes.
