  • Purpose: The purpose of this study is to provide the basic data for technical performance by analyzing and presenting the differences in major kinematic factors in the jumping phase, flight phase, and finally striking phase for national team and non-national team male demonstration members. Method: As for the subjects of this study, 6 members of the national team and 6 members of the non-national team who had more than 3 years of demonstration experience were selected and tested. Before entering the experiment, a consent was secured from each subject, the experimental procedure was explained, and kinematic data were collected by using 14 high-speed digital cameras. For the statistical processing of this study, the mean and standard deviation (M±SD) were calculated by using Excel 2018, and the statistical program (SPSS 22.0, SPSS Inc., Chicago, IL, USA) was used to verify the difference in kinematic variables of dwigongjungdorachagi motion. The Shapiro-Wilk verification was conducted to confirm the normality of the collected data, and according to the results, an independent sample test (independent t-test), test (Mann-Whitney U-test), and the correlation analysis were performed. Results: There was a statistically significant difference in P3 (p<.05) of the required time phase. There was a statistically significant difference in E4 (p<.05) of the (Z) movement displacements. There was a statistically significant difference in the right E4 (p<.05) of the right ankle joint angle. The correlation coefficient between the body center’s displacement and flight time showed a high correlation and showed a statistically significant difference (r=.953, P=.001). The correlation coefficient between the angular velocity and the body center’s displacement showed a high correlation and showed a statistically significant difference (r=.809, p=.001). The correlation coefficient between the angular velocity and flight time showed a high correlation and a statistically significant difference (r=.809, p=.001). Conclusion: As a result of the experiment, the swing speed of the arm and the angle of the knee joint before jumping during dwigongjungdorachagi provided a great force to project the human body into the air and also had the effect of increasing vertical ascent. Hence, it is apparent that the coordination of movements is a very important factor.

Fourth, the sports attitude (physical and emotional) factors of taekwondo athletes had a positive effect on the perceived competitiveness factors. Conclusion: Based on the restrictions of this research, I would like to present the direction to the next research as follows. First, since this study was conducted on athletes in the details of taekwondo, it is somewhat difficult to generalize to all taekwondo people. Therefore, in subsequent studies, it will be judged to be more diverse if the results are derived not only from the competition but also from the birds, demonstrations, and the leadership of the defeat leader. Secondly, while this study is registered as an athlete of the Korea Taekwondo Association, it is somewhat difficult to represent all athletes because the population is composed of high school athletes. Therefore, in the subsequent research, it is judged that various results will be obtained if the athletes in the field of physical education who are not registered as athletes and the athletes who retired and belong to the university or elementary school are included in the research.
