Comparison of Physical Strength Characteristics According to Performance Level of University TAEKWONDO DEMONSTRATION Majors

Jusik ParkPurpose: The purpose of this study is to provide useful information on physical fitness training to improve the performance of Taekwondo demonstration majors by identifying the characteristics of physical fitness factors ac-cording to the performance level of university Taekwondo demonstration members. Method: The subjects of this study are Taekwondo demonstration members enrolled in K University located in D city. The differences in body structure, physical fitness factors, isokinetic muscle function of the knee joint, and anaerobic exercise capacity were compared and analyzed for 3 male students in the national demonstration group and 3 male students in the general demonstration group. Results: As a result of measurement of body structure, physical fitness factors, isokinetic muscle function, and anaerobic exercise capacity of the national demonstration team and general students, there was no statistically significant difference between groups. However, through the results of this study, it was confirmed that the ratio of flexor and extensor muscles needs to be improved to an ideal ratio of 55% to 65% as suggested in previous studies to prevent damage to the lower extremities of general students. In addition, the standing long jump and sargent jump, side step, eyes closed and one leg standing, and knee joint isokinetic muscle power showed a high-er tendency in the national demonstration group compared to the general students. There was no statistically significant difference between groups in the measurement results of anaerobic exercise capacity. Conclusion: Based on the results of this study, it is thought that it will be difficult to present the characteristics of the physical fitness factors according to the performance level of Taekwondo demonstration majors. However, considering the results of many previous studies and this study, it is thought that efforts to improve agility, power, and balance ability are needed to improve the performance of Taekwondo demonstration majors. It is judged that improvement of the flexion muscle/extension muscle ratio of the lower extremities is necessary to prevent addi-tional injuries.;Jihye Jeong;Jonggyu Son;Gangjun Kwon
