Taekwondo has developed into a global sport that sports 80 million people from 208 countries around the world. Korea is the mother country of Taekwondo, and there are many international Taekwondo events in Korea. As important as the image of Taekwondo contents, it will be operation plan and management for event facilities. In particular, safety management for participants is more important than anything else. In case of Taekwondo where there are many national events, there are many foreign visitors, so safety management in facilities and running programs needs to be important. In this study, we conducted in - depth interviews with experts with a career in Taekwondo events. Based on the in - depth interviews, we analyzed the safety management problems of the international Taekwondo events and suggested improvement directions to overcome them. Based on the results of these researches, the improvement direction of Taekwondo event safety management proposed in the first category is a demand for improving safety and injury related system construction. The second category, the safety improvement of visitors, is to secure professional manpower and secure budgets. Also, what is important in the third category, facility safety area, is the proposal to introduce facility safety certification system.

The purpose of this study was to investigate the effects of six weeks of plyometric training on Sargent jumps, posture control, and lower extremity injury criterion in Taekwondo demonstrator. Twenty healthy collegiate Taekwoondo demontrators were randomly assigned to either an exercise group (Ex = 10), and a control group (Con = 10), Con maintained their normal Taekwoondo demontration training schedule. Whereas Ex group completed the plyometric program in three times a week, 60 minute for 6 weeks. Testing before and after training include the Sargent jump, back muscle strength, Y-balance and lower extremity injury criterion. There are no significant increase in back muscle strength, but significant increase in Sargent jump. In postural control, the anterior was not significant, but there was a significant increase in the left and right posterolateral, posteromedial and the total score showed that there was no risk of injuries. In conclusion, plyometric training is a training method that needs to be actively utilized for power, dynamic posture control, lower extremity injury prevention, and rehabilitation.

The aim of this paper is to design and evaluate calf braces that are equipped with Electrical Muscle Stimulation (EMS) modules. These braces are intended to alleviate calf pain in PARA Taekwondo athletes. The paper also seeks to assess the effects of different textile electrode designs. PARA Taekwondo participants are at a heightened risk of injuries and pain due to the nature of this exercise, which is designed for individuals with disabilities. Additionally, there is a significant risk of strain on the lower limb muscles in PARA Taekwondo compared to regular Taekwondo. To address this issue, calf taping methods are commonly used. In this study, we develop calf EMS protective gear and aim to examine the effects of different textile electrode designs inspired by taping methods. We evaluate the differences in the effects of three different textile electrode designs through visual analog scale (VAS) and range of motion (ROM) measurements. The results show that EMS protective gear has the potential to reduce calf pain among PARA Taekwondo athletes, with electrode designs inspired by kinesiology taping providing the most effective pain relief. This research suggests that these findings may be applicable to other sports disciplines, body areas, and everyday pain relief scenarios.
