The purpose of this study was to investigate the effects of a winter training camp on physical fitness, physical self-efficacy and nutrients intake in juvenile Taekwondo players. Sixty three subjects of male middle school student Taekwondo players participated in this study. Before and after attending Taekwondo winter training camp, Taekwondo related fitness and physical self efficacy and nutrients intake of subjects were measured and compared. The results of this study were as follows: 1) There were significantly improvements (p<0.001) in 1200m run, sit up, push up. 2) There was no significantly change in physical self efficacy. 3) There were significantly increase intakes (p<0.001) in total calorie, protein, fat, fiber, Ca, P, K, vitamin A, vitamin B2, vitamin B6, niacin, vitamin C and vitamin E. However, index of nutritional quality in fiber, Ca, K, vitamin A had not good assessment. These results suggested that a winter training seems necessary to keep psychological management and scientific dietary management as well as physical training in juvenile Taekwondo players.

[Purpose] We conducted a meta-analysis to evaluate the effects of Taekwondo training on the physical fitness factors in Korean elementary students comprehensively and quantitatively. [Methods] We classified research studies published until November 2018 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and selected a total of 17 research items; a meta-analysis of these items was then conducted. We used the Comprehensive Meta-Analysis 3.0 and Review Manager 5.3 to analyze the mean effect size, study quality, and publication bias. [Results] Taekwondo training improved the cardiopulmonary endurance, muscle endurance, and power of the elementary students, but was not practical or less useful on other physical fitness factors. The meta-regression analysis of the cardiopulmonary endurance and power items showed that the effect size was large when the sample size was small. Therefore, it is necessary to consider the sample size in interpreting the effect size for these two items. Further, during correction of the publication bias for the power items, the improvement effect by Taekwondo training was eliminated. [Conclusion] Taekwondo training is helpful for improving the cardiopulmonary endurance and muscle endurance of Korean elementary students but is not useful for other physical fitness factors.

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.

Objective : In order for Taekwondo athletes to perform destructive kicking performance, they are expected to have Taekwondo-specific muscle properties such as high muscle strength and power. The purpose of this study was to investigate the joint angle-dependent force-producing property of Taekwondo athletes' knee extensor muscles, which is one of the primary muscle groups involved in kicking performance. Method : Ten Taekwondo male athletes (age: $19.9{\pm}0.7yrs$, height: $180.6{\pm}6.2cm$, body mass: $75.9{\pm}8.9kg$, career: $9.2{\pm}2.9yrs$.) and 10 healthy male non-athletes (age: $26.3{\pm}2.6yrs$, height: $174.2{\pm}4.8cm$, body mass: $72.8{\pm}7.7kg$) participated in this study. Subjects performed maximum isometric knee extension at knee joint angles of $40^{\circ}$, $60^{\circ}$, $80^{\circ}$, and $100^{\circ}$ (the full knee extension was set to $0^{\circ}$) with the hip joint angles of $0^{\circ}$ and $80^{\circ}$ (the full extension was set to $0^{\circ}$). During the contractions, knee extension torque using an isokinetic dynamometer simultaneously with muscle activities of the rectus femoris (RF), and the vastus lateralis (VL) and vastus medialis (VM) using surface electromyography were recorded. Based on the torque values at systematically different knee-hip joint angles, the joint torque-angle relationships were established and then the optimal joint angle for the knee extensor was estimated. Results : The results of this study showed that the isometric knee extension torque values were greater for the Taekwondo athletes compared with the non-athlete group at all hip-knee joint angle combinations (p<.05). When the hip joint was set at $80^{\circ}$, the peak isometric torque was greater for the Taekwondo athletes compared with the non-athlete group ($313.61{\pm}36.79Nm$ and $221.43{\pm}35.92Nm$, respectively; p<.05) but the estimated optimum knee joint angles were similar ($62.33{\pm}5.71^{\circ}$ and $62.30{\pm}4.67^{\circ}$ for the Taekwondo athletes and non-athlete group, respectively). When the hip joint was set at $0^{\circ}$, the peak isometric torque was greater for the Taekwondo athletes compared with the non-athlete group ($296.29{\pm}45.13Nm$ and $199.58{\pm}25.23Nm$, respectively; p<.05) and the estimated optimum knee joint angle was larger for the Taekwondo athletes compared with the non-athlete group ($78.47{\pm}5.14^{\circ}$ and $67.54{\pm}5.77^{\circ}$, respectively; p<.05). Conclusion : The results of this study suggests that, compared with non-athletes, Taekwondo athletes have stronger knee extensor strength at all hip-knee joint angle combinations as well as longer optimum muscle length, which might be optimized for the event-specific required performance through prolonged training period.

This study is considered about the Taekwondo(跆拳道) uniform classified by period and analyzed the current Taekwondo uniform. And founded on this contents, new designs of uniform, that a functional side are considered and can symb이ize the identity of Taekwondo, are presented through this study. Ancient times to the present time, the Taekwondo uniform classified into three types according to 'Period of putting on our nation's costume'(three kingdoms${\sim}$Joseon(朝鮮) times), 'Period of confusion on uniform'(Japan's colonial rule of Korea${\sim}$-the early 1970s), 'Period of the settlement on official uniform'(the late 1970s-the present time). And besides, the shape of our nation's costume in ancient times is succeeded until Joseon times and this basic style becomes the outset on the current Taekwondo uniform. The designed uniforms are connoted the notion of the aesthetic appreciation in Korean traditional costume, that is, a symbolic, dignified, moderate appreciation with the consideration of a functional side for Taekwondo. And the contents on the presented designs are classified into 'shape, pattern, color'. First, these designs that are adapted the shape of Baji(바지) Jeogori(저고리)-belt, which have symbolized our nation's costume, and the shape of Bacja(배자) had used in Joseon times, are connoted a 'traditional appreciation with functional side'. Second, these designs, which are adapted the patterns of the active image(a bugbear, flying horse, tiger for embroidered patches, Taegeuk(太極)) in a modern style, express a 'symbolic, dignified appreciation'. Third, these designs are well-matched a black and white color with multicolored stripes(saekddong, 색동), and its ones are connoted a 'moderate and symbolic appreciation'.

The Taekwondo uniform has remained consistent since it was officially designed in a V-neck form in 1976. Taekwondo is a martial art that emphasizes social etiquette; therefore, it is necessary to dress in a uniform that reflects Korean traditions and ancient oriental philosophy. However, the current official uniform has limitations in endowing traditionality and many usability problems. Thus, recognizing the problems raised with the uniform, the Kukkiwon (World Taekwondo Headquarters) developed a new style official uniform in 2011. This study is to endow traditional meaning to a new style uniform and proposes some design modifications that can convey a more traditional adequacy. The development of the new official uniform began with a specific plan for change from the existing uniform, this study as subsequent work is significant in that its endowment of symbolism and modification proposal is for the actual execution and global dissemination of traditional Taekwondo culture. The results of this study are as follows. First, we can endow Korea's traditional historicity and symbolism to the new uniform in form and colors. All contents of the design (in which the front side is open, the top is adjusted rightward, the rear length is shorter than the front length, comfort provided by side vents, dual collars for children's uniforms, and a belt) are adapted from the Korean traditional costume. Consequently, historicity can be endowed to the uniform. It is also confirmed that the traditional oriental philosophy including heaven and earth (天地), Yin-Yang (陰陽), and Five Elements (五行) can be endowed in the use of colors. Second, in order to project deeper historicity and symbolism to the form of the new uniform, this study proposes design modifications based on the selection as an item of Simui (深衣), a type of traditional clothing that contains a high symbolism similar to the Taekwondo uniform. It proposes giving shape to the practice of manners, the righteous life, and the straightforward mind by modifying the design of the uniform in the fish belly part of the sleeves, collars, back stitches, and side seams.

The purpose of this research is to explore the role of Taekwondo in foreign migrant workers' adaptation process in Korean society, based on segmented assimilation concept by Portes & Zhou(1993) as a theoretical framework. In order to achieve this, an in-depth interview of 13 foreign migrant workers in Gyeonggi-region was carried out by using purpose sampling and theoretical sampling together, and the interview was analyzed using grounded theory method. The analysis result demonstrated that foreign migrant workers understand Korean culture, learn Korean, and interact with Koreans through Taekwondo, which facilitates their acculturation into the mainstream society. Also, they were assimilated into their own subculture of being fascinated by the charms of Taekwondo and trying to become Taekwondo instructors by returning to their home country. Lastly, they built a social network and overcame tough labor and the difficulties of living in a foreign country through Taekwondo. This research is significant as it examined the role of Taekwondo that preserves Korean culture and checked its value, in terms of the adaptation of foreign migrant workers who take a part in the current rearrangement of Korean society into a multicultural society.
