The purpose of this study was to investigate the effect of carbohydrate ingestion after weight reduction on catecholamines and isokinetic strength. Sixteen Taekwondo athletes (21±1.21 yrs) were matched and randomly placed into carbohydrate ingestion and placebo ingestion. Each groups reduced body weight by 5% during 2week. Altered Åstrand protocol used to measure maximal exercise capacity with arm ergometer. Muscle strength, power, and endurance were determined using Isokinetic dynamometer (Cybex-Ⅱ system). Blood sample was obtained at rest, during 10minute and immediately after completion of the test, and recovery(30min, 60min). Catecholamines concentration (epinephrine, norepinephrine) increase after weight reduction and the rate of increase was more higher in norepinephrine in contrast to epinephrine. Carbohydrate ingestion decreased this variable after weight reduction and the rate of decrease was more higher rather than placebo group. In isokinetic strength test, strength and power did not show any change after weight reduction, but endurance decrease significantly. In endurance test carbohydrate ingestion recovered this decrease to base line level and the rate of recovery more higher than placebo group. In conclusion weight reduction in weight class athletes changed metabolic substrate and hormone and decreased exercise performance. Carbohydrate ingestion altered this change and recovered exercise performance partially. Further study needed to elucidate the exact mechanism with weight reduction and carbohydrate ingestion related to muscle glycogan and DNA syntheses.

This study aims to analyze the method of managing athletes and referees who participate in the Incheon Asian Games and collect tactics and strategies for athletes to get ready for Brazil Rio Olympics, 2016. Through the results, the following issues and points of improvement could be drawn. First, in the past, South Korea has maintained the first or second ranks promoting its own status as the country from which Taekwondo has originated, but now, it is very difficult to get good results in international competitions. Second, in fact, Korean athletes have poorer international perspectives and experiences since they are frequently substituted through a repeated selection contest each year. Thus, it is necessary to introduce a new system for the selection contest that can continuously maintain national team players. Third, according to the current game rules, facial techniques consist of the concept of touch, so leaders often ask for a review (video replay). It is desirable that converting the touch on the face to the concept of hit. Fourth, associations and participants should focus on increasing its status as the country from which Taekwondo has originated through more investments, and the leaders of each team should fast recognize and learn the game rules of international competitions which change each time, and they should instruct athletes to effectively cope with them at the site of the competition through quality training. Fifth, South Korea should obtain information about many excellent athletes of other countries and share and analyze it with its athletes in order to develop the best training program. Moreover, Korean athletes should increase their individual skills so that through their many game experiences, they can get good results on the international stage as well.

The purpose of this study is to analyze the game of all four classes of men and women participating in the Rio Olympic Games in 2016 to analyze the technology according to the Olympic Taekwondo competition. That was the purpose. The results are as follows: First, the World Taekwondo Federation has introduced a ranking system to increase the popularity of the Olympic Games and the popularity and reputation of the best players since the Liu Olympic Games, but it has led to some problems. Second, G1 and G2 open competitions were approved, and the way in which the athletes earned score points for their participation resulted in the development of rich and poor people. Third, in the case of the Grand Prix, it is difficult for top athletes to participate because of their participation in the 32nd rank of the world rankings. In the Grand Prix, Grand Prix winner of the Grand Prix Final (G4) It is unreasonable in terms of the opportunity to participate in the Olympic Games because new players and weak players are not able to compete because they acquire the score. Fourth, in order to survive in the Olympic Games and the Olympic Games in Tokyo, research and development of techniques using sole sensors are required. Fifth, KP & P is currently scoring in the field because it uses two electronic huts such as Dae Do and Dae Do. For that reason, researches on improvement of electronic hut and more advanced technology have not been made. There is a need for improved and high quality electronic equipment through more investment. Sixth, there is currently no skill for two points because there are one point of fist, three points of face, and four points of face technique by rotation. I think that the scoring technique for two points should be added as soon as possible.

The purpose of the study is to check whether the relative age effect appears in male combat sports athletes. For the study, athletes in wrestling, judo, boxing, and ssireum events, registered in 2017, 2018 and 2019, were selected as research subjects. This study used Chi-square and Spearman rank-order correlation to identify whether the relative age effect appeared in male combat sports athletes. The results of the study are as follows: First, the study identified the difference between the distribution of the birth month of male combat athletes and the distribution of the birth month of the public. As a result, there was a difference between the distribution of birth months in wrestling (2017), judo (2019), and ssireum (2017, 2018, 2019). Second, the correlation between the birth month ranking and relative age birth month ranking of male combat athletes was confirmed. The results showed statistically significant static correlations in all sports except boxing (2019). Third, considering the above results, the relative age effects were shown in wrestling (2017), judo (2019), and ssireum (2017, 2018, 2019). Through the results of this study, the phenomenon of the relative age effect in male combat sports athletes in Korea was identified. The results of the study have identified the relative age effect of domestic male combat sports athletes. In particular, it can be meaningful in that it has confirmed the relative age effect for the domestic combat sports athletes.

The purpose of this study was to analyze the structural relationship of university Taekwondo player's psychological factor in Tenacity, mistake recognition and grit. For that purpose, we conducted a questionnaire to 291 university student athletes registered with the Taekwondo Association. Based on the collected data, frequency analysis, normality verification, confirmatory factor analysis, Cronbach's α, and structural equation model were applied to calculate the results. Excel 2013, SPSS 21.0 and AMOS 23.0 were used. All statistical significance levels were set to 05. The conclusion from this is as follows. First, the error recognition factor was found to have a positive effect on the effort factor among the grit sub-factors. Second, it was found that the mistake recognition factor had a positive effect on the competitive strength factor. Third, among grit sub-factors, the effort factor was found to have a positive effect on the winning streak. In conclusion, it was confirmed that a positive attitude toward the mistake recognition contributes to increasing effort and Tenacity, and it is confirmed that continuous effort has a positive effect on achieving individual goals.
