태권도 선수의 단기간 체중감량이 스트레스호르몬과 피로물질에 미치는 영향

민창기 ( Chang Ki Min ),김동균 ( Dong Kyun Kim ) 대한무도학회 2010 대한무도학회지 Vol.12 No.1

본 연구의 목적은 태권도 선수의 서로 다른 체중감량방법을 비교·분석하여 계체 후 스트레스와 피로물질에 어떤 영향을 미치는지 규명하는데 있으며, 효과적인 체중감량방법을 도출하여 경기력 향상에 도움을 주는데 있다. 고등학교 태권도 선수를 21명 대상으로 정기적인 운동 후 30분 동안 A Group(Running), B Group(Running+Sauna), C Group(Sauna)으로 3일간 자기체중의 6%를 체중감량을 하였다. 채혈은 계체 전 과 계체 후 30분이 지난 시점에서 전완주정맥에서 채혈하였으며 카테콜라민의 경우 HPLC 방법, 젖산의 경우 비색법 방법을 실시하였으며 체중감량방법간의 스트레스 호르몬과 젖산의 변화량을 측정한 결과 다음과 같은 결론을 얻을 수 있었다. 런닝과 사우나를 병행한 그룹에서 런닝과 사우나만 실시한 그룹보다 카테콜라민에 긍정적인 영향을 미친 것을 알 수 있었다. 하지만 피로물질인 젖산은 복합처치가 신체의 대사기능이 떨어짐으로써 심폐기능이 저하로 인한 피로도와 경기력의 저하를 가져올 가능성이 있다고 사료된다. 그러므로 단기간 체중감량 보다는 장기간 체중감량을 체계적으로 실시한다면 경기력 향상에 도움을 줄 것으로 사료된다. For the purpose of this study, an experiment was conducted with 21 high school Taekwondo athletes. They were put to a weight-loss training program after their routines separated in three different groups, namely Group A (Running), Group B (Running + Sauna), and Group C (Sauna), for 30 minutes to reduce 6% of their body weight. The blood samples will be taken 30 minutes before and after the body weight measurements from the vein at the fore arms. And HPLC method was applied for Catecholamine and colorimetry was applied for lactic acid. After measuring the amount differences between the weight-loss methods in terms of stress hormones and lactic acids, the following discoveries have been made. In the end, the group which was engaged in both the running and sauna treatment showed a positive effect on Catecholamine compared to the groups engaged in running and sauna only, respectively. However, as for the lactic acid, which is a fatigue substance, it may leave a negative impact on the athletes` performance as the metabolic function gets hindered due to the combined treatment, causing fatigue and impediment in cardio-function. Therefore, it is recommended to avoid losing weight in a short-term period. A systematic weight loss program over a long term will positively enhance the performance of the athlete, instead.

Mainly to analyse the biomechanical variables for the successful attack factors in Kumdo bouts. In this context, 34 games with 36 players, that were filmed by S-VHS video camera. The bouts included 34 games of 27 preliminary matches for National Kumdo Championship Tournament of President Cup held in November 2009 and final 7 games of the round of 8 groups. For game content analysis, attack frequency, success rate, failure rate, gain, and gain time by section were considered. Based on this condition, I analyzed the pace, speed, angle between bamboo sword and ground, angle speed of bamboo sword"s first part, and its movement, attack distance and stroke time that give impact on the outcome of the match when attacking head and wrist were analyzed. And for the evaluation of related factors in attacking movement, the regression analysis of logistics about the biomechanical variables were employed. Through this analysis of biomechanical variables and game contents, the following outcomes were drawn. Among the biomechanical variables that showed the significance in statistics were the pace, angle speed of bamboo sword, and the attack range. The pace for correct posture and movement was 48.7±25.6cm in successful attack of head and 65.2±23.3cm in failure. Among the biomechanical variables that had an effect on attacking movement, the pace and attacking distance were related in attacking head. The ratio of the pace compared to the height was 26.4±14.1% in that of wrist. In aspects of biomechanical factors, pace and attack distance showed the relations with the outcome of performances in attacking head. For effective strikes in biomechanic process, even no significant variables in statistics are to be considered for efficient technique combined with physical and co-responsiveness. Therefore it is recommended that strikes, maintaining the spiritual and physical drive in successful performances will be integrated ineffective drills.

This study aim was to investigate the effect of career self-efficacy on career decision-making in physical high school students and support fundamental material for decision-making process. For this study, 470 of male and female high school students(third grade) who selected randomly from fifteen sports high school in the provinces and the cities were participated. For data analysis, mean and standard deviation scores were calculated, descriptive analysis, factor analysis, reliability analysis, t-test, one-way ANOV A and multiple regression analysis were used. The result of this study were as follow: First, female students of sports high school showed higher career self-efficacy and the group of between 3 to 5 years’ career experiences showed higher career self-efficacy and the group with prize-winning experiences demonstrated higher levels of career self-efficacy. Also, high level of household monthly income demonstrated higher career self-efficacy. Second, the group of man-to-man type sport events scored higher career decision-making and the group of prize-winning experiences showed meaningful significance indicating higher career decision-making. In the variable of parents’ education level the students whose parents’ education level was lower than others showed the tendency to use the intuitive type of decision making. Lastly, All factor of career self-efficacy including rational type, intuitive type and dependent type showed significantly effect on career decision-making. Therefore, this study may suggest that solving problems variable is more important to improve their self making decision and leaders should recognize that the solving problem ability is meaningful and they need to draw students’ ability to make their decision.

PCV (Positive Crankcase Ventilation) system recirculates the blow-by gas inside of engine for emission regulation. As the blow-by gas transports oil droplets to air intake system that can result in oil consumption, deterioration of engine durability, engine torque drop and harmful emission, an oil separator with good efficiency is required. In this study, an experimental approach was taken in order to investigate an influence of each design factor of baffle separator to oil pullover through breathing air passage in high load conditions. Transparent cam cover was made to find out the oil pullover to breathing passage. After radical oil reversion phenomenon was observed, pressure distribution in cam cover oil separation chamber was measured in some areas to investigate an influence between pressure drop and oil reversion. As main factor was defined by visualization test and pressure measurement, some alternatives are developed to reduce a pressure drop and oil reversion. The final solution to prevent drastic oil reversion was verified through oil pullover test with catch jar.

This paper is to survey the cooperation between the school and the community with respect to the degree of share of their facilities. The hypothesis of this paper is that the share of facilities between the school and the community is helpful for the two. That is, the community, using the school facilities, can educate to upgrade its people to higher social level. The school, using the community facilities, can compensate insufficient school facilities and facilitate student learnings. This paper employed both a literature survey and a case study approach explained by the case of Seong Dong Gu and its schools. This paper argued that the share of the facilities between the school and the community is needed to facilitate student learnings and to upgrade community people to higher level. Thus, government should encourage the cooperation between the two. This paper found that the school can use other schools' facilities, camping facilities, various types of private institute, community libraries, social welfare centers, athlentic facilities, and park facilities in the community. Most of the facilities are rested during school hours and are vacant more or less after school hours, so that there are still room for share the facilities with the students. This paper found that the community can easily use school facilities for life-long education programs, house-wife classes, athlentic programs for daily life, recreation classes for community people because the school is located in the center of the community. These programs using school facilities can encourage to upgrade community persons' social levels. However, this paper found that the degree of community use is insufficient to fulfil the school facilities. Only a few percent of the school class rooms and other facilities are used by the community. Therefore this paper asserted that community education programs using school facilities should be expanded. This paper recommended, based on the findings, that governments should encourage the cooperation between the school and the community to facilitate student's learnings and to upgrade community people to higher level. Also it recommended that the school should share more community facilities and that the community should share more school facilities.
