신중달(Shin Jung-Dal) 동아대학교 스포츠과학연구소 2007 스포츠科學硏究論文集 Vol.25 No.-

  본 연구는 실험동물은 분만 후 6주령 된 Sprague-Dawley 종의 Rats 48마리를 대상으로 비교집단(비당뇨유발 비트레이닝 그룹 8마리, 당뇨유발 비트레이닝 그룹 8마리), 실험집단( 10분 트레이닝, 30분 트레이닝, 60분 트레이닝, 90분 트레이닝 그룹 각 8마리)으로 구분하여 4주 동안 사육 실험을 실시한 결과 심장조직(각 실험조직 4g)의 Total DNA 양은 비교집단 당뇨 비 유발 비 트레이닝 그룹은 8.08㎎으로 나타났으며 당뇨 유발 비 트레이닝 그룹은 7.90㎎으로 나타났다.<BR>  실험집단의 당뇨 유발 10분 트레이닝 그룹에서는 8.20㎎으로 나타났으며 당뇨 유발 30분 트레이닝 그룹에서는 8.28㎎으로 나타났다. 또한 당뇨 유발 60분 트레이닝 그룹에서는 8.34㎎으로 나타났으며 90분 트레이닝 그룹에서는 7.12㎎으로 나타났다.<BR>  본 연구 결과에서 제시된 바와 같이 무리한 운동(90분 트레이닝)이 아닌 적당량의 운동은 세포내 DNA함량을 증가시킨다고 보고된 바와 같이 DNA함량의 증가는 곧 단백질 합성의 증가 가능성이 커진다는 것을 의미한다고 볼 수 있다. 즉, 단백질은 인체의 중요 구성요소로서 생리적인 측면뿐만 아니라 심리적인 측면에서의 안정감도 초래한다고 볼 수 있으며, 적당량의 운동은 당뇨환자에게서 쉽게 볼 수 있는 생리적, 심리적 불안감을 해소시킬 수 있으며, 더 나아가 당뇨로 인해 발생하는 많은 합병증 예방에도 도움이 된다고 본 연구자는 사료된다.   For this research I selected by species of the Sprague-Dawley Rats. Each group divided into two groups. One is a comparison group (non-diabetic-induced and non-training group, diabetic-induced and non-training group), the order is the experimental group (diabetic-induced group, 10 min, 30 min, 60 min, 90 min swimming training group), After swimming training, I analyzed total DNA Volume of the cardiac muscles. The non-diabetic-induced(non-training group) and diabetic-induced(non-training group) of comparison group. The method of Diabetic-induced made used of the streptozotocine. The volume of used streptozotocine is 4㎎/kg. Each other to the mean value of measurement is 8.08㎎ and 7.90㎎. Also The mean value of measurement in Experiment group is 8.20㎎ in diabetic-induced 10min group and 8.28㎎ in diabetic-induced 30min group Also 8.34㎎ in diabetic-induced 60 min group and 7.12㎎ in diabetic-induced 90min group. Like the above result, DNA Volume brought a result to increase of diabetic-induced 10min, 30min, 60min groups. but diabetic-induced 90min groups brought a result to decrease . That is, suitable sports are better for a protein increase than many hours sports in diabetes.

신중달 ( Joong Dal Shin ) 대한무도학회 2010 대한무도학회지 Vol.12 No.2

본 연구의 목적은 노인여성을 대상으로 12주간의 태권도 품새 수련(1회 60분, 주 3회)을 통하여 혈청 콜레스테롤, hs-CRP와 NT-pro BNP에 미치는 영향에 대해서 알아보았다. 12주간의 태권도 품새수련을 통하여 체지방률, 체지방량과 이완기 혈압이 유의하게 감소하였고 제지방량은 유의하게 증가한 것으로 나타났다. 그리고 중성지방 LDL 콜레스테롤과 APO B는 유의하게 감소하였고 HDL 콜레스테롤과 APO A1은 유의하게 증가한 것으로 나타났다. 특히 인슐린 저항성, hs-CRP와 NT-pro BNP가 유의하게 감소한 것으로 나타났다. 그러므로 노인여성들에게 있어 태권도 품새 수련은 혈청 콜레스테롤, 인슐린 저항성과 NT-pro BNP에 긍정적인 영향을 미치는 것으로 사료되며 이러한 결과들은 노인여성들의 심혈관질환의 발생을 예방하고 개선시키는데 도움이 될 수 있을 것이라 생각된다. The purpose of this study was to examine the effects of performing the taekwondo poomsae training(TPT) for 12 weeks(60 min/day, 3 times/week) on serum cholesterol, hs-CRP and NT-proBNP of older women, which have been regarded as risk factors of cardiovcular disease. As a result, %fat, fat mass and diastolic blood pressure decreased significantly while fat free mass increased significantly in TPT. TG, LDL cholesterol and APO B decreased significantly while HDL cholesterol and APO A1 increased significantly in TPT. Especially, HOMA IR, hs-CRP and NT-proBNP significantly decreased in TPT. Therefore, it turned out that teakwondo poomsae training has positive influences on serum cholesterol, insulin resistance and NT-proBNP for older women, and these results will contribute to preventing and improving the condition of cardiovascular diseases.

The purpose of this study is to investigate the effects of difference exercise type on taekwondo poomsae training and walking exercise on body composition, serum cholesterol and dementia risk factors in elderly obese women for 12 weeks. As the results that taekwondo poomsae training group increased significantly peakVO2max, LBM, HDH cholesterol, DHEAs and decreased total cholesterol, β-amyloid after 12 weeks. Also, walking exercise group decreased significantly blood pressure, β-amyloid after 12 weeks. Therefore, I consider that regular taekwondo poomsae training influences positively better than walking on improvement of body composition, serum cholesterol and dementia risk factors for the elderly obese women and eventually to help not only improve obesity but also prevent the dementia.

This research started to look for what are needed and need to be complemented in survival swimming education by directly taking part in the educational fields, rather than trying to point out what are the problems in the survival swimming education. The research methods are the observation of the education, interviews with learners, and interviews with teachers, all of which were carried out in comprehensive, simultaneous ways. The results of researches are summarized by three key components: First, it is the current status of the education. The learners are generally pro-active in their attitudes but their education opportunities are largely limited to one or two times without any permanent participation into durable programs. Besides, there is no education about how to cure the aqua-phobia. Second, it"s the educational contents. The contents are different from agency to agency without any standard curriculum. There is no appropriate education of theory. Third, it"s the necessity of standardization of field manuals. There is no clear division between emergency manuals and education manuals about emergency situations. I hope this research will contribute to making the related education better off.

This study is based on the perception that the lecture-assessment systems work well in their fairness and necessity when they are customized into specific majors. I divided the problems in lecture-assessment systems into the three categories. First, what are the problems lying in the learners" side? Second, what"re the problems in the side of teachers? Third, what could be done to rectify them? The research method is FGI(focus group interview) which involves research participants and teachers. The findings show that, firstly, learners have such problems as indifference to the system as they are busy athletes or hired workers, and emotionally biased responses to lectures. As for the teachers, they have such problems as misunderstanding that they are evaluated as humans, not the lectures being evaluated, teachers" flattering to the learners to ask better evaluations, the lack of scientific teaching methods, and the lack of self-reflection over the poor evaluations. We need to better manage the teachers with regard to the assessment results, the selection process of who will be assessed, and the scientific selection of assessment items, the finding shows. I hope my research will contribute to developing the basic materials of lecture-assessment systems.

This study was conducted just like a report as a material to be used in making the safety manuals, using the word, “Ski helmet”, based on the urgency of the study in providing the insight into what people’s perception of ski safety is like. As for the research methods, I tried to reach the conclusions through the observations and interviews with teachers and learners who took part in college ski courses, those working for the ski gear rental agency, and those conducting safety patrols. The research conclusions could be derived from each situation that I faced when conducting the interviews and other information acquired from the fields. AS for the awareness of ski safety, as only 45.2% skiers wear helmets, the safety awareness about ski is not so high in Korea. The reason they don’t wear the safety gears like helmets is that they feel it uncomfortable to wear them, having no experience of any safetyrelated incidents and the subsequent insensitivity to safety. My conclusion is that it is very important that the teachers teaching ski skills must show their own habits of wearing safety gears to the students before making it obligatory for them to wear them while skiing, which is the best way to improve the safety in ski fields.

This study started to look into how Taekwondo gyms can overcome the management crisis. To do so, I used the theories from the study of failures established by Hatamura Yotaro in 2002, which is to find out what created the failures, rather than how to succeed. The study methods include surveys on study participants, along with the interviews with them, which gets mixed with explanatory designs. The results go as follows. First, as for the reason why they fail, they should look at the instructors’ motivations, characteristics, and the subsequent management outputs. Second, as for the contexts of failures, they can understand why they failed if they structurize the failures and generalize the factors of failures. Third, as for the reason why the failures repeat, the instructors fail to expect the structures and contexts of failures so that they repeat which can have a kind of spiral pattern. They need to pay a particular attention to this. Fourth, as for the successful management methods, I proposed the law of three out of one thousand times, the pitfall of failures, the detailed plans to prevent failures, and simulation for problem-solving practices.

This study tries to show the findings of case studies of sport-related injuries in fitness centers whose popularity is ever-increasing, especially regarding the causes of such injuries, a field that lacks in-depth researches. As for the research methods, I made visits to three fitness centers, giving questionnaires to 100 members of the centers who have had sport-related injuries, which asks about why such injuries, under what circumstances, occurred, along with which parts of the body were hurt and how they treated them. I also conduced interviews with expert groups who work as professional trainers to add up the validity of this research"s findings. The research findings were summarized into the three like the below, other than the factor that most of the injuries could have been prevented with due diligence being paid to the sport scenes. First, subjects lack the knowledge and technologies without due process of education about the knowledge and technologies. Second, they repeatedly forget the significance of trainers" education by doing indiscreet behaviors. Third, some of them are overly motivated to engage in the sports even though they are not physically prepared well. Apart from the main concern of this study, it is mentioned that there are some legal matters between fitness trainers and users in regards to the injuries. I hope this study will contribute to enhancing the awareness of how the sports injuries can be dangerous among the users and of how to prevent such injuries among the trainers.

This study started from the recognition that, in spite of their tremenuous importance, no pre-arranged measures or manuals exist for emergent situations and proper safety measures in Taekwondo gyms. The study was conducted through the questionairs filled out by Taekowndo instructors and interviews with specialists. As for the accident cases, the major criteria of the study are the environmental accidents such as fires in locker rooms and injuries from the glass doors, the epidemic illnesses between students, the accidents happening on the way home after the training, and the accidents resulting from the negligence of duty in the teachers’ side. As for the problems in the preventive measures, the major criteria of the study are the poor awareness of safety problems along with the subsequent mismanagement of safety procedures, the lack of safetry-related education, and the lack of safety-related standard procedures.
