  • 이 연구는 스포츠이벤트 개최의 본질적 한계와 문제점을 비판적 관점에서 조망하여 미래지향적 시선을 설정하는 데 목적이 있다. 연구흐름의 초입부분에 스포츠개최에 열광하는 이유와 정당성을 살펴보았고, 이에 따른 체육학계의 움직임을 검토하였다. 즉 스포츠이벤트의 개최 이유와 정당성은 이념적 정치논리를 근간으로 한 실용주의에 기인한다고 볼 수 있다. 따라서 선행연구의 흐름도 효용성의 범주에 매몰된 연구결과가 대부분이었다. 그러나 스포츠이벤트 개최는 경제적 기대와 효과측면에서 본질적 한계가 내재함을 알 수 있었다. 한국사회뿐만 스포츠이벤트 개최의 효용성 등식은 일종의 최면효과에 의한 착시현상으로 간주된다. 따라서 지속가능한 미래 스포츠이벤트 개최의 안목은 인식의 틀을 해체시킬 수 있는 비판론자의 주장들이 누적되어 균형을 유지하고, 사회적 합의로까지 확산될 때 스펙트럼이 넓어질 것이다. 즉 또 다른 시선인 비판적 접근은 냉철한 현실적 판단을 환기시킴으로써 맹목적인 수용에 의한 부작용을 최소화시키는 데에도 기여할 것이다. 이와 함께 선진화된 스포츠문화의 의식으로써 스포츠컬처리즘의 지향, 성장과 분배의 문제를 관통하는 통합적 시선, 정치철학으로서의 로컬 거버넌스 등이 상호 연결되고, 에너지가 결집될 때 스포츠이벤트 개최의 합리적 선택이 가능하게 될 것이다.

  • 본 연구의 목적은 당구 숙련자와 비 숙련자를 대상으로 당구 스트로크 시 근활성도와 뇌파를 비교 분석함으로써 두 집단 간의 차이를 규명하여 객관적이고 과학적인 데이터를 통해 당구의 효과와 효율적인 훈련 방법을 위한 기초 데이터를 제시하는데 있다. 연구결과 숙련자와 비숙련자간에 근활성도에는 유의한 차이가 나타나지 않았으며 뇌파에서도 유의한 차이가 나타나지 않았다. 따라서 당구 스트로크 시 숙련자와 비숙련자 간의 근활성도와 뇌파에는 긍정적인 영향을 미치지 않은 것으로 확인되었다. 이러한 원인은 연구대상자의 부족, 일회적인 실험, 그리고 심리적 및 생리적인 실험 통제를 완전히 하지 못했기 때문이라고 생각되며 이와 관련하여 본 연구에 대한 기전을 보다 명확하게 밝히기 위해서는 추후 생리 및 심리적인 실험통제가 이루어진 상황에서의 연구가 이루어져야 할 것으로 사료된다.

  • OBJECTIVES : Schizandra chinensis is well known for its efficacy at liver function reinforcement, relieving thirst and recovery from fatigue. In this study, we examined the effects of sports drink containing Schizandra chinensis on serum metabolic substrate, electrolyte, stress indicators, related-enzyme and exercise performance, rectal temperature, and heat shock proteinb70 (HSP70). METHODS : Elite long-distance runners (male, 21.3yrs, n=16) were selected and divided into two groups; an experimental group (EXP, n=8) and a control group (CON, n=8). A beverage containing Schizandra chinensis was supplemented 3 times per day to EXP for 4 weeks. Serum biochemical elements (glucose, lactate, total cholesterol, triglyceride, high density lipoprotein cholesterol, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, creatinine, creatine phosphokinase, lactate dehydrogenase, blood urea nitrogen, Na, K, Cl) were analyzed by auto blood analyzer. Exercise performance was measured by treadmill exercise test, HSP70 was detected by electrophoresis and Western blotting, and rectal temperature was measured by rectal temperature probe. RESULTS : Administration of the beverage increased significantly the rest level of blood Na, Cl and glucose and decreased significantly lactate dehydrogenase, glutamate oxaloacetate transaminase. No difference was found in exercise performance, rectal temperature increment or HSP70 concentration between groups. CONCLUSIONS : Administration of a sports drink containing Schizandra chinensis altered blood glucose, lactate dehydrogenase, glutamate oxaloacetate transaminase, Na and Cl levels.

  • This study was conducted to examine the possibility of Salicornia herbacea L. powder as a functional food beneficially affecting carbohydrate metabolism and antioxidant capacity. Twenty-four, 6-week old, maleSprague-Dawleyrats were classified into three groups: normal diet control (CON), high-fat diet control (HFC) and high fat diet + Salicornia herbacea L. (SHF). Related feed was provided to each group for 4 weeks. Weight gain rate increased most in the HFC rats, and the concentration of glucose was significantly high in both the HFC and SHF groups, compared to the CON group. The SHF group showed a significantly high expression rate of Glut 4 (21.36%), compared to the CON and HFC groups. The glycogen content in muscle was significantly high in both the HFC and SHF groups, compared to the CON group. There were significant differences in the malondialdehydecontent in muscles between the groups, with the content in the CON and HFC groups being significantly higher than the SHF group. All the groups showed a similar tendency to each other in the liver tissue as well. Concerning the expression of Cu,Zn-super oxide dismutase andglutathione peroxidaseproteins, the SHF group was significantly higher than the CON and HFC groups. Overall, the experiment result above implies a possibility that an intake of Salicornia herbacea L. powder can regulate weight by decreasing the weight gain rate, further suggesting its effectiveness as a functional food before exercise by increasing the energy storage capacity and antioxidant capacity.

  • This study was designed to investigate the effects of vitamin E supplementation on radical scavenger activity and immune responses in female judo athletes(n=18). The age and sex matched sedentary students were used as controls(n=15). The initial plasma vitamin E concentration, lipid peroxide level and radical scavenger activity (RSA) were not different between two groups. The supplementation of $\alpha$-tocopheryl acetate(400IU/d) for 4 weeks significantly increased plasma vitamin E concentration of the subjects in both groups. In addition, the decrease in thiobarbituric acid reactive substance(TBARS)(p<0.05) and enhancement of RSA(p<0.05) were observed in both groups. Percentages of total T-cells in the athletic group was lower than that in the control group(p<0.05). However, the ratio of CD4 / CD8(helper T-cal $l^pressor T-cell) was higher in the sports group, due to more decrease in CD8 subset than in CD4 subset. The concentrations of IgG and IgM in the sports group were significantly lower than those in the control group(p<0.05). Therefore, severe training of the athletic group seems to be associated with the changes of supplementation. In conclusion, vitamin E supplementation (400IU/d, 4 weeks) of the female university students improved antioxidative activities of the blood, by decreasing lipid peroxide and enhancing radical scavenger activity. Percentages of T lymphocytes and IgG and IgM concentrations in the athletic group were lower than those in the control group. Meanwhile, vitamin E supplementation had no effects on immune status in both groups.ps.

  • The purpose of this study was to investigate the effects of turmeric intake and weight training on blood alcohol concentration, liver enzyme levels of and their effects on health promotion in adult males. There was no significant difference of taking turmeric powder combined with weight training exercise on blood alcohol levels in adult men who consumed alcohol on a regular basis. There was also no change on the change of body composition. The results were collected from elite athletes that had spent more than 10 years in their respective sports so it is difficult to observe any significant results from 8 weeks, short-term exercises of 1RM 70~80%, 3 times per week. In the next study, it is necessary to divide the subjects into more diverse groups and subject them by varying amounts of turmeric intake, exercise, etc., in order to fully study and understand the effects on blood alcohol level, change, and health promotion. Consequently, this study demonstrated there were no significant differences in the effects of continuous drinking habits of adult men's turmeric powder intake and weight training exercise on changes in GOT, GPT, γ-GTP, and blood alcohol concentrations. Moreover, health improvements themselves didn't affect changes in body composition.

  • [Purpose] The combined effect of different types of post-exercise treatment has not been fully explored. We investigated the effect of combined cold water immersion (CWI) and compression garment (CG) use after maximal eccentric exercise on maximal muscle strength, indirect muscle damage markers in the blood, muscle thickness, and muscle soreness score 24 h after exercise. [Methods] Ten men performed two trials (CWI + CG and CON) in random order. In the CWI + CG trial, the subjects performed 15 min of CWI (15℃), followed by wearing of a lower-body CG for 24 h after exercise. In the CON trial, there was no post-exercise treatment. The exercise consisted of 6 × 10 maximal isokinetic (60°·s-1) eccentric knee extensions using one lower limb. The maximal voluntary contraction (MVC) and maximal isokinetic (60°·s-1) strength during knee extension, as well as the indirect muscle damage markers, were evaluated before exercise and 24 h after exercise. [Results] The maximal muscle strength decreased in both trials (p < 0.001), with no difference between them. The exercise-induced elevation in the myoglobin concentration tended to be lower in the CWI + CG trial than in the CON trial (p = 0.060). The difference in the MVC, maximal isokinetic strength, muscle thickness, and muscle soreness score between the trials was not significant. [Conclusion] CWI followed by wearing of a CG after maximal eccentric exercise tended to attenuate the exercise-induced elevation of indirect muscle damage markers in the blood.

  • Maternal zinc deficiency is relatively common worldwide, but its consequences for pregnancy outcome are not established. The purpose of this study was to examine the effect of zinc status in the second trimester on pregnancy outcome. Subjects were 248 pregnant Korean women (25-28 wk gestation). Cord blood was collected from subgroup of 69 women and pregnancy outcome data were obtained from 185 babies. Anthropometry measurement, dietary intake, and biochemical characteristics of pregnancy and cord serum substances were measured. The subjects were divided into quartiles on the basis of maternal serum Zn concentration; $ZnQ_1$ (< 25 percentile), $ZnQ_2$ ($26\~50$ percentile), $ZnQ_3$ ($51\~75$ percentile), and $ZnQ_4$ ($76\~100$ percentile). Zn groups were compared in terms of various maternal factors, concentrations of cord serum substances, and pregnancy outcome. Maternal serum Zn concentration was $118.4\;{\pm}\;35.5\;{\mu}g/dl$ as mean. Intake of Zn was lower than Korean RDA. The rate of Zn deficiency among all subjects was $8.5\%$. Maternal serum Zn levels belonged to normal range. Cord serum Zn level was about $154.7\%$ of maternal serum level. Intakes of energy, calcium, iron, folic acid, and riboflavin did not meet the Korean RDA for pregnant women by gestational age. The mean birth weight of neonates is 3083 $\pm$ 697 g, of whom $9.1\%$ were of low birth weight (< 2,500 g). Maternal serum Zn level was positively correlated with pre-pregnancy weight, pre-pregnancy body mass index, and vitamin C intake (p < 0.05). $ZnQ_1$ group had significantly lower maternal serum iron concentration and higher cord serum cholesterol than those in other groups. Maternal serum Zn level, cord serum Zn level, and dietary Zn intake were no related to the pregnancy outcome. The birth weight had a correlation with the maternal hemoglobin and albumin concentration. In conclusion, at this study, we could not find the association with maternal Zn status in 2nd trimester and pregnancy outcome.

  • The purpose of study to phenomenological examine and the mechanism regarding the gene(DNA, RNA, Protein) and sports to studied, analyzed. and evaluated. This review considers the evidence for genetic effects in several determinants of endurance performance and resistance performance, namely: body measurements and physique, body fat pulmonary functions, cardiac and circulatory functions, muscle characteristics. substrate utilization, maximal aerobic power and other. Moreover, the response to aerobic training of indicators aerobic work metabolism and endurance performance is reviewed, with emphasis on the specificity of the response and the individual differences observed in training ability. This study indicate that improvement of 'Enhancer Action' in RNA genes changed by exercise or sports. Moreover exercise was effect on Central Dogma with DNA makes RNA makes Protein. and think that occurred with exercise influence on skeletal muscle into cell have to Myosin Heavy Chain (MHC) changed was after exercise performance, which accompanied into skeletal muscle that were exercise-induces gene-modulation that is, take gene mutations. This study known that existed hormone(epinephrine)-immune system with interaction. Exercise were altered insulin binding and MAP Kinase signaling increased into immune cells. This review suggested that the high rate of glutamine utilization by cells of the immune system serves to maintain a high intra cellular concentration of the intermediates of biosynthetic pathways such that optimal rates of DNA, RNA and protein synthesis can be maintained. In the absence of glutamine, lymphocytes do not proliferate in vitro: proliferation increase greatly as the glutamine concentration increase. Glutamine is synthesized in skeletal muscle. Skeletal muscle and plasma glutamine levels are lowered by sepsis, injury, bums, surgery and endurance exercise and in the overtrained athlete. The study of result show that production of ET-1 is markedly increased tissue specifically in the heart by exercise without appreciable changes in endothelin-converting enzyme and endothelial receptor expressions, suggest that myocardial ET-1 may participate in modulation of cardiac function during exercise. Conclusionally, this study indicate that improvement of 'Enhancer Action' in RNA genes changed by exercise or sports. Moreover exercise was effect on Central Dogma with DNA makes RNA makes Protein. This study is expected to contribute the area of sports science, medicine, hereafter more effort is required to establish the relation between gene alters and exercise amount.
