본 연구의 목적은 고지방식으로 유도된 비만이 에너지 항상성 조절인자인 신경영양인자와 섭식조절 호르몬인 렙틴 mRNA 발현에 어떠한 관련성이 있는지를 규명하는 것과 비만 쥐의 시상하부 BDNF 발현과 렙틴 리셉터 mRNA 발현, 혈청 렙틴과 항비만과의 관계에 대한 운동트레이닝과 정상식이로의 전환에 대한 효과를 확인하고자 하였다. 그 결과 8주 후 비만 대조군(HF)에 비해 운동군(HFT), 정상식이군(HFND), 운동 및 정상식이 트레이닝군(HFNDT)에서 각각 유의한 체중 및 혈중 TC 감소를 보였다(P<0.05). 혈중 TG에서는 HF군에 비해 HFNDT군에서 유의한 감소를 보였다(P<0.05). 혈중 렙틴은 HF군에 비해 HFT군에서 유의한 감소를(P<0.05), HFT군에 비해 HFND군에서 유의한 감소를 보였으며(P<0.05), HFND군에 비해 HFNDT군에서 유의한 감소를 나타냈다(P<0.05). 시상하부 BDNF 단백질 발현은 HF군에 비해 모든 군에서 유의한 증가를 보였다(P<0.05). 시상하부 렙틴 리셉터 mRNA는 HF군에 비해 HFT와 HFND군에서 약간의 감소를, HFNDT군에서는 증가를 나타내었다. 이상의 결과는 고지방식이로 유도된 비만쥐에 대한 운동트레이닝은 항비만 효과가 있는 것으로 나타났으며, 운동 또는 정상식이의 병행은 식욕과 체중조절에 최적의 비만예방 및 개선효과가 있을 것으로 사료된다. The purpose of this study is to examine how to relate with hypothalamus protein BDNF and mRNA leptin expression, and test the effect of exercise training upon anti-obesity in high-fat induced obese rats. Weight and plasma TC of the high-fat diet group (HF) significantly reduced in comparison to those in the high-fat diet and training group (HF-T), high-fat diet and normal diet group (HF-ND), and high-fat diet, training, and normal diet group (HF-ND+T) (P<0.05). Plasm TG of the HF group significantly decreased in comparison to the HF-ND+T group (P<0.05). The plasma leptin level significantly reduced in the HF-T group in comparison to the HF group, in the HF-ND group compared to the HF-T group, and the HF-ND+T group in comparison to the HF-ND group (P<0.05, respectively). All groups were significantly increased in hypothalamus BDNF protein expression in comparison to the HF group. In hypothalamus leptin mRNA expression, the HF-T and HF-ND groups reduced, but the HF-NF+T group increased in comparison to the HF group. This result suggests that it shows the effect of exercise training upon anti-obesity in high-fat diet induced obese rats and the combined exercise and/or normal diet may affect the optimal obesity improvement and prevention in appetite and weight control.

본 연구는 고지방 식이로 유도한 비만 마우스를 대상으로 규칙적인 운동과 식이변화에 따른 중추와 말초 조직에서 Endocannabinoid system(ECS)의 주요 구성인자인 monoglyceride lipase(MGL), fatty acid amidohydrolase(FAAH)의 변화와 그 수용체의 활성수준을 살펴보고, 규칙적인 운동으로 인한 개선 효과를 분자 생물학적 차원에서 규명하는데 목적이 있다. 본 연구의 실험동물은 4주령 된 수컷 C57/black mouse 40마리를 분양 받아 CO군(control, n=10)과 HF군(high fat diet, n=30)으로 분류하여 45%의 고지방 식이를 이용하여 6주간 비만을 유도하였다. 비만유도 후 HF군(n=10), HFT군(HF+training, n=10), HFND군(HF → normal diet, n=10)으로 재분류하여, 8주간 경사도 0°의 조건에서 주 5일, 1일 40분씩 트레드밀 운동을 실시하였다. 그 결과 HF군, HFT군, 그리고 HFND군은 CO군에 비하여 체중이 유의하게(p<0.05) 증가 하였으며, 시상하부의 CB1과 복부내장지방의 FAAH가 CO군에 비하여, HF군, HFT군 그리고 HFND군에서 유의하게 높게(p<0.05) 나타났다. 따라서 지속적인 고지방식이로 식욕통제와 지방대사에 악영향을 미치는 시상하부의 CB1과 복부내장지방의 FAAH가 증가하였음을 발견하였다. 8주간의 트레드밀 운동은 ECS에 긍정적인 영향을 미치지 못하였으며, 식이변화 역시 ECS에 긍정적인 영향을 미치지 못하였다. 따라서 향후 연구에서는 운동의 시너지 효과가 나타날 수 있는 고지방식이에서의 식이변화와 운동을 복합 처치한 디자인의 연구가 필요할 것으로 사료된다. This study was to investigate the effects of regulatory treadmill exercise on endocannabinoid system of adipose tissue and hypothalamus in high fat diet induced obesity mice. The adopted subjects of this study were 40 heads of four week old C57/black mice. Induced obesity through 6 weeks of a high fat diet while the other group were fed with a normal diet. After 6 weeks, all study mice were classified into 4 groups which were the control group(CO, n=10), high fat diet(HF, n=10), high fat diet-training(HFT, n=10), high fat diet-normal diet(HFND) groups. Treadmill running was performed during 40 minutes, 5 times a week for 8 weeks. The HF, HFT, HFND groups showed significantly(p<0.05) increased in body weight and significantly(p<0.05) higher CB1 receptor of the hypothalamus and FAAH of adipose tissue than CO group. Therefore, we found that the increase in CB1 receptor of the hypothalamus and FAAH of adipose tissue which is effects on the control of appetite and fat metabolism by continued high fat diet. However, treadmill training for 8 weeks and dietary changes did not have a positive impact on ECS system. Thus, in the future research, it is thought that the study will be needed showing the synergistic effect of exercise through combined treatment of dietary change and exercise in high fat diet.

The purpose of this study was to examine the effect of two different intensity of continuous exercise on magnitude of excess post-exercise oxygen consumption(EPOC), energy consumption following a 20min treadmill exercise. The subjects of this study were eight super-obesity in middle school students who were above 13 years old. subjects participated in two different exercise intensity to measure respiratory gas, blood lactate concentration and eardrum temperature. The results of this study were as follows: 1. The Energy consumption of the high intensity (80% VO₂ max) exercise group (264.68 35.60cal) was greater than that of the low intensity (50%) exercise group(172.01 20.39 Cal)(p<.001). 2. The EPOC of the high intensity exercise group (22.36+ 6.82Cal ) was greater than that of the low intensity exercise group(15.39+5.27 Cal)(p<.001). 3. The EPOC duration of th high intensity exercise group(28.36=3.56min) was longer than that of the low intensity exercise group(17.23+1.25min)(p<.001) 4. The blood lactate concentration, respiratory exchange ratio and temperature of the high intensity exercise group were greater than those of the low intensity exercise group(p<.05,p<.01). EPOC and duration were increase with 80%VO₂max, 80% VO₂max as intensity exercise got higher this also showed that it had something to do with lactate concentration in blood and increase of body temperature in the conclusion. We considered that there was a difference in using methods of energy, as there was a similar difference in RER. We though this following with oxygen consumption after exercise, we could clarify that high intensity exercise was better than lower intensity exercise in sametime for those who are obese especially adolescents to maintain their weights on the aspect of effect.

This research aims to develop a new evuluation method of endurance for elementary school students. The norm of the event of 1,000m running-walking was examined and reviewed. As a result, a new highly-valid norm for the present 1,000m running-walking was made. Among the 5th and 6th graders, 2,144 pupils were chosen. The subjects were given 1,000m running-walking and step test. The new norm led to the following results: 1. The frequency distribution of PEI according to Cajori's 5-stage evaluation method turned out to be normal for both 5th and 6th graders. In conclusion, this new norm of 1,000m running-walking is believed to provide more valid and credible scores for elementary school students. The 1,000m running-walking records and the PEI will be used as the basic data for foretelling one's endurance.
