본 연구의 목적은 장기간의 지구성 운동 또는 저항성 운동이 중년 흰쥐의 골격근 내 단백질 합성과 분해에 미치는 영향을 규명하는 것이다. 50 주령의 male Wistar rat 30 마리를 이용하여 3집단(좌업, 지구성 운동집단, 저항성 운동집단)으로 무선배정한 후 12 주간 처치를 실시하였다. 연구결과 12주간의 저항성운동은 중년 쥐의 족저근 내 Akt/mTOR 신호전달체계를 활성화시켰고, FoxO1/MuRF1 단백질 발현을 저해하였다. 지구성 운동은 mTOR 신호전달체계에는 영향을 미치지 않았으나 FoxO1/MuRF1 단백질 발현을 저해하였고, AMPK/PGC-1α 발현을 증가시켰다. 요약하면 12주간의 운동트레이닝은 중년 흰쥐의 골격근 내 단백질 동화/이화반응에 긍정적인 영향을 미쳤으며, 지구성 운동은 근단백질 이화반응의 저해를 통해서 노화근육의 단백질 균형에 영향을 미치는 것으로 나타났다. 이러한 결과를 통해서 근 손실에 따른 근 기능의 저하가 가시화되기 시작하는 중년을 대상으로 실시되는 운동처방 시 근 감소증 예방 및 치료를 위해 저항성 운동만이 아니라 중강도 이상의 지구성 운동도 유효할 것으로 생각된다.

Purpose : Patients with Parkionson's disease have a temporal and spatial restriction for their's exercise treatment. The aim of this study is to verify the effectiveness of e-exercise program on balance, gait, and endurance ability in people with Parkinson's disease. Methods : Eighteen participants, with Parkinson's disease that ranged from stage to on the Hoehn & Yahr scale, were assigned to two group. Two group were divided into on-line group that exercised in home by computer video, and off-line group that exercised in clinical center. Exercise program that included 3 sections (warm-up, main exercise, cool down)-5 parts(stretch, strength, balance, gait, stretch) was used to train for participants. We used the functional reach test for balance ability, timed up and go test for gait ability, 6 minute walking test for endurance ability. Wilkoxon sign lank tests were used to assess the difference of balance, gait, and endurance ability in pre-and post test each groups. Mann-whitney tests were used to assess the difference of balance, gait, and endurance ability between groups. Results : Wilkoxon sign lank tests revealed that both group were improved the balance, gait and endurance agility by e-exercise program intervention. Mann-whitney tests showed that there were no differences between groups in the variation of balance, gait, endurance ability. Conclusion : We believe that exercise program with on-line(e-exercise program) is an effective intervention for people with Parkinson's disease and is no different than off-line exercise group in the variation of balance, gait, endurance ability.

Purpose : This study purposed to analyze how dynamic stabilization exercise on an unstable surface, and static stabilization exercise on muscle strength and endurance. Methods : For this study we sampled 9 people for the unstable surface dynamic stabilization exercise group, 9 for the stable surface static stabilization exercise group, and 9 for the control group. In order to examine muscle strength and endurance, we measured changes in the maximal voluntary isometric contraction (MVIC) using a dynamometer before, 3 weeks after, and 6 weeks after the experiment. Results : First, with regard to change in muscle strength, flexion strength showed a significant change in interaction by time (p<0.05). Extension strength showed a significant change in interaction by time (p<0.05). Second, with regard to change in endurance, flexion endurance showed a significant change in interaction by time (p<0.05). Extension endurance showed a significant change in interaction by time (p<0.05). Conclusion : In conclusion, this study confirmed significant changes in interaction between the groups and by time with regard to changes in muscle strength and endurance. These results suggest the potential of surface dynamic stabilization exercise as a clinical intervention.

We examined the effects of the NADPH oxidase p22phox C242T polymorphism on endurance exercise performance and oxidative DNA damage in response to acute and chronic exercises. One hundred three subjects were recruited, among which 26 healthy subjects (CC: 12, TC: 12, and TT: 2) were studied during rest, exercise at 85% $VO_2max$, and recovery before and after 8 weeks of treadmill running. Lymphocyte DNA damage increased significantly in response to exercise (p < 0.05). There were no significant differences in plasma MDA, SOD concentrations and lymphocyte DNA damage between CC genotype and T allele group, but significant endurance training differences were observed. Endurance training increased exercise time to exhaustion in both the CC genotype and T allele groups (p < 0.05) but no significant difference was found between groups. The results of the current study with young, healthy, Korean men are interpreted to mean that 1) the majority had the CC genotype of the NADPH oxidase p22phox C242T polymorphism (82.5%: CC, 15.5%: TC, 1.9%: TT), 2) acute exercise increased lymphocyte DNA damage, 3) endurance training significantly increased exercise time to exhaustion, and alleviated lymphocyte DNA damage, and 4) The NADPH oxidase p22phox C242T polymorphism, however, did not alter lymphocyte DNA damage or exercise performance at rest, immediately after exercise, or during recovery.

This study assessed the amount of energy consumed and fat deposition after endurance training in order to review the effect of 4-week endurance exercise on resting metabolic rate of a mouse during and after exercise and the effect of exercise. A total of 19 seven-week-old ICR male mice were used as the study subject. Those mice were divided into sedentary group (Sed) and trained group (Tr) after a week of environment adaption. The Tr group was trained with endurance exercise five times a week for four weeks. Weight and the amount of food intake were daily weighed and resting metabolic rate and metabolic rate after exercise were assessed before starting exercise and on the fourth week after training. Metabolic rate during exercise were measured four weeks after training. At the end of breeding period, statistically significant difference was shown in weights of trained and sedentary groups (p < 0.05). During a resting period, no significant difference was shown in oxygen intake, respiratory exchange ratio, and the amount of carbohydrate and fat oxidized. Moreover, no significant difference was shown in excess post-exercise oxygen consumption (EPOC) of an hour period after training. In contrast, the maximal oxygen uptake (VO₂ max) was approximately 11.1% higher in trained group after training compare to before. However, there was no significant difference in respiratory exchange ratio and carbohydrate and fat oxidization. During exercise, oxygen uptake, carbon dioxide production, and respiratory exchange ratio in energy metabolism during exercise showed no significant difference. However, significant difference was exhibited in the amount of fat oxidized in both groups. Summing up those results, endurance exercise could be concluded to be effective in weight control. However, weight loss is thought to be resulted from increase in fat oxidization during exercise unlike the conclusion made from previous studies where weight loss is prominently influenced by energy metabolism during a resting period and increased fat oxidation during post-exercise recovery. All experimental procedures were carried out at the Animal Experiment Research Center of Konkuk University. This study was conducted in accordance with the ethical guidelines of the Konkuk University Institutional Animal Care and Use Committee.

PURPOSE: The purpose of this study is to compare the effects of aerobic exercise and combination exercise on physical fitness, body composition, and depression and to observe the relationship between obesity and depression. METHODS: A total of 40 obese people were divided into an aerobic exercise group ($n_1$=20) and a combination exercise group ($n_2$=20) that was performed swiss ball exercise and aerobic exercise. Each group exercised three times per week for eight weeks. Outcome measures were basic physical fitness, body composition, and depression. RESULTS: After completion of the exercise, there was a significant difference in overall physical fitness factors of percentage body fat (%body fat), strength, muscle endurance, flexibility, cardiovascular endurance in the combination exercise group (p<.05). Strength, muscle endurance, flexibility, and cardiovascular endurance were more improved in the combination exercise group than aerobic exercise group (p<.05). However, changes of %body fat and psychological factor between the two groups were not significant. CONCLUSION: Combination exercise program has an effect on the solution of obesity in physical development and strength. Therefore, it seems to that use with better perform both aerobic exercise and Swiss ball exercise. In addition, the Swiss ball exercise, which is an easy, convenient and economical self-exercise that can be done at home, is recommended due to its positive effects on physical establishment and fitness.
