This study purposed to prove the effect of exercise after induction muscle atrophy related Apoptosis gene Bcl-2 m-RNA, Bax m-RNA, Caspase-3 m-RNA We classified the mice(ICR) after induction muscle disuse atrophy into 2 groups: exercise(20 mice) and non-exercise(20 mice). the analysis point of view which if follows is stability, one day, three day, five day, seven day and each testing group three mice cervical decapitation which will burn the killed related apoptosis gene the Bcl-2 m-RNA expression showed a significant statistical difference in non -exercise group'1st day and 7st day(p<.001, p<.01). There was a significant difference in exercise group'5st day(p<.01). The Bax m-RNA expression showed a significant statistical difference in non -exercise group'3st day and 7st day(p<.001). When stabilized, there was little significant difference in non -exercise group'1st day and 5st day. The Caspase-3 m-RNA expression showed a significant statistical difference in non -exercise group'3st day, 5st day and 7st day(p<.001). When stabilized, there was little significant difference in non -exercise group'1st day. It could be inferred from the results of the study that a steady in crease load training method can be more effective than continued stability after patients who have the muscle atrophy which appear from an accident or a bed safety muscular power exercise insufficiency treat. Bcl-2 m-RNA expression that inhibits cell death didn't have much effect. But, Bax, Caspase-3 m-RNA that promotes cell death showed a significant statistical increase.

This study investigated the effects of riding for the disabled program on body composition and obesity-related gene expression. The handicapped 20 people divided into two groups, the result of a targeted examination of body composition and obesity-related genes that change after 16 weeks riding for the disabled program Body composition in fat mass, muscle mass, body fat percentage, both were confirmed a significant difference in the riding for the disabled program, obesity-related genes were able to confirm the significant differences in adiponectin and PPARa except for PPARγ. Rehabilitation of 16 weeks riding the body composition and obesity are related to people with disabilities to be able to confirm a positive difference in gene expression riding for die disabled program feed movement that can prevent obesity and improve.

김재호(Kim, Jea-Ho),고영준(Ko, Young-Jun),조원제(Cho, Won-Je) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.4

In this study, male adults were asked to perform a 6-weeks high intensity resistance exercise to observe the changes in testosterone, IGF-1 and blood inflammatory factors(CRP, CPK, IL-6) by exercise intensity and period. The male students in their 20’s who are currently attending the D university located in Y-si, Gyeonggi-do were participated in this study. 10 participants were assigned into a control group(CG), 10 participants were assigned into intense resistance exercise group(RTG). The participants were asked to perform the exercise for a 6-week short, 3 times a week. No exercise was given to control group. The intense exercise group was asked to perform 5 sets 70-80%RM, 3 to 8 repetitions per a set. Repeated measure ANOVA SPSS Ver. 18.0 statistics program was used to describe all data statistically. Then Repeated measure ANOVA was performed to confirm the group, period and interaction, whereas paired t-test was used to validate the difference between the groups by time. And different between CG and RTG was independent t-test after exercise treatment. As a result, the significant difference was shown on IGF-1, blood inflammatory factors in RTG pre to post. The difference in IL-6 was observed between the groups. The interaction was observed in blood inflammatory. So In correlation analysis about testosterone, IGF-1 and inflammatory factors after the short-term high-intensity resisted exercise, CPK and IL-6 showed positive correlation. Therefore, high intense resistance exercise was shown to have a positive impact on IGF-1, blood inflammatory factors, the exercise needs to be carefully prescribed considering the individual characteristics.

김재호(Jea-Ho Kim),전용균(Yong-Kyun Jeon),이동복(Dong-Bok Lee) 한국생활환경학회 2010 한국생활환경학회지 Vol.17 No.2

The purpose of this study is to examine the effective exercise intensity for the prescriptions between people of normal weight and who are obese. Selected for the purpose of the study were 10 male residents (age, 23±2.2 years) of Seoul. The participant are normal weight rage whose % Body fat is less than 20% and 10 male residents who were considered obese with %Body fat of 23%~30%. In the first test, the participant walked on the treadmill using Bruce protocol until they were all-out to get the maximal oxygen consumption. In the secondary test, in order to calculate %VO₂R by exercise intensity corresponding to the each subject's exercise intensity level of 30%VO₂R, 35% VO₂R and 40%VO₂R, %VO₂R formula (%VO₂R=%VO₂max-(1MET=3.5 ㎖/㎏/min)×Ratio+%VO₂rest) was applied the maximal oxygen consumption which was gained from the fist test. And then, the intensity wan adjusted manually. During the 30-minute experimental procedures the respiratory exchange rate (RER) was within 0.7~1.00. The results were explained below. Firstly, during the sub-maximal exercise, based on the intensity and the participant's %Body fat, significant differences in the rate of breathing could be observed within, and between the two groups, at exercise intensity of 30%VO₂R, 35% VO₂R and 40%VO₂R (p<.001). Secondly during the sub-maximal exercise, the calories burned by the group of normal weight, whose ability for oxygen intake is greater than the obese group was significantly higher (p<.001). Thirdly, when the rate of fat consumption and that of burning were compared between the two groups during the sub-maximal exercise, both groups showed significant result at the exercise intensity of 30%VO₂R and 35% VO₂R (p<.01), and also at the intensity of 40%VO₂R (p<.001). Fourthly during the sub-maximal exercise based the intensity and %Body fat, no significant differences were apparent at the exercise intensity of 30%VO₂R, hoewer, at the exercise intensity of 35% VO₂R the result in the normal weight and the obese, showing significant differences (p<.01), and at the 40% VO₂R the results were even more significant (p<.001). Fifthly, during the sub-maximal exercise based on the intensities and %Body fat, there were significant differences in the heart rate and heart beat at different exercise intensity (p<.001). As a result, in order to develop and prescribe a suitable exercise regimen, it is important consider many factors such as age, sex and individual physical abilities.
