Childhood obesity causes a higher risk of obesity, premature death and disability in adulthood. In addition, obese children experience an increased risk of respiratory problems, hypertension, cardiovascular disease, insulin resistance and psychological effects. This study aimed to investigate how an exercise intervention affects health-related physical fitness and inflammatory-related blood factors in obese children after. We hypothesized that there would be positive effects on serum levels of insulin-like growth factor-1 (IGF-1), connecting peptide(C-peptide) and resistin, as well as in muscle and cardiovascular-related physical capacities, after an exercise intervention in obese children. Thirty-seven obese children haveperformed health-related fitness tests and provided blood samples for the analysis of changes in circulating biomarkers, both before and after an 8-week exercise intervention, which includes stretching, aerobic exercise, resistance exercise and sports games. The results indicate that exercise training beneficially affects body compositions, especially percentage body fat and muscle mass, without influencing to body weight and height. The results of the physical fitness tests show that muscle and cardiovascular capacity were increased in obese children in response to exercise training. Simultaneously, the exercise training decreased circulating levels of C-peptide, which equated to a "large" effect size. Although there were no significant effects on the levels of IGF-1 and resistin, they show a "small" effect size. Therefore, our findings suggest that the exercise intervention have beneficial effects on body composition and physical fitness levels in obese children, whichmight be associated with the decline in circulating C-peptide.

Background: Physical therapy applied to stroke patients is recognized as a treatment that promotes function recovery, and it is a widely known fact that constant exercise should be performed. However, there are insufficient studies on exercise intensity and exercise time that can minimize side effects and maximize function recovery for exercise therapy. Objectives: To determine the effect of exercise variables on CPK generation during aerobic exercise in stroke patients and to discover how to use appropriate exercise intensity and time when conducting an exercise for function recovery in stroke patients. Design: Quasi-experimental research. Methods: This study classified subjects into three groups (low-intensity exercise group: LIE, moderate-intensity exercise group: MIE and high-intensity exercise group: HIE) according to exercise intensity, and was further classified into two groups (10-minute exercise group: 10MG and 20-minute exercise group: 20MG) according to exercise time variables within each exercise intensity group. After, the change in CPK according to exercise intensity and time was confirmed through hematological analysis. Results: In LIE and MIE, the CPK blood concentrations before and after exercise were increased in 10MG and 20MG, which was not statistically significant (P>.05). In HIE, the CPK blood concentrations before and after exercise were increased in 10MG, and it was statistically significant (P<.05). In HIE, the CPK blood concentrations before and after exercise were increased in 20MG, and it was statistically significant (P<.01). In 10MG and 20MG, the CPK blood concentrations before and after exercises were increased in all intensity group, and there was a statistically significant difference only in HIE. Conclusion: From the results of this study, considering CPK, it will be helpful to recover and improve function if the exercise intensity setting is applied in the type of moderate intensity exercise during physical therapy interventions in stroke patients.

This study examined the effects of group exercise program on health conditions and quality of life in cerebral palsy. Adults with cerebral palsy in their 20's who participated in the evaluation of measurement tools prior to and following the experiment. The control group was engaged in manual exercise for the range of joint movement and extension exercise for arms, legs and trunk, and experimental group performed group exercise program including boccia exercise. The health condition and quality of life of the experimental group were significantly increased after intervention (.05<). There was a slight increase in the control group, however it was not statistically significant. As a result of comparing the health condition and quality of life of the two groups, the value of the experimental group was significantly higher than that of the control group. The results of this study suggest that exercise programs for patients with cerebral palsy in the twenties are considered as beneficial interventions to improve health conditions and quality of life.

In this study we investigated effects of supplementation with ethyl acetate extracts of the brown alga Eisenia bicyclis on innate immune cells to evaluate the possibilities as an immunomoulator in exercise stress. Twenty male SD rats were divided into four groups and the treatments were as follows: A, no Eisenia bicyclis extract (EBE) (200 mg/kg) intake and maintained at rest ; B, no EBE intake and undergoing exercise ; C, EBE intake and undergoing exercise ; D, EBE intake and maintained at rest. After 5 weeks of oral supplementation, rats were undergoing intensive swimming exercises for 2 h and sacrificed to assess the effects on peritoneal macrophages, spleen cells and natural killer (NK) cells. We showed increasing effects on nitric oxide-inducible nitric oxide synthase (NO-iNOS) production by macrophages and no effects of NK tumoricidal activity and suppressive effects on spleen cell proliferation in exercise group. However, EBE supplementation suppressed NO-iNOS production by macrophages and increased NK tumoricidal activity and spleen cell proliferative response to mitogen in exercise group. Overall, these results that EBE supplementation has differential effects on innate immune response and could be useful as sports nutrition.

Purpose: This study was conducted in order to closely examine the effects on bone mineral density and health promotion behaviors following the intervention of a 20-week Thera band exercise program targeting elderly women. Methods: This study is a pseudo-experimental research with a pre-and-post design in a single group that examined the effects after the intervention of Thera Band Exercise for 20 weeks targeting 31 elderly women over 60 years of age who visit a Senior Welfare Center located in K city. It analyzed subjects' general characteristics using error and percentage, health promotion behavior, and a bone density aspect using the mean and standard deviation, as well as a change in the health promotion behavior and bone density, before and after exercise with Paired t-test by using the SPSS 18.0 program. Results: The effect of the Thera band exercise program on bone mineral density was reduced (t=8.140, p<.001) gradually after 20 weeks of exercise compared to the pre-exercise period. The health promotion behavior before and after exercise showed the significantly increasing outcomes (t=3.26, p=.003). Conclusion: There is a limitation to a direct rise in bone mineral density with the use of Thera band exercise intervention in the elderly. A change in health promotion behavior before and after exercise increased significantly. Thus, it was confirmed that taking exercise leads to a gradual rise in health promotion behavior. Hence, it understood that continuous exercise is useful and brings about a positive change in promoting health maintenance in elderly women.

Physical activity is one of important factors of the chronic disease. It was reported that Most of Korean workers didn't take exercise regularly. The purpose of this study is testing effects of exercise program, based on the Theory of Planned Behavior. 30 subjects participating in this study are workers in small enterprises and have not taken exercise regularly. Exercise program, which includes education, support, monitoring, and counseling, was conducted for 6 weeks. Effects of this program was evaluated by the change of exercise, attitude, subjective norm, perceived control. intention of exercise, perceived health states, and fatigue. The results of this study can be summarized as follows: 1. There was the significant difference between pre and post-test in the subjective norm, perceived control. and intention of exercise, but not the significant difference in the attitude of exercise. 2. 53.3% of the subject of this study had taken exercise regulary in the post-test. 3. There was not the significant difference in the perceived health states and fatigue, From the results, it can be concluded that the exercise program is effective, leading to the change of intention and exercise rate. On the other hand, it was not effective in Physiological aspects. It seems that these result was due to short term program. Thus, it can be recommended that studies are needed with longer term program and larger sample.

PURPOSE: This study examined the effects of exercise of diverse intensities on the recovery of articular cartilage in osteoarthritic rats. METHODS: Over a period of four weeks, the authors applied treadmill exercise programs of diverse intensities to Sprague-Dawley rats, to which intra-articular injection of monosodium iodoacetate(MIA, 3mg/$50{\mu}l$, diluted in saline) was applied to the right knee joint to induce osteoarthritis. The four-week exercise program was not carried out with the control group(CG, n=10). Exercise programs of applicable intensities were applied to the low-intensity exercise group(LEG, n=10), moderate-intensity exercise group(MEG, n=10), and high-intensity exercise group(HEG, n=10) over the four weeks. Observations were made of morphological changes in the rats' articular cartilage, using hematoxylin and eosin stains. RESULTS: there were significant differences(p<.05) in the comparison of articular damage scores between the four groups involved. Articular cartilage damage scores were found to be significantly lower in the LEG, MEG, and HEG than in the CG, indicating that exercise helped with the recovery of cartilage. Of these latter three groups, the MEG showed the highest level of recovery, while the HEG showed the lowest. CONCLUSION: These study results suggest that exercise is effective in treating OA. They also indicate that in prescribing exercise to treat osteoarthritic patients, exercise of moderate intensity is most suitable to patients' physical conditions, rather than low or high intensity, maximizes, and so should be used to maximize the effects of therapy.
