The purpose of this study was to investigate the effects of combined exercise on irisin, body composition and glucose metabolism in obese elderly women with type 2 diabetes mellitus. The subjects were thirty-six obese elderly women with type 2 diabetes volunteers, aged 65 to 85 years, composed of the combined exercise type 2 diabetes mellitus group (n=20) and non-exercise type 2 diabetes mellitus group (n=16). The 60 minute combined exercise program (outdoor walking exercise & elastic-band exercise) was performed 3 times per week for 12 weeks. Exercise intensity of outdoor walking exercise was performed as medium intensity (RPE 5~6) and elastic-band exercise was progressively increased every four weeks (1-4 weeks: OMNI-RES 3~4, 5-8 weeks: OMNI-RES 5~6, 9-12 weeks: OMNI-RES 7~8). The results of the study in the combined exercise type 2 diabetes mellitus group were as follows; Irisin and skeletal muscle mass had significantly increased (p<.001), percentage of body fat had significantly decreased (p<.001). Further, HbA1c (p=.020) and fasting glucose (p<.001) was significantly decreased, and HOMA-β was significantly increased (p<.001). Correlation results showed that change of irisin had a significant negative correlation between percentage of body fat mass (r=-.423, p=.010), HbA1c (r=-.351, p=.036) and fasting glucose (r=-.424, p=.010). Also, irisin changes showed a positive correlation with aerobic endurance (r=.355, p=.034) and HOMA-β (r=.411, p=.013). In conclusion, the practice of regular combined exercise was found to increase the level of irisin in elderly women with type 2 diabetes and have a positive effect on body composition changes. In addition, HbA1c, fasting glucose and insulin secretion was improved, which helped to regulate glucose metabolism. Walking exercise and elastic band exercise are recommended as effective exercise for the prevention and management of diabetes in obese elderly women with type 2 diabetes mellitus.

[Purpose] Exercise can prevent conditions such as atrophy and degenerative brain diseases. However, owing to individual differences in athletic ability, exercise supplements can be used to improve a person's exercise capacity. Schisandra chinensis (SC) is a natural product with various physiologically active effects. In this study, we analyzed SC using a pharmacological network and determined whether it could be used as an exercise supplement. [Methods] The active compounds of SC and target genes were identified using the Traditional Chinese Medicine Database and Analysis Platform (TCMSP). The active compound and target genes were selected based on pharmacokinetic (PK) conditions (oral bioavailability (OB) ≥ 30%, Caco-2 permeability (Caco-2) ≥ -0.4, and drug-likeness (DL) ≥ 0.18). Gene ontology (GO) was analyzed using the Cytoscape software. [Results] Eight active compounds were identified according to the PK conditions. Twenty-one target genes were identified after excluding duplicates in the eight active compounds. The top 10 GOs were analyzed using GO-biological process analysis. GO was subsequently divided into three representative categories: postsynaptic neurotransmitter receptor activity (53.85%), an intracellular steroid hormone receptor signaling pathway (36.46%), and endopeptidase activity (10%). SC is related to immune function. [Conclusion] According to the GO analysis, SC plays a role in immunity and inflammation, promotes liver metabolism, improves fatigue, and regulates the function of steroid receptors. Therefore, we suggest SC as an exercise supplement with nutritional and anti-fatigue benefits.

The purpose of this study was to examine the effects of a cheonggukjang diet and aerobic exercise on lipid metabolism and antioxidant enzyme activity in rats. Thirty-two Sprague Dawley rats were randomized into a cheonggukjang diet with aerobic exercise (A), aerobic exercise (B), cheonggukjang diet (C), and control group (D). The cheonggukjang diet group consumed 20 g of 20% cheonggukjang a day with their normal diet. Exercise training consisted of treadmill running (25~40 min, 5 day/wk) and the exercise intensity was gradually increased. The results are as follows: T-C was significantly lower (p<0.05) in A compared to B and C. TG was significantly lower (p<0.001) in A compared to D. B and C were significantly lower than D. HDL-C was significantly higher (p<0.05) in C compared to D. LDL-C was not statistically different across the groups. Additionally, TBARS were not statistically different in the control or experimental groups. SOD was significantly lower (p<0.05) in A compared to D. C was significantly lower (p<0.05) that of D. CAT and GPx failed to reach the statistical difference between experimental and control groups. The major findings of this study were that aerobic exercise with a chenggukjang diet intervention improved lipid profiles and antioxidant capacity in this animal model. Therefore, a cheonggukjang diet and aerobic exercise will help to improve antioxidant capacity and prevent lifestyle related diseases.

The two groups classified that one group(EG) was done intermittent fasting and resistance exercise both, the other group(CG) was controled. The group of EG was applied doing intermittent fasting 1 time for 24 hours a week, and doing resistance exercise 3 times for 60 minutes a week. The intensity of the exercise was 60%. Each measurement variable measured before and after 12 weeks to investigate the effect. During this study got the result with this step. First, EG have shown small interaction with sex hormone. Second, EG have shown small interaction with resistance exercise. Therefore, this study give us positive result to effect of intermittent fasting and resistance exercise on sex hormone and glucose of middle-aged women for 12 weeks. However, it has limitation to verify effect of intermittent fasting and resistance exercise.

Objectives: We evaluated the anti-fatigue effects of Rh2-enriched Korean ginseng (Ginseng Rh2+) using a forced exercise-induced chronic fatigue mouse model. Methods: ICR male mice were subjected to running wheel for 1 h, 5 days/week during 4 weeks, and running velocity was gradually increased. Each running session was followed by oral administration of distilled water, Ginseng Rh2+ (150 or 300 mg/kg), or N-acetyl-L-cysteine (NAC, 100 mg/kg) 1 h later. The exercise tolerance and forced swimming test were performed to evaluate the fatigue condition. Results: Chronic forced exercise reduced the physical activity, as evidenced by the behavioral tests, which were notably ameliorated by Ginseng Rh2+ treatment. Ginseng Rh2+ treatment also attenuated the alterations of energy metabolism and oxidative stress in skeletal muscle tissues and/or sera, including malondialdehyde (MDA), lactate concentration and its related factors (lactate dehydrogenase, blood urea nitrogen, and glucose levels). Conclusion: These findings strongly suggest that Ginseng Rh2+ exerts a potent anti-fatigue effect through modulation of energy metabolism and oxidative response.

The peroxisome proliferator-activated receptor $\alpha$ (PPAR$\alpha$) is a nuclear transcription factor that plays a central role in lipid metabolism and obesity. Exercise also is a powerful modifier of the manifestations of the lipid metabolism and obesity in animal models and humans with obesity and metabolic syndrome. However, effects of exercise on lipid metabolism and obesity in normal-weight younger female subjects, having functional ovaries and not metabolic disease, remain unexplained. To explore the effects of exercise on the development of obesity and its molecular mechanism in high fat diet-fed female C57BL/6J mice, we experimented the effects of swim training on body weight, adipose tissue mass, serum lipid levels, morphological changes of adipocytes and the expression of PPAR$\alpha$ target genes involved in fat oxidation in skeletal muscle tissue of female C57BL/6J mice. Swim-trained mice had significantly decreased body weight, adipose tissue mass, serum triglycerides compared with female control mice. Histological studies showed that swim training significantly decreased the average size of adipoctyes in parametrial adipose tissue. Swim training did not affect the expression of PPAR$\alpha$ mRNA in skeletal muscle. Concomitantly, swim training did not increase mRNA levels of PPAR$\alpha$ target genes responsible for fatty acid $\beta$-oxidation, such as carnitine palmitoyltransferase 1, medium chain acyl-CoA dehydrogenase, enoyl-CoA hydratase/3-hydroxyacyl-CoA dehydrogenase, and thiolase in skeletal muscle. In conclusion, these results indicate that swim training regulates lipid metabolism and obesity in high fat diet fed-female mice although swim training did not increase mRNA levels of PPAR$\alpha$ target genes involved in fatty acid $\beta$-oxidation in skeletal muscle, suggesting that swim training may prevent obesity and improve fitness through other mechanisms in female with ovaries, not through the activation of skeletal muscle PPAR$\alpha$.
