The purpose of the present study was to determine the preventive effects of combined interventional trial of fish oil treatment and exercise training on insulin resistance of skeletal muscle in high-fat fed rats. Male Wistar rats were randomly divided into chow diet (CD), high-fat diet (HF), high-fat diet with fish oil (FO), high-fat diet with exercise training (EX), and FO+EX groups. The rats in control group were fed chow diet containing, as percents of calories, 58.9% carbohydrate, 12.4% fat, and 28.7% protein. High-fat diet provided 32% energy as lard, 18% as corn oil, 27% as carbohydrate and 23% as casein. The fish oil diet had the same composition as the high fat diet except that 100 g menhaden oil was substituted for corn oil. Insulin sensitivity was assessed by in vitro glucose transport in the soleus muscle after diet treatment and treadmill running for 4 weeks. While the FO or EX only partially prevented insulin resistance on glucose transport and visceral obesity induced by high-fat diet, these interventions completely corrected hyperinsulinemia and hyperglycemia from the high-fat diet. The rats in the FO+EX showed normalized insulin action on glucose transport, plasma chemicals and visceral fat mass. Insulin-mediated glucose transport was negatively associated with total visceral fat mass (r=－0.734; p＜0.000), plasma triglyceride (r=－0.403; p＜0.05) and lepin (r=－0.583; p＜0.001) concentrations with significance. Multiple stepwise regression analysis showed that only total visceral fat mass was independently associated with insulin-mediated glucose transport (r=－0.668; p＜0.000). In conclusion, combined interventional trial of FO+EX recovered insulin resistance on glucose transport of skeletal muscle induced by high-fat diet. Visceral fat mass might be more important factor than plasma TG and leptin to induce insulin resistance on glucose transport of skeletal muscle in high-fat fed rats.

Intellectual disability affects all spheres of the lives of people can be who suffer from it. Unfortunately, modern medicine cannot cure intellectual disability. However, the quality of life improved by means of physical exercise. In this study, we compared the health-related physical fitness, metabolic syndrome index and mental health between a game biking group(5 participants) and a brisk walking group(4 participants). This study used a between-subject design and verified by non-parametric test. The participants performed an exercise program with warm up and resistance training for 12 weeks. A game bike was used for the physically impaired, where the individual looked at a screen and pedaled. The fasters he pedaled the faster the object on the screen movies. We measured health-related physical fitness, metabolic syndrome index and mental health. We also measured their perceived exertion and interest during the exercise by a visual analog scale. The results before and after the exercise program showed that health-related physical fitness, metabolic risk factors, mental health level were improved in both groups. As we hypothesized before the study, the game biking group showed a statistically significantly different level on the Rating of Perceived Exertion than the brisk walking group and a higher level on the Rating of Exercise Interest during the exercise program. Our results lead to a conclusion that an exercise program with the use of a game bike improve motivation for exercise participation in intellectually handicapped participants.

The purpose of this study was to investigate the effect of combined exercise on lung function, blood vitamin D, calcium and bone metabolism hormones in elderly women who are over 65 years by dividing them into a combined exercise group(n=13), control group(n=17). The combined exercise program included 60-minutes sessions 3times each week. Aerobic exercise intensity was 40-50%HRR(RPE 12-13) for 1-4 week, 50-60%HRR(RPE 13-14) for 5-8 week, and 60-70%HRR(RPE 14-15) for 9-12 week and resistance exercise intensity was set at OMNI-RES 3-4 for 1-4 week, OMNI-RES 5-6 for 5-8 week, OMNI-RES 7-8 for 9-12 week. As a result, lung function indicated that FEV₁ showed an interaction effect between group and time and FVC/FEV₁ levels significantly increased in combined exercise group. Blood vitamin D showed an interaction effect between group and time, also, significantly increased in combined exercise group and control group. Calcium showed an interaction effect between group and time, and significantly decreased in control group. Bone metabolism hormones indicated that both calcitonin and osteocalcin showed an interaction effect between group and time, osteocalcin significantly decreased in control group. For the following this conclusion, elderly women can be improved their lung function through 12 weeks combined exercise and also mitigate the blood vitamin D but there was no meaningful results of calcium and bone metabolism hormones.

Irisin is a myokine caused by exercise that improves insulin resistance and weight loss. However, under unfavorable conditions such as air pollution, and during the pandemic, outdoor activities are uncomfortable. Therefore, in this study, the effect of heat therapy (half bath 42 ± 0.5℃ for 30 min) on irisin circulation levels as an exercise alternative for middle-aged obese women after menopause was investigated. Subjects were 33 women aged 49.54 ± 6.04 years, with parameters of height, 160.12 ± 4.33 cm, weight, 69.71 ± 7.52 kg, body surface area 1.73 ± 0.13 m², body mass index, 27.19 ± 3.40 kg/m². The results suggest that circulating irisin levels showed a significant increase after one-time thermotherapy (TH-1). However, the increase in circulating irisin levels after 15 treatments (TH-15, 5 days/week, 3 weeks) was significantly varied. The level of adiponectin, which increases fatty oxidation to reduce fatty deposition, increased significantly at TH-1, but further increased at TH-15, which was significantly different from the level of TH-1. In addition, the basic serum free fatty acid (FFA) level was significantly increased at TH-15 compared to TH-1. Significant differences were also found in the lipid profile (body mass index, waist circumference, and % body fat). Thermotherapy can significantly increase the tympanic temperature and induce changes in circulating irisin and adiponectin levels. Thus, it resulted in positive changes in FFA and lipid profiles. Therefore, repeated thermotherapy is effective in increasing circulating irisin levels in postmenopausal obese women.

The present study aimed the effects of power resistance training(PRT) on fitness, muscle mass and short physical performance battery(SPPB) elderly women. Thirty older woman(aged 70 over years) were divided in two groups : PRT(n=15) and traditional resistance training(TRT)(n=15). The volunteers trained three times a week, during 12weeks. Both groups performed an equal work output with load red color thera-band. Three sets of twelve repetitions of each exercise were performed with rest intervals of 60s between sets. According to the results. Main fitness were significantly difference in grip strength(TRT) and cardiopulmonary. Muscle was not significantly difference. And Timed up and go and 400m walking(TRT) were significantly difference. There is sufficient effects on between training method in fitness, SPPB but PRT training may yield better results compared with TRT.

The purpose of this study was to investigate the change of body composition, biochemical index level, resting metabolic rate and daily activities by the public health center's health-promoted program in overweight middle aged women. The workout program of 12 subjects constituted by exercise(aerobic exercise & resistance training) and nutritional education for 10 weeks. As the results, there was a significant decrease in all the weight(59.0$\pm$8.9 vs 57.2$\pm$8.3kg, p<0.05), body fat percentage(33.4$\pm$4.3 vs 30.5$\pm$4.5%, p<0.05) and body fat mass(19.8$\pm$5.4 vs 17.7$\pm$4.9kg, p<0.05) after program. Fat free mass and RMR which tend to be higher after than before program were found not to be significantly. In addition, the serum HDL-cholesterol(54.3$\pm$8.1 vs 59.7$\pm$13.9mg/dl, p<0.05) and TG level(65.2$\pm$418 vs 89.4$\pm$65.6mg/dl, p<0.05) of the subjects increased at the end of the study significantly and significant correlation found between total-cholesterol and TG before program. When the other laboratory parameter were compared before and after program, hematocrit(35.1$\pm$3.3 vs 39.7$\pm$3.3%, p<0.001), platelet(225.9$\pm$49.6 vs 244.3$\pm$49.7cell/ul, p<0.05) and fasting glucose(88.0$\pm$6.5 vs 76.6$\pm$9.7mg/dl, p<0.001) increased significantly but hemoglobin(13.3$\pm$1.3 vs 12.9$\pm$1.3mg/dl, p<0.01) decreased. And in activities analysis, 'moderate activity(18.8 vs 5.8minutes, p<0.05)' clearly showed a significant decrease but 'severe activity(17.7 vs 11.4minutes, p<0.05)' showed a increase. These results suggest that continuous health-promoted program involved exercise and nutritional education at the public health center are effective to reduce body fat and to improve resting metabolic rate(RMR). Further research is required to develop more effective public health program for the middle aged women in community.

This study was conducted to investigate the effects of a participatory rehabilitation program on sit-rise and rise-to-walk test performances, and perception and motor skills in adults with medically vulnerable individuals and, adults with developmental disabilities in particular. Seventeen adults with developmental disabilities participated in a participatory rehabilitation program using resistance bands and exercise balls, for 60 minutes once weekly over 13 weeks. Their performances were measured before and immediately after the intervention, and 12 weeks after. The findings were as follows. In the sit-rise test, the number of times rising from sitting posture increased after the intervention versus before, but the difference was not statistically significant. In the rise-to-walk test, the performance showed statistically significant difference over time, and the post-hoc test showed a significant effect after the intervention versus before. There was no significant difference in perception and motor skills. In sum, the participatory rehabilitation program positively influenced dynamic balancing related to functional activities but had no significant effect on perception and motor skills, which is related to motor control and motor learning. It is suggested that to increase the participation in community activities, reduce fall risk, and improve dynamic balancing abilities in adults with developmental disabilities, participatory rehabilitation programs should be utilized to promote the physical wellbeing.
