Due to aging, the physical fitness of middle-aged women decreases after menopause. This results in increased body fat and reduced lean body mass, both of which can lead to obesity. This phenomenon is accompanied by changes in hormone secretion in the body. The purpose of this study was to analyze the effects of circuit training on aging-related hormones in obese middle-aged women. The subjects were 20 obese middle-aged women. The subjects were divided into two groups: a circuit training group (n=10) and nonexercise control group (n=10). Growth hormone (GH), insulin-like growth factor-1 (IGF-1), estrogen, and DHEA-S were measured before and after the circuit training program. The circuit training group performed circuit training for 12 weeks, three times per week. Exercise intensity was increased gradually from 60% to 80% of heart rate reserve every 6 weeks. In the circuit training group, at the end of the 12-week training program, the IGF-1 levels were significantly increased compared to pre-exercise levels, and they were higher than those of the control group. GH levels were also significantly increased in the circuit training group, but the differences were not statistically significant. DHEA-S was significantly increased in the circuit training group, but the difference was not statistically significant. The results showed that circuit training improved aging-related hormones levels in obese middle-aged women.

As divorce and singlehood have been on the rise over the last decades, marital statuses are more diverse than the past for middle-aged men and women in South Korea. While marital status is crucial for health behaviors and statuses, but few studies examine the associations between health differentials and marital status for the middle-aged in South Korea. Using the 2010 Social Survey collected by the Statistics Korea, this study analyzes how health behaviors and statuses vary by the marital status. In particular, this paper examines whether marital statuses and gender interact to influence health behaviors and statuses. I find that married middle-aged people are healthier than divorced, single, and widowed middle-aged people. But this the negative influence of the non-married status are much greater for men than women. Some female non-married groups do not differ from married middle-aged people in some indicators of health behaviors. Single female middle-aged people are better in general satisfaction levels than married middle-aged people.

This study was built to figure out the changes in Cortisol, Free fatty acids and muscle damage indicators, by conducting eight-week interval Taekwondo programs to obese women in their middle age. The exercise programs was consisted of 40 minutes interval Taekwondo workout each time, using the movement of the 80-85% of HRmax intensity. Overall, we got the following conclusions as a result of the conduct. First, Cortisol decreased before and after the 8 week interval, but it did not show a significant change. Second, the FFA showed a significant change by decreasing before and after the 8 week interval. Third, the muscular damage indicators showed a small decrease before and after the Taekwondo workout, but didn't show a significant change. Ultimately, the interval Taekwondo program didn't have a significant effect on improving stress tolerance, stress resistance and protecting muscle injuries, but can be effectively used to increase the lipid oxidation ability.

This study randomly assigned 24 middle-aged women to determine the effect of a 12-week combined exercise program on cardiovascular function and electrocardiogram-based ST segment and QRS in obese middle-aged women. Analysis of the results was conducted to verify differences within groups and between periods and groups. In terms of cardiovascular function, myocardial oxygen consumption showed a significant decrease in the experimental group during the resting phase and the highest intensity phase during exercise, and an interaction between group and period at rest was also observed. The heart rate recovery rate showed a significant decrease in the experimental group at 2 minutes of recovery, while in the control group, on the contrary, a significant increase was observed. The experimental group showed a significant decrease in systolic blood pressure, and an interaction between group and period was also observed. There was no change in diastolic blood pressure in both the experimental and control groups, and there was a statistically significant decrease in pulse pressure only in the experimental group at the 3-minute recovery stage. In the case of the electrocardiogram, the QRS height in the experimental group showed a significant increase in most cases at rest and at 3, 6, and 9 minutes during the recovery period, while there was no significant difference in the QRS period in both the experimental and control groups, and the ST segment height was significantly increased at rest in the experimental group. appeared to have increased. Therefore, summarizing the results of this study, it is believed that the 12-week combined exercise program has a positive effect in improving cardiovascular function, ventricular contractility in electrocardiograms, and myocardial ischemia in obese middle-aged women.

The purpose of this study was to investigate the effects of isometric exercise based MNIT treatment on body composition, blood lipids, leptin and CRP in middle-aged obese women. For this purpose, middle-aged obese women (age: 40-50) with more 30% of body fat percentage in U city were recruited. They were divided into MNIT group(MG, n=9) and control group(CG, n=9). MNIT group was performed hand therapy program with abdomen exercise equivalent to RPE (9-11) (week 1-4) and exercise equivalent to RPE (11-12) (Week 5-8) and exercise equivalent to RPE (12-13) (week 9-12) 60 minutes a day for 3 days a week in 12 weeks. The results of this study were as follows: Body weight, fat mass, and body mass index had a significant lower in MG group than CG. There are no significant changes in blood profiles, and leptin. In conclusion, isometric based on MNIT may lead to development of an alternative therapy for middle-aged obese women.

The purpose of this study is to analyze the effects of aerobic exercise on immune function, physical fitness and fat mass in middle-aged women. Twenty subjects were divided into two groups : experimental group(N:10) and control group(N:10). Experimental subjects were under the exercise conditions to perform the aerobic exercise using the movement of dance-sports with intensity of 60~80% HRmax for 60 min/day, 3 times/week during 12 weeks. After the aerobic exercise, the numbers of neutrophil, Iymphocyte, eosinophil, basophil, 73, 74 and B4 were significantly different. Crip-strength and sit-up ability significantly improved and all so weight and fat mass decreased on experimental group. Therefore, the aerobic exercise using the movement of dance-sports applying to middle-aged women would contribute them healthy life and prevention of chronic disease.

This study was tested growth hormone and fatigue materials after eight-week high-intensity interval exercise to middle aged women (40's~50's women) who have been obesity without other disease. Two group of 20 candidates were randomly divided 10 persons as exercise group and control group. Exercise was conducted 8 weeks 4 days 35 minutes, before the study each group was checked vital sign for fatigue materials. It showed the following results. First, it has been increased growth hormone level after exercise program compared each group, significantly. Secondly, it has been decreased fatigue materials due to the high-strength interval workout for 8 weeks compared control as significantly. As a result, eight-week high-intensity interval exercise could be increased growth hormone levels by reducing fatigue and it might be preventing fatigue materials levels. We would suggest that high-strength interval workout for 8 weeks could have a positive effect for preventing and reducing fatigue and related disease, obesity.

The purpose of this study was to investigate the effects of regular taekwondo training on neurotrophic factors and cognitive function in obese middle-aged women. Thirty-three middle-aged women with obesity were selected for this study and randomly assigned into a control group(CG, n=18) and an taekwondo group(TG, n=15). The TG performed taekwondo training 5 times weekly for 16 weeks, while the CG did not exercise training. Serum brain-derived neurotrophic factor(BDNF), vascular endothelial growth factor(VEGF), and insulin-like growth factor-1(IGF-1) levels were analyzed and Stroop Color and Word tests were performed before and after the intervention. The serum BDNF and IGF-1 levels were significantly increased in the TG after the intervention(p<.05). On the other hand, no statistically significant differences were found in the serum VEGF levels, or in the Stroop Color and Word Test scores(p>.05). These results suggest that regular taekwondo training may be affects levels of peripheral neurotrophic factors but not cognitive function in obese middle-aged women.
