The purpose of this study is to investigate the effect of the jumping diet program, which is popular in GX exercise, on lifestyle - related factors and blood stress in obese middle - aged women. Subjects underwent a 40-minute-a-day exercise three times a week for eight weeks and to determine the difference between before and after exercise, a t-test of the corresponding sample was conducted and the following conclusions were drawn. The results of decreasing body weight and body fat percentage after exercise were found to be statistically significant. In addition, it was decreased in TC, LDL-C and TG, which are lifestyle-related factors, and HDL-C was increased, resulting in statistically significant results, and the fasting blood glucose level was maintained to be normal. And blood stress did not enter the normal range, but decreased, indicating a significant difference. Taken together, the jumping diet exercise program improves body composition items and lifestyle-related factors in obese middle-aged women and reduces blood stress. Although the duration of jumping exercise was relatively short, it was thought that improvement of body shape and lifestyle - related factors were obtained for middle - aged obese women through 30 minutes of high intensity exercise and muscle power supplementation exercise. If I continue this exercise for a long time, I think it is one of the exercise programs that can relieve middle age obesity and maintain health.

The purpose of this study is to investigate the effects of isokinetic exercise program on lumbar muscle strength and chronic low back pain in 3040 women with low back pain. The subjects were randomly sampled 20 female 3040 women living in S city and divided into 10 exercise groups and 10 control groups, and performed isokinetic exercise for 8 weeks. After exercise, the differences in the groups were subjected to paired t-tests, and differences between groups were subjected to independent t-tests. The following conclusions were obtained. First, it showed that 30o/sec peak torque flexion, the 30o/sec peak torque extension/body weight, and the 30o/sec peak torque flexion/body weight was a statistically significant difference after isokinetic exercise in the exercise group (p<.001). Second, 30o/sec Agonist/Antagonist Ratio showed statistically significant difference after isokinetic exercise in the exercise group (p<.05). Third, Visual Analog Scale (VAS) and Verbal Rating Scale (VRS) showed statistically significant difference after isokinetic exercise in the exercise group(p<.001). Fourth, the results of the pre-specimen between the two groups showed a statistically significant difference at 30o/sec peak torque flexion, 30o/sec peak torque flexion/body weight, and 30o/sec agonist/antagonist ratio. The results of the post-specimen between the two groups showed statistically significant differences at 30o/sec peak torque extension, 30o/sec peak torque extension/body weight, visual analogue scale (VAS) and verbal rating scale (VRS)(p<.05). When sum up the above results, if we perform isokinetic exercise periodically, 3040 women suffering from chronic back pain will be able to relieve their pain by strengthening their back strength. In addition, chronic low back pain has been expanding to all ages in recent years. Therefore, future studies are expected to reduce the pain and reduce the medical expenses by applying isokinetic exercise program to adolescents and the elderly.

The purpose of this study is to examine the perception of sports international exchanges among college students in Korea and Japan and to compare their perceptions of sports exchanges between the two countries. The subjects were physical education students(n=108) who attended C university in G city, Korea and students(n=100) attending K - area K university in Japan. In order to see the differences in the perception of sports exchanges between the two countries, the independent sample t test method was conducted. Based on the results, the following conclusions were obtained. In terms of the effect of participating in international exchange, Japanese students showed the importance in skill improvement, motivation, joy, confidence, ability improvement, interest, and interpersonal factors and Korean students showed importance in international sense, knowledge information and friendliness factor. As a result of the need for international exchange, Japanese physical education students showed a more significant difference in perception, language learning, relationship conscious effort, energy passion, and readiness. As a result of the abovementioned results, we conducted a survey on the sports interaction among students from Korea and Japan. As a result, it was found that Japanese students were more likely to participate in international exchanges They are aware of their interest and importance. The results of this study show that there is no big gap between the two countries. However, as suggested by the general characteristics, the recognition of the necessity of foreign travel experience and the hoped effect are the result of the basic and direct differences of experiences and cognitions about sports exchanges among students of Japanese physical education major compared with those of Korean physical education major. Students who major in physical education will be able to demonstrate their ability to develop sports in their respective countries as sports professionals who are awake to internationalization if they are more aware of sports exchanges and approach with more positive thoughts.

This study was conducted to investigate the effects of trampoline exercise on blood oxidative stress and total antioxidant activity in middle-aged women. Middle-aged women consisted of 40 minutes a day, three times a week for a total of eight weeks, divided into exercise group and general control group. The following conclusions were drawn. First, it was found that there was an interaction effect only in measurement time * groups in blood oxidative stress of middle-aged women participating in trampoline exercise. Second, the total antioxidant power of middle-aged women who participated in the trampoline exercise also showed an interaction effect between the measurement time * groups. Taken together, the trampoline exercise is recommended as one of the exercise programs to help middle-aged women maintain their health by reducing the blood oxidative stress and increasing the total antioxidant power of middle-aged women. In order to get more exercise effect, extend the exercise period and increase the intensity, than I think it will be possible to have a healthy middle age by promoting health.

In this study, we classified middle-aged women with borderline obesity into the exercise group(n=20) and a total of 8 weeks of combined(band+circulation) exercise program was performed. The results were compared with those of 0 week and 8 week. First, blood pressure of middle-aged women with borderline obesity increased in the second measurement rather than the first measurement, and maintained the normal level. Second, there was no statistically significant difference in the waist circumference, body weight, and body fat percentage in the health-related physical fitness of the borderline obese middle-aged women. There was also a statistically significant difference in muscle strength, muscle endurance, cardiovascular endurance, and flexibility. In conclusion, we conclude that combined exercise for middle-aged women with borderline obesity is one of the exercise programs that can improve the physical fitness level with positive blood pressure maintenance and improvement of health-related physical fitness. In later studies, exercise intensity and frequency were found to be better for women with borderline obesity, and it would be expected to prevent diseases such as lifestyle-related diseases.

In this study, we used the Elastic Band exercise as a method to prevent obesity and various diseases of middle-aged women who had little physical activity and compared the body composition, liver and blood glucose levels. The following conclusions were obtained. There was a decrease in body weight but no statistically significant difference. Body fat percentage was also decreased, showing statistically significant difference. There was a statistically significant difference the AST and the ALT. However, γ-GTP was significantly decreased but not statistically significant. The blood glucose level was in the normal range but decreased, indicating a statistically significant difference. From the above, it is suggested that Elastic Band exercise is recommended for middle-aged women because it has significant changes in body composition, liver and blood sugar. I would like to study the effect of the Elastic Band movement by studying and analyzing the movements using the elastic band.
