          단시간 고강도 다빈치바디보드 운동이 중년여성들의 만성질환에 미치는 영향

          서영환(Seo, Young-Hwan) 한국체육과학회 2020 한국체육과학회지 Vol.29 No.2

          Recently, as women enter middle age and old age, they are exposed to various diseases that worsen their health. In middle-aged women, physical activity is rapidly reduced due to family and social life, which is hampering health. Therefore, the purpose of this study was to investigate the effects of short-term high-intensity exercise on da Vinci bodyboard exercise for middle-aged women who had insufficient time to affect various chronic diseases (liver level, kidney function). The 12 middle-aged women who did not experience the da Vinci bodyboard exercise were selected. In the change of liver level, AST and ALT decreased after the da Vinci bodyboard exercise, which was statistically significant. In the changes in kidney function, Creatine decreased after the da Vinci bodyboard exercise, which was statistically significant. Urea decreased after the da Vinci bodyboard exercise but did not show statistically significant levels. Taken together, the Da Vinci Bodyboard exercise is thought to improve liver and kidney function in middle-aged women who lack physical activity. As such, if middle-aged women who are in short of time and continue to exercise to improve their health by short-term high-intensity exercise, it is thought that they will be able to live a healthy life by preventing various chronic diseases coming in middle and old age.

          Most research on feedback has focused on its informational role. In contrast, motor learning researchers have somewhat neglected the motivational aspects of feedback, perhaps because motivation is often assumed to exert only temporary effects on performance or to have, at best, indirect effects on learning through increased practice. But more recently, studies following up on findings indicating that learners preferred to receive feedback after good trials have shown that providing feedback after relatively successful trials can enhance motor learning relative to feedback after less successful trials. This study examined motivational effects of feedback on motor learning. Specifically, we investigated the influence of social-comparative feedback on the motor learning of a badminton short serve task. Twenty-eight university students with mean age of 19 years took part in this experiment. Participants were randomly assigned to the positive feedback and control groups, with an equal number of females in each group. The practice data were analyzed in 2(groups)×6(blocks of 10 trials) analyses of variance (ANOVAs) with repeated measures on the last factor. The retention and transfer data were analyzed in seperate one-way ANOVAs. Bothe groups reduced their absolute and variable errors across the practice phase. The main effect of block was significant p<.001. And on the transfer test, requiring novel absolute short serve, the social-comparative group had smaller errors than the control group(p<.05). The findings of the present study demonstrated evidence that motivational factors have transient effects on motor performance and affect motor learning.

          점핑 다이어트 프로그램이 비만중년여성들의 생활습관병 관련인자와 혈중스트레스 요인에 미치는 영향

          서영환(Young-Hwan Seo), 오장록(Jang-Rok Oh) 한국발육발달학회 2019 한국발육발달학회지 Vol.27 No.3

          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.

          규칙적인 복합운동이 경계성 비만 중년여성들의 혈압과 건강관련체력에 미치는 영향

          서영환(Seo, Young-Hwan) 한국체육과학회 2019 한국체육과학회지 Vol.28 No.3

          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.

          걷기운동프로그램이 비만중년 여성의 혈장 고감도 C-반응성 단백(hs-CRP), Interlukin-6 및 TNF-α에 미치는 영향

          서영환(Young Hwan Seo), 강선영(Sun Young Kang), 강형숙(Hyoung Sook Kang), 김영표(Young Pyo Kim), 윤진환(Jin Hwan Yoon) 한국사회체육학회 2009 한국사회체육학회지 Vol.0 No.37

          The purpose of this study was to investigate the effect of walking program on plasma hs-CRP, interlukin-6 and TNF-α in obese middle-aged women. The subjects for this study were composed of twenty-three obese middle-aged women. The subjects were classified to two groups; control group(CG, n=13), walking exercise group(WEG, n=15). The WEG exercised for 12 weeks and were monitored for changes in BMI(body mass index), C-reactive protein(CRP), interlukin-6(IL-6), and tumor necrosis factor-alpha(TNF-α). The results of this study are as follow; BMI was significantly decreased in WEG after 12 weeks of walking exercise. CRP, IL-6, and TNF-α were significantly decreased in WEG after 12 weeks of walking exercise. CRP, IL-6, and TNF-α showed a significant correlation with BMI. In conclusion, the results of this study suggest that walking exercise can contribute to the better benefit in BMI, CRP, IL-6, and TNF-α for obese treatment.

          한·일 체육전공 학생들의 스포츠 교류인식에 대한 조사 연구

          서영환(Young-Hwan Seo), 鄭英美(Young-Mi Jung) 한국발육발달학회 2018 한국발육발달학회지 Vol.26 No.3

          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.

          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.

          탄력밴드를 이용한 저항운동이 중년여성들의 간기능과 혈중 Glucose에 미치는 효과

          서영환(Seo, Young-Hwan) 한국체육과학회 2019 한국체육과학회지 Vol.28 No.1

          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.
