The purpose of this study was to investigate The effect of weight training method on body composition and bone mineral density of college female in twenties. Subjects of 14 college female students divided in two group/weight training group of 7 female students and circuit weight training of 7 female students) in this study. All subjects performed body composition, skinfold thickness, and bone density before and after a 8-week training.

비만중년여성들의 복합운동프로그램이 신체구성 및 아디포넥틴과 C-반응성 단백에 미치는 영향

나승희(Seung Hee Na) 한국사회체육학회 2007 한국사회체육학회지 Vol.0 No.31

The present study applied a 12 weeks` composite exercise program to 21 obese middle-aged women whose body fat percentage was over 30%, classifying the subjects at random into a control group (n=7), exercise group I (n=7) and exercise group II (n=7), and observed how the exercise program affected adiponection, which is a obesity-related hormone, and C reactive protein, which is an index of cardiovascular diseases. Data obtained from this experiment were analyzed using SPSS/ PC+ Version 12.0 and means and standard deviations were calculated. In addition, difference between before the application of the exercise program and 12 weeks after the exercise was tested through paired t-test. Conclusions drawn from this study are as follows. After the 12 weeks` composite exercise program for middle-age obese women, the control group showed an increase in weight, body fat, and lean body mass, and no change in fat-free mass while the exercise group (I) and the exercise group (II) showed a significant decrease (p<.01) in weight, body fat, and lean body mass with the increase of fat-free mass, which however failed to bring any statistic significance. In adiponectin, the control group showed an increase but it didn`t show any statistic significance while the exercise group (I) and the exercise group (II) showed statistically a significant increase (p<.o5). In CRP, the control group showed a decrease with no statistic significance while the exercise group (I) and the exercise group (II) showed statistically a significant decrease (p<.o5).

Second, regarding %fat, a significant decrease was found only in the combined exercise group(p<.001) and a significant difference was found among three groups at p<.001. Third, regarding bone density, a significant increase was found in the femur only in the combined exercise group(p<.001) and a significant difference was found among three groups(p<.001). A significant difference was found in the lumbar vertebra in the combined exercise group(p<.001) and the exercise group(p<.01) and a significant difference was found among three groups(p<.001). Finally, a significant decrease was found in TC in the combined exercise group and the exercise group and a significant difference was found among three groups(p<.01).

This study applies online lecture service quality factors to IPA analysis, analyzes importance and satisfaction, and prepares and analyzes the epidemic corona era through classification of maintenance items, concentration items, low priority items and excess items to demonstrate. Provide the data. I have a research purpose to do it. In this study, a population was set for students who participated in university online classes by reinforcing social distancing in the corona-19 outbreak, and a questionnaire was conducted centering on college students in the G area from January to February 2021 using a convenient sampling method. I did. A total of 220 copies were used for the final study. Among the sub-factors of the importance of online lecture service quality, learning accessibility (M=4.41) was the highest, and learning convenience (M=4.31), administrative services (M=4.29), teaching methods (M=4.27), and learning usefulness (M=4.09). As for the sub-factors of online lecture service quality satisfaction, learning accessibility (M=4.13) was the highest, teaching method (M=4.10), learning usefulness (M=4.03), administrative service (M=3.96), and learning convenience (M=3.95). First, there is currently an important and satisfactory strength, but it must be maintained and supplemented for continuous competitiveness. Second, a plan to increase the acceptance rate, such as familiarity with the viewing manual, database server, and update, should be sought, and academic management should be planned in accordance with the technical limitations of online. Third, it should not be neglected regardless of the results of the professor"s professionalism and basic knowledge, provision of information related to the course, and monitoring of information services. Fourth, since it is an item related to the learning preparation of the professor, which is the basis of education, constant attention and effort to gain comparative advantage on the school side are required.

댄스스포츠가 복부비만 여성의 Ghrelin과 Leptin 및 혈중지질에 미치는 영향

나승희 ( Seung Hee Na ) 한국스포츠리서치 2007 한국 스포츠 리서치 Vol.18 No.4

The present study divided 24 women with abdominal obesity (the ratio of visceral fat to abdominal subcutaneous fat over 0.4) into a dance sports group (n=12) and a control group (n=12), executed a dance program (7 motions based on the basic steps of cha-cha-cha, one of Latin dances), and examined the effects of the program on ghrelin, leptin and blood lipid. From this study were drawn conclusions as follows. After 12 weeks` dance sports exercise, the levels of TC, TG and LDL-C decreased significantly, and the level of HDL-C increased significantly. After 12 weeks` dance sports exercise, ghrelin increased significantly and leptin decreased significantly. However, the exercise group showed no significant change in the V/S ratio but the control group showed a significant increase. Significant differences were observed in ghrelin, leptin and the V/S ratio between the two groups. The results of this study show that dance sports are effective for abdominal obesity in middle-aged women with obesity as they decrease leptin and V/S (the ratio of visceral fat to abdominal subcutaneous fat), which are related to body fat. However, change in the level of ghrelin was different according to age, the intensity of exercise, the method of exercise and the period of program, so it requires further research.

밴드운동이 폐경기 여성의 골밀도 및 혈중지질, 기초체력에 미치는 영향

나승희(Na Seung-Hee) 한국체육과학회 2006 한국체육과학회지 Vol.15 No.1

The present study purposed to examine the effects of a band fitness program on menopausal women's bone density, blood lipid and basic physical strength. For this purpose, we measured and analyzed radius and femur for bone density, TC, TG, LDL C and HDL C for blood lipid, and muscular force, power, swiftness, flexibility and counterbalance for basic physical strength before and after the exercise for 10 weeks, and drew conclusions as follows. 1. As for bone density, increases were observed in radius and femur but they were not statistically significant. 2. As for blood lipid, no statistically significant change was observed in Te, TG and HDL wed a statistically significant change (p<.05). 3. As for basic physical strength, statistically significant changes were observed in muscular force and flexibility (p<.05) but not in power, swiftness and counterbalance. According to the results of this study, band fitness can be applied as a useful tool for preventing and treating adult diseases in menopausal women, and it is considered necessary to make further research on the detailed effects of band fitness programs with different groups of subjects and research plans.
