Purpose: The purpose of this study was to examine the effects of a group walking exercise program on body composition, blood lipids and psychological factors at a community. Method: The subjects were 200 women(29 groups) who agreed to participate in group walking exercise for three months. Their ages ranged between 30 to 77 years. A simple walking exercise protocol was given to the participants, which was to do walking over three times a week and over thirty minutes each time. We compared the participants' body composition (BMI, PBF, BFM, FFM, WHR and VFA), blood lipids (HDL C, LDL C, total cholesterol, triglyceride) and exercise-self efficacy, self esteem, and quality of life before and after group walking. Collected data were analyzed through paired t test using the SAS program. Results: BMI. PBF, BFM, WHR, and VFA were significantly reduced (p<.01). However. FFM did not increase significantly (p=.416). There were significant changes in TC and TG (p<.01) but not in LDL C (P=.340). HDL C decreased but within the normal range. Exercise-self efficacy and quality of life did not increase significantly. Only self esteem increased significantly (p<.0001). Conclusion: Group walking exercise had positive effects on body composition, blood lipid and self esteem in community women.

Objectives: The objective of this study was to identify the factors associated with the percentage of body fat and bone mineral density (BMD). Methods: 886 students of the 4, 5, 6th grade were sampled from 6 elementary schools in Daejeon city from May to June 2005. Participants completed the questionnaire on socio-demographic factors, eating habits and physical activities, and had the measurements of body composition, BMD, height and weight. T-test, one-way ANOVA and ANCOVA were used to compare body composition and BMD among groups defined by study factors. Multiple regression analysis was used to determine the factors related with percentage of fat and BMD in each sex. Results: When adjusting age, height, weight and family income, the amount of food intake and regular exercise including the days of exercise per week and the daily exercise duration were significantly associated with percentage of fat in boys, but not in girls. When adjusting the same variables, regular exercise, the days of exercise per week and the daily exercise duration were positively associated with BMD in both sexes. Conclusion: Regular exercise with one or more days per week were the common factor to decrease percentage of fat and increase BMD in school children. This showed that regular exercise program could improve the body composition of school children.

Purpose: This study was done to investigate the relationship among the life style, body composition, and BMD in female college students. Method: For this study, 320 female college students aged 18 through 35 were sampled. Data were collected from June to September, 2007. The BMD was measured with Dual Energy X-ray Absorptiometry, body composition with the Body Composition Analyzer, and stature was also taken. Results: Our findings indicated that the relationship among the life style, body composition and BMD significantly varied and that meal times (F=3.318, p= .038) and muscle mass (r= .240, p< .001) and fat-free mass (r= .233, p< .001) showed a significant positive relationship with BMD. Conclusions: Our findings indicated that optimal levels of the fat-free mass and muscle mass should be maintained. Since a decrease in the quantity of bones is expected to cause health issues for women after menopause, it is necessary to reduce risk factors including the unhealthy life style of college women that may lead to osteoporosis, and to introduce preventive nursing interventions against osteoporosis.

Purpose: The purpose of this study was to examine the effects of a 12 week walking program on the risk factors associated with metabolic syndrome in older people in rural areas. Method: A total of 31 people among the people who live within the area served by E County Community Health Practice were observed from December 5, 2006 to February 23, 2007. This group included 18 people who were identified as having metabolic syndrome on the basis of the Asia-Pacific fatness basic standard (the experimental group) and a control group of 13 people who did not have metabolic syndrome. Results: The results of the study are as follows: In the experimental group, there was no significant difference in body composition between pre and post measurement. The small change in values that were observed in the experimental group did not reach statistical significance. However, body composition values in the control group increased. In the experimental group, there were significant differences in waist circumference, blood pressure, HDL-C, and fasting blood sugar between pre and post measurement. But there were no changes in the control group. There was no difference in TG in either group. As to changes in risk-factors related metabolic syndrome after the 12 week walking program, the number of risk-factors were effectively reduced in the experimental group, but not in the control group. Conclusion: According to the present study, a 12 week walking program led to significant improvement in body weight, BMI as the factors composing the body and in waist circumference, HDL-C, blood pressure, and fasting blood sugar as risk-factors related to metabolic syndrome in older people in rural areas.

Object : Waist circumference(WC), waist-hip ratio(WHR), waist-stature ratio(WSR), and body mass index(BMI) are commonly used for evaluating obesity. This Research were done to determine what is more sensitive obesity indexes(WC, WHR, WSR, BMI) Correlated with body composition such as body fat mass, body fat(%), visceral fat area, and fat free mass. And what is more sensitively correlated obesity indexes with % changes of body composition during weight reduction treatment. Methods : This clinical retrospective research were carried out 127 cases of female obese outpatients with weight reduction treatment during 1 month. Bioelectrical impedence analysis(for body composition) and body size(for anthropometric obesity indexes) were estimated in pre-treatment and post-treatment to evaluate the obesity indexes. Pearson correlation coefficients were used to select useful obesity index. Result & Conclusion : BMI is useful index for diagnosis and evaluation of obesity. WSR is sensitively correlated with visceral fat area and body fat(%). So, WSR is useful index for evaluating abdominal obesity and risk factors of metabolic syndrome. WC is correlated with both body fat mass and fat free mass. WHR is not optimal for diagnosis and evaluation of obesity.

Purpose: The purpose of this study was to identify the levels of bone mineral density (BMD) and to explain the factors influencing BMD among female college students in Korea. Methods: A cross-sectional study was conducted with 144 college women. Lifestyle factors were determined by self-report questionnaire. Body composition was measured by body composition analyzer and bone mineral density was measured by ultrasound bone densitometry. Data were analyzed using SPSS for windows, version 19.0. Results: The mean BMD at calcaneus site was 0.56$g/cm^2$ (mean T-score=-0.22). The incidence of osteopenia was 21.5%. Factors predicting BMD were menarche age (r=-.22, p=.009) and height (r=-.18, p=.030) with 7% of explained variance. Conclusion: These results suggest that health care professionals need to provide young women with program that is intended to affect their intention toward osteoporosis preventive behavior change.

Purpose: This study was to investigate the effect of a 12-week plyometric training on body composition, physical fitness and bone mineral density in obese male adolescents. Method: Twenty adolescent boys who are obese were randomly assigned to a control group (CON, n=10) or plyometic exercise group (EXE, n=10). The EXE group was performed 3 times per week for 12 weeks. The body composition, physical fitness, and bone mineral density were measured before and after the 12 weeks intervention. Results: The results of this study were as follows: i) In EXE group, the fat mass was significantly decreased between pre and post, whereas the difference of the body weight, BMI, and LBM were not significant. ii) Among the physical fitness factors, grip strength, muscular endurance, and 2 0m shuttle running were significantly improved but flexibility did not show any significant difference. iii) The bone mineral density was significantly improved between pre and post in EXE group. Conclusion: These results suggested that plyometric training for 12 weeks may be effective in improving body composition, physical fitness, and bone mineral density in obese adolescents. Further implications were discussed.
