Purpose: This study examined the effect of Kettle bell swing exercise on the body composition and lower limb muscular activity. Methods: As subjects, 26 normal adults in their twenties were divided randomly into the experiment group (n=13), in which Kettle bell exercise was applied, and the control group (n=13), in which bar exercise was applied. Both groups participated in the interventions for eight weeks with three sessions per week. Each group was assessed before training and four and eight weeks into the training to determine the effects of training intervention within and between the groups. The body composition was measured with a body composition analyzer. The changes in muscle activity were measured with a surface electromyography. An independent t-test was conducted to test the significance between the groups according to the measurement points and Repeated measured ANOVA was performed to compare the groups according to the periods with the statistical significance level set to ${\alpha}=0.05$. Results: No significant changes to the main effects of time and the interactions of time according to the measurement points were observed in the Kettle bell and control groups in the body composition (p>0.05). The muscular activity of both muscles were significantly different between the Kettle bell and control groups according to the measurement points with the exception of the right lateral gastrocnemius muscle (p<0.05). Conclusion: These findings suggest that Kettle bell swing exercise can have positive effects on the development of lower limb muscles.

PURPOSE: The purpose of this study is to identify how the body composition changes after jump-roping exercise. METHODS: The subjects are 40 college students, 20 females and 20 males. The subjects were selected among college students who had not taken any drug for more than 4 weeks before the experiment started. The experiment was performed for 4 weeks, from May 23rd to June 13rd, 2012. To collect the data, the vital signs such as pulse, blood pressure, weight), and the body composition were measured before and after the experiment. The data on the body composition were analyzed by the electrical resistance analyzer. RESULT: Muscle mass was increased and body fat was decreased for both females and males after the exercise. In particular the increase of the muscle mass and the decrease of the body fat for the females were statistically significant. The result that the body fat of the females was decreased significantly more than that of males is interpreted that the body fat of females are comparatively higher than that of males. Additionally the muscle mass of the left arm and leg of the subjects were significantly increased(p<.05). Correlation analysis between general characteristics such as body composition, abdominal obesity and specific muscle areas for both men and women showed generally positive between before and after the jump-roping exercise (p<.05, p<.01). However the correlation between sleeping time and each variable showed negative. CONCLUSION: A according to the result of this study, jump-roping exercise had a very positive effect on the body composition. The study suggests that college students keep jump roping for a long period to change their body composition favorably.

This study investigated physical and physiological changes of normal young adults, who are cadets of the Air Force Academy, have kept long-term physical activities and healthy behavior. The physical and physiological indices were the blood and body composition. Data were collected at the first year period, and then 4th year period from same group of cadets. The amounts of blood components were not changed, but variation among cadets was significantly reduced in the 4th grade period. The red blood cells(RBCs) were significantly reduced and the concentration of hemoglobin(HGB) were significantly increased. The body weight was significantly decreased in the 1st grade period since the body fat was rapidly decreased after the basic military drill, and then it was recovered with building up of the skeletal muscle in the 4th grade period. Asymmetry of the arms was decreased with the increased physical activities and usage of various equipments. The muscular endurance were significantly enhanced in the 4th grade period. The long-term physical activities and healthy behaviors may keep the physical strength through enhanced blood stream and oxygen supply by reduction of the RBCs and increased HGB concentration, and fat and muscle control.

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 : To identify changes and relationships in the fat mass and obesity associated (FTO) gene polymorphism, body composition, and physical fitness from childhood to adolescence over a three-year period spanning elementary school to middle school (2015-2018) Methods : A total of 84 male student participants were divided into two groups based on FTO genotype: aa+at (group A) and tt (group T) and tracked down. Body composition, cardiovascular endurance, flexibility, muscle strength, power, and other characteristics were measured in the two groups in both 2015 and 2018, respectively, and the changes over the three-year period were analyzed and compared. Results : Increases in height and weight did not differ significantly between the two groups, but body mass index (BMI) was significantly higher in group A (p=.035). With regard to physical fitness, there was no significant difference in flexibility, but cardiovascular endurance, strength, and power were significantly higher in group T (p<.001, p=.063, and p=.040, respectively). Conclusion : Group A is more likely to become obese than group T because of their lower level of physical fitness and increased BMI relative to group T. This result supports previous studies showing that group A has a relatively low level of physical activity and a greater tendency to eat fatty foods as compared with group T. Therefore, we suggest that the FTO gene polymorphism should be identified early and that students educated on diet and physical activity to help prevent adult obesity.

The purpose of this study is provide reference data for anthropometry and body composition and also to compare body fat estimation among skinfold thickness, BIA and NIR methods. Anthropometric measurements of height, weight, eight sites of skinfolds and six sites of circumferences were taken from 76 elderly male and 153 elderly female. Skinfold thicknesses, body composition and circumferences except waist were lowered with advancing age in elderly females and males. The degree of change with age vaired among parameters but was consistently and significantly(p<0.05) greater in elderly females than I males. Although sum of skinfold thicknesses and the amount of central and peripheral fat were significantly higher in females than that of males, the ratio of central fat to peripheral fat was significantly greater in males than in females. WHR is also significantly higher in males than that of females. This indicates that fat distribution of males tend to be centralized toward the trunk of the body than females. Estimation of body fat from skinfold thickness(male : 18.5$\pm$4.1$\%$, female : 29.7$\pm$4.0$\%$) and BIA(male : 19.5$\pm$7.3$\%$, female : 29.6$\pm$6.7$\%$) were similar but were significantly different from NIR method(male : 24.7$\pm$5.6$\%$, 34.8$\pm$4.9$\%$). Estimation of body fat by NIR measurement seemed to be more overestimated. Understanding the normal changes in body composition with increasing old age, and the ability to measure these changes and compare them with appropriate reference data are important for the health of the elderly.
