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.

Correlation and similarity of garlic cultivars was analyzed by measuring the composition of twenty amino acids contents in the bulb and callus from twelve garlic cultivars which were collected from Korea and foreign countries. Arginine and asparagine occupied more than 78% of total amino acids both in bulb and callus followed by glutamic acid, lysine, aspartic acid, valine, glycine, histidine and ornithine in order. Based on correlation coefficients of amino acid composition in the bulb, twelve garlic cultivars were classified into three major groups. Danyang, Euiseong, Seosan, Jeju, Mongol and Turkey cultivars belong to group-I, Namdo, China, Mexico and Nepal cultivars are in group-II, and group-III includes Philippine and Daeseo cultivars. Based on amino acid composition in callus, group-I includes Mongol, Euiseong, Danyang and Seosan cultivars, group-II includes Jeju, Daeseo, China and Namdo cultivars, group-III includes Napal, Mexico, Philippine and Turkey cultivars. Composition of amino acid contained in both callus and bulb is a clear standard to identify northern-type garlic cultivars. Especially the composition of amino acids in callus is more distinctive standard of classification between northern and southern type garlic cultivars than that in bulbs.

Purpose : This study was conducted to determine the effects of a brain spinning program on cognitive function, body composition, health related fitness and physical self-efficacy of children and adolescents. Methods : This study, 34 children and adolescents were selected and divided into two groups : the exercise group (n=16), which received a brain spinning program and the control group (n=16), which did not receive any exercise program. The program was conducted for 30 minutes three times a week for 4 weeks, and the cognitive function, body composition, health related fitness and physical self-efficacy were measured both before and after the program. Results : The exercise group, which received a brain spinning program showed a significant increase in short-term memory (p<.05) and working memory (p<.01), and muscle mass increased significantly only in the exercise group (p<.05). In addition, left grip strength increased in the exercise group (p<.01), and the maximum oxygen intake decreased significantly only in the control group (p<.05), and Sit-forward bend increased significantly only in the exercise group (p<.01). Physical self-efficacy significantly increased only in the exercise group (p<.05). Conclusion : In summary, short-term memory, cognitive efficiency, working memory, muscle mass, left grip strength, maximum oxygen intake, and left forward bending in children and adolescents significantly increased after the 4-week brain spinning program. However, the control group that was not provided with the 4-week brain spinning program showed a significant increase in body weight and a significant decrease in maximum oxygen intake. In conclusion, the 4-week brain spinning program has positive effects on short-term memory, cognitive function, muscle mass, muscle strength, cardiorespiratory endurance, flexibility, and physical self-efficacy.

The purpose of this study is to investigate the effects of indoor and outdoor exercise environments on bone mineral density and body composition in old women. A total of 26 old women were randomly divided into two groups: an indoor exercise group (IE, n=13) and an outdoor exercise group (OE, n=13). The exercise groups performed moderate exercise (HR max 50~70%; RPE 11-15) three times a week for 60 minutes over 20 weeks. After exercise training, bone mineral density was significantly improved in the OE group as compared with the IE group. Body fat mass was significantly decreased in the IE group. Weight, lean body mass, and body fat mass were significantly decreased in the OE group. Body mass index was significantly decreased in the outdoor exercise group as compared to the IE group. Our findings show that a 20-week program of outdoor exercise training improves bone mineral density and body composition in old women. As mentioned above, it has been found that engaging in an outdoor exercise program for 20 weeks has a positive effect on bone mineral density and body composition in old women. In conclusion, engaging in the outdoor exercise program, including aerobic and resistance exercises, for 20 weeks improved bone mineral density and inhibited bone loss in old women and had a positive influence on vitamin D levels, thereby potentially lowering the risk of osteoporosis.

The present study was carried out in atheroscleorotic New Zealend white(NZW) rabbits. to evaluate the effect of dietary supplementation with Korean pinenut oil, on plasma total fatty acid composition. In study I, NZW rabbits were fed 10 weeks on a commercial chow diet supplemented with 5% of energy as fats(soybean oil or pinenut oil) or 10% of energy as fats(soybean oil or pinenut oil) with the addition of 1% cholesterol to the diet. Nineteen fatty acids ranged from myristic acid (14:0) to cervonic acid (22:6 ${\omega}3$) were identified in all the samples. The c5, c9, $c12{\sim}18$ : 3 acid was not reported in the fatty acid methyl ester profiles of each group because it was included in the linoleic acid peak. The major constitutent fatty acids in the chow diet group were linoleic acid, oleic acid, palmitic acid and ${\alpha}$-linolenic acid. In the cholesterol group, oleic acid, linoleic acid and palmitic acid were the major fatty acids. In plasma of cholesterol-fed animals, the levels of 16:1 ${\omega}$ 7 and 18:1 1 ${\omega}$ 9 were increased. Linoleic acid was the major fatty acid in soybean oil/cholesterol and pinenut oil/cholesterol groups. Plasma linoleic acid levels were significantly incresed from 4 to 6% by the supplementation of 5% soybean or 5% pinenut oil in the cholesterol diet for 5 weeks, compared to cholesterol group. Plasma 16 : 1 ${\omega}$ 7 levels in animals fed with 5 or 10% pinenut oils were significantly lower than in those fed cholesterol for 5 weeks. After 10 weeks on the soybean oil and pinenut oil diet there were no significant differences in the fatty acid composition. In study II, the fatty acid composition was not affected by the types or levels of oils supplemented for 5 weeks. After 10 weeks on the oil diets 16:1 ${\omega}$ 7 and 18:1 ${\omega}$ 9 were decreased in 10% soybean in oil/cholesterol and 10% pinenut oil/cholesterol groups, compared to cholesterol group.

Serum and liver lipid levels and fatty acid composition of liver phospolipids (PL) were investigated in 36 rats which consumed either one of five different dietary fats or a high carbohydrate diet for 4 weeks. As the sources of five dietary fats, concentrated cicosapentaenoic acid(EPA), fish oil (FO), perilla oil(PO), corn oil(CO) and beef tallow (BT) were provided to the rats. As a control group, cron starch (CS) replaced dietary fat. The FO group showed lower serum total cholesterol (TC), high density lipiprotein cholesterol(HDL-C) and serum PL levels than those of the CO group(p<0.05). There were no significant differences in serum TC and serum HDL-C levels between the polyunsatured fatty acid(PUFA) groups and the EPA, FO and PO groups. The CS group showed the highest level serum TC. Compared with the CS group, both the EPA and CO groups showed significantly lower atherogenic indices(AI). However, there were no significant differences in AI among different dietary fat groups. No significant differences in liver triglyceride (TG) , TC and PL levels were detected among the six experimental groups. Phosphatidylcholine(PC) and phosphatidylethanolamine(PE) composed 30-40% and 15-20% of total liver PL, respectively. The fatty acid composition of liver PC and PE reflected dietary fatty acid composition . Compared to the different dietary fat based diets used in our study, the high carbohydrate diet had the most adverse effects on serum lipid profiles. However, we can not conclude from this result that long chain n-3 PUFA diets such as the EPA and FO based diets have more beneficial effects on serum lipid profiles than n-6 PUFA diet such as the CO based diet or shorter chain n-3 PUFA diets like the PO based diet.

This study was carried out to investigate distribution of obesity, body composition, weight control and dietary behaviors, and to analyze the relationship between Body Mass Index (BMI) and physical characteristics, body composition and dietary behaviors by anthropmetric measurement and questionnaires. The 199 study subjects were divided into 3 age groups; 30's (78), 40's (77) and 50's (44) and 4 groups by BMI ; under weight (4.5%), normal (51.3%), over weight (26.1%) and obese (18.1%). Amount of skeletal muscle, body water, mineral and body fat were significantly increased with BMI. There were especially significant increase skeletal muscle 5.3 kg ($19.1\;{\rightarrow}\;23.5\;kg$), body water 5.3 kg ($26.3\;{\rightarrow}\;31.6\;kg$) and fat 15.2 kg ($11.2\;{\rightarrow}\;26.4\;kg$) from under weight to obesity group, respectively (p < 0.01). There were significantly decreased in the ratio of body water (10.3%), protein (2.7%) and body mineral (1.1%) from under weight to obesity, but significant increase 14.1% in body fat (p < 0.001). About 44.4% of under weight group and 40.1% of normal group and 50% of over and obesity group had dissatisfaction on their body images. Most of the women were concerned about their body images and experienced weight control. Dietary behavior scores of obesity group were significant lower than the other four groups (p < 0.001). There were significant positive correlation between BMI and body water (r = 0.62), protein (r = 0.52), skeletal muscle (r = 0.63), body fat (r = 0.91) and WH ratio (r = 0.91), respectively (p < 0.001). The correlation between BMI and body fat and WH ratio were much higher than the correlation between weight and fat and WH ratio.

Antler has been used as one of the important traditional oriental medicines for many years. It contains many biochemical components including lipids, peptides, carbohydrates, and inorganic substances. The various biological activities of antler are being considered owing to such biochemical components. The purpose of this research is to compare the biochemical components of antlers after treatment of three different kinds of fodder. They are mulberry (group A), Lycii Fructus (group B) and the complex of herbs (group C). The chemical composition of each antler was determined in three sections (top, middle, and bottom) and compared with those of the control. The contents of sialic acid, uronic acid and glycosaminoglycans increased in the top antlers of the group B. Total lipids content increased in the top antlers of all groups (A, B, and C). The concentration of inorganic ions (Ca, Mg, and P) decreased in all groups. Fattyacid composition was also analyzed by GC-MS and expressed as percentage of total fatty acid concentration. The content of palmitic acid decreased in all groups. The content of 2-hydrox-yhexadecanoic acid, which has not been reported in aster, increased in the top antlers of all groups. These results suggest that the treatment of special fodder may affect the composition of the biochemical components of antlers.
