This study was to investigate the effect on the body composition and the physical fitness that is worked by the hypodermic fat. In oder to study, we got 90 of the 144 female students, who resides in Pusan area, divided into the under-weight, the normal-weight, and the over-weight group according to he hypodermic fat rate. And then they were inquired with four item of the body composition and six item of physical fitness. After producing the average and standard deviation, and operating the unitary variable analysis to verify the mean deviation we could find the conclusions as follows. 1. The hypodermic fat quantity and hypodemic fat percentage showed the significant difference by the oder of the over-weight, the normal-weight, and the under-weight group in the body composition classified with hypodermic fat. In agility and lbm, the under-weight and normal-weight group was significantly higher than the over-weight group. 2. In the muscular strength, the normal-weight was significantly higher than the under-weight in the physical fitness classified with hypodermic fat. The muscular endurance was significantly higher with order of the under-weight, normal-weight, and over-weight. In the muscular power, the under-weight was significantly higher than the normal-weight and the over-weight. In the balance there were no significant difference in statistics. In agility, the under-weight and the normal-weight was significantly higher than the over-weight. In flexibility, the under-weight and the normal-weight, over-weight was not significantly difference. Therefore, there was a tendency that the higher the hypodermic fat was, the lower the physical fitness in the group of the over-weight, the normal-weight and the under-weight. So, it was recommended that teenagers should improve their physical fitness and decrease their hypodermic fat rate with diet, etc. Also, it was important for us to understand exactly the hypodermic fat rate of the female students, and needs preventing fatness with the exercise program and the diet.

The objects for the research were gymnastics athletes who is belonged to the middle, high school and the university in gymnastic player who are registered in korean gymnastic association samples of 383 questionnaires by convenience sampling was used as final research materials. The results by using exploratory factor analysis, reliability analysis, multiple regression analysis, path analysis with SPSS 15.0 and AMOS 7.0 are as follow; First, transactional leadership has a positive influence on empowerment. Second, transformational leadership has a positive influence on empowerment. Third, servant leadership has a positive influence on empowerment.

This research let 90 of the 135 male students, who are in the third grade in the high school the Busan, divided into the under-weight, the normal-weight, and the over-weight group. with 30 students in each group, according to the level of the Hypodermic Fat Rate in order to investigate the body composition and Physical Fitness by the hypodermic Fat distribution of the male high School Students, and examined in the body composition 4 and Physical Fitness 6 lists. This shows the following conclusion. After I was produced the average of a dependent variable of the hypodermic fat quantity and rate and standard deviation, to verify the mean deviation, and unitary variable analysis came into effect. This shows the following conclusion.1. The hypodermic fat quantity and rate shows the obvious difference by order of over-weight, normal-weight, under-weight in the body composition by the hypodermic(P< .001), but the lbm quantity and juices doesn`t show that statistically(P >.05).2. The muscular fitness of the over and the norma groups is higher than obviousdifference from the former and the latter in the Physical Fitness by the hypodermicfat distribution(P<.01). muscular endurance and gility of the under groups is thenormal groups and higher than that of the over one, there is the obvious difference as well(P<.001). muscular power the under groups, normal groups, higher then that of the over one, there is the obvious difference as well(P<.001). There isn`t any difference statistically in balance and flexibility(P<.05).Therefore, among the under-weight, the normal-weight and the over-weight group, because the higher the hypodermic fat rate is, the lower the physical strength of students grows, teenagers should improve their health and decrease their hypodermic fat by doing exercise and a dietary treatment.

This shows the following conclusion. 1. The hypodermic fat quantity and rate shows the obvious difference by order of over-weight, normal-weight, under-weight in the body composition by the hypodermic(PK001), but the lbm quantity and juices doesn't show that statistically(P>.05). 2. The muscular fitness of the over and the norma groups is higher than obvious difference from the former and the latter in the Physical Fitness by the hypodermicfat distribution(PK01). muscular endurance and gility of the under groups is thenormal groups and higher than that of the over one, there is the obvious difference as well(P<.001). muscular power the under groups, normal groups, higher then that of the over one, there is the obvious difference as well(P<.O01). There isn't any difference statistically in balance and flexibility(P>.05). Therefore, among the under-weight, the normal-weight and the over-weight group, because the higher the hypodermic fat rate is, the lower the physical strength of students grows, teenagers should improve their health and decrease their hypodermic fat by doing exercise and a dietary treatment.

This research was conducted to predict the relative impotance of physique and physical fitness in male elite gymnastic athletes affecting gymnastic performance. The total number of research subject was 30, 10 national team members and 20 regular members. We got following conclusions through T-verification and multiple regression analysis by gradational input system.
