We divided the high-school girl students into short-distance group (dormitory within 200m)and long-distance group(average 3.66㎞). We surveyed the effects of their on-foot school attendance upon their heights, their weights, and the distribution of fat-body. The results of the study for one year and eight month are as in the following: 1. As results of height measurement of the groups, it was found that there was no significant difference between short-distance attendance group and long-distance attendance group. 2. As results of weight measurement of the group, it was shown that there was significant difference between short-distance attendance group and long-distance attendance group, and that the weight of students of long-distance attendance group was lower than that of short-distance group. 3. As results of fat-body measurement of group, it was revealed that there was significant difference between short distance group and long distance attendance group, and that the fat-body of students of long-distance attendance group was lower than that of short-distance group.

The purpose of this study was to examine the awareness of students taking general P.E. courses in winter sports about the courses and their satisfaction level by utilizing Martilla & James(1977)"s IPA-based importance-satisfaction analysis. The subjects in this study were 449 college students. As for data analysis, descriptive statistics analysis, exploratory factor analysis, confirmatory factor analysis, paired-samples test and IPA analysis were utilized. The findings of the study were as follows: First, the students investigated placed the most significance on product?price?place?promotion?people?physical evidence?process?the professional knowledge of professors?awareness of seasonal sports?the integrity of professors?their teaching effec?improvement of practical skills?the content of lectures?easy-to-understand teaching?the effect of lectures?the type of seasonal sport, improvement of theoretical knowledge and traffic convenience among the selection attributes of general P.E. courses in winter sports, In terms of satisfaction attributes, they gave the most weight to the integrity of professors?followed by improvement of theoretical knowledge?the professional knowledge of professors?awareness of seasonal sports?the effect of lectures?the teaching effects of professors?easy-to-understand teaching?improvement of practical skills?traffic convenience and the diversity of seasonal sports. Second, in the case of sustainability attributes in the quadrant I, they placed significance on the integrity of professors, their professional knowledge, their teaching effect, the effect of lectures, easy-to-understand teaching, improvement of practical skills?improvement of theoretical knowledge?the type of seasonal sport and reasonable price. Third, they gave weight to the diversity of seasonal sports among the attributes in the quadrant Ⅱ that required improvement. Fourth, they pointed out convenience of accommodations?reasonable price?program management?publicity of program schedule?publicity of lectures" safety of facilities?satisfaction with the place and satisfaction with the equipment among the attributes in the quadrant Ⅲ that weren"t top priorities. Fifth, they placed significance only in place accessibility among the attributes in the quadrant Ⅳ that would not require excessive efforts. The findings of the study indicate that the number of general P.E. courses on winter sports will be on the rise if the courses are offered in consideration of the attributes that students have chosen in importance-satisfaction analysis.

The purpose of this study was to compare the maximum strengths, the flexor and extensor ratios, and left and right differences between the isotonic maximum strength(IRM) and the isokinetic peak torque at the knee joint. The subjects of the experiment were consisted of early twenties male university students in Seoul Korea without disabilities. The average age of subjects was 21.70 with ±3.34 deviations. The results of this study were shown as followed : 1. The correlation of extensor between test machines showed r=.676(p<.001) on left, and r=.600(p<.01) on right. Flexor showed r=.770(p<.001) on left, and r=.674(p<.001) on right. The significance statistically showed high correlations between isotonic one repetition maximum and isokinetic peak torque. 2. The deviations of strengths between left and right muscles were not significantly different on both test machines. 3. The differences between flexor and extensor ratios were not significantly different on both test machines. The results of these data suggests that IRM of isotonic test was predicted factors of isokinetic peak torque. Thus, we hope the field exercise specialists to reference for management of exercise participants.

This study is conducted to compare the problems affecting dietary habits and health status between a long-term exercise group and non-exercise group of males older than 50 years. Most subjects of the two groups consider regular exercise to be the most important factor for maintaining health, and recognize hypertension as the number one concern. The most common nutritional supplement among subjects is multiple vitamins, and sleeping time range from 6~8 hours. Breakfast fasting rate was 15.9% among non-exercise group (NEG), where overeating and eating out rates were higher among exercise group (EG) when comparing to NEG. Fasting rates of breakfast, and consumption rates of milk and dairy products, vegetables such as kimchi, and fruits and fruit juices are higher among the EG. Overeating and eating out rates are lower among NEG, whereas eating rates of proteins like meat, fish, eggs, beans, fried foods, high-fat meats carbonated drinks, ice cream, and salt intakes are higher. Rates of health, dietary habits, and nutrient intakes are higher among EG. Energy intakes among the two groups were below the standard level, Vitamin B2 intake is low in EG, and folic acid and calcium intakes were higher in NEG. The exercising group care more about health, eating habits and nutrient intakes, and low smoking rates are being observed. Thus, specific dietary improvement programs for adult men, are required, and it is necessary to consider the practice of nutrition education.

The purpose of this study was to investigate the difference in physique, physical fitness and isokinetic strength of Forward(FW=10) and Defense(DF=9) in Korean professional ice hockey players. The subjects selected for this study were composed of nineteen male professional ice hockey players. They didn`t have any previous medical or physical problems. They were measured physique, body composition, physical fitness and isokinetic knee strength test. All of data were analyzed utilizing independent t-test by SPSS 10.0. The level of statistical significance was set at p<.05. On the basis of the results analyzed in this study, the conclusion was as follow: 1. The variables of body composition were no significant differences between ice hockey FW players and DF players. 2. In physique variables, the height of ice hockey DF players was significant higher than FW players and remainders of physique variables were no significant differences between both groups. 3. The level of physical fitness variables were no significant differences between ice hockey FW players and DF players. 4. In knee isokinetic strength test, the peak torques of flexor and extensor in a left knee joint of ice hockey between DF and FW players were not significant different, but the peak torques of flexor and extensor in a right knee joint of ice hockey DF players were significantly higher than those of FW players. In conclusion, ice hockey players have the difference in physique and isokinetic knee strength between FW and DF players. Therefore, it is very important that the player should be trained up considering their characteristics according to the players` position.
