The purpose of this study was to examine the effect of aerobic exercise on blood lipids, lipoprotein, and body composition in college women. The subjects consisted of 12 obese women, possessing greater than 30% body fat and all of them had no other complications. Subjects participated in bicycle ergometer exercise program for 8 weeks according to the exercise treatment. They started to exercise for 55 minutes per day, 4 times a week at 65% of V˙O₂max. The results were obtained as followings, first, body weight(p$lt;.05), fat weight(p$lt;.001), %body fat(p$lt;.001), and waist-hip ratio(p$lt;.001) were significantly decreased after exercise treatment. However, soft lean body mass was significantly increased after exercise treatment(p$lt;.05). Second, total cholesterol and LDL cholesterol were not significantly decreased, and HDL cholesterol was not significantly increased after exercise treatment. However, triglyceride and total cholesterol/HDL cholesterol ratio were significantly decreased after exercise treatment, respectively(p$lt;.05, p$lt;.05). Results of the study indicated that aerobic exercise could change a body composition in obese college women through during 8 weeks. The effects of aerobic exercise of obesity treatment proposed in this study was appeared positively, but there was no significant difference in blood lipid and lipoprotein profile except in triglyeeride concentration and total cholestero/HDL cholesterol ratio. Thus, the study of blood lipids level suggests that there is a more clear effects of exercise, if increased exercise period.

The purpose of this study was to know about how the lower limb functional exercise in an unstable ground affects the lower limb strength and the balance ability of encephalopathy teenagers. In order to achieve the purpose of the study, the lower limb functional exercise in an unstable ground from 12 encephalopathy teenagers in the experimental group was applied once every 50 minutes twice a week during 12 weeks, meanwhile 12 encephalopathy teenagers in the control group did not receive any treatment except daily life. In order to evaluate the lower limb strength and the balance ability of the study subjects from exercise before and after exercise, the lower limb strength test using therabands, static balance ability test(standing by one leg, FRT) and dynamic balance ability test(TUG, walking 10 m, walking 3 m) were used. The results of this study through applying 2×2 mixed design two-way ANOVA as follows: First, the measured results of the lower limb strength using therabands was that the bending force and new force of a hip joint increased significantly(p=.000), also the bending force and new force of the knee joint increased significantly(p=.000). Second, in the static balance ability, standing by one leg with opened eyes and functional arm stretching(FRT) increased significantly(p=.000, p.002) respectively. Third, in the dynamic balance ability, in standing up and walking(TUG) and in walking straight 3m(Tandem Gait Test) decreased significantly(p=.000, p=.000), in walking straight 10m(Straight Walking Test) appeared no change. Taken together the above results, the lower limb functional exercise in an unstable ground during 12 weeks is believed to improve the lower limb strength and also static and dynamic balance ability of encephalopathy teenagers.

The purpose of this study was to compare physiological and metabolic variables during exercise which include maximal fat oxidation exercise intensity(MFOEI), 40%VO₂max and 60%VO₂max for lasting 40min on cycle ergometer. 1en healthy volunteers(age, 19.7±1.06years; height, 175.2±5.86㎝, weight, 68.7.±6.05㎏, body fat, 13.4±2.75%) served as subjects after signing an informed consent form. Following an overnight fast, subjects completed maximal graded exercise test to determine MFOEI, and submaximal exercise test at difference exercise intensities on separate days. To determine MFOEI, it was used on the cycle erogmeter(2-min stage, 25W increments). Expired gases were collected and analyzed each 1 min using QMC(USA) metabolic cart. The maximal fat oxidation exercise intensity(MFOEI) was defined as the intensity which resulted in maximal fat kilocarolies per minute(Fkcal) as determined by converting VO₂ to Fkcal at each cycle exercise stage using RER and a Lusk table. MFOEI by maximal graded exercise test on the cycle ergometer was 37.5±11.52VO₂max. Physiological and metabolic variables at difference exercise intensities(MFOEI, 40%VO₂max, and 60%VO₂max) was compared using One way repeated ANOVA. Significance was set at P$lt;0.05. VO₂(1.36±0.13, 40%VO₂max; 1.37±0.41, MFOEI and 2.01±0.17ℓ/min, 60%VO₂max) and, total kilocarolies per min(Tkcal)(6.49±0.61, 6.58±2.08, and 9.76±0.78kcal/min, respectively) were significantly highest at 60%VO₂max(p$lt;.05). RER(0.79±0.01, 40%VO₂max; 0.82±0.05, MFOEI and 0.84±0.04Kcal/min, 60%VO₂max) was significantly highest at 40%VO₂max(p$lt;.05). However, Fkcal and percent of fat oxidation were not significantly different at three intensities exercise. Since percent of fat oxidation was higher with 40%VO₂max compared with 60%VO₂max, while Tkcal was higher at 60%VO₂max than 40%VO₂max during 40min exercise, Fkcal was similar at difference exercise intensities. In conclusion, exercise prescription for weight control should be included factors such exercise intensity, exercise duration and exercise mode.

This study aims to investigate how various athletic meetings have been developed in the introduction and settlement of Korean modern physical education and how the characters appeared according to the period have been. As there was a quickening of modern physical education, and various athletic meetings were held giving the first consideration to athletic sports, the athletic meetings were at the height of prosperity and the modern athletic sports were practiced, spread by missionaries. These athletic meetings contributed to not only performing the education like the import and introduction of modern culture and the inspiration of patriotic sentiment, including games, amusements and speech meetings. It was the bitters of our physical education to be modernized by the need of Japanese exploitation of the colony for 35 years of Korean and Japanese annexation. In the athletic sports at that time, overseas brethrens and students studying abroad attended and spread the skills to Korean society and athletes. And introducing new sports, they performed great services in the promotion of domestic physical education. On the other hand, our athletes won prizes at the international Olympic games, and Son, Kee-Jeong, a marathon runner won a gold medal at the Berlin Olympic games. So it contributed to the inspiration of our national consciousness in the gloomy period. When Japan invaded the continent in 1930, they revised physical education with the kinds of fight training, in other to strengthen the policy of physical education to militaristic war structure. Therefore, it was very hard time in our physical education. As the autonomy at physical education was restored with liberation in 1945, every physical education organization was adapted for the international situation through the medium of sports and activated domestically international athletic meetings and each sort of athletic meetings in other to improve competition power. Also internationally, they sent athletes to various international tournaments including Olympic games and Asian games, and enhanced the nation's prestige abroad. The epoch-making promotion of physical education was made at the height of Seoul Olympic games in 1988.

This study examined the effects of 8-week plyometric training on isokinetic muscle function and vertical jump in the lower limb. These parameters were compared before and after training. The subjects of this study were participated in plyometric training calss who were physically trained university students. Plyometric training was performed at 5 exercise type for 30minutes per day, three days per week. The results of repeated measurement t-test showed that knee flextion and extension of CON were not significantly changed. However, knee flextion of ECC were incresed significantly for 120°/sec and 180°/sec, respectively. Knee extension of ECC were increased significantly for 60°/sec and 120°/sec, respectively. There were significant differences between pre and post tests on vertical jump. The results suggest that plyometric training was effective for increasing vertical jump.

The purpose of this study was to predict % body fat by usig body compositional parameters, and to find optimal equation for estimating the level of obesity and muscle mass. The subjects of this study were 237 female college students, and they were divided into 3 groups according to their weight level; 67 for low body weight group, 151 for normal weight group, 55 for overweight group. We used body composition analyzer(In Body 2.0, Korea) to perform the test. All the subjects were made not to eat or to drink during 12 hours prior to the test. For data analysis, multiple regression was performed. From this study, we could conclude as following; 1.The % body fat of our subjects was 28.48±5.03%, this value appeared to be somewhat higher than normal limit(25%). Muscle mass was 3.3kg less than normal, but fat weight was 2.93kg higher than optimal value. The ratio of waist and hip circumferene(WHR) appeared to be .81± .31. 2.The muscle mass in upper extremity, lower extremity, and trunk appeared to be 0.32kg(8.02%), 0.59kg(4.62%), 2.19kg(11.61%) lower than normal value, respectively. 3.It is noticeable that, 73.7% of total sub. lects had a tendonly of obesity, and 44.8% of low body weight subjects also appeared to be little obese. 4.The WHR seemed to be important parameters for estimating % body fat, considering that, when using WHR, height and weight as independent variables, the % body fat was more predictable than other methoals in this study.

Jun,Jae-Wan,Ko,Sung-Sick 서원대학교 응용과학연구소 1999 응용과학연구 Vol.8 No.1

The purposes of this study were to compare the effects of 3 weight control program, and to verify which one was most reasonable and effective method. The 18 female collegiate students, who were the residents in the same dormitory, participated as the subjects of this study, and were divided randomly into 3 groups; DR-group(dietary restricted group), LI-group(low intensity group), and HI-group(high intensity group). For both exercise groups, the caloric intake was 2000kcal per day, and energy consumption during exercise was 300kcal per day for 4 days, totally 1200kcal per week. For DR-group, the energy supply was limited to 1800kcal a day for 6 days so that the amount of negative energy balance could be with the exercise groups. LI-group and HI-group performed bicycle ergometer exercise at the intensity level of 50% VO?max for 70minutes, and 80% VO??max for 40 minutes, respectively. The dependant variables in this study considered of body composition. To compare the difference of body composition among 3 groups, 3×3 combined design two-way ANOVA and one-way ANOVA were used. The statistical significance was set at .05. The results were obtained as followings. First, fat weight and % body fat decreased significantly in each group. On the other hand, body weight was decreased in both DR-group and LI-group except in HI-group. However, soft lean body mass was increased in both HI-group and LI-group except in DR-group. Results of the study indicated that all 3 methods were effective for decreasing body weight. However, the dietary restriction was not advisable for its harmful effect, the decrease of LBM. The differences existed between the effects of exercise intensity. The low intensity exercise was helpful for decreasing body weight and for increasing LBM whereas the high intensity exercise did not cause the significant change of body weight. It was due to the increased muscle mass following the high intensity exercise. The high intensity exercise increased LBM. It was concluded that the high intensity exercise may be used for those who are obese and lack of muscle without any cardiopulmonary diseases.
