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.

The purpose of this study was to compare and to verify isokinetic leg muscle functions between various types of female athletes. The subjects of this study were 53 female players, which consisted of 10 weight lifters, 11 swimmers, 11 handball players, 11 tennis players, 10 athletes. Isokinetic concentric and eccentric contraction in the knee joint extensor and flexor, and the ankle joint extensor and flexor were examined at the angular velocities of both 60°/sec. For statistical analysis, one way ANOVA was used and significant level of 0.5 was selected. With the above experimental process, the results were gained as follows: 1. The peak torque per BW showed a statistically significant difference between all the groups in the knee joint concentric flexor and extensor at the angular velocity of 60°/sec. 2. The peak torque per BW showed a statistically significant difference between groups in the knee joint eccentric flexor at the angular velocity of 60°/sec. Whereas, there was no significant difference in the knee joint eccentric extensor at the angular velocity of 60°/sec. 3. The peak torque per BW showed a statistically significant difference between all the groups in the ankle joint concentric flexor and extensor at the angular velocity of 60°/sec. 4. The peak torque per BW showed a statistically significant difference between all the groups in the ankle joint eccentric extensor at the angular velocity of 60°/sec. Whereas, there was no significant difference in the ankle joint eccentric flexor at the angular velocity of 60°/sec.
