Purpose : The purpose of this research is to examine the effects of circuit weight training and aerobic exercise on the bodily formation and abdominal fat area of obese female college students. Methods : The female college students whose BMI is over $25kg/m^2$ were divided into the circuit weight training group and the aerobic exercise group and circuit weight training and aerobic exercise were conducted on the respective group five times a week. Resultlts : 1. The tendency of statistically significant reduction in weight, body fat percentage, and BMI was shown in both the circuit weight training group and the aerobic exercise group but there were no significant differences between these groups. 2. The tendency of statistically significant reduction in total abdominal fat area, and subcutaneous fat area was shown in both the circuit weight training group and the aerobic exercise group but there were no significant differences between these groups. 3. Visceral fat area was reduced more in the aerobic exercise group than in the circuit weight training group Conclusion : It was confirmed that exercise alone in the state of no dietary treatment being given could cause obese people bodily formation.

본 연구는 중년여성을 대상으로 12주간 순환근력운동이 신체구성성분과 기초체력에 어떠한 영향을 미치는지를 분석하기 위해 실시되었다. 최근 6개월 동안 규칙적으로 운동을 하지 않았으며, 질병 및 신체적 이상소견이 없는 중년여성 34명을 대상으로 12주간 순환근력운동을 실시하였으며, 신체구성성분검사와 기초체력검사항목으로 평가하였다. 결과에서 신체구성성분검사는 체중, 체지방률, 허리둘레 모든 항복에서 통계적으로 유의한 차이를 보였으며, 기초체력측정에서는 악력과 제자리멀리뛰기에서 어느 정도의 향상을 보이기는 했지만 통계적으로 유의한 차이가 나타나지 않았다. 그러나 상대악력, 앉아윗몸 앞으로 굽히기, 교차윗몸일으키기, 10m왕복달리기, 20m왕복오래달리기에서는 통계적으로 유의한 차이가 나타난 것으로 보았을 때, 12주간의 순환근력운동이 중년여성의 신체구성성분과 기초체력에서 효과를 보여 비만 개선과 체력증진을 위한 운동프로그램으로 권장될 수 있을 것으로 사료된다.

The purpose of this study was to investigate changes in heart rate according to recovery methods after circuit weight training exercise. Fourteen men in their twenties were selected as subjects, and three sets of circuit weight training were performed by cycling six sports, and two recovery conditions (dynamic and static) were performed immediately after exercise. Changes in heart rate did not have an interactive effect according to recovery method and time, and both conditions showed significant changes between sets 1 and 2, and between sets 3 and after recovery. In this study, the high heart rate of 2 sets and 3 sets was seen as a result of exercise stimulation, and the low heart rate of 1 set was thought to be due to the decrease in vagus nerve activity rather than the role of catecholamines. On the other hand, the heart rate after 20 minutes of exercise did not show any difference according to the recovery method, which could mean that the recovery process due to the aquatic environment can act more strongly than the process of dynamic recovery and static recovery. It is thought that the characteristics affected the sensory and circulation of the body, and thus the change of the afferent signal and the level of metabolic products generated in the active muscle.

The purpose of this study was to investigate the effects of circuit weight training(CWT) on isokinetic muscle strength and body composition in elderly. The subjects who engaged in this experiment exercised at 40$\%$ of 1-RM, 12 repetitions, followed by 15 sec as the subject moved to the each break training program which was consist of the circuit of 10 stations performed on 3 set a day, circuits 3 days a week during 10 weeks. The assessment of isokinetic factor was in concentric flexors and extensors of right and left knee joint. Tests were performed on the Cybex 770 Isokinetic Dynamometer and body composition were estimated the three parts of chest, abdomen and anterior thigh by using skinfold caliper, calculated the average and followed by Seri and Brozek way. Statistical analysis were performed using analysis of variance paired t-test, accepting level for all significant was above $\alpha$=.05 and $\alpha$=.01. Following is as a result of 10 weeks circuit weight training. 1. At the $60_{\circ}$ /sec, the right and left knee isokinetic concentric flexors and extensors peak torque increased significantly (p < .01). 2. At the $180_{\circ}$ /sec, the right and left knee isokinetic concentric flexors and extensors peak torque increased significantly (p < .01). 3. At the $60_{\circ}$ /sec, the right and left knee isokenetic concentric flexors and extensors average power increased significantly(p < 0.5, p < .01) and at the $180_{\circ}$ /sec, the right extensors didn't show any statistical significant. 4. At the $60_{\circ}$ /sec, the right and left knee Isokinetic concentric flexors and extensors total work increased significantly(p < .05, p < .01) but at the $180_{\circ}$ /su right concentric flexors didn't show any statistical significant. 5. The body composition changed significantly(p < .01). These results suggest that 10 weeks circuit weight training increases the peak torque, average power, total work significantly and decreases the $\%$body fat significantly.

Purpose : The purpose of this study was to determine the effects of 12 weeks of circuit training on inflammatory markers, blood lipids, and body composition of obese middle-aged women. Methods : Twenty-four obese women were randomly divided into three groups (circuit exercise training, CT; aerobic exercise training, AT; resistance exercise training, RT). All the subjects participated in the exercise program for 60 minutes, 3 times a week for 12 weeks. Results : Significant differences found in the participants pre-and post exercise training C-reactive protein (CRP), fibrinogen, and adiponectin levels. The CT participants experience an expected increase in their adiponectin levels. Significantly improved blood TC, LDL-C, HDL-C, and TG levels were found after 12 weeks of exercise. The AT and CT groups showed greater improvements in their HDL-C, LDL-C, and TG levels than the RT group. Significant differences were found in the participants pre-and post-exercise training body weight, body fat percentage, and body mass index (BMI). Conclusion : The CT participants body fat percentages decreased more than the RT group's percentages. In conclusion, obese women who completed 12 weeks of circuit exercise training (aerobics + resistance exercise) had significant improvements in their inflammatory markers, blood lipids, and body fat percentage.

PURPOSE: The purpose of present study was to determine effects of circuit class training (CCT) on the synthesis of central serotonin in people with post-stroke depression. METHODS: Forty patients with mild post-stroke depression were participated in current study. All subjects were assigned to two groups of CCT (circuit class training) group and SW (stretching and weight shifting) group. Both groups were performed for 80 minutes. The change of blood f-Trp, BCAAs, f-Trp/BCAAs and serotonin according to period training time were examined and the following results were obtained. RESULTS: In the CCT group, f-Trp, BCAAs, and f-Trp/BCAAs increased according to the time point. However, after 24 hour of circuit class training, all of these were significantly decreased by those before training. The change in blood levels of serotonin was the highest in immediately after the training in the CCT group while it was not changed significantly in the SW group. CONCLUSION: It can be seen that CCT can change the serotonin level and have an effect on the synthesis of central serotonin in people with post-stroke depression.
