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.

To evaluate training effect, aerobic dance was performed by eight female collegestudents for 8 weeks. Body composition, cardiopulmonary function at rest and during maximal exercise, blood cholesterol concentration at rest were determined before and after 8weeks of aerobic dance training. Maximal exercise was performed on the treadmill according of Bruce protocol. Pre to post training differences were evaluated. The results obtained were as follows : 1. After the training, skinfold thickness and total body fat decreased significantly(p＜0.1) while lean body mass increased with significance (p＜0.1). 2. Heart rate and arterial blood pressure at rest decreased without sinificance after the training. 3. As a result of training, forced vital capacity and forced expiratory volume for a second increased significantly (p＜0.01, p＜0.1). 4. After the training period, heart rate at 3, 6, and 9 min. during treadmill exercise was significantly lower than those of pretraining (p＜0.05). 5. After the training, systolic and diastolic blood pressure at 6 and 9 min during the exercise was significantly lower than those of pretraining (p＜0.025, p＜0.1). 6. After the training, oxygen uptake at 3 and 6 min during the exercise was significantly greater than those of pretraining (p＜0.05). 7. As a result of training, the maximal oxygen uptake increased significantly during the exercise (p＜0.1). 8. After the training, expired air volume for a minute at 3 and 6 min during the exercise was signigicantly grerter than those of pretraining (p＜0.1). 9. After the training, repiratory quotient during the exercise was lower than pretaining without significance. 10. After the training, blood HDL -cholesterol concentration incereased with significance, (p＜0.1) blood total cholesterol and triglycerids concentration decreasedsignificantly (p＜0.1). From these results, it may be concluded that 8 week aerobic dance training reduces skinfold thickness and body fat contents, improves the cardiopulmonary function and tissue oxygen utilization, reduces blood cholesterol and triglyceride concentration and brings about the increase of blood HDL-cholesterol concentriation.

Aims: To examine the pretreatment effects of regular aerobic training on the IGF system (IGF-I, IGFBP-3 and IGF/IGFBP) and doxorubicin(DOX) induced hepatotoxicity in rats. Materials and Methods: Forty-eight male rats were divided into groups:(1) control+placebo (2) $control+DOX_{10}mg{\cdot}kg^{-1}$ (3) $control+DOX_{20}mg{\cdot}kg^{-1}$ (4) training+placebo (5) $training+DOX_{10}mg{\cdot}kg^{-1}$ (6) $training+DOX_{20}mg{\cdot}kg^{-1}$. Hepatotoxicity was induced by DOX with dosages of 10 and 20 $mg{\cdot}kg^{-1}$. The rats in groups 4, 5 and 6 performed treadmill running of 25-54 min/day and 15-20 m/min, 5 days/wk for 6 wks. At the end of the aerobic training protocol, rats in the 1 and 4 groups, in the 2 and 5 groups and in the 3 and 6 groups received saline solution, $DOX_{10}mg{\cdot}kg^{-1}$ and $DOX_{20}mg{\cdot}kg^{-1}$, respectively. Results: Administration of $DOX_{20}mg{\cdot}kg^{-1}$ caused a significant increase in IGF-1 and IGF-1/IGFBP-3, an insignificant decrease in IGFBP-3, as compared to the control+placebo group. However, after six weeks of aerobic training and DOX treatment with $10mg{\cdot}kg^{-1}$ and or/ $20mg{\cdot}kg^{-1}$ an insignificant decrease in IGF-1, an insignificant increase in IGFBP-3 and a significant decrease in IGF-1/IGFBP-3 were detected, in comparison to $C+DOX_{10}$ and $C+DOX_{20}$. Conclusions: Hepatotoxicity of doxorubicin is dose-dependent and pretreatment with regular aerobic training may improve DOX-induced hepatotoxicity by up-regulation of IGFBP3.

Purpose : This study examined the effect of transcranial direct current stimulation (tDCS) combined high intensity interval training (HIIT) on the aerobic exercise capacity of college soccer players. Methods : The subjects of this study were 30 college soccer players. They were divided into a high intensity interval training group combining transcranial direct current stimulation (Group I) and a high intensity interval training group (Group II). Each group had 15 subjects randomly assigned. After receiving general soccer training, each group additionally received high intensity interval training combined with transcranial direct current stimulation and high intensity interval training for 30 minutes 5 times a week for 8 weeks. Their VO₂max and 20 meter shuttle run test, Yo-Yo intermittent recovery test were analyzed before the intervention. After 8 weeks of intervention, the above items were re-measured and an intergroup analysis was performed. Results : As a result of comparative analysis of VO₂max intake between groups, 20 meter shuttle run test and Yo-Yo intermittent recovery test, a statistically significant difference was found. The high intensity interval training group (Group I) combined with transcranial direct current stimulation showed a significant difference in aerobic exercise capacity compared to the high intensity interval training group (Group II). Conclusion : These results showed that high intensity interval training group combined with transcranial direct current stimulation was more effective for aerobic exercise. Based on this study, this study proposes an effective program for patients as well as elite athletes. In the future, it is necessary to develop an effective transcranial direct current stimulation program and to study how to apply it for various patients.

The purpose of this study was to investigate the effects of treadmill aerobic exercise training on isokinetic muscle strength in students with cerebral palsy. The subjects consisted of 9 female students with cerebral palsy between the ages of 10 to 22. The subjects performed treadmill aerobic exercise training with $0\%$ grade by free speed with three times a week for 20 minutes a session and 12 weeks. Concentric peak torque of knee flexors and knee extensors was measured before training and after training at $30^{\circ}/sec$ and $60^{\circ}/sec$ by isokinetic dynamometer. Paired t-test was used to assess changes in variables of isokinetic muscle strength. The results of analysis are as followings. 1) After training, concentric peak torque of the least affected knee flexors(p<.01) and the most affected knee flexors (p<.01) and concentric peak torque of the least affected knee extensors(p<.01) and the most affected knee extensors(p<.01) at $30^{\circ}/sec$ significantly increased. 2) After training, concentric peak torque of the least affected knee flexors(p<.05) and the most affected knee flexors(p<.01) and concentric peak torque of the least affected knee extensors(p<.05) and the most affected knee extensors(p<.01) at $60^{\circ}/sec$ significantly increased. These findings provide evidence that treadmill aerobic exercise training improves isokinetic muscle strength in students with cerebral palsy.

본 연구에서는 8주의 유산소 및 저항성 트레이닝 그룹으로 나누고 그에 따른 트레이닝이 서로 다른 테스트를 하였을 때, 운동 특이성 효과(specific effect)와 전사효과(transferabilty)에 영향을 미치는 지를 연구하였다. 결론적으로 8주간의 유산소 및 저항성 트레이닝은 동일한 테스트를 통하여 운동의 특이성은 나타냈으나 서로 다른 테스트를 해 봄으로써 전사효과의 향상은 나타내지 못했다. 전사효과를 나타내지 못한 가장 큰 이유는 8주라는 기간이 중추신경과 근육의 적응하기에는 다소 짧은 기간이라 사료되며 추후의 연구에서는 트레이닝 기간등을 고려한 좀 더 세분화된 연구가 필요하다고 생각된다.

[Purpose] The purpose of this study was to investigate the effect of diet plus exercise training and detraining for 12 weeks on body composition, aerobic performance, and stress-related variables in obese women. [Methods] Twenty-five women in their 20s-40s with 30% body fat and body mass indices above 25 kg/m² were divided into HR_LT (heart rate at lactate threshold) and HR_LT + 5% groups. Dietary intervention of 70% recommended dietary allowance (RDA) and exercise treatment composed of aerobic exercises on a bicycle (30 min) and treadmill (30 min) were then performed. These interventions were performed three times a week for 12 weeks. [Results] Dietary intake was significantly decreased, while daily activity significantly increased within the 12-week intervention period, and this effect was sustained after 12 weeks of detraining. Exercise training based on dietary intake and daily activity presented a significantly decreased weight and % body fat, improvement of aerobic performance, and a significant increase in heart rate variability (HRV) (e.g., average of all RR intervals and the square root mean squared differences of successive RR intervals) as stress-related variables. It was also confirmed that the improvement of body composition and stress-related variables were maintained even after detraining. [Conclusion] Our results suggest that 70% RDA of dietary intervention and exercise training corresponding to HR_LT and HR_LT + 5% for 12 weeks were effective in improving body composition and aerobic performance, and relieving stress. In particular, enhanced HRV persisted for up to 12 weeks after the end of exercise training in obese women.

Objective: Older adults with mild cognitive impairment (MCI) are more likely to progress to dementia. Motor-cognitive training is applied as a dual-task to improve the cognitive and physical functions of older adults with MCI. The purpose of the study was to know the recent trends in motor training types and outcome measures used for motor-cognitive training in older adults with MCI. Design: Aliterature review Methods: This literature review was conducted in Pubmed, MEDLINE® and Google Scholar with the following key words: older adults, mild cognitive impairment, motor-cognitive training, cognition, and dual-task. The 7 studies were found with the search tool and all studies were randomized controlled trials. Results: In motor-cognitive training in older adults with MCI, 6 studies applied aerobic exercise. And 3 out of 6 studies also applied strengthening exercises. One study applied dual tasks without aerobic exercise. In the 6 studies, overall cognitive and executive function were used as outcome measures, and physical function was evaluated as gait performance. Memory and physical frailty were also used as measurement tools. As a result of all studies, when motor-cognitive training was applied, cognition and physical performance showed significant results. Conclusions: A recent five-year study applied mainly aerobic exercise and strength training to older adults with MCI and found it to improve cognitive and physical performance.
