The purpose of this study is to examine the change of neruotrophins and brain fitness factors from constant physical activities and brain-activity increase for 12weeks. The subjects are 36 male students in early grades without any medical opinion. Also, three groups of PAG, BAG, NAG were secondary analyzed respectively. The following is the result. First, there has been the interactive effect involved with groups and repetitions in %bodyfat, HDL-C and VO2max. Second, there has been the interactive effect in BDNF and IGF-1 involved with groups and treatment. When it comes to VEGF, there was a small amount of increase but hasn't any statistic effect. Third, there was large increase in the group of the brain-activity in comparison with the group of the physical-activity and were significant statistic differences among treatments. After all the analysis, 12-week physical activity program in childhood turned out to have positive effect on neurotrophins. With physical activity and consistent physical activity, brain health can be developed by maintaining the normal range of metabolic risk factors and if physical and brain activities are properly conducted, it is considered that there must be possible synergistic effects of brain health development. In addition, were the causes of development and hindrance proven through a later study considering normal students, obesity, physical strength and even the factors of stress which children have it would provide the development of brain health for the growing up with very helpful materials.

This study was conducted to analyze the effect of changes in the targeted older female adults over 12 weeks of aerobic training and weight training exercises performed complex factors of obesity, metabolic risk factors and cognitive function. The subjects in the combined exercise group was set up in 10 patients, the comparison group in 10 patients, and examine the dependent variables before and after 12 weeks treatment program, the following conclusions were drawn. First, according to the combined exercise over the period of twelve weeks, the effectiveness of the movement with a statistically significant interaction in the body weight and muscle mass has been confirmed. Second, waist circumference over 12 weeks of treatment of metabolic risk factors, depending on the compound movements, represented a significant difference in diastolic blood pressure and triglycerides were statistically determine the effectiveness of combined exercise. Third, the motor 12 weeks of cognitive evaluation items according to the composite motion scoring speed, simple reaction time and indicated a statistically significant difference in the choice reaction time could determine the effectiveness of the combined exercise. As viewed by synthesis on these results, it was confirmed that applying a combined exercise to the older female adults have shown a partially positive effect on obesity and metabolic risk factors. In addition, cognitive functions are particularly effective because the overall neural response speed, as well as the frequency of nerve stimulation to improve forecasting exercise. If one can compare and analyze various fitness and metabolic risk factors in subjects relevant to future research and evaluate all of the details of cognitive function can be considered to make a more meaningful research.

The purpose of this study was to investigate the effect of running exercise training and walking exercise training for 12weeks on serotonin and cortisol of elderly Women. Subjects of this experiment were selected 21 elderly womens and they were assigned into two groups. One group was composed of 7 who participated in a running exercise, and the other group was composed of 7 who participated in a walking exercise. Both groups were measured factors before and after training; Running exercise program was composed of warm up(10min), running exercise(20min), and cool down(10min) performed 3 times per week. Walking exercise program was composed of warm up(10min), walking exercise(50min), and cool down(10min) performed 3 times per week. As a result, running exercise group was significantly increased in serotonin and significantly decreased in cortisol (p<.05). Also, walking exercise group was increased in serotonin and significantly decreased in cortisol (p<.05). In conclusion, these finding suggested that the running exercise and walking exercise were effective in decreasing symptom of depresson and stress.

The purpose of this study was to identify an effective exercise method by investigating the effect of rest time difference between sets during resistance training on the Isokinetic muscular function, Vo2max, and Body composition in the Middle aged women. For this study, 24 women in their 50s were subjected to 60sec rest time group of 8, 120sec rest time group of 8, and 180sec rest time group of 8. Analysis of ANCOVA was done using SPSS 19.0 for data processing. The results of this study are as follows: Isokinetic peak torque in Extensor showed no significant difference, but that in Flexor was significantly higher in 60sec rest time group than in 180sec rest time group. Muscle endurance in both of Extensor and Flexor was significantly higher in 60sec rest time group than in 180sec rest time group. Antioxidant enzyme in 180sec rest time group was higher than that in 120sec rest time group and it was higher in 120sec rest time group than that in 60sec rest time group. There was no significant difference in Body weight and Muscle mass between groups but %fat was significantly lower in 60sec rest time group than that in 120sec rest time group and 180sec rest time group.
