The purpose of this study was to compare and examine effects yoga and walking exercise on cardiovascular risk factors, biomarkers of aging, and stress hormones of obese elderly males, and to provide basic data for health promotion of obese elderly men. The subjects in this experiment were divided into the exercise group (n=15) who carried out 16-week program of yoga and walking exercise and the control group (n=14). First, regarding cardiovascular risk factors, exercise group showed significant changes in TC(p<.01), HDL-C(p<.05), LDL-C(p<.05), and SBP(p<.05). Second, exercise group showed significant changes in Melatonin(p<.05) regarding biomarkers of aging, and in ACTH(p<.05) and cortisol(p<.05) regarding stress hormones. In conclusion 16-week yoga and walking exercise, for 4 days per week and 1 hour per day, is effective for reduction of cardiovascular risk factors and increase of Melatonin and stress hormones of obese elderly males. Therefore, it is considered that 16-week yoga and walking exercise treatment can be used to present basic educational data with respect to development of exercise program for obese elderly men. In future, it is necessary to conduct researches about long-term yoga and walking exercise, and about stress hormones of obese elderly women who are not familiar with exercise.

The purpose of this study is to verify physiological effects of yoga exercise and using public transportation, and to provide basic data for health promotion of obese elderly males through a comparative analysis of obesity indices, inflammatory reactions, stress hormones and physical activities of obese middle-aged white-collar male workers. The subjects in this experiment were divided into two groups: a group (n=11) who carried out 12-week program of yoga exercise and using public transportation and the other group (n=10) using their own cars. There were significant differences in body mass index (BMI) (p<.05), body fat percentage (p<.05), belly (p<.05), and daily steps (p<.01) between two groups. There were significant differences alos in IL-6 (p<.05), TNK-a (p<.05), CRP (p<.01), ACTH (p<.05), and cortisol (p<.05) between two groups, and there was a significant relationship between physical activity and (BMI) (p<.05), body fat percentage (p<.05), belly (p<.01), CRP (p<.01), and cortisol (p<.05). Therefore, it is considered that 12-week treatment of yoga exercise and using transportation can be used to present basic educational data with respect to development of exercise program for health promotion of obese elderly men.

The purpose of this study was to examine the effects of a 12-week weight and plyometric training on 30°/sec lumbar joints and 180o/sec knee joints, and to provide basic data for lumbar joints and knee joints of pitchers and fielders. The subjects in this experiment were high school baseball players who were registered in Korea Baseball Association (KBA), First, there were differences in peak toque (p<.01) and peak toque % weight (p<.05) of flexors and percentage of average power to body weight (p<.05) of extensors at 30o/sec lumbar joints between pitchers and fielders. Second, there were differences in peak toque and peak toque % weight (p<.05) of extensors and peak toque % weight and average power (p<.05) of flexors at 180o/sec right knee joints between pitchers and fielders. Third, there were differences in peak toque and peak toque % weight (p<.05) of extensors and average power (p<.05) of flexors at 180°/sec left knee joints between pitchers and fielders. Consequently, high school pitchers and fielders should conduct post-season weight and plyometric training, and data selection about high school baseball players will be very helpful to baseball coaches and trainers. Moreover, for better performance of condiered necessary to select basic data on maximum isokinetic muscle strength of lumbar joints and knee joints is required during postseason. In future, analysis of high school pitchers by age group will be conducted.

Second, according to income status backgrounds higher players with higher income backgrounds had higher physical management levels among other elements of self management. In addition, income status backgrounds had the highest influence on training management(Eta2=.66). Third, health status had shown to have the highest effect on physical management whereas the difference in health status had the highest influence in training management((Eta2=.80). Fourth, in terms of training periods interpersonal relationship strategy had shown to have the highest influence.
