The effects of exercise on immune function unclear. The purpose of this study was to investigate the changes of lymphocyte proliferation, NK cell and TNF-a concentration after 16weeks combined training. Subjects were composed of fourteen obese middle-school students. The training program was separated treadmill running and muscular resistance training. The treadmill running was composed of 60%HRmax, 30 minutes per day, 4 days per week. The muscular resistance training was composed of 60% of 1RM, 40 minutes per day, 4 days per week, 2-way repeated ANOVA was used to evaluate the difference among group and pre and post 16 weeks. The 0.05 level of significance was as critical level for the study.The body weight and %body fat were significantly decreased. And lean body mass and VO<sub>2</sub>max(㎖/㎏/min)was significantly increased after combined training. Also, lymphocyte proliferation and NK-cell were significantly increased after combined training. Both of TNF-α and IL-6 concentration were decreased. And insulin concentration were decreased after combined training.In conclusion, combined training was shown to positive influence on body composition, lymphocyte proliferation and NK cell. In particularly, decreased TNF-α and IL-6 concentration was affect insulin concentration. Therefore, it is maybe thought that combined training was important role for obesity treatment.
