[PURPOSE] The purpose of this study was to determine the influence of complex exercise and vitamin D intake on body composition, physical fitness, bone density, and obesity hormone in obese middle aged women. [METHODS] The subjects were 32 obese women 30% of body fat, 8 placebo group (PL), 8 complex exercise with placebo group (CE+PL), 8 complex exercise with high vitamin D intake (CE+LV), and 8 complex exercise with high vitamin D intake group (CE+HV). The subjects have performed the exercise program for 70 minutes a day and 3 times a week with weight training and elastic band exercise during 12 weeks. Also, low and high vitamin D intake group took a peel 2.5ug(100IU) and 10ug(400IU) respectively at the same time and place. [RESULTS] There was a significant decrease in body fat to CE+HV compared with CE+PL and PL (p<.05) and significant increase in muscular strength, muscular endurane, and flexibility between groups compared with PL (p<.05) but not in cardiorespiratory endurance(p>.05). Also, There were significant increases in part of upper arm, thigh, and lumbar of bone density(p<.05). For the obesity hormones, leptin and insulin significantly decreased in CE+HV compared with CE+LV, CE+PL, PL(p<.05) and there was a significant increase in ghrelin(p<.05). [CONCLUSIONS] In conclusion, there were positive responses in muscular endurance and bone mineral density, in cases involving both complex exercise and high vitamin D intake, from the development of body composition and obesity hormones
