Abstract
The purpose of this study was to determine the effect of 12 weeks exercise program on body composition, aging and metabolic related blood variables, and HOMA-IR in obese older women. BR 32 obese older women participated in the study. Participants were randomly divided into three groups; combined exercise group(n=11), aerobic exercise group(n=11), resistance exercise group(n=10). Participants were tested before and after the 12 weeks exercise program for body composition, fitness, blood variables.BR As a results, In body composition, weight, fat mass, body fat percentage decreased significantly in all groups(p.05), while lean mass increased in the combined and resistance exercise group(p.05). Glucose, insulin, triglyceride and HOMA-IR decreased in all groups(p.05), while DHEA-S and HDL-C increased in all groups(p.05). Meanwhile, estrogen increased only in the combined exercise group(p.05).BR In conclusion, the combined exercise consisting of aerobic and resistance exercise would be more helpful in improving lean mass, strength, estrogen compared to single type of exercise, suggesting that combined exercise would be an effective treatment for obese older women in improving obesity.BR
