The purpose of this study was to analyze the effects of 8 weeks combined exercise program on body compositions and isokinetic leg muscular strength and the correlation between body compositions and isokinetic leg muscular strength in elderly women (age>65, n=20) by fat percent (%fat). The participants was divided into two groups; normal group (NG, n=9, body fat<30%) and obesity group (OG, n=11, body fat>35%) and was performed the combined exercise program lasting 8 weeks(3 times/week, 60min/day). As a result are as follows; Body compositions and isokinetic leg muscular strength have not the significant interaction (group x time)(p>.05). After training, however, there were the significant increase of lean body mass, skeletal muscle, upper limb muscle and trunk muscle in NG (p<.05), but of upper limb muscle and trunk muscle in OB (p<.05). And after training in both groups, there were the significant elevation of peak torque of extensor and flexor of left and right leg and mean power of extensor and flexor in right and left leg (p<.05). Only however, in NG, there were the significant elevation of total peak torque of extensor and flexor in left leg and mean power of extensor and flexor in left leg after training (p<.05). Before training there were no the significant correlation between body compositions and isokinetic leg muscular strength, but after training there were the significant correlation between skeletal muscle and appendicular skeletal muscle was corrected for body weight (ASM/body weight; ASMW) and isokinetic leg muscular strength (p<.05). And, regardless of obesity, ASMW may be predict the possibility of total (left+right) peak torque of extensor (47.9%) and flxeor (37.4%) and total (extensor flexor) peak torque of right leg (38.3%) and left leg (53.2%) in elderly women. In conclusion, eight weeks training period was not enough to improve the positive changes of body composition in elderly women. However, combined exercise training has the effect of Isokinetic muscular strength improvement in elderly women.
