The purpose of this study was to investigate the characteristic analysis of knee joint isokinetic muscular strength according to BMI (body mass index) in elderly women. The eighty-six elderly women over 65 ages involved voluntary in this study. They were separated normal (18.5~22.9 ㎏/㎡, n=14), overweight (23~24.9 ㎏/㎡, n=16), class 1 obesity (25~29.9 ㎏/㎡, n=34), class 2 obesity group (30~34.9 ㎏/㎡, n=22) by BMI. The data was analyzed by using descriptive statistics, one-way ANOVA, and Scheffe post-hoc. The results of our study are as follows : 1) Peak torque at 60°/sec was the highest in the overweight group and the lowest in the class 2 obesity group. Peak torque % body weight showed similar trends in the normal and overweight groups, followed by the class 1 obesity group and the class 2 obesity group. 2) Peak torque at 180°/sec was higher in the class 1 obesity group than the class 2 obesity group in the left extensor and right flexors. Peak torque % body weight was found to be higher in the normal weight group, the overweight group, and the class 1 obesity group than in the class 2 obesity group in all variables. 3) The hamstrings/quadriceps ratio showed significant differences between groups in all variables, and the bilateral muscle strength ratio did not show any significant difference between groups. In conclusion, It was found that if the WHO obesity standard of 30 ㎏/㎡, not the Asian obesity standard of 25 ㎏/㎡, had a negative effect on the lower limb muscle strength.
