The purpose of this study was compared the effect of BMI on isokinetic knee muscular contraction at different speeds in middle school students. Twenty four students divided into normal group BMI ≤ 24.9kg/ m², overweight group BMI 25.0 - 29.90kg/m², and obesity group BMI ≥ 30.0kg/m² assessed by a body composition analysis equipment(Inbody 720, Biospace, Korea) which measured the knee joint in isokinetics protocol 30°/sec, 60°/sec, 180°/sec, and 240°/sec with muscle contraction in con/con cycle used isokinetic dynamometer(Humac Norm testing & Rehabilitation System ,Cybex, USA). Peak torque of extensor & flexor(Nm) showed the significant difference among each group that is obesity, overweight, and normal group in an orderly fashion(p<.05, p<.01). Peak torque of %body weight showed normal, overweight, and obesity group in an orderly fashion, but the significant difference between normal and obesity group(p<.01). Also, the significant difference among different speeds showed from 30°/sec, 60°/sec to 180°/sec, and 240°/sec. Right & Left ratio(%) showed the significant difference among normal and obesity, overweight group in speeds 30° /sec and 180°/sec(p<.05). Hamstrings/Quadriceps ratio(%) showed the significant difference between 180°/ sec, 240°/sec and 30°/sec, 60°/sec(p<.05). These results suggest that BMI was associated with isokinetic knee muscular contraction that normal group showed significantly higher values in peak torque of %body weight of isokinetic strength of knee and Hamstrings/Quadriceps ratio showed higher values in high speeds.
