This study aims to compare isokinetic muscle strength of quadriceps femoris and hamstring muscles, major muscles around knee joints, and examine their differences in normal people in accordance with their body mass index. A total of 102 normal subjects in their 20s were divided into a normal group and an overweight and obesity group based on the WHO BMI classifications for Asians and their body compositions were measured from January 3 to August 31 2011 using a body composition analyzer. Absolute muscle strength, bilateral muscle strength deficit, and flexor/extensor strength ratio, and muscle strength relative to body weight of the quadriceps and hamstring muscles were measured with isokinetic equipment and compared. Absolute muscle strength of knee-extensors and knee-flexors was significant (p<.05) but relative muscle strength, bilateral muscle strength deficit, and flexor/extensor strength ratio were not significant between the ordinary group and the overweight and obesity group, both of which consisted of males and females in their 20s, in accordance with their body mass indexes at an angular velocity of 60 °/sec Absolute isokinetic strength of quadriceps femoris and hamstring muscles had positive relation with increase in body mass index in males and females in their 20s.
