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.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
