The aim of this study was to investigate the relationship between muscular force in concentric and eccentric contractions and muscle size of quadriceps femoris. Muscle size was evaluated with total volume and cross-sectional area. The subjects were 9 normal adults (5 males and 4 females) . Their mean age was 22.6 ± 4.0. The subjects were tested concentrically or eccentrically using an isokinetic dynamometer at the angular velocity of 30 degree/sec. Total volume and cross-sectional area of quadriceps femoris were obtained from three dimensional reconstruction of MRI. The results obtained in this study were as follows; in concentric contraction high correlation between peak torque and muscle size of quadriceps femoris was recognized. In eccentric contraction, however, correlation was not so high as in concentric contraction.
