The purpose of this study was investigated the muscle structural on limbs in wrestlers. Subject were 5 light weight groups (LG) and 8 middle weight groups (MG) and 4 heavy weight groups (HG)．The muscle mass of the whole body, trunk, upper limbs and lower limbs were measured using the body impedance analysis method. The muscle thickness was measured by B-mode ultrasonic method. Significant differences of muscle mass between LG, MG and HG were obtained. And also, there are not significant differences ratio of each muscle mass to whole body muscle volume. Muscle thickness was observed differences among three groups. Significant correlation coefficients were observed in the relationship between body weight and whole body, trunk and lower limb in all groups. Body weight was significantly correlated to the upper limb muscle thickness in all subjects. Significantly correlation coefficients were observed in relation between each upper limb muscle thickness and body weight in all subjects. And also significant correlation was observed in relation between knee extensor and body weight in all subjects and HG. Also, significant correlation with MG and all subjects in relationship between muscle thickness knee flexor and body weight. For muscle thickness lower leg, a significant correlation was observed all subject to dorsi flexion, plantar flexion and body weight. From these results, muscle thickness of the lower limbs showed large value in wrestler of heavy weight. Relationship of muscle mass and body weight, in relation to the muscle thickness and weight, skeletal muscle mass of each part is considered to be affected by the increase in body weight, the Relationship observed between the skeletal muscle mass and body weight was suggested that different in the upper limbs and lower limbs and trunk.
