The purpose of this study was to examine the characteristics of body composition and muscular power of lower limb in water-polo players. Subjects were 14 male field-players of a top-class Japanese university team. We mesured body composition and isokinetic muscular power. Skinfolds of 14 parts were measured by means of an ultrasonic apparatus. Concentric and eccentric isokinetic muscular power of knee joint extention and flexion were measured by using KIN-COM III. The results are summarized as follows; 1) As to the mean values of height and body weight, there was no significant difference between these university players, National Team water-polo players of the Asian Games 1986, and those of Seoul Olympic Games. 2) On the estimation of the body composition of the subjects by Heath-Carter Method, the mean score indicated high Mesomorphy type. Thirteen subjects were classified as Mesomorphy type, and one subject was classified as Ectomorphy type. 3) The mean values of skinfolds of 14 parts were almost same although thats of hip and knee were slightly thickker than other parts. 4) The peak torque of concentric contraction of both of flexor and extensor significantly decreased as the angle-speed increased, but that of eccentric contraction did not change significantly. 5) The left/right ratios of both contractions were up to 10% for extensor and 7% for flexor. There was no significant diffence between the ratio of both legs. 6) The extensor/flexor ratios of both contraction showed similar tendency in both legs. The ratio in concentric contraction increased 7-10% as the angle-speed increased. The ratio in eccentric contraction did not change.
