其他摘要：The measurements of muscle strength have been made on 126 college sports-club males belonging to seven events. The muscle groups subjected were elbow flexors "elbow extensors, knee flexors" and knee extensors. By uinsg a spring-balance dynamometer the isometric strength has been determined at right angle of the elbow or the knee joint. The results are summerized as follows. 1) It can generally be said that (i) the ratios of flexor strength vs. extensor strength are 3 : 2 in the elbow and 1 : 3 in the knee, and that (ii) the right limb muscles are consistently more (1-2kg) powerful than the left limb"s. 2) Top rank in the leg strength has been occupied by the field athletes of the track and field, and followed by Judo-ka. In the arm strength, however, the ranks of those two events reversed. 3) Sprinters ranked third in all the strength scores. Men of the ball games (handball, volleyball, soccer.) and the gymnastics took low ranks either in the arm or in the leg strength. 4) Gymnasts showed comparatively high values in strength/body weight ratio as well as sprinters, whereas Judo.ka showed low values, in paticular, of the leg strength/weight. 5) In the case of lower limb, the strength/limb girth ratios were arranged in the same order as the leg strength scores of the events, but not the case in arm strength/girth ratios being high in sprinters and handballers.
