Measurement of leg strength has been an unexplored field of research in Japan. The author devised a leg dynamometer which was so designed as to enable to adjust the angle of knee joint in the sitting posture according to subject's leg length. It became possible to measure the maximum strength of leg extension accurately by this apparatus. It follows from the results obtained on the students of Yamanashi University that Leg strength is greater than either grip strength of both hands together or back lift. 2) There are rather greater individual differences and standard deviations. 3) Strength of right leg tends to be greater than that of the left.
