In order to study the claracteristics of a Judo athlete's muscle strength, regulated measurements of both leg/knee extension and leg/knee flexion strength were taken with use of a Isokinetic Muscle Contraction Weight Machine and then compared and studied for each weight category. The following conclusions can be deduced from the consequent results. 1) The value of peak torque decreases in proportion to an increase in the speed of movement. 2) The value of power increases in proportion to an increase in the speed of movement. 3) The value of peak torque together with power increases with the increase in weight ategory (light to heavy). 4) If one looks at te different values of peak torque per weight as well as power per weight within each weight category, the +95kg group shows a significantly smaller speak torque and power value than any other weight category. No significant difference could be observed through out the different weight categories when peak torque and power values of the lean body mass (LBM) of each weigth group were taken.
