The purpose of this study was to examine isokinetic strength in throwers. The subjects were nine throwers with four put-shotters, four discus-throwers and a javelin-thrower. The method of conducting the experiment was measuring the peak torque at the knee extension, the elbow extension, the shoulder abduction and the shoulder horizontal adduction in four specific speeds (60,180,300 and 500 deg./sec.) with the MERAC system. (Universal Gym Equipment, Inc., ) The results were as follows : 1) When the speed of movement increased, the peak torque at knee and elbow extension decreased. This was not, however, not identified in other actions 2) When hte speed of movement increased, the difference in peak torque at knee and elbow extension of different subjects decreased. 3) Regardless of the speed of movement of the elbow extension, the peak torque of the put-shotters and the javelin-thrower was larger than in discus-throwers.
