This study was a kinematics analysis of the javelin throwing from the four men's throwers. U thrower (Best record 78.32m-this time 69.54m), Si thrower (Best record 71.96m-this time 65.34m), S thrower (Best record 64.58 nvthis time 55.67m) and K thrower (Best record 58.18m-this time 54.18 m) were the subject in this study. Video-taped, using two 30 fps digital-camera. The VTR films digitized and the various biomechanical data obtained through a personal computer system. It is most important that the approach velocity is transferred effectively to the javelin velocity through the throwing motion. Transferring rate from Approach momentum to javelin movement. The study results were a as follow U thrower (3.35%), Si thrower (3.50%), S thrower (2.86%), K thrower (3.49%). Transferring rate and especially flight distance were not related. But, this index may be used only within the same individual.
