      다국어 초록 (Multilingual Abstract)

      This study is to analyze the effect of the kinematical factors of man and woman javelin throwers. 6 subjects in this study took part in current high ranked in univer sity competitor. Two S-VHS video cameras set in 60frames/sec were used for recording from the landing of last step to the landing of reverse motion in javelin throw. After filming and digitizing when the javelins were thrown, the Direct Linear Transformation(DLT) technique was employed to obtain 3-D position coordinates (Abdel-Aziz & Kararah,1971), a cubic spline function was used for smoothing and differentiation and the time, displacement, velocity and angle variables were calculated.
      And the following conclusions were drawn;
      1.The man players showed the shorter duration from the landing of last step in approach to landing of reverse motion than woman players, especially, in phase1 from landing of last step to release.
      2.In the COG at the last step before release showed similar pattern, but in the stride width change showed shorter than woman players and in the reverse motion after release showed longer.
      3.In upper arm horizontal velocity, the man players showed more rapidly than woman players. Therefore, the man showed difference woman in record.
      4.In angle variables, the angle of trunk in release event done a inclined condition about 10 degree. especially, the angle of shoulder and the elbow showed to flexion in release event all.
      5.For effective release motion, the woman players should increase the muscle power and agility as large as possible, and lean the body to vertical, increase. The thigh and shank should be increased the angular velocity about hip and knee joint with propelling toward COG at right foot landing ready to reverse motion.
