This study investigates a new technical index in the javelin throw by analysis of the javelin throwing motion. Two skilled throwers, one semi-skilled thrower and one unskilled thrower were the subjects in this study. Each throw phases was recorded with two VTR cameras. The VTR films were digitized and the various biomechanical data were obtained through a personal computer system. This new index will give a useful skill advice for throwers to improve their records. Many papers have described this theme. A rapid decrease in the waist (center of gravity) during the throwing motion is noted in subjects who hold good records. This is confirmed in this study also. Therefore, in order to treat this phenomenon quantitatively, a new index : decreasing velocity rate of the waist (center of gravity), was calculated and an important significance I found that the new index possesses.
