女子 滄 던지기 選手의 生體力學的 分析 = Biomechanical Analysis of Javeli-n Throwers

다국어 초록 (Multilingual Abstract)

A two-dimensional film analysis was performed on three women finalists in the Javelin throw of the Los Angeles Olympic Games of 1984 and one woman finalists in the Javelin throw of the Seoul Asian Games 1986.
In addition to the great inter individual variation in the measured kinematic and kinetic parameters, the results indicated, despite great variation in throwing distance in group(55.88m - 69.56m) the reaeare velocities were in relatively small range(20.73m ×??,-23.62m×??). High impact loadiong was specific to the last on the ground. It was characterized by a short duration(0.032,) and high velocity knee flexion(12.66±2.66±2.11 and 12.27±3.81 rad × S¹, respevtively,for women). The respective knee extension velocitities averaged 5.80±2.00 and 7.60±5.17 rad × S¹, Despite the fact that a small number of analyzed worlr class throws revealed only some biomechanical differences between good and poored performance, the result can be used to identify some new criteria for successful performance in Javein throw.
