여자 창던지기 동작의 Kinemitc 적 요인 분석 = Kinematical Analysis of Woman Javelin Throwing

다국어 초록 (Multilingual Abstract)

The purpose of the study was to analysis in javelin. Three athletes in the level of national representative were participated in this study. The study analyzed kinematic variables(lead foot and releasing javelin) through 3-D analysis and obtained the following results. 1. During withdrawal, it is important to maintain of running velocity. 2. When the left foot was landed in angle of upper body, three athletes maintained relatively appropriate angle. When releasing, S3 was not good upper body(95˚) than other subjects. It caused increase of release velocity to be prevented. 3. In a left knee angle of three subjects, when landing, 53 angle was too small. This results from decrease in running velocity due to too bending knee. 4. In a throwing angle, 53 was too big in posture angle and too small in release angle. 5. Compared with world top-athletes, release velocity was Bow, and specially in vertical factor velocity showed high difference. This results associate with movement of the center of body and influence of knee. According to the above conclusion, when the athletic leaders cauch athletes, they should focus on maintaining knee angle, upper body and hip angle in a previous stage of release and throwing angle, throwing height, throwing velocity in a release stage.
