The purpose of the study was to compare selected kinematic variables between the female medalists and a Korean female javelin thrower at the IAAF World Championships, Daegu 2011. Three medalists and one Korean javelin thrower that participated in the Championships were videotaped using three high-speed cameras (300 frames/s, EX-F1 Exilim, Casio, Japan). This study identified the performance differences between the two groups. The results showed that the Korean female javelin thrower (KFJT) clearly had a greater delivery phase time than the female medalists. In order to throw farther, a thrower must exert a greater force to accelerate their body in a short time. This study also found that the release velocity of the KFJT was lower than that of the female medalists. The KFJT showed evidence of using her extremities differently to achieve the maximum release velocity. When comparing the inclination angle of the trunk across javelin throwers, the lowest value was recorded in the KFJT. Because the trunk position at release plays a significant role in determining the release height and release velocity, the KFJT should not rely on her upper extremities to achieve as high a release velocity as possible.
