The purpose of this study was to investigate the relationship between javelin throw distance and factors affecting throw distance by world class male and female javelin throwers. This involved analysis of results from a total of 34 attempts by top 12 javelin throwing athletes (6 males and 6 females) participating in the 2019 Mokpo Throwing Competition. To achieve the research objectives, three high-speed cameras were used during the competition and analyzed using a three-dimensional analysis program (Kwon3D 3.1). The results show that males had a negative correlation with the horizontal velocity from the time of left foot landing (LC) to the time of right foot landing (RC) during cross-step (r= -.726, p=.01. Conversely, for women, the foot center distance, velocity, and LC-RC value before projection were positively correlated (r=.717, p=.001) appeared. The maximum angle and record of the knee are negatively correlated only in the female record (r= -.532, p=.028). Javelin posture angle and attack angle had negative correlation with record (r= -.489, p=.046; r= -.509, p=.037). For male athletes, the horizontal velocity before projection requires a maximum velocity that does not affect their posture during projection; for female athletes, the higher the velocity, the higher the record, and the higher javelin’s posture angle and attack angle. These results show there was a difference in the record factors between male and female athletes in the javelin throwing record, and guidance considering gender and individual characteristics is required.
