Abstract
The purpose of this study was to investigate the relationship between distance and factors of javelin in korean male``s javelin throwing. To accomplish this purpose, the analyzed trail selected total 29 trails (subjects 9) recorded more than 65 m in the 93rd National Sports Festival. The Kwon3D 3.1 version was used to obtain the three dimensional coordinates about the top, grip, end of javelin. And the kinematic data such as projection factors and direction angle of javelin calculated using Matlab2009a program. The statical analysis on the records (n=29) were used to Pearson``s product moment correlation coefficient. There was a statistically positive relationship between the records and horizontal velocity (r=.866, ρ<.01), height (r=.541, ρ<.001), height rate (r=.373, ρ<.05) and horizontal displacement of javelin (r=.749, ρ<.01), but the medial/lateral velocity showed a negative relationship to r=-.663 (ρ<.01). The attack and yaw angle showed not a significant relationship between the records, but the medial-lateral tilt (E1:r =-.557 [p<.01)] E2:r=-.629 [ρ<.01], E3:r=-.528 [ρ<.01]) and attitude angle (E2:r=-.629 [ρ<.01], E3:r=-.619 [ρ<.01]) of javelin showed a negative relationship between the records, as well as the projection angle of javelin (r=-.419, ρ<.05) showed a negative relationship between the records.
