Kinematic Contribution to Javelin Velocity at Different Run-Up Velocities in Male Athletes

In the javelin throw training, many throwers improve their throwing technique by from a slower run-up velocity than in competitions. However, whether acquisition of is same as full unclear. The purpose this study was to clarify differences contribution each movement caused changes within an individual. Twelve collegiate male were included study. Throwers performed two types throws: one-cross (Cross) and (Run). coordinates reflective markers attached thrower’s body recorded using optical motion capture system. percentage joint calculated compared between Cross Run. had lower trunk forward lean upward velocities On other hand, higher counter-clockwise rotation These results suggest that individual, also changes.
