| Abstract: | In the technical motions of javelin_throwing, a number of velocity factors might affect the athlet's results, and one of them is the velocity that the apparatus acquires at the final strength_exerting moment, which is estimated to account for 70_80% of the javelin off_hand velocity. Therefore, to improve the score it is of great significance to study the variables of velocity in the final span of strength_exerting. The paper makes a comprehensive and analytic study of this issue by retrieving literature, conducting interviews with experts and Using mathematical statistics. The author holds that any change in the technical indications of the four velocity factors can result fluctuations of the athlete's score. |
