Correcting the accuracy of performance and developing some biomechanical indicators through visual monitoring and feedback of hammer throwing to applicants

Abstract

  Visual observation and feedback with a sense of movement are the basis for the picture of correct performance in the hammer throw. This leads the thrower to control the movements that occur and allows him to review other aspects of movement so that the feedback information is consistent with the picture of motor performance, which allows the thrower to perform better in competition situations. The researchers wanted to find solutions to this problem through visual monitoring of the pitcher’s performance and review by the player and coach to identify the exact defect in performance and avoid it through repeated practices accompanied by this type of feedback. The research may require measuring some mechanical variables to demonstrate the effectiveness of using feedback through repeated and immediate visual review in correcting them. The research was applied to a sample of advanced Iraqi hammer throwers three times a week for a period of (7) weeks. Among the results of the research was the development of the instantaneous momentum at the moment of throwing, and the development of The resulting acceleration (vertical and tangential) at the moment the hammer is fired, the differences in the momentum between the throwing position and the final throw decrease, and the final achievement improves.
