Abstract:

The effectiveness of javelin throwing is one of the competitions with complex technical performance and requires special physical and motor abilities Which should be performance at the highest level of control of their biomechanical variables so the researchers used the analytical descriptive method, and the researchers chose the research sample in a deliberate manner, and consisted of the champion of Iraq for the effectiveness of throwing the spear for the year (2019) m and the second place in the same tournament, The researchers used to shoot the final stage of the shooting process in addition to the first section of AlRamah flight for the research sample during the main race on Friday, 8/3/2019 at 3:00 pm. The researchers used one Panasonic camera with 120 speed / Triangular, proved by ja (1.30) meters, and is located from the middle of the width of the field of approach to a distance of (6.30) meters, to be vertical on the middle and at the height is vertical to the bearing of the shaft and the javelin is recorded, and the mechanical analysis on the attempted achievement Better and The authors reached several conclusions, including several conclusions and The high starting speed of the hero of Iraq is the main variable that achieved the greatest distance and There were a number of recommendations. The most important of these was the attention to the height of the starting point of the hero of Iraq if he had achieved a point of departure (2.35) m, the same value achieved by Rami Karar Raad Mohi to the height of the starting point of the spear had a distance of throw up to (75.34) m.
