The effectiveness of discus throwing is one of the activities that require special physical abilities and mechanical conditions aimed at achieving the best horizontal distance for this competition, and performance is associated with achieving the highest instantaneous strength and rapid strength in the muscles of the working body, especially the trunk, legs and arm shooting, and the researchers believe that the amounts of these forces can give a good indication of what is supposed to be achieved from the integration of skill performance, which aims to achieve the highest speed at the end of the arm shooting, so the control of the values of these The forces, especially the two legs through the device (Dyna foot) can help the researcher to make the right decision if these forces are optimally exploited to achieve integration of performance, as well as monitoring the amount of pressure and force affecting the weight of the thrust and the extent to which these variables are used to identify errors and develop solutions to improve the exertion of the appropriate special force for them, and the researchers assumed that there is a significant correlation between the momentary force exerted by the two legs when placing the throw with the biomechanical variables of the throwing performance, The researchers used the descriptive analytical approach to process data and information related to the nature of the problem. The researchers chose a sample of Iraqi heroes with a number (4) elite disc shooters, and the researcher concluded that there is a significant correlation between the momentary force and the pressure exerted by the feet and the momentary force in the trunk and arms with some biomechanical variables to perform in the discus throw, as well as between the rapid strength of the legs with the variables of the disc launch. |
