Abstract EN

The aim of the research is to identify the values of some biomechanical variables for the throwing stage in the discus throwing event, and to identify the correlation between the values of those variables with the level of numerical achievement in discus throwing effectiveness, and the researcher hypothesized that there is a correlation relationship between the biomechanical variables under study.

For the throwing stage and achieving the digital achievement of the discus throwing effectiveness, (2) ramyin outside the research sample was used as an exploratory experiment on, and then the researcher used the final experiment in the field of experiment using (3) videotaping machines and the research sample was chosen deliberately by discus discus players from the best players Iraq clubs for applicants, number (5), and in order to obtain some biomechanical variables for the throwing stage and its relationship to achievement in the effectiveness of discus throwing for applicants(Throwing stage time, tilt tilt in preparatory section, launch angle, peripheral velocity of the aiming arm, angular velocity of the aiming arm, launch velocity, angular momentum of the aiming arm, kinetic energy of the aiming arm, launch point height, torque inertia of the aiming arm The researcher used the statistical treatments (the mean, the standard deviation, the difference coefficient, and the simple correlation coefficient r Pearson).

The statistical treatments were done by computer using the statistical bag program (SPSS).

The researcher concluded in extracting the results of the research: 1-The kinetic energy of the aiming arm is the one that achieved the highest achievement relationships in discus throwing effectiveness.2-Emphasis on the launch angle (throwing) because it has a great influence on determining the flight path of the disc.3-The researcher concluded that the kinematic variables under study have a significant impact on the discus throw distance.4-There is no significant effect of the throwing stage performance time variable on the completion distance and vice versa, that is, the lower the stage performance time the better achievement distance will be achieved.5-Increasing the rotational energy of the disk-aiming arm has a positive effect on the speed of the disc's launch and thus achieving a better completion distance
