The discus throwing event is one of the difficult arena and field activities in terms of technical performance, which depends on a lot of biomechanical variables that we have to research continuously to diagnose and develop through field training, and by using a multi-media computer that relies on video imaging to analyze mechanical variables and the use of a device A platform for measuring strength connected to a computer, Warka type, to extract the kinematic variables (force-time) curve to designate the researcher, coach and player to detect aspects of weakness and strength and then improve these variables. The applicants and their achievement, the percentage of the contribution of these variables to achievement, and thus it is assumed that there is a correlation between the characteristics of the curve (strength - time) with the most important biomechanical variables and the achievement of the discus throw players applicants. The researcher used the descriptive analytical approach for its suitability and the nature of the research, as the research sample included two players with the effectiveness of throwing the disc, who were chosen randomly, including (6) kinetic variables, and (14) mechanical variables were identified, and (6) variables of which represent the characteristics of the (strength) curve. Time) and (8) variables representing the most important biomechanical variables, researched based on the opinions of some experts through a questionnaire prepared for this purpose, and after presenting, analyzing and discussing the results, the researcher reached the following conclusions: A strong direct correlation appeared between (the least force recorded and each of the linear velocity of the shoulder, the linear velocity of the hip, and the linear velocity of the knee).
