This research aimed to determine the role of some mechanical variables for the first and second place at the Olympic level and world champions, it can be said that there is a preference for some mechanical variables for the achievement of the high jump, and the research sample was the Arab champions in the advanced category of high jump in the Arab championship on 6/22/2021-16 in Tunisia (Rades Stadium). I used the descriptive method because it suits the nature of the research issue. He used five cameras in different directions and analyzed the attempt (2.16) meters for each vaulter and compared the best vaulters (Hussein Falah and Hamdi Ali) in the mechanical variables of the activity of the three free limbs and compared the reason for the success of the jump, he used five cameras installed on a tripod surrounding the player from all directions and all cameras are at the speed of (120) images / second to fit it with the speed of performance. He reached conclusions where the player (Hussein Falah) relies more on physical abilities than technique, if the technique had been corrected, he would have been able to take advantage of the lost height above the crossbar and break the Iraqi record. The player (Hamdi Ali) relies on technique and physical measurements that give an advantage to the player Hamdi in crossing the bar on the first attempt. We can recommend developing the technique to a height higher than 2.19, which was successfully jumped by Hussein Falah to identify and improve weaknesses, whether physical or skill, and conduct tests at intervals and provide effective specialized coaches who are professionals in the high jump.
