The research aim to study the relationship between some bio kinetic variables and the throwing distance in the hammer. Methods The researcher used the descriptive approach using three-dimensional mechanical analysis (3D) based on the technique of video imaging and kinematic analysis using the Simi Motion program for its relevance to the nature of the study. The research sample was chosen by an intentional method, namely Mustafa Muhammad Hisham El-Gamal, player for Al-Ahly Club and the Egyptian National Athletics Team, and player Islam Massad Abu Saree (age: 29.50 ± 80. years, height 188.00 ± 62. Cm, weight 120.05 ± 11. Kg, training age 14.50 ± 19). The appropriate way, where the imaging cameras "Go pro" camera type of the Simi Motion Analyzer unit are equipped as it is equipped with a battery, and a speed of 250 cadres / s, as the work of the three cameras was confirmed to coincide with each other, and the calibration box was placed 1 m x 1 m X 1 m in the middle of the throwing circle. Biomechanical measurement and analysis was done using SIMI 3D motion analyses. Results: The hammer speed increased from rotation. To another, and this in turn leads to a decrease in some biochemical variables, the momentum and force in the general center of gravity of the body and some of its connections. recommends The momentum and velocity) requires in its development to establish a comprehensive movement of various and interrelated exercises such as lifting movements with weights, thrust and stability, in the different biomechanical positions that match the performance moments of the hammer
