This research aim to use of maxmal power exercises to development some bio mechanics variables for hammer throw for competitors. 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, namely Mustafa El-Gamal, player for Al-Ahly Club, 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: Maximum power makes a significant contribution to the performance of the hammer throw, especially the moment of throwing. The maximum power is approximately equal to 1/6 of the value that could be achieved if the individual could exert the maximum force and the maximum speed.. Recommendations: Coaches must make the right choice of maximum power exercises associated with hammer toss performance, due to its effective impact on performance development
