|b -The results taken from Movement analysis in the domain of biomechanics present one of principal basis and criteria from which we can form athletes in high levels. this is thanks to the précised and significant kinematical and kinetical variables that determine the trajectory and the level of Movement of different skills. -this is why our study wants to show the mechanical variables that determine the trajectory of speed in world champion (2009) in athletism in Berlin, because the athlete – Usain. bolt – succeeded to obtain a new world record (9.58 s) and he obtained another time an Olympic record in London (2012) 9.63s that he recorded in Pekin (2008) (9.69s) in 100m speed. This performance pushes the specialists in athletism to consider it as significant model in kinematical and kinetcal variables in forming athletes in scientific basis. - The methodology of research is based on the use of different logical of Movement analysis( Logiciel Video Performer, Logical Tempro, Logical Video to Picture ……),to get the value and percentage of the variables of research. And using also the mechanical principals and mathematical equation. - The final results of the research concluded the following: The exact departure is one of principal factors of success in speed competitions The athlete (Asafa.Pawoul)obtained the best departure in - 0.134 s – The weak starting speed for (Usain.bolt) compared to (T.G/A.P). The success of (U.P) to other athletes in number of steps of 40.92 steps. (Tyson. Gay) had the best frequency in steps of 4.81S/s. The athlete (Usain.bolt) has the amplitude of -2.44m- . The (Usain.bolt) has the best maximal speed of 12.42m/s
