<![CDATA[The importance of research came in the fact of knowing the contribution of each of the physical and biomechanical variables to the level of performance of the front strikes, as well as seeking to develop some physical and mechanical capabilities of the accuracy of the performance of the front ground strike to improve the performance of the research sample for the junior group (14-16) years. As for the research problem: Despite the development of the tennis game in Iraq, it suffers from difficulties that impede the course of its development, and through the experience of the two field researchers, the research problem was identified and the previous studies and follow-up of the tennis tournaments for age groups were identified. Performing optimally and among these requirements are special physical abilities and biomechanical conditions that must be characterized by the skills of tennis, especially the forehand skill. Accordingly, the two researchers found the necessity to conduct tests on the physical abilities of tennis players, and to conduct a kinematic analysis to identify the biomechanical conditions of the striking and forehand skills, especially for tennis players aged (14-16) years, considering that knowing these variables for these ages can lead us to the correct path of skill performance and the need for Knowing the precise contribution of each variable to the performance to be later emphasized on these variables that contribute more accurately to performance and development, and to reinforce the other variables less contributing to training and development.]]>
