Researchers and specialists in the field of sports injuries and prevention on the one hand, and biomechanics on the other hand, seek to find the best ways and means to raise the level and abilities of athletes according to scientific foundations, especially when there is an urgent need to research one of the topics that athletes in racket sports events (tennis) have long suffered from. As well as athletics events (javelin throwing), which are injuries to the tennis elbow. The research aimed to prepare special preventive-mechanical exercises (Tennis Elbow) to improve the range of motion and strength of the lateral humerus muscles among tennis players and advanced javelin throwers, and to identify the effect of these exercises in both groups alike and to compare (percentage of development) for all variables in the post-tests. – Dimensional. The problem of the research centered on the importance of protecting players from the common injuries to which they are exposed to players in racket sports events (tennis), as well as players in athletics events (javelin throwers), who always resemble the type of potential injury, which is (Tennis Elbow), due to their excessive use of muscles and tendons when serving and when serving. Throwing according to his specialty. Therefore, the researchers decided to try a combination of strength-specific exercises (pullover, bungee under a hammer, incline bungee, pull-up), as well as exercises for flexibility (with rubber ropes), and finally exercises for (medicine balls). The researchers used the experimental method with two experimental groups for the variables under study. The research sample included two groups of elite athletes. The first group included (6) advanced tennis players, while the second group included (6) advanced javelin throwers. Field tests related to strength and flexibility (Tennis Elbow) were conducted for both groups, after which the training program was implemented, which included (12) training units for a period of eight weeks at a rate of two preventive training units per week targeting the main part of the unit. The researchers concluded several conclusions, the most important of which is that the prepared exercises had a clear effect on the sample members for both groups through the significance of the significant differences between the pre- and post-tests. In light of the results, the researchers recommended the necessity of applying these exercises, which were prepared according to mechanical principles, with other activities that would prevent possible injuries in the body. the future.
