The neglect of muscle training in the shoulder joint causes joint injury and recurrence of the joint, resulting in permanent weakness in the working muscles, which causes weakness in the performance of the skill, and plays the type of special training of these muscles a role in restoring the ability of these muscles to work, The study aimed at identifying the level of electrical activity of some of the working muscles of the shoulder joint in EMG during the performance of the overwhelming beating of the Qatari sample of the research.

Drills (Physical-technical) of the muscles of the shoulder joint, and thus identify the effect of special exercises (physical - technical) to develop the strength of some muscles and the accuracy of the beating skill overwhelming in the research sample.

The researcher used the experimental method on a sample of the players who suffered from repeated injuries, and the number of (13) players representing the community of the total search of the players of the clubs of Baghdad, and after having been the tribal tests in the accuracy of beating the Qatari and electric muscle, Post-test.

And then the results were collected and processed statistically and the researcher found that there are differences of statistical significance between the tests of tribal and remote and in favor of the post-test of the sample of research in the indicators of electrical activity of some muscles to the accuracy of the beating skill overwhelming.

Therefore, the researcher recommends the need to pay attention to the performance skill, especially the skill of beating overwhelming as it achieves a point directly, through the diversification of special exercises with similar motor paths similar to skill, and the need for attention to electrical activity because of its impact on the accuracy of the skill of beating overwhelming.
