and exercises with weights are one of the modern training methods that aim to break the state of boredom, and increase strength and shocks for the muscle.

given the importance of the explosive ability of the arms that the researcher tried to study because it is the best way to achieve the goal, and therefore, the importance of the research lies in the effect of exercises with weights in developing the explosive power of the arms and the accuracy of the crushing beating of volleyball, and the aim of the research is to prepare exercises with weights to develop the explosive ability of the arms and accuracy the skill of crushing hitting in volleyball, and identifying the effect of training with weights in developing the explosive ability of the arms and the accuracy of performance of the skill of crushing hitting in volleyball among the members of the research sample, and identifying differences between the experimental and control groups in the explosive ability of the arms and the accuracy of performance in volleyball for the post-tests.

as for the hypothesis of the research, it included the presence of statistically significant differences between the experimental and control groups in the variables of the explosive power of the arms and the accuracy of the skill of crushing hitting with volleyball in favor of the experimental group, and the presence of statistically significant differences between the pre and post tests in the variables of the explosive power of the arms and the accuracy of the skill of crushing hitting with volleyball in favor of the test after, the researcher used the experimental method by designing (the two equal groups with a pre and post test) for its suitability to the nature of the research and its problem, and it represents the research community of al-Muqdadiya volleyball club players for the season (2020-2021), which are (18) players.
