Abstract
The research aims to identify the relationship between the explosive power of the striking arm to the accuracy of the overhand serve among Qaraqosh Sports Club volleyball players.The researchers hypothesized that there were significant differences between the explosive power of the striking arm and the accuracy of the overhand among Qaraqosh Sports Club players.The researchers adopted the descriptive approach for its suitability and the nature of the research , and the research community was represented by the Qaraqosh Sports Club advanced players of volleyball for the sports season (2018-2019) , who numbered (20) players. The research sample included (14) players. The variables were homogeneous among them (height, mass, and chronological age). The researchers used questionnaire forms, tests, standards, sources, and scientific references as tools to achieve the research goal. A test of the explosive power of the arms and a test of the accuracy of the performance of the overhand serve skill in volleyball to suit the research sample , for the period from 4/2/2018 to 4/4/2018, and the SPSS statistical package was used to process the data statistically. The researchers concluded that the explosive power of the arms positively affects the accuracy of performing the skill of overhand serve in volleyball through the presence of significant relationships between them. The researchers recommended emphasizing the presence of training programs that are concerned with developing the explosive power of the arms within the physical, skill and tactical preparation programs for volleyball players , because this has a significant impact on the level of basic skills in the game, especially the serve.
