The difference research methods in the study of a specific variable but is intended to delve into all aspects of the process that can be influential factor in the development of skill or variable on the order adjust effects related and keep what does not affect the side skill to the possibility of studying skill form of scientific and development.

And our research is one of this research that it deems study the accuracy of the transmission performance according to the determination of overwhelming palaces of the arm striking because of its significant impact on the speed of motor performance differences of the striking arm of the ball, including reflected the result on the accuracy of the transmission performance overwhelming.

The objective of this research is to identify the relationship between the moment of inertia of the striking arm and the accuracy of the transmission performance overwhelming, either impose search was a significant correlation between the moment of inertia of the striking arm and accuracy transmitter overwhelming.

The researchers used a descriptive approach to suite it with the nature of the proceedings, has included sample (10) students of the fourth stage, which represent the research community's (100) students.

After obtaining the data were processed through SPSS statistical program to get the results, compiled in tables for discussion and through what progress has been access to the most important conclusions: 1 - The use of the arm in the performance of skill required properly leads to increase torque shortcomings which increases the speed of movement of the arm strike and thereby increasing the accuracy of the performance of the skill.

2 - increase the moment of inertia of the arm strike leads to an increase in the release rate of the ball and precision in directing.

The main recommendations are: 1 - the need to correct the wrong performance and emphasis on it to get to the precision required in the performance.

2 - the need to conduct similar studies using moments palaces other parts of the body and other volleyball skills.
