The importance of research to identify the range of motion ability for attackers players who they have to get a good jump upgrade to hit the ball and this is done through tests to measure the characteristics of stability and movement so be similar to the conditions of play, as well as to identify many of the mechanical values of the straight spike stages, then work to identify the values that will happen there through a relationship with a motion ability for volleyball players to to get through them to the desired results contribute to the development of the game, where the goals Search: Identify the values of the motor run for Arbil club volleyball players as well as find a relationship between the motion ability with some mechanical variables of the straight spike of the volleyball players, either the research community were Volleyball Men players for Erbil Club consisting of (12) player either sample were (6) players after excluding setters and libro where the sample represents 50% of the community, either main experience has been implemented on the same day exploratory experiment was 07/11/2014 ,the physical tests and test the skill of the sample in internal Erbil Club Hall a testing was filming from the left side of performance and perpendicular to the performance, as the height of the center of the lens 120 cm were cameras is (3)m on the progress of the performance line ,either conclusions encompassing: motion ability of the trunk of an active and positive role in the high weight of the body center of the moment the advancement of the last touch for the land in the skill of straight spike ,as well as the motion ability of the trunk of an active and positive role in the maximum arc of the body during the flight before the moment of hitting the ball when the player spiking .

The recommendations encompassing: must pay attention to the public and private physical elements for volleyball player, including the motion ability of the trunk also must pay attention to biomechanics sides for straight spike in volleyball because they increase the efficiency of performance.
