Abstract EN

The importance of biomechanical analysis of motor skills in volleyball lies in the vertical and lateral analysis of the jump through the segmentation of the movement or skill to be analyzed and studied in order to identify the characteristics of the function and the biomechanical variables and then to clarify the positive and negative aspects of its performance.

But the common goal that players seek to achieve in the skill types is to determine the motion indicators with a high level and accuracy by investing the ideal values of the mechanical function characteristics variables.

The importance of research in the knowledge of the characteristics of the function (power - time) of the lateral vertical jump and its impact in the most important biomechanical variables of the volleyball wall of the volcano and thus provide information to help develop the skill through the knowledge of its positive and negative aspects and work to develop by taking the positive aspects and away from the negative aspects Is due to the superiority and benefit of the player himself and the team in general.

The researcher used the descriptive method in the style of interconnections which is compatible with the nature of the research problem.

The research community was identified as the players of the national volleyball team (for the skill of the wall of the repositioning of the play centers 2, 3 and 4), which are registered in the Iraqi Central Volleyball Federation 2017/2018, (5) attempts for each player so that the final number of attempts is (30) attempt to jump vertical and the same number of lateral jump.

The Statistical SPSS was used to process the data and extract the results by means of the arithmetic mean, the standard deviation, the mean, the torsion coefficient,
