Abstract: In the researcher's pursuit of the effectiveness of using compound exercises represented by muscular work angles exercises and similar to skill performance in developing some biomechanical variables (kinematics and kinetic) that constitute the basic essence of the technical performance of the skill of the Qatari back crushing skill, in addition to the exercises of kinetic abilities represented (compatibility and agility) in achieving and reaching accuracy in performance by exploiting the principles, foundations, mechanical laws, and economy with effort to reach the highest possible height from the back area to hit the ball over the opponent's block wall and land in the front area and achieve a valuable point and thus reach the best performance in the offensive skill from behind the front line volleyball. As for research problem In that there is a clear weakness in the performance of the players for this type of crushing beating in most teams, specifically the stage of linking between the maximum strength of the legs and the explosive strength of the arms, and this requires the player to possess a high degree of compatibility and agility, as well as the distance between the implementation area and the areas of accuracy, and this causes the player to unalign correct posture during the skill sections, which causes a loss of balance, and this increases the amount of during the approaching phase, causing an incorrect momentary stop effort expended that is not commensurate with the required speed. As for research aim Preparing complex exercises according to some biomechanical, physical and kinetic variables for the skill of the accuracy of the smash hit, the diagonal rear facing of the volleyball. As for hypothesis of Research: There are statistically significant differences in the values of some biomechanical, physical and kinetic variables in the tribal and post tests of the skill of crushing hitting the back facing volleyball in favor of the post tests of the experimental group. The researcher used the experimental method by designing the experimental and control groups for a period of (8) weeks and each week (3) training units. The back smash players numbered (14) players (7) players for each group, and the sample percentage was (77,77 %) from the original population, while (4) players were chosen for the exploratory experiment and were excluded in the main experiment. 1- 5 Researcher's Conclusions: It appeared that there is a development in the values of biomechanical, physical and kinetic variables as a result of the compound exercises that you applied to the research sample. As for recommendations of researcher The researcher recommends the use of compound exercises, as it works to develop some of the values of biomechanical, physical and kinetic variables for young volleyball players.
