الملخص EN

The importance of the research lies in the researcher’s quest to use complex exercises in developing some biomechanical variables that constitute the basic essence of the technical performance of the back crush skill, in addition to achieving accuracy in performance by exploiting the principles and biomechanical laws and saving effort to reach the highest possible height to hit the ball, thus reaching To the best performance in the game of volleyball.

The research aims to prepare complex exercises according to some biokinetic variables for the skill of hitting the back crush in volleyball.

The researcher used the experimental method by designing a single group, as the researcher chose the research community from the young players of the Shatrah Volleyball Club in Shatrah district, which numbered (16) players.

The sample (31.25%) of the original population.

The researcher concluded that there appeared to be a development in the values of the biokinetic variables as a result of the compound exercises that were applied to the research sample.

The most important recommendations called for the use of compound exercises, as it works to develop some of the values of biokinetic variables for youth volleyball players
