Abstract EN

Volleyball is one of the group games that rely heavily on mastering basic skills as being the basis upon which to build the players, so the researcher found it necessary to talk about this subject through scientific serious attempt to find out the impact of the use of private educational exercises on according to some biochenamatic variables by using educational exercises to determine the extent of the knee joint flexion in learning the skill of receiving and serving in volleyball.

As a contribution to the development of the educational process by finding an effective way to learn and thus achieve the desired goals of the educational process.

The importance of the research was demonstrated in the correct construction of basic skills, which requires overlap in important details may be effective in the acquisition of optimum performance through educational exercises and the use of modern and innovative teaching methods.

Regarding the research problem, the researcher noted that learning reception skill is based on the virtual outer shape performance of the skill without deep understanding of the details and biochenamatic variables and use of these variables in correcting the errors associated with the performance.

The study aimed to identify the effect of assistant means and educational exercises on the values of some biochenamatic variables for the skill of reception in volleyball.

The researcher hypothesized that there were significant differences in the values of certain biochenamatic variables for the skill of reception in volleyball between the pretests and the post-tests kinetic analysis for the two groups: the experimental group and the control group and was for the favor of the experimental group .The researcher touched into the topics related to the special educational exercises, the motor analysis and technical skills in volleyball and the skills of receiving and serving.

The researcher used the experimental method and the sample for the research were the players from the specialized school for talented players in volleyball in the province of Basra, aged (12-14 years).

The researcher also touched into how to make films; have motor analysis; put special exercises; and how to make the assistant means and statistical treatments to get the search results for discussion and then to reach the conclusions, most importantly, that there was a significant difference to the values of some biochenamatic variables in the kinetic analysis of post-filming between the experimental group and the control group for the skill of reception and in favor of the experimental group.

The most important recommendations was the need to use the motor analysis and evaluation in the field of sports education as extending workers in the field of sports with fixed facts that support their decisions regarding the proper technical performance of any translation-related facts and propose appropriate solutions.
