الملخص EN

The problem of research is that there is a decline in the speed and accuracy of the performance of the skill spike front (country) volleyball of Kirkuk university team because of the lack of accurate understanding of the correct performance of this skill and the lack of information that deal with the particulars and details of performance, thus showing weakness in performance and not subject players to scientific observation technical video and the process of motor analysis is in itself a problem and this has prompted researchers to study this problem.

the study aims at: recognize the relationship between some of the variables biokenmatics and the relationship between the accuracy of the performance of the skill spike front (country) volleyball of Kirkuk university team, the researchers used the descriptive approach in the style of associative relationships.

the sample consisted of (6) players from the volleyball Kirkuk university team for the academic year 2018-2019.

the technical observation was used by video imaging using a 50-picture/ second-generation sport hero.

the players were analyzed using kinovea.

the results were statistically treated using (arithmetic mean, standard deviation, pearson correlation coefficient ) and the researchers concluded: -the angular velocity of the trunk has a large role in the technical performance of the skill of beating the spike front(country) volleyball of Kirkuk university team.

-the higher the angular velocity of the trunk, the higher the velocity oceanic and thus increase the speed of the ball in the performance of the skill of beating spike front(country) volleyball.
