الملخص EN

The research aims to identify: - The relationship between the persistence of attention with both the performance and accuracy of the skill of the Blooking in volleyball.

- The relationship between the Speed of kinetic response with both the performance and accuracy of the skill of the Blooking in volleyball.

The researcher used the descriptive approach with correlation style to suit the nature of the research.

The research sample consisted of volleyball players of the category of applicants to (8) clubs of the Kurdistan Region participating in the co-existence championship, which was established Akad Sports Club for the season (2016-2017) , The number of(89) Represent(87.25%) of the original research community.

The research sample was tested by (4) mental, physical and skill tests as means of gathering information to achieve the objectives of the research.

So to handling results, the researcher used the following statistical means : (Percentage, mean, standard deviation, Sprain coefficient, simple Pearson's correlation coefficient).

Conclusions: -There is a significant correlation between the persistence of attention with both the performance and accuracy of the skill of blooking in volleyball sample of the research.

- There is a significant correlation between the time of the Speed of kinetic response and the accuracy of the barrier of blooking in volleyball of the sample of the research.

-There is a non significant correlation between the time of the Speed of kinetic response and the performance of blooking in volleyball resistance the sample of the research.

Recommendations: - The need to focus on the application of scientific principles and foundations to develop the stability of attention and of the Speed of kinetic response in line with the requirements of performance and accuracy of the skill of blooking in volleyball.

- The trainers must be sure to give importance to their training in the stability of attention according to the specific performance of each skill of rejection in the ball in volleyball.

- The need to confirm the speed of kinetic response that has a direct impact on the performance of skilled volleyball player according to their specializations.
