The research aims to identify the effect of motor coordination exercises in developing the accuracy of defensive skills in volleyball for players of Al-Habbaniyah Sports Club, as well as identifying the relationship between the accuracy of defensive skills in volleyball and the speed of motor response. The researchers assumed that there is a positive effect of motor coordination exercises in developing the accuracy of defensive skills in volleyball for players of Al-Habbaniyah Sports Club., as well as the presence of a significant relationship between the accuracy of defensive skills in volleyball and the speed of motor response. The researchers used the experimental method and designed two equivalent experimental and control groups. The research sample was represented by the players of the Habbaniyah Sports Club, numbering (12) players. It has been applied. Exercises motor coordination Three training units in the week, with a total of (30) training units, were distributed over (10) weeks. The training unit time is (90) minutes, and implemented than experience Monday Agree (29/4/2024), and until the day of Saturday Agree (6/7/2024). After completing the experiment and obtaining the results, the researchers concluded that: motor coordination exercises have had a significant impact. Positive in development Skills accuracy Defensive With volleyball for the players of Habbaniyah Sports Club, and There are significant correlations between accuracy Skills Defensive With volleyball The speed of motor response of the experimental and control research groups varied in proportions. Accordingly, the researchers recommend that the necessity of using motor coordination exercises to develop defensive skills in volleyball, as well as conduct research. In motor coordination exercises to develop offensive skills in volleyball.
