Objective of the study. To determine the features of motor-coordination preparedness of volleyball players aged 10–12 years in the context of improving defensive actions.

Methodology and organization of the study. The research was conducted at the bases of sports schools in China among volleyball players aged 10–12 years. The methodology was based on performing defensive-oriented exercises, including movements in a defensive stance, moving toward the ball, receiving the ball from below after side steps and lunges, as well as covering actions, which simultaneously improved defensive technique and developed agility, balance stability, spatial orientation, and accuracy of motor response [1].

Results of the study and discussion. The conducted tests showed that the development of motor-coordination abilities in volleyball players aged 10–12 years is accompanied by an increase in the effectiveness of defensive actions. In the 3×10 m shuttle run test, the average time for 10-year-old athletes was 10.1±1.9 s, for 11-year-olds – 9.6±1.6 s, for 12-year-olds – 9.1±1.4 s, which reflects an improvement in movement speed and agility. In the balance test, the average values were 26.8±8.7 s, 32.9±7.9 s, and 39.7±7.4 s, respectively, indicating increased stability and body position control when performing defensive actions. In the test for accuracy of ball passing after movement, the number of successful attempts out of 10 increased from 4.8±1.7 in 10-year-olds to 6.1±1.8 in 11-year-olds and 7.4±1.9 in 12-year-old athletes. The proportion of successfully performed defensive actions also increased, amounting to 42.6±6.8%, 51.3±7.1%, and 59.8±6.5%, respectively. The obtained data confirm that improving defensive actions contributes to the development of speed, stability, and accuracy of movements in young volleyball players.

Conclusion. The study showed that improving defensive actions is an effective means of developing motor-coordination abilities in volleyball players aged 10–12 years. To improve the quality of training, it is recommended to systematically include defensive-oriented exercises in the training process that develop movement speed, balance, and accuracy of motor actions.
