The purpose of the study is to analyze the development of motor and coordination abilities of volleyball players aged 10-12 in China.
Methodology and organization of research. The testing was conducted on the basis of Chinese sports schools among children aged 10-12 who regularly practice volleyball. The following tests were used to assess motor and coordination abilities: a 3x10 m shuttle run, a balance test (standing on one leg), and a test for the accuracy of hitting the ball on target.
Research results and their discussion. The conducted tests revealed an improvement in motor and coordination abilities with age, due to the peculiarities of physical development, the methodology of the training process and the gradual improvement of neuromuscular coordination in children.
In the 3x10 m shuttle run test, the average time to complete the distance was 10.2±2.3 seconds for 10‑year‑old volleyball players, 9.8±1.7 seconds for 11–year‑olds, and 9.3±1.9 seconds for 12–year-olds. The reduction in time is associated with improved reaction speed, general dexterity, and the ability to quickly change direction, which is critical. for effective execution of game elements in volleyball. The balance test (standing on one leg) showed that the ability to maintain balance increases significantly with age: the average time for 10‑year‑old athletes was 25.3±9.6 seconds, for 11–year-olds - 31.6±8.1 seconds, and for 12‑year–olds - 38.4±8.8 seconds. The improvement in this indicator is due to improvement of the vestibular apparatus and strengthening of stabilizer muscles, which helps athletes to perform more effectively the elements of volleyball technique, such as blocking and receiving the ball.
In the ball accuracy test, the average number of accurate hits out of 10 attempts increased with age: 10‑year–olds had 4.5±1.8 hits, 11‑year–olds had 5.7±2.1 hits, and 12‑year–olds had 7.1±2.2 hits. Increased accuracy is associated with the development of hand-eye coordination, improved throwing technique and movement accuracy, which plays an important role in the effectiveness of passing and serving in the game.
Conclusions. The study showed that regular training aimed at developing motor and coordination abilities significantly improves the performance of young volleyball players aged 10-12 years. To increase the effectiveness of training, it is recommended that exercises aimed at developing speed, balance and precision of movements be systematically included in the training process.
