Training and improving billiard technique in students with respect to the sequence of solutions to motor tasks in the nervous system

Aim. The paper aims to compare the effectiveness of training of billiard players, who follow the program of sports school, and those, who participate in the experiment for improving billiard technique based on the sequence of solutions to motor tasks in the nervous system. Materials and methods. The experiment involved control and experimental groups of young males and females of 8 people each with sports skills from 1st junior category to a candidate for master of sport in billiards. For an objective assessment of billiard skills acquisition a force platform was used to study muscle coordination and neural regulation of vertical position (patent № 2547991 and № 2547992, Russia). Results. At the beginning of the experiment, two groups were equal in competitive performance (Z = 0.866, р = 0.3865). The experimental method allowed athletes to increase a growth rate of kinesthetic sensitivity by 33.5 % (from 0.242 ± 0.08 units to 0.161 ± ± 0.07 units (хaverage ± σ)), muscle synergy - by 56.1 % (from 95.9 ± 31.1 units to 117.6 ± 27.7 units (хaverage ± σ)). In the control group, a deterioration of kinesthetic sensitivity by 6.3 % was recorded (from 0.347 ± 0.12 units to 0.369 ± 0.12 units (хaverage ± σ)), as well as a decrease in muscle synergy by 15.8 % (from 66.4 ± 30.8 units to 55.9 ± 20.1 units (хaverage ± σ)). The analysis of billiard performance is confirmed statistically (Z = -2.252, p = 0.02436) in favor of the experimental group. Conclusion. The results of the study statistically prove the effectiveness of the experimental method of improving billiard technique based on the sequence of solutions to motor tasks in the nervous system. The coach's support of natural biological sequence when solving motor tasks in the nervous system allowed the experimental group to double its competitive performance compared to the control group.
