Introduction. In table tennis, training with a large number of balls is widely used by Chinese coaches at all stages of training, i.e. in tennis.It allows to significantly improve technical and tactical skills, reaction, motor skills and abilities, as well as improve the psychophysical abilities of players [1, 2].
The purpose of the study is to identify the effectiveness of the effect of using the plyometric method of sensorimotor stimulating effect of a large number of balls on the pace of movements of the playing hand of table tennis players at the training stage of preparation.
Methodology and organization of the study In order to study the pace of movements of tennis players, a tapping test was used based on performing stereotypical tapping movements for 30 seconds on a special form proposed by E. N.According to P. Ilyin, 1972. The study was conducted at the sports school of GBU do MGFSO, the Table tennis department of the Moscow Sports Department. Moscow. 24 tennis players of the training stage of 10-12 years old, divided into equivalent control and experimental groups, took part in the emerging pedagogical experiment, which lasted 4 months.
The program of the pedagogical experiment included plyometric exercises with a large number of balls, performed in series of 30-40 balls.
The results of the study and their discussion The analysis of the indicators of the tempo of movements of non-playing and playing hands in the tapping test of tennis players in the control and experimental groups did not reveal significant differences in these indicators, which indicates the homogeneity of the groups. However, there was a slight increase in the improvement in the rate of movement of the non-playing hand both in the control group by an average of 0.92 strokes and in the experimental groups by an average of 4.41 strokes. This indicates a positive transfer of this quality from a gaming hand to a non-gaming one. At the same time, at the end of the pedagogical experiment, the tennis players of the experimental group showed statistically significant changes in the tempo of the playing hand (p=0.020), compared with the control group of tennis players, where it was not possible to establish statistically significant changes (p=0.561)
Conclusion. The data obtained confirm the effectiveness of the influence of the methodology for improving the speed abilities of the upper extremities of players and, in particular, the pace of movements of the playing hand in table tennis at the training stage of preparation by using plyometric orientation exercises of a large number of balls.
