Introduction. It is known that badminton is characterized by a wide variety of motor acts performed in variable situations. Thus, the accuracy and speed of the player's actions will largely be determined by the quality of perceptual-motor functioning: the speed of transmission and processing of sensory information, the ability to arbitrarily control motor actions, the level of intermuscular and intramuscular coordination, the quality of postural control (J. P. Vinnik, 2010; H. Jin et al., 2011).
The aim of the study is to identify the relationship between the indicators of the perceptual-motor complex and the effectiveness of badminton players' gaming activity.
Methodology and organization of the study. 65 badminton players of various age and qualification groups took part in the study. Spearman's rank correlation coefficient (r) was used to assess the relationship between the indicators of the perceptual-motor complex and the effectiveness of gaming activity.
The results of the study and their discussion. In badminton players‑dischargers of the second childhood group, reliably strong correlations were found between the background values of the bioelectric activity of the muscles of the working arm and the average speed of movement of the pressure center and the effectiveness of performing protective actions, between the deviation of the pressure center back and the effectiveness of the feed. Badminton players with higher sports qualifications of adolescent and adolescent ages have increased correlations between indicators of the quality of postural balance, an electromyogram at rest, the ability to voluntary muscle relaxation and the effectiveness of gaming activities.
Conclusions. With the increase in the qualification and age of badminton players, there is an increase in the number of significant correlations between the indicators of the perceptual-motor complex and the effectiveness of gaming activity, which, apparently, is the result of adaptive rearrangements arising under the influence of long-term training load.
