The purpose of the work is to find out the influence of the application of the Go game in combination with physical exercises on the indicators of cognitive and neurodynamic properties of children 6 years. Material and methods. The study was attended by 30 first-class children, aged 6 years. Children were divided into 3 groups of 10 people each. The two groups became experimental, one control group. In the first experimental group, children played the game Go, in the second - the game Go in combination with physical exercises, in the control group - under the usual program of a prolonged day. The children of the experimental groups engaged in the game Guo twice a week during the month. Before and after the experiment, the technique was tested by Schulte, and according to Yermakov's technique (computer program "Selecting a button"). Experimental groups were engaged in the developed techniques, the children of the control group were engaged in the standard program of the extended day group. Results. The application of the game of Go positively affects mental capacity and neurodynamic functions, with the influence on neurodynamic functions is increased by the use of the game Go in combination with physical exercises. The significant influence of the nature of classes in groups (Guo Guo, Gore in combination with physical exercises, regular classes in a day-to-day program) is shown on the cognitive and neurodynamic functions of children 6 years of age. Reliable influence was determined by Schultt's tests (time on the first table and efficiency) at p <0.001 and by Ermakov's test for determining the reaction rate of choice when changing the position of an object in space in three attempts at p <0.001. Conclusions. The results of the research show that the application of the Go game positively affects the indicators of cognitive functions and neurodynamic properties of children 6 years. The lesson only of the game of Go is most influences on mental performance, and the pursuit of the game Go in combination with physical exercises most strongly improves the neurodynamic parameters associated with the need to switch attention, the speed of the reaction of choice to objects whose positions change in space.
