SCHOOLCHILDREN’S FUNCTIONAL STATE UNDER INTENSIVE INFORMATION LOAD AT THE INITIAL ADAPTATION PERIOD TO EDUCATIONAL ENVIRONMENT

Aim. The research aim is to identify peculiarities of first forms schoolchildren's functional state (FS) under intensive information load during different phases of adaptation to educational environment. Methods. Schoolchildren's FS research was carried out at comfort and at test information load during the 2nd-3rd, 6-7th and 15-16th educational weeks at school. The complex of indices suitable for schoolchildren's FS mark was used. Results. The obtained results give the evidence that at the beginning of systematic education at school the additional information loads performed with comfort and with maximal speed cause the significant (p < 0.05-0.001) rise of common CNS activation level among 6-7 aged children, tension of mechanisms of FS regulation, shift of autonomic balance to the side of ANS sympathetic part activity predominance, central regulatory influences strengthening to heart rhythm, systematic hemodynamics stimulation, as well as anxiety level rise. It has been stated that in different phases of children's adaptation to education at school the additional information loads cause, in whole, similar changes of used indices among the children. Their shifts during test tasks performance had the same focus both at 2nd-3rd, 6-7th and at 15-16th weeks of education at school, thereat, the most expressed change of FS values fell on the first weeks of systematic education (p < 0.05-0.001). Conclusions. With the development of adaptation process to educational environment among the children in the conditions of test load the tendency of less significant changes of FS indices has been observed on the background of activity effectiveness rise.
