The article features the analysis of features of physiological adaptation and the rate of physiological development in boys and girls of preparatory kindergarten groups and 1 – 2 grades of grammar school. The analysis points out the differences of neurodynamic indicators, physiological adaptation and the degree of activity of the autonomic nervous system among 6 – 8 year-old boys and girls. It has been found that, regardless of age, boys are characterized by a lower level of development of mental   functions,   lower   balance   of   processes   of   excitation   and   inhibition in the central nervous system, with faster visual-motor response. They are characterized by a higher degree of tension of regulatory mechanisms. Individuals with symptoms of attention deficit and social-psychological deficits are often detected in this group. Girls display neurodynamic indicators that are most optimal for the corresponding age period, a high level of mental functions development; in this group we observed mainly balanced or parasympathetic influence on heart rate and more satisfactory functional state.

The current paper features the impact the lifestyle of modern teenagers has on their psycho-physiological development. It shows an analysis of the nutrition and motor activity of adolescents aged 12-13 and the gender differences in their psycho-physiological and morphofunctional development. A complex analysis of lifestyle factors (day regimen, nutrition balance, level of motor activity) have allowed the authors to classify 66,7 % of adolescents as«low risk» of health disorders development and 33,3 % as an «increased risk» group. The«low risk» group has a greater number of representatives with harmonious physical development, a high level of neurodynamic indicators, memory and attention. A correlation analysis of lifestyle and indicators of morphofunctional and psycho-physiological development has been carried out. The interrelation between the features of nutrition and the motor activity of adolescents has been established by the indicators of psycho-physiological development.
