The results of the research done in the theoretical and practical fields of study show the degree of reactivation of the growing body under the influence of the educational stress and the suprainformation doze. The environment determines diverse extremes of action that train physiological reactions of adaptation. The main task of the research was getting to know the diversity of the amplitude of these reactions and the limits of maintaining the homeostazy of the teenage body. Along the research some aspects of the problem were investigated: psychoemotional, physiological etc. Dividing the experimental sample of 289 students was done based on the level of anxiety, temperament, neurotism, sex, age, nervous state.
The adaptive results are dependent on the nervous state and the endocrine of the researched person. Hipotalamo-hipophizar stimulation determines the hormonal adenohipophizar secretion, with answers upon the secretion of the suprarenal, tiroidian, gonadalian hormones. The neuro-endocrino-metabolico research of the cognitiv stress was tested with th help of:
The saliva cortisol, being determined through a irregular method increases the
concentration depending upon the sex, age and temperament.The neuro-encephalic disturbances
were determined by the hypovoltation of the alpha waves, with the diminuation of the capacity to
adapt to sound and light reactions, hyperventilation, and of the cognitive proceses (attention,
memory and motivation).The adequate neuro-endocrine reactions assure the resistence and the
equilibrium0 of the body withoud harm and limited conditions. The level of adaptation of the
teenagers has a genetic support, it is dependent on the intensity and the frequency of the stressful
situations, and of the individual reactivity of the researched subject. The same stress agent will
cause different answers at different persons, depending on the homeostatic equilibrium, body
resistence and the socio-cultural environment.
