    Aim: The reaction of urgent adaptation of the sympathetic-adrenal system (SAS) and the adrenal cortex (AC) to the local static load in 7–9-year-old children was studied, taking into account their gender, age, and initial vegetative tone. Methods: A shift in the excretion of catecholamines (CAs) and their precursors, metabolites of glucocorticoids and androgens, in response to the impact of a dosed load, was evaluated. It was found that the dynamics of the studied indicators in 9-year-old girls, in a state of sympathicotonia and normotonia, is multidirectional. Results: The observed decrease in excretion of CAs and dihydroxyphenylalanine or their insignificant increase is accompanied by an increase in the functional activity of AC and, to a greater extent, its androgenic function. Conclusion: All these evidenced about the features of neuroendocrine interrelations in the mechanism of adaptive reactions of 9-year-old girls, greater stability of the pituitary-adrenal system, providing metabolic processes in the growing organism. Unlike with 7-year-old boys, normotonics and vagotonics, and 8-year-old sympathotonics, whose local static load has a simultaneous decrease in the spare capacities of SAS and AC. This indicates the manifestation of fatigue and asthenization of the schoolchildren in the process of learning activity.
