The growth and development of children aged 7-10 years takes place under conditions of continuous learning, and the level of fatigue increases by the end of the school year. Environmental factors of the Kola Peninsula play a special role here. the process of adaptation of the organism takes place in all age and gender groups. The most obvious is the reactivity of the cardiovascular and sympathetic-adrenal systems to physical load, which enhances the correlation links between indicators of the two active systems. It happens in the following way: by the end of the academic year, in all age and gender groups before the polar day, a proven shift of the observed indicators is recorded. The results obtained provide a comprehensive picture of age-related adaptation changes and increase in the level of fatigue in the arctic climate conditions of the Kola Peninsula. Examinations of children aged 7-10 years showed that age dynamics of cardiovascular and sympathoadrenal systems indicators is non-linear and significantly depends on specific parts of the academic year. This may be due to the periodicity of the polar night, namely, as the functional capabilities of particular systems tend to increase with age, certain indicators have a wave-like character of changes.
