【 摘 要 】

The second period of childhood is a crucial stage of ontogenesis which is characterized by the intensive morphofunctional development in the body. When children start school, the regulatory mechanisms for controlling visceral functions are still developing, under the influence of which adaptive responses to ambient factors form themselves. Parameters of physical development are reliable markers of adaptive processes. The functional state in children living in the European North of Russia at this age period is influenced by a combined set of specific ecological-climatic conditions and school-related stress exposure. The tong-term studies undertaken by domestic and foreign research teams have so far focused on the effect of this complex set of factors on the morphofunctional development in children, targeting to determine the mechanisms for maintaining physical and mental health in schoolchildren. In this regard to the foreground comes the need of improving school environment in order to increase academic performance and reduce the increasing rates of stress, disadaptation and decompensation of physiological functions in children.
