[The forming of child and adolescent adaptability]

Adaptability is an ability of the organism to spend its functional reserve in order to keep the balance with the environment and then make up for the use of this reserve. The adaptation of a growing organism to the environment is an intersystem process. The condition of functional intersystem regulation and cardiac rhythm variability in particular, serve as indicators of child adaptability. Adaptability is formed under the influence of such biological factors as heredity, age, gender, health status, and such environmental ones as nutrition balance, quality of life, physical activity, day regimen, and learning conditions. The authors developed a conceptual model of interrelation between biological and environmental factors in the forming of child adaptability.
