Justification of the need to search and use pre-nosological markers of functional deviations of posture of children 6-7 years at the stage of formation of student skills

The problem of forming a healthy posture of schoolchildren is in dire need of an effective solution over the past decades. So according to K.I. Khodatskaya, A.A. Kuts, 2020 and others, posture disorders in children of primary school age are 62.8%, and among adolescents 11-15 years old they reach 80-90% of the total number of students. Purpose: theoretically and experimentally substantiate the feasibility of finding and using pre-nosological markers of posture disorders of students 6-7 years old at the stage of adaptation of the musculoskeletal system for school educational loads. The methodological basis of the study was the component analysis of the second variant of the Romberg test, on the basis of which the indicators of stability coefficients of the equilibrium function (EMF) and asymmetry of the equilibrium function (EDF) were calculated. Research methods: theoretical analysis of scientific and methodological literature, dynamic pedagogical observation, Romberg functional test (second option), goniometry of the spine according to V. A. Hamburtsev, stating experiment, statistical methods. Contingent of subjects: the study involved 12 boys 6-7 years old, first grade students of secondary schools of the city, who were assigned to the main group for health reasons. Scientific novelty: for the first time developed a complex of pre-nosological markers of posture for students 6-7 years old, who start school load; A preventive approach to the formation of posture of students 6-7 years old at the stage of adaptation to educational loads is substantiated, criteria that determine the risk group regarding the predicted occurrence of certain functional deviations in the posture state are worked out. The effectiveness of the goniometry method for studying the dynamics of indicators of the morphofunctional state of the spine of students 6-7 years old during the first year of school has been confirmed. The practical significance of the results obtained is that primary school teachers and parents will receive a ready-made toolkit based on innovative technologies for carrying out specific health-saving work in the direction of forming the posture of children 6-7 years old during the first year of schooling and the entire period of schooling.
