Abstract
Purpose: to show peculiarities of differentiated correction of junior school age children’s posture, considering tonic vibration reflex. Material: the research was conducted with participation of 62 junior school age children (7-10 years old boys and girls). All children have no sport training experience. All children were preliminary examined by qualified medical doctors. Tonic vibration reflex of lumbar spine was registered. Children fulfilled test exercises, which characterized power endurance of abdomen muscles, side of torso and back muscles. Results: external signs of posture disorders were absent in frontal plane. In 35 persons (65.8%) we registered one-side increased reflex excitability of nervous centers: from right side of backbone - in 28 children (72%); from the left side in 17 children (28%). Correction of posture with the help of correcting exercises can give steady effect only with simultaneous formation of correct posture habit. For this purpose it is necessary to create muscular-joint sense of separate body parts’ position. Conclusions: for determination of functional potentials of in-born muscular corset it is recommended to fulfill special test exercises. For local influence on lumbar spine muscles it is recommended to use exercise of asymmetric character.

Purpose: to show peculiarities of differentiated correction of junior school age children’s posture, considering tonic vibration reflex
Results of the researches Medical examination showed that in 35 persons (65.8%) we registered one-side increased reflex excitability of nervous centers: from right side of backbone – in 28 children (72%); from the left side in 17 children (28%)
With the help of registration of tonic vibration reflex (TVR) of lumbar spine symmetric muscles we found increased reflex excitability of right or left torso sides
Summary
Power endurance of torso side muscles, 60-90 sec. Statistic processing of results of torso side power endurance testing permitted to find the presence of asymmetry in static power endurance of torso right and left sides in most of the tested children. The examinations were used for determination of load parameters of correcting exercises for them to be adequate to children of control and experimental groups. In control group correcting exercises were oriented on prevention from posture disorders, without consideration of detected one side increased reflex excitability of appropriate nervous centers. In experimental group trainings were built on the basis of the received data of TVR of lumbar spine With it indicators of one-side increased reflex excitability of motor centers were considered. Series of experiments resulted in finding that health related effectiveness of symmetric correcting exercises, used by children with one-side increased reflex excitability, is restricted due to weak muscles on one side of torso [5, pg.124]. At the end of academic year, after experiment we carried out experts’ examination of children’s posture in control and experimental groups and summarizing registration of TVR
