Background. Her symmetry is in frontal area the basic criterion of opinion of attitude body. Have the same name osseous points in this plane should to be arranged in relation to axis of spine symmetrically and to be on equal height, and teenagers’ line spinous of spine should make up right line. Above mentioned conditions happen fulfilled seldom, because at man symmetry never is full. This results mainly with asymmetric position of internal organs, the environmental influences whether the only process of lateralisation. Material and methods. It triple investigations were hugged was 298 – personal group the same children. The computer set to analysis of size of asymmetry was applied to of opinion of attitude body using the phenomenon of projection moire thopography. Results. Asymmetries in frontal area at studied boys and girls be shaped similarly and stepped out in both groups in considerable percentage. Absolute differences in position of have the same name osseous points concerned distances from teen-agers’ line the bottom executioners of shoulder-blades the line spinous, height of triangles of waist as well as position basin in frontal area, however the most seldom both children’s groups asymmetries concerned in frontal area the depression angle. It it was showed was moreover that the asymmetries undergo decrease between 7 and 8 year of life and renewed enlargement between 8 and 9 year of life. The statistical also between years analysis show on similarity be shaping to asymmetry of trunk at boys and girls. Conclusions. 1.Frequency of occurrence in grounds of trunk the asymmetry changed along with the age the studied children. She be shaped in dependence from side of body differently. 2.More often considerable asymmetry was affirmed was at 7 year old children’s and 9 years old children’s, more seldom at 8 years old children’s. They asymmetries these in this lid belonged to reasonable.
