Human postural system is taken as complex biological system with specific input and output time characteristics, in this study. Evaluation of measured output characteristics is useful in medical diagnostics or in describing postural system disorders. System theory principle provide suitable basis for postural signals analysis. Participating volunteers were instructed to maintain quiet upright stance posture on firm support surface of stabilometric platform for 60s. Postural system actuation was realized by vibration stimuli applied bilaterally on Achilles tendons for 20s. Postural reaction signal, its time profile and static and dynamic characteristics were evaluated by Method of Developed Statokinesigram Trajectory (MDST).
The aim of this paper was to study a number of 34 athletes practicing different kinds of sports activities, in order to determine whether they have developed a certain spine deficiency and if there is any association between the type of sports they practice and the postural changes they develop.
Methods: In this study we have enrolled 12 members of the men’s volleyball team of the “West University of Timisoara”, 9 members of the men’s football team ASU Politehnica Timișoara, and 13 members of the men’s basketball team BC SCM Timișoara. Postural analysis was carried out with the Zebris CMS-10 from the mechatronics department of the Politehinca University Timisoara, a device that determines the spatial coordinates of the spinous processes. From the obtained data we have established the angle of the spinal deviation both sagittal and frontal, in a similar manner as with the Cobb method.
Results: We have observed a reduction in the spinal curvature in volleyball players; 8 out of 12 had values under the normal range that can in time lead to a rigid spine. 7 players from the basketball team presented values out of the normal range for kyphosis and 8 of them for lordosis, while all except two of the team players present with a front plane deviation of the spine. From the evaluation of the football players from ASU Politehnica Timișoara we cannot generalize a deviation in the sagittal plane, but all of them present deviations in the frontal plane.
Conclusion: Professional athletes can also present postural changes determined by the positions they most frequently adopt depending on the type of sports they practice.

Variables and abbreviations for 3D postureanalysis.
ShD Shoulder displacement
The variable expressed in centimetres indicates elevation/depression of the left/right frontal plane. Results with positive values are with regard to the right shoulder elevation, while negative values indicate the left shoulder elevation.
