Purpose: The purpose of this work was to assess changes in body posture in a group of 6-year-old boys training judo, compared to a control group, in three repeated examinations.
Methods: The study included 88 boys aged 6. Fifty-one of them started judo training in sports clubs at the beginning of the school year (JU). The control group included 37 boys attending reception classes in primary schools, selected at random (NT). Body posture was assessed 3 times at 3-month intervals, according to the general methodology of the Moire's technique, and 15 body posture indices were obtained as a result: 7 in the sagittal plane, 1 in the axial plane and 7 in the coronal plane. The system for photogrammetric body posture assessment of CQ Elektronik System was used in this study.
Results: The ANOVA test showed that neither the group factor - the fact of judo training - nor the time factor had any significant effect on the number of "deviations from normal values" of body posture (p > 0.05). Statistically significant intergroup differences were noted for six body posture indices measured with the Moire's method.
Conclusions: Steadily decreasing numbers of "deviations from normal values" of body posture indices in the JU group were observed over the three examinations. Regular 6-month judo training had a statistically significant effect on a decrease of body rotation in the axial plane - the effect of judo training may be considered corrective in this case.
