OBJECTIVE: To identify the postural alterations among children aged 8 to 12 years who perform Olympic gymnastics. METHOD: Eighty-four students aged 8 to 12 years were assessed: 38 who were participating in Olympic gymnastics and 46 who were not. Each child was photographed in the anterior and posterior frontal planes and in the sagittal plane. The photos were analyzed using the CorelDraw v. 11.0 software. The line-guide and dimension tools (angular, vertical and horizontal dimensions) were used to determine the parameters of the nineteen qualitative and five quantitative variables. RESULTS: Comparison between the test group subjects (TG) and control group subjects (CG) showed significant differences in the variables of medial rotation of the femur (CG 56.52%; TG 39.47%), antepulsion of the pelvis (CG 43.48%; TG 76.32%) and trunk rotation (CG 67.39%; TG 23.68%). There were also found significant differences in the measurements of knee valgism (CG 4.06 ± 2.32 cm; TG 3.14 ± 1.49 cm), pelvic inclination (CG 0.69 ± 0.39 cm; TG 0.53 ± 0.33 cm) and tibiotarsal angle (CG 86.93 ± 2.90 cm; TG 87.11 ± 4.17 cm). CONCLUSION: Analysis of the results showed a tendency towards better alignment of the lower limbs in the test group than in the control group. There was greater anterior pelvic inclination and a tendency towards lumbar hyperlordosis in the test group. These factors may predispose individuals participating in Olympic gymnastics to misalignment of skeletal structures, thereby leading to painful conditions that may limit their sports activities.
