Variação da curvatura geométrica da coluna vertebral ocasionada por recolocações de marcadores em avaliações posturais com cinemetria. Educação Física em Revista, Brasília, DF, v. 9, n. 2, p. 23-40, 2015.1983-6643http://repositorio.bc.ufg.br/handle/ri/20694Currently, the quantification of the lumbar lordosis and thoracic kyphosis, in postural assessments with cinemetry, using angular variables based methods, is highly susceptible to marker reapplication errors. This study aimed to analyse the variation, between maker reapplications, of the angle and the geometric curvature, in saggital plane, in postural assessments with cinemetry during running. Four men (36-61 years; 1.63-1.77 cm; 61.0-75.0 kg) participated in two postural evaluation sessions, running on a treadmill, 9.3 km/h, on different days. The geometric curvature peaks and the angles, in the thoracic and lumbar regions, were computed, in the trunk sagittal plane, for quantification of lumbar lordosis and thoracic kyphosis. The angles were more sensitive to palpation simulated errors. In both the thoracic region and lumbar region the peak of curvature was more reproducible than the angle. Although these results, the lumbar peak of curvature presented inconclusive results regarding the reproducibility between tests. It will be needed, further studies with more representative samples, to obtain conclusive results and generalizations.porAcesso AbertoCinemetriaPosturaBiomecânicaColuna vertebralSpinePostureBiomechanicsArtigo
