The aim of this study was to compare the difference in the position of the pelvis due to muscle imbalances resulting in a group of children aged 11-13 years from sports clubs to focus on karate, with a control group of children of the same age. The study concentrated on somatometric measurement characteristics and body composition (% BF) of children in middle school age, examination manual medicine techniques to determine the position of the pelvis and lumbar lordosis (Lewit, 2003). The main method used was a 3D motion analysis to determine the range of motion of the pelvis from the maximum to the maximum retroversion anteversion. There were evaluated pelvic movement in space (motion of pelvis segment against laboratory coordinate system - LCS) and lumbar spine movement towards pelvis (or motion of lumbar spine segment to pelvis segment). Results from 3-D motion analysis showed, that the range of movement (either compared the medians or averages), if compared karate with non-karate practising pupils, was not significantly different. Significant differences were found only in the values of sample standard deviations of motion (p=0.03). It can be said that despite the small numbers of subjects the data are able to demonstrate the difference between karate practising and karate non-practising pupils at least in the variability of ranges of movement.
