The aim of this study was to evaluate the spinal thoracic curvature, lumbar curvature and pelvic tilt inclination in volleyball players .A total of 12male athletes aged 20 -28 years were evaluated in this study. The spinal mouse system(Ideag 360) was used to measure thoracic curvature, lumbar curvature and pelvic tilt in sagittal standing position. Study observed hyper thoracic kyphosis in volleyball players and no changes recorded in lumbar curvature & pelvic tilt inclination. In conclusion, the different type of high intensity sports training impact on angle of spinal curvatures. Repeating specific sports skills or movements for several times may generate specific spinal adaptations in sports persons.
