Shape of the Sagittal Curvatures of the Spine in Youthful Female Volleyball Players

The goal of this study is to assess the formation of the sagittal curvatures of the spine in healthy girls practicing volleyball versus their untrained peers. Research questions: 1. Is there a differentiation in values of thoracic kyphosis, lumbar lordosis angles, and compensation ratio among girls practicing volleyball and their untrained peers? 2. Does practicing volleyball determine the frequency of correctness in the lumbosacral inclination, the shape of the curvature of the thoracic kyphosis and lumbar lordosis? 3. Does practicing volleyball determine the frequency of types and subtypes of body posture?
