The aim of this study was to evaluate functional and structural changes in the lumbar spine which occurred as a consequence of playing field hockey.
The research group consisted of 20 male professional field hockey players. Computed tomography scans were collected to define the radiological density of the vertebral bodies and to calculate Young's modulus. An electrogoniometer was used to measure the range of movement. Geometric parameters, such as Lumbar Lordosis Angle, Index of Lumbar Lordosis, Whitmann-Ferguson Angle and Anterior Pelvic Tilt, were also measured.
The values describing lumbar lordosis increased linearly with years of training and were significantly greater than those reported in the literature. Field hockey players displayed a larger range of flexion, side bending and rotation to the right. An analysis of radiological density discovered significantly high values. An analysis of Young's modulus showed that the vertebral bodies become more fragile.
The results show that overuse changes in the lumbar spine of field hockey players are severe and highly correlated with years of training.
本研究旨在评估由于进行曲棍球运动而导致的腰椎功能和结构变化。
研究组由20名男性职业曲棍球运动员组成。收集计算机断层扫描以确定椎体的放射密度并计算杨氏模量。使用电子测角仪测量活动范围。还测量了诸如腰椎前凸角、腰椎前凸指数、惠特曼-弗格森角和骨盆前倾等几何参数。
描述腰椎前凸的数值随训练年限呈线性增加，且显著高于文献报道的值。曲棍球运动员表现出更大的右侧前屈、侧屈和旋转范围。放射密度分析发现数值显著偏高。杨氏模量分析表明椎体变得更加脆弱。
结果表明，曲棍球运动员腰椎的过度使用变化严重，且与训练年限高度相关。
