网球发球技术与腰背损伤关系的生物力学分析

为探讨网球发球技术与腰背损伤之间的关系，探寻导致腰背损伤的技术性原因，采用三维高速摄像法和图像解析法，以健康业余网球运动员为对照，对患有腰背部损伤业余网球运动员发球技术进行对比分析。结果表明搔背期末躯干扭转过大可能是造成业余网球运动员腰背损伤的直接原因，腰腹肌力量素质较差和抛球较偏是导致这一问题的主要技术性因素，并针对这些问题提出相应的解决办法，供教练员和业余运动员参考。

A Biomechanical Analysis of the Relationship between Tennis Serve Technologies and Lumbar Spinal Cord Injuries

In order to research the relationship between tennis serve technologies and lumbar spinal cord injuries, and to explore the technical reasons of lumbar spinal cord injuries, tennis service technologies of amateur tennis players with lumbar spinal cord injuries are analyzed by the methods of three - dimensional high speed pho- tography and image analysis, and by the comparison with healthy amateur tennis players. The results show that the lumbar spinal cord injuries are directly caused by the oversized twist at the end of the back forward trunk, and that the poor strength of abdominal muscles and the throwing ball＇ s inappropriate position are the main technical factors of this problem. In this paper, the corresponding solutions are provided for the trainers and the amateur tennis play- ers.
