This study aimed to investigate the bowling techniques of female fast bowlers and identify any association between a history of low back pain (LBP) and the movement patterns of the thorax relative to the pelvis during the delivery stride of the bowling action. Three-dimensional kinematic data were collected from 26 elite Australian female fast bowlers using an eight-camera Vicon motion analysis system. Nineteen bowlers used a mixed action, 6 bowlers used a semiopen action, and 1 bowler used a side-on action. Fourteen bowlers had a history of LBP. Eight of these 14 bowlers used a mixed action, and bowlers with more shoulder counterrotation were no more likely to have a history of LBP. Bowlers with a history of LBP positioned the thorax in more left lateral flexion relative to the pelvis between 73-79% of the delivery stride, and moved the thorax through a significantly greater range of lateral flexion relative to the pelvis during the delivery stride compared with bowlers with no history of LBP. This information will give coaches and support staff a better understanding of female bowling technique and may facilitate better screening practices for elite female cricketers.
本研究旨在调查女子快速投球手的投球技术，并确定在投球动作的助跑阶段，下背痛（LBP）病史与胸部相对于骨盆的运动模式之间是否存在关联。使用八台摄像机的Vicon运动分析系统，从26名澳大利亚精英女子快速投球手那里收集了三维运动学数据。19名投球手采用混合动作，6名投球手采用半开放式动作，1名投球手采用侧投动作。14名投球手有下背痛病史。这14名投球手中有8名采用混合动作，且肩部反向旋转较多的投球手患下背痛的可能性并不更高。与没有下背痛病史的投球手相比，有下背痛病史的投球手在助跑阶段73%-79%的时间里，胸部相对于骨盆处于更多的左侧屈曲位置，并且在助跑阶段胸部相对于骨盆的侧向屈曲范围明显更大。这些信息将使教练和辅助人员更好地了解女子投球技术，并可能有助于为精英女子板球运动员制定更好的筛查方法。
