Lumbar spine range of motion (ROM) is a key component of injury prevention and normative data has not currently been determined for an elite gymnastics population. In current clinical practice, it is commonplace to measure sagittal spinal alignment, during 'high-load, low-dynamic' control tasks, subjectively, while also only considering the lumbar spine as a single segment.
To develop normative data for total lumbar spine ROM and ROM during a simulated landing task (SLT) in an elite gymnastics population, evaluating findings in the context of the existing biomechanical literature.
Repeated measures, cross sectional design.
Lumbar spine and low lumbar spine (LLS) ROM during a SLT were measured, using the Dorsa Vi: Vi Perform™ system in asymptomatic male and female elite gymnasts. Values for maximal ROM and LLS angle during the SLT were collated and descriptively analyzed. Lumbar ROM and posture was evaluated in relation to the current biomechanical literature and a proposed Conceptual Compressive Lumbar Load Distribution Model (CCLLDM).
Thirty elite gymnasts (15 male, 15 female), participated. Participants were members of the British Artistic Gymnastics elite senior and junior training program and were between the ages of 16 to 30 years. Mean (SD) maximal lumbar spinal movements were 64.23˚ (6.34 °) for flexion and 25.89˚ (11.14 °) for extension. During the SLT, participants performed lumbar spine flexion of 15.96˚ (8.80 °), when considered as a single segment. When considering the lumbar spine as a two segment model the LLS position during the SLT was towards end range anterior pelvic tilt, suggesting LLS extension.
These data provide a baseline for asymptomatic lumbar spine movements in an elite gymnastics population and provides insight into upper and lower lumbar spine movement during a SLT. The data and newly developed CCLLDM provide clinicians with a potential framework to identify sporting skills that may be associated with increased spinal tissue load.

腰椎活动度（ROM）是预防损伤的关键组成部分，目前尚未确定精英体操运动员群体的规范数据。在当前临床实践中，在“高负荷、低动态”控制任务期间主观测量矢状面脊柱排列是常见做法，同时也仅将腰椎视为单个节段。
为精英体操运动员群体制定全腰椎ROM以及模拟着陆任务（SLT）期间的ROM规范数据，并结合现有生物力学文献评估研究结果。
重复测量、横断面设计。
使用Dorsa Vi: Vi Perform™系统测量无症状男性和女性精英体操运动员在SLT期间的腰椎和下腰椎（LLS）ROM。整理并描述性分析SLT期间的最大ROM和LLS角度值。根据当前生物力学文献和提出的概念性腰椎压缩负荷分布模型（CCLLDM）评估腰椎ROM和姿势。
30名精英体操运动员（15名男性，15名女性）参与。参与者是英国艺术体操精英高级和初级训练项目的成员，年龄在16至30岁之间。平均（标准差）最大腰椎运动屈曲为64.23˚（6.34°），伸展为25.89˚（11.14°）。在SLT期间，当视为单个节段时，参与者的腰椎屈曲为15.96˚（8.80°）。当将腰椎视为双节段模型时，SLT期间LLS位置朝向骨盆前倾终末范围，提示LLS伸展。
这些数据为精英体操运动员群体无症状腰椎运动提供了基线，并深入了解了SLT期间上、下腰椎的运动。这些数据和新开发的CCLLDM为临床医生提供了一个潜在框架，以识别可能与脊柱组织负荷增加相关的运动技能。
