: Acute and chronic injuries are frequent in volleyball. Biomechanics of sport-specific tasks can influence the risk of injury, which is also related to specific court positions. We investigated posture at raster-stereography, balance, and dynamic tasks using inertial motion units to find differences between roles, which can be predictive of a higher risk of injury. : We cross-sectionally evaluated amateur volleyball athletes. Participants were divided into roles as outside hitters, setters, middle blockers, and opposite hitters. We excluded the "libero" position from our analysis. : Sixteen players were included in the analysis. A statistically significant difference was found in left lower limb stiffness among the outside hitter and setter groups. : Differences in stiffness might be related to the different training and the different abilities among the two groups. Raster-stereography is extending its indications and should be implemented for non-invasive postural analysis. The use of inertial motion units provides objective measurements of variables that could go unrecognized within a clinical evaluation; its use should be considered in injury preventive programs.
急性和慢性损伤在排球中很常见。运动专项任务的生物力学可以影响受伤的风险，这也与特定的球场位置有关。我们使用惯性运动单元研究了光栅立体摄影、平衡和动态任务中的姿势，以发现不同角色之间的差异，这些差异可能预示着更高的受伤风险。
我们对业余排球运动员进行了横断面评估。参与者被分为外击球手、二传手、中间拦网手和对方击球手。我们将“自由人”位置排除在分析之外。
共有 16 名运动员参加了分析。在外击球手和二传手组中，左下肢刚度存在统计学显著差异。
刚度的差异可能与两组的不同训练和不同能力有关。光栅立体摄影正在扩大其适应症，应将其用于非侵入性姿势分析。惯性运动单元的使用提供了变量的客观测量，这些变量在临床评估中可能被忽视；在预防受伤的计划中应考虑使用它。
