在前交叉韧带（ACL）损伤的女运动员中观察到持续的生物力学和跳跃能力改变。本研究的目的是检查是否生物力学跳跃的差异仍然存在于一个队列的精英女子手球运动员与以前的ACL重建几年后返回到顶级比赛。为了实现这一目标，通过使用单个惯性传感器单元（IU）的直接力学简化分析。21名优秀女子手球运动员（6名前交叉韧带重建运动员和15名未受伤的对照运动员）在前交叉韧带重建手术后6.0 ± 3.5年接受评估。进行双侧和单侧垂直跳跃以评估功能性能，并采用单个惯性传感器单元以收集3D加速度和3D方向数据。先前ACL重建分析的运动员在ACL重建后几年的双侧和单侧跳跃动作中，显示出与三维轴（X-Y-Z）支持加速度和不同跳跃阶段持续时间相关的显著（p < 0.05）变化，包括跳跃性能值。通过使用IU装置识别所遇到的缺陷，可以为临床医生提供一种新的可靠工具，用于临床环境中的运动分析。
Persistent biomechanical and jumping capacity alterations have been observed among female athletes who have sustained anterior cruciate ligament (ACL) injuries. The purpose of this study was to examine if biomechanical jumping differences persist among a cohort of elite female handball players with previous ACL reconstruction several years after return to top-level competition. In order to achieve this goal, a direct mechanics simplified analysis by using a single Inertial Sensor Unit (IU) was used. Twenty-one elite female (6 anterior cruciate ligament reconstructed and 15 uninjured control players) handball players were recruited and evaluated 6.0 ± 3.5 years after surgical anterior cruciate ligament reconstruction. Bilateral and unilateral vertical jumps were performed to evaluate the functional performance and a single inertial sensor unit was employed in order to collect 3D acceleration and 3D orientation data. Previously ACL-reconstructed analysed athletes demonstrated significant (p < 0.05) alterations in relation to the three-dimensional axis (X–Y–Z) supported accelerations and differing jump phase durations, including jumping performance values, in both bilateral and unilateral jumping manoeuvres several years after ACL reconstruction. Identification of the encountered deficits through the use of an IU devise could provide clinicians with a new reliable tool for movement analysis in a clinical setting.
