损伤预防训练已被证明可以有效降低非接触性前交叉韧带（ACL）损伤的发生率;然而，这些训练计划成功的根本原因尚不清楚。旨在研究已被证明可以降低ACL损伤发生率的ACL损伤预防计划是否会在跌落着陆任务期间改变矢状面髋关节和膝关节生物力学。描述性实验室研究。30名没有膝关节损伤史的女子俱乐部足球运动员（年龄范围，11-17岁）参加了这项研究。在参加为期12周的ACL损伤预防训练计划之前和之后，收集每位参与者执行降落任务时的运动和地面反应力。在ACL损伤预防训练后，参与者表现出膝盖伸肌力矩减少（P = 0.03），髋部能量吸收增加（P = 0.04），膝盖与髋部伸肌力矩比减少（P = 0.05），膝盖与髋部能量吸收比减少（P = 0.03）。参与ACL损伤预防训练计划减少了对膝伸肌的依赖，改善了髋伸肌的使用，这可以解释这种类型的训练计划对ACL损伤的保护作用。基于这些发现，临床医生可以更好地了解ACL损伤预防训练，如预防损伤和提高性能（PEP）计划，如何改变髋关节和膝关节的运动行为。此外，研究结果可能支持PEP计划或类似计划的实施，旨在改善临床医生的髋关节使用，以减少膝关节负荷和随之而来的损伤。
Injury prevention training has been shown to be effective in reducing the incidence of noncontact anterior cruciate ligament (ACL) injury; however, the underlying reason for the success of these training programs is unclear. To investigate whether an ACL injury prevention program that has been shown to reduce the incidence of ACL injury alters sagittal plane hip and knee biomechanics during a drop-landing task. Descriptive laboratory study. Thirty female club soccer players (age range, 11-17 years) with no history of knee injury participated in this study. Kinematics and ground-reaction forces were collected while each participant performed a drop-landing task prior to and immediately after participation in a 12-week ACL injury prevention training program. After ACL injury prevention training, participants demonstrated decreased knee extensor moments (P = .03), increased energy absorption at the hip (P = .04), decreased knee-to-hip extensor moment ratios (P = .05), and decreased knee-to-hip energy absorption ratios (P = .03). Participation in an ACL injury prevention training program decreased reliance on the knee extensor muscles and improved use of the hip extensor muscles, which may explain the protective effect of this type of training program on ACL injury. Based on these findings, clinicians can better understand how ACL injury prevention training, such as the Prevent Injury and Enhance Performance (PEP) Program, may change movement behavior at both the hip and knee. Furthermore, the study findings may support the implementation of the PEP Program, or a similar program, for clinicians aiming to improve use of the hip in an effort to reduce knee loading and consequent injuries.
