: This study investigates inter-limb asymmetry during drop vertical jumps in elite female football players by examining biomechanical variables, such as joint kinematics and ground reaction forces, that are strongly associated with increased anterior cruciate ligament injury risk. : Kinematic and kinetic parameters of 12 football players performing a vertical drop jump from a 30 cm high box were recorded using the Xsens MVN Awinda motion capture system and Vald Force Decks. : The findings revealed significant differences in range of motion between the limbs, particularly in internal/external rotation and dorsiflexion/plantarflexion ( < 0.05). No significant differences were found in abduction/adduction or flexion-extension ROM between limbs during both landing phases. Internal/external rotation range differed significantly during the first landing phase ( < 0.05), but not the second. Hip joint flexion/extension exhibited minimal variation compared to the ankle and knee, with slight increases observed at the hip. From a kinetic standpoint, concentric mean power demonstrated a strong positive correlation with peak power ( = 0.903), underscoring its crucial role in optimizing performance and mitigating injury risk. : The study evaluated biomechanical indicators strongly linked to ACL injury risk. Findings highlight that asymmetrical loading and movement patterns, especially knee valgus and inter-limb discrepancies, may predispose female athletes to non-contact ACL injuries. These results emphasize the need for neuromuscular training interventions targeting symmetry, proprioception, and controlled landing to reduce injury risk and enhance performance.
本研究通过检查与前交叉韧带损伤风险增加密切相关的生物力学变量,如关节运动学和地面反作用力,来调查精英女子足球运动员在垂直纵跳过程中的肢体间不对称性。使用Xsens MVN Awinda运动捕捉系统和Vald Force Decks记录了12名足球运动员从30厘米高的箱子上进行垂直纵跳的运动学和动力学参数。研究结果显示,两下肢在运动范围上存在显著差异,尤其是在内旋/外旋和背屈/跖屈方面(P<0.05)。在两个着地阶段,两下肢在外展/内收或屈伸活动范围方面均未发现显著差异。内旋/外旋范围在第一个着地阶段有显著差异(P<0.05),但在第二个着地阶段没有。与踝关节和膝关节相比,髋关节屈伸的变化最小,仅在髋关节处观察到略有增加。从动力学角度来看,向心平均功率与峰值功率呈强正相关(r=0.903),这突出了其在优化运动表现和降低损伤风险方面的关键作用。本研究评估了与前交叉韧带损伤风险密切相关的生物力学指标。研究结果表明,不对称负荷和运动模式,尤其是膝关节外翻和肢体间差异,可能使女性运动员易发生非接触性前交叉韧带损伤。这些结果强调了需要进行针对对称性、本体感觉和可控着地的神经肌肉训练干预,以降低损伤风险并提高运动表现。
