Abstract

Video analyses of ACL injury situations in change-of-direction tasks suggest an elevated injury risk during flatfooted or rearfoot landing. While loading in each individual plane of the knee can contribute to injury, combined loading seems to be the most likely mechanism. This study investigated if knee joint moments are related to the foot strike angle in pre-planned and unplanned handball-specific sidestep cuts performed by n = 51 female handball players. Canonical correlation analysis (CCA) with the foot strike angle at initial ground contact serving as the predictor variable was performed on the knee joint moment vector field (M_xyz). In both conditions, the foot strike angle was related to M_xyz. Subsequently, post-hoc tests were conducted using CCA for moment couples (M_xy, M_xz, M_yz) and linear regression for individual moment components. Results revealed that traditional analyses focusing on individual planes only partially explain the observed relationships, particularly during the unplanned cutting condition. Given the time periods in which correlations exist, this study shows that manipulating the foot strike angle has the potential to reduce multi-plane knee loading associated with ACL injury, while limiting analyses to individual planes might underestimate the potential to mitigate ACL injury risk.

足击角作为侧步切割中多平面膝关节力矩的关键预测因子：对前交叉韧带损伤预防的影响。

在改变方向的任务中，前交叉韧带损伤情况的视频分析表明，在平足或后脚着地时，损伤风险增加。虽然膝关节各平面的负荷都可能导致损伤，但联合负荷似乎是最可能的机制。本研究调查了51名女子手球运动员在预计划和非计划手球侧身切动作中，膝关节力矩是否与足部击球角度有关。对膝关节力矩矢量场（Mxyz）进行典型相关分析（CCA），以初始接触地面时足部触地角度作为预测变量。在这两种情况下，足击角都与Mxyz有关。随后，使用CCA对矩对（Mxy, Mxz, Myz）进行事后测试，并对单个矩分量进行线性回归。结果表明，传统的分析侧重于单个平面，只能部分解释观察到的关系，特别是在计划外切削条件下。考虑到相关性存在的时间周期，本研究表明，操纵足部打击角度有可能减少与前交叉韧带损伤相关的多平面膝关节负荷，而将分析限制在单个平面可能低估了减轻前交叉韧带损伤风险的潜力。

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
