Incidence rates in anterior cruciate ligament injuries, which are linked to multiple factors, are higher in females than in males. Modifiable contributors to the difference in risk are biomechanical factors such as knee valgus and knee rotation or neuromuscular control. Despite considerable research efforts, re-rupture rates are still high necessitating the need for improved risk reduction and rehabilitation programs. Incorporating exergaming, physically active serious games including a dual-task, has high potential to address this need. However, the execution of dual-tasks leads to altered movement patterns. Consequently, a comprehensive understanding of these movement patterns and their sex-specific differences is essential to subsequently tailor the training approach. The aim of this study was to explore biomechanical differences between males and females when performing a high-intensive exergame. Using three-dimensional motion capture (Vicon) during a 25-min exergame (Sphery Racer, ExerCube), kinematics were measured in 18 healthy athletes (9 male, 9 female). Knee valgus, knee internal rotation, and hip flexion angles during 10-30° knee flexion, were compared between the sexes and in each of the nine different exercises. Touches, and punches showed significant sex differences for knee internal rotation angle (main effect of sex F(1,16) = 6.14, p = .025). Depending on the exercise and side, the difference in estimated means between males and females in touches and punches ranged from 4.6-7.8°, with females showing higher values. Therefore, females display distinct movement patterns linked to anterior cruciate ligament injury, indicating that these movements should be carefully integrated into routine training and late-stage post-injury rehabilitation.
前交叉韧带损伤的发病率与多种因素有关，女性高于男性。导致风险差异的可改变因素包括生物力学因素，如膝外翻、膝关节旋转或神经肌肉控制。尽管进行了大量研究，但再破裂率仍然很高，因此需要改进风险降低和康复计划。将运动游戏（exergaming），即包括双重任务的身体活跃的严肃游戏纳入其中，有很大潜力满足这一需求。然而，双重任务的执行会导致运动模式改变。因此，全面了解这些运动模式及其性别差异对于随后调整训练方法至关重要。本研究的目的是探讨男性和女性在进行高强度运动游戏时的生物力学差异。在一个25分钟的运动游戏（Sphery Racer，ExerCube）过程中使用三维运动捕捉（Vicon），对18名健康运动员（9名男性，9名女性）的运动学进行了测量。比较了两性在10 - 30°膝关节屈曲过程中的膝外翻、膝关节内旋和髋关节屈曲角度，以及九种不同练习中的每一种。触摸和拳击动作在膝关节内旋角度上存在显著的性别差异（性别主效应F(1,16) = 6.14，p = 0.025）。根据练习和侧别，男性和女性在触摸和拳击动作中的估计均值差异在4.6 - 7.8°之间，女性的值更高。因此，女性表现出与前交叉韧带损伤相关的独特运动模式，这表明这些运动应谨慎地纳入常规训练和损伤后期康复中。
