Fatigue induced by soccer playing increases physical efforts, which might alter the transverse knee stability, a known factor that promotes knee injuries, particularly anterior cruciate ligament injury. Thereby, primarily, we aimed to determine whether rotatory knee stability decreases immediately following a competitive soccer match in amateur players. Furthermore, we assessed the role of the preferred and non-preferred limbs to kick a ball in rotatory knee stability and the correlation between performance parameters and rotatory knee stability. We hypothesized that the knee stability decreases immediately after a competitive soccer match in amateur players. Eight healthy amateur soccer players (aged 27.2 ± 4.7 years and with body mass index of 23.8 ± 1.2 kg m) were included immediately before and after a competitive soccer match. The rotatory knee stability was assessed in the preferred and non-preferred limbs through the acceleration and jerk of the pivot shift maneuver and by the internal knee rotation of a pivoting landing task. Two-way repeated-measures ANOVA for factors time (before and after the soccer match) and limb (preferred and non-preferred) and multiple comparisons were performed using = 5%. There was a statistical significance for the main factor time in the acceleration (5.04 vs. 6.90 ms, Δ = 1.86 ms, = 0.020, η = 0.331) and jerk (18.46 vs. 32.10 ms, Δ = 13.64 ms, = 0.004, η = 0.456) of the pivot shift maneuver. Rotatory stability decreases following a competitive soccer match in amateur soccer players under fatigue. Both the acceleration and jerk during the pivot shift maneuver is increased without significant internal knee rotation changes during the pivoting landing task.
足球运动引起的疲劳会增加体力消耗，这可能会改变膝关节的横向稳定性，而横向稳定性是导致膝关节损伤（尤其是前交叉韧带损伤）的一个已知因素。因此，我们的主要目的是确定业余球员在一场足球比赛后膝关节旋转稳定性是否会立即下降。此外，我们评估了在膝关节旋转稳定性方面，惯用腿和非惯用腿在踢球时的作用，以及运动表现参数与膝关节旋转稳定性之间的相关性。我们假设业余球员在一场足球比赛后膝关节稳定性会立即下降。八名健康的业余足球运动员（年龄27.2±4.7岁，体重指数23.8±1.2 kg/m）在一场足球比赛前后即刻被纳入研究。通过轴移动作的加速度和急动度以及旋转落地任务中的膝关节内旋，对惯用腿和非惯用腿的膝关节旋转稳定性进行评估。对时间（足球比赛前后）和肢体（惯用腿和非惯用腿）两个因素进行双向重复测量方差分析，并使用α = 5%进行多重比较。在轴移动作的加速度（5.04对6.90 ms，Δ = 1.86 ms，P = 0.020，η = 0.331）和急动度（18.46对32.10 ms，Δ = 13.64 ms，P = 0.004，η = 0.456）方面，主要因素时间存在统计学意义。在疲劳状态下，业余足球运动员在一场足球比赛后旋转稳定性下降。在旋转落地任务中，轴移动作期间的加速度和急动度均增加，而膝关节内旋无明显变化。
