背景:在注意力分散的情况下,在五人制足球中进行跳跃和着陆是非接触式前交叉韧带(ACL)损伤的最常见机制之一。神经肌肉训练有效降低了ACL损伤的风险,但是神经认知训练的效果受到的关注较少。这项研究调查了将8周的神经肌肉训练与双重认知任务相结合对具有膝盖韧带优势缺陷的五人制足球运动员的着陆力学的影响。
方法:30名男子五人组运动员(平均±SD:年龄:21.86±3.27岁)有目的地通过收跳试验确定膝关节韧带优势缺损,并随机分为干预组和对照组。干预组进行双任务(DT)训练,每周3次,每次8周,60分钟,对照组只做日常生活活动。在跌落垂直跳跃测试中,评估了初始接触(IC)和完全屈曲(FF)两个时刻的2D着陆运动学。通过2×2重复测量方差分析对数据进行分析,然后在(α≤0.05)的显著性水平进行事后比较(Bonferroni)。
结果:与对照组相比,干预组的动态膝关节外翻在IC(F1,28=6.33;P=0.02,ES=0.31)和FF(F1,28=13.47;P=0.003,ES=0.49)方面有明显改善,膝关节在IC(F1,28=20.08;P=0.001,ES=0.41)和FF(F1,28=13.67;P=0.001,ES=0.32)时屈曲,踝关节背屈在IC(F1,28=37.17;P=0.001,ES=0.72)和FF(F1,28=14.52;P=0.002,ES=0.50),和躯干屈曲在FF(F1,28=20.48;P=0.001,ES=0.59)角度。躯干侧屈曲在IC(F1,28=0.54;P=0.47,ES=0.03)和躯干侧屈曲在IC(F1,28=0.006;P=0.93,ES=0.00)和FF(F1,28=2.44;P=0.141,ES=0.148)角度的变更均无统计学意义。
结论:与对照组相比,DT训练改善了具有膝关节韧带优势缺陷的五人制运动员的着陆力学。

BACKGROUND: The performing of jump and landing in futsal simultaneous with divided attention is one of the most common mechanisms of non-contact anterior cruciate ligament (ACL) injury. Neuromuscular training has effectively reduced the risk of ACL injury, but the effect of neurocognitive training has received less attention. This study investigated the effect of combining 8 weeks of neuromuscular training with dual cognitive tasks on the landing mechanics of futsal players with knee ligament dominance defects.
METHODS: Thirty male futsal players (mean ± SD: age: 21.86 ± 3.27 years) with knee ligament dominance defects were purposefully identified by the tuck jump test and were randomly divided into the intervention and the control group. The intervention group performed dual task (DT) training for three weekly sessions for 8 weeks and 60 min each, while the control group only did activities of daily living. During the drop vertical jump test, 2D landing kinematics in two moments of initial contact (IC) and full flexion (FF) were assessed. Data were analyzed by means of 2 × 2 repeated measures ANOVA followed by post hoc comparison (Bonferroni) at the significance level of (α ≤ 0.05).
RESULTS: A significant improvement was observed in the intervention group compared to the control group for the dynamic knee valgus at IC (F1,28 = 6.33; P = 0.02, ES = 0.31) and FF (F1,28 = 13.47; P = 0.003, ES = 0.49), knee flexion at IC (F1,28 = 20.08; P = 0.001, ES = 0.41) and FF (F1,28 = 13.67; P = 0.001, ES = 0.32), ankle dorsiflexion at IC (F1,28 = 37.17; P = 0.001, ES = 0.72) and FF (F1,28 = 14.52; P = 0.002, ES = 0.50), and trunk flexion at FF (F1,28 = 20.48; P = 0.001, ES = 0.59) angles. Changes in the trunk flexion at IC (F1,28 = 0.54; P = 0.47, ES = 0.03) and trunk lateral flexion at IC (F1,28 = 0.006; P = 0.93, ES = 0.00) and FF (F1,28 = 2.44; P = 0.141, ES = 0.148) angles were not statistically significant.
CONCLUSIONS: DT training compared to the control group improved landing mechanics in futsal players with knee ligament dominance defects.
