In basketball, changing direction is one of the primary mechanisms of anterior cruciate ligament (ACL) injury, often occurring within complex game situations with high cognitive demands. It is unknown how visual attention affects sidestep cutting kinematics during the entire energy absorption phase of the cut in an ecologically valid environment.
The purpose of this research was to study the effect of added cognitive load, in the form of increased visual attentional demands, on sidestep cutting kinematics during the energy absorption phase of the cut in an ecologically valid environment.
Crossover Study.
Fifteen male basketball players (aged 22.1 ± 2.3) performed ten sidestep cutting movements without (BASE) and with (VIS) a visual attention dual task. 3D kinematics of the hip, knee and ankle were recorded utilizing Xsens IMU motion capture. Temporal kinematics were analyzed using Statistical Parametric Mapping. Discrete time point kinematics were additionally analyzed at initial contact (IC) and at peak knee flexion utilizing paired t-tests. Effect sizes were calculated.
Hip flexion was significantly reduced in the VIS condition compared to the BASE condition (p<0.01), including at IC (VIS 35.0° ± 7.2°, BASE 40.7° ± 4.9°, p=0.02, d=0.92) and peak (VIS 37.8° ± 9.7°, BASE 45.5° ± 6.9°, p=0.001, d=0.90). Knee flexion was significantly reduced in the VIS condition, in comparison to the BASE condition (p<0.01), at peak (VIS 59.9° ± 7.5°, BASE 64.1° ± 7.4°, p=0.001, d=0.55).
The addition of visual attention during sidestep cutting altered lower limb kinematics, which may increase ACL injury risk. It is suggested that ACL injury risk screening and prevention should include sidestep cutting with visual attentional demands, in order to mimic the cognitive demands of the sports environment.
在篮球运动中，改变方向是前交叉韧带（ACL）损伤的主要机制之一，通常发生在认知要求较高的复杂比赛情境中。在生态有效环境下，尚不清楚视觉注意力如何影响切入过程中整个能量吸收阶段的侧步切入运动学。
本研究的目的是在生态有效环境下，研究以增加视觉注意力需求形式出现的额外认知负荷对切入能量吸收阶段侧步切入运动学的影响。
交叉研究。
15名男性篮球运动员（年龄22.1±2.3岁）进行了10次侧步切入动作，一次无视觉注意力双重任务（基础状态），一次有视觉注意力双重任务（视觉状态）。使用Xsens IMU运动捕捉系统记录髋、膝和踝关节的三维运动学数据。使用统计参数映射分析时间运动学。在初始接触（IC）和膝关节屈曲峰值时，额外使用配对t检验分析离散时间点运动学。计算效应量。
与基础状态相比，视觉状态下的髋部屈曲显著降低（p<0.01），包括在初始接触时（视觉状态35.0°±7.2°，基础状态40.7°±4.9°，p=0.02，d=0.92）和峰值时（视觉状态37.8°±9.7°，基础状态45.5°±6.9°，p=0.001，d=0.90）。与基础状态相比，视觉状态下膝关节屈曲在峰值时显著降低（p<0.01）（视觉状态59.9°±7.5°，基础状态64.1°±7.4°，p=0.001，d=0.55）。
侧步切入过程中增加视觉注意力会改变下肢运动学，这可能会增加ACL损伤风险。建议ACL损伤风险筛查和预防应包括有视觉注意力需求的侧步切入，以模拟运动环境中的认知需求。
