<b>Biomechanical Effects of Stroboscopic Vision during Crosscut Maneuvers in Elite Football Players</b>

This dataset contains raw and processed biomechanical and electromyographic data collected from twenty elite male football players during standardized crosscut maneuvers under two visual conditions: full vision (FV) and stroboscopic vision (SV). The dataset includes:Three-dimensional kinematic data (joint angles, segmental positions) of the support limb during cutting maneuvers, captured using a marker-based motion capture system;Ground reaction forces (GRFs) in vertical, anteroposterior, and mediolateral directions recorded via force platforms;Surface electromyography (sEMG) signals from key lower-limb muscles (gluteus maximus, rectus femoris, semitendinosus, etc.), including raw signals and normalized pre-activation RMS values;Trial-level metadata indicating condition (FV or SV), task type (dribbling vs. non-dribbling), and participant identifiers;Derived variables used in statistical analysis, including braking velocity, joint angles at initial contact, and muscle activation indices.All data are synchronized and time-normalized relative to initial contact (IC). The dataset supports reproducibility in studies on visual perturbation, perceptual-motor control, and neuromechanical adaptations in sport-specific agility tasks.本数据集汇集了20名精英男子足球运动员在两种视觉条件下完成标准化变向切入动作时采集的原始与处理后的生物力学及肌电数据，两种视觉条件分别为全视野（Full Vision, FV）与频闪视觉（Stroboscopic Vision, SV）。数据集包含以下内容：1. 基于标记式运动捕捉系统采集的变向切入动作中支撑腿的三维运动学数据，涵盖关节角度、节段空间位置；2. 通过测力台记录的垂直、前后及内外侧方向的地面反作用力（Ground Reaction Forces, GRFs）；3. 下肢关键肌肉（臀大肌、股直肌、半腱肌等）的表面肌电（Surface Electromyography, sEMG）信号，包含原始信号与归一化预激活均方根（Root Mean Square, RMS）值；4. 试次级元数据，涵盖视觉条件、任务类型（带球与非带球）以及受试者编号；5. 用于统计分析的衍生变量，包括制动速度、初始接触（Initial Contact, IC）时刻的关节角度以及肌肉激活指数。所有数据均已完成同步，并以初始接触时刻为基准进行时间归一化处理。本数据集可支撑视觉扰动、感知运动控制以及运动专项敏捷任务中神经力学适应相关研究的可重复性工作。
