The aim of this study was to examine whether target width and target distance influence the planning phase of a fencing lunge (early and anticipatory postural adjustments) as well as the execution phase of a fencing lunge. Eight elite female fencers participated in the study. The displacement of the center of foot pressure, muscle activity of the tibialis anterior, and kinematics of center of mass were recorded using force plates. The results show that target width and distance have no effect on early and anticipatory postural adjustments as well as the acceleration and velocity of the center of mass at the moment of foot-off. However, a greater target distance was associated with a greater max center of mass acceleration and velocity, and larger target width resulted in a greater max center of mass acceleration during lunging (p < 0.05). We suppose that the effect of task parameters on preparing a fencing lunge may be mitigated due to the specific technique adopted by expert fencers and the ballistic nature of a fencing lunge.
本研究的目的是检验目标宽度和目标距离是否会影响击剑弓步的准备阶段（早期和预期姿势调整）以及击剑弓步的执行阶段。八名精英女子击剑运动员参与了该研究。使用测力板记录足底压力中心的位移、胫骨前肌的肌肉活动以及质心的运动学数据。结果表明，目标宽度和距离对早期和预期姿势调整以及离地瞬间质心的加速度和速度没有影响。然而，更大的目标距离与更大的质心最大加速度和速度相关，更大的目标宽度导致弓步过程中质心最大加速度更大（p < 0.05）。我们推测，由于专业击剑运动员采用的特定技术以及击剑弓步的弹道性质，任务参数对准备击剑弓步的影响可能会减轻。
