Plantar pressure characteristics during fencing movements may provide more specific information about the influence of foot loading on overload injury patterns. Twenty-nine experienced fencers participated in the study. Three fencing-specific movements (lunge, advance, retreat) and normal running were performed with three different shoe models: Ballestra (Nike, USA), Adistar Fencing Lo (Adidas, Germany), and the fencers' own shoes. The Pedar system (Novel, Munich, Germany) was used to collect plantar pressures at 50 Hz. Peak pressures, force-time integrals and contact times for five foot regions were compared between four athletic tasks in the lunge leg and supporting leg. Plantar pressure analysis revealed characteristic pressure distribution patterns for the fencing movements. For the lunge leg, during the lunge and advance movements the heel is predominantly loaded; during retreat, it is the hallux. For the supporting leg, during the lunge and advance movements the forefoot is predominantly loaded; during retreat, it is the hallux. Fencing-specific movements load the plantar surface in a distinct way compared with running. An effective cushioning in the heel and hallux region would help to minimize foot loading during fencing-specific movements.
击剑运动中足底压力特征可提供关于足部负荷对过度负荷损伤模式影响的更具体信息。29 名经验丰富的击剑运动员参与了本研究。使用三种不同鞋型（Ballestra（美国耐克）、Adistar Fencing Lo（德国阿迪达斯）和运动员自己的鞋）进行了三种特定于击剑的运动（弓步、前进、后退）和正常跑步。Pedar 系统（德国慕尼黑 Novel）以 50 Hz 的频率采集足底压力。比较了弓步腿和支撑腿在四个运动任务中的五个足区的峰值压力、力-时积分和接触时间。足底压力分析揭示了击剑运动的特征压力分布模式。对于弓步腿，在弓步和前进运动中，脚跟主要承受负荷；在后退运动中，大脚趾承受负荷。对于支撑腿，在弓步和前进运动中，前脚掌主要承受负荷；在后退运动中，大脚趾承受负荷。与跑步相比，击剑特有的运动方式以一种独特的方式加载足底表面。在脚跟和大脚趾区域提供有效的缓冲，将有助于最大限度地减少击剑特有的运动中足部的负荷。
