This study aimed to determine the instruction that maximizes fencing attack performance and to explore the sensitivity of a novel efficiency index (EI) that considers reaction time, attack velocity, and absolute error to discriminate between beginners and experienced fencers. Instructions that directed attentional focus internally (react as fast as possible and perform the attack movement as fast as possible) or externally (be as accurate as possible) were provided prior to stimulus presentation. The EI did not differ between the instructions in any group (p > .05), the instructions “react as fast as possible” and “be as accurate as possible” promoted in beginners the highest and the lowest EI, and the EI was higher for fencers. Our findings suggest that the EI could be recommended as a general index of fencing attack efficiency.

这项研究旨在确定使击剑攻击性能最大化的指令，并探索考虑反应时间，攻击速度和绝对误差的新型效率指数（EI）的敏感性，以区分初学者和经验丰富的击剑手。在刺激呈现之前，提供了在内部（尽可能快地反应并尽可能快地执行攻击动作）或在外部（尽可能准确）引导注意力集中的指令。EI在任何组中的指令之间均无差异（p > .05），在初学者中，“最高反应速度”和“最低反应速度”的指导原则是“尽可能快地反应”和“尽可能准确”，而对于击剑运动员来说，该指数则更高。我们的发现表明，EI可被推荐为击剑攻击效率的一般指标。
