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.
本研究旨在确定最大限度提高击剑攻击表现的指导，并探讨一种新的效率指数（EI）的敏感性，该指数考虑反应时间、攻击速度和绝对误差，以区分初学者和经验丰富的击剑运动员。在刺激呈现之前，提供了将注意力集中在内部（尽可能快地反应并尽可能快地执行攻击动作）或外部（尽可能准确）的指导。在任何组中，指令之间的 EI 都没有差异（p >.05），对于初学者，“尽可能快地反应”和“尽可能准确”的指令促进了最高和最低的 EI，而 EI 对于击剑运动员来说更高。我们的研究结果表明，EI 可以作为击剑攻击效率的一般指标推荐。
