虚拟现实越来越多地应用于支持体育训练和提高运动员的运动成绩。然而，有一个研究缺陷，特别是在武术，它还没有被证明在多大程度上的反应行为的运动员在虚拟现实中是相同的，在真实的世界。如果这一点得到证实，VR适应技能的转移到RW可以预期和运动训练在虚拟环境中可以应用，以提高运动成绩。由于反应行为是必不可少的许多体育运动，本研究比较了它在空手道运动的竞争重要的攻击（Kizami-Zuki）的一个真实的和一个虚拟的对手。有经验的空手道运动员戴着一个头戴式显示器，并被要求对22次空手道攻击做出快速有效的反应，其中8次是Kizami Zuki的攻击。使用基于视频的运动评估，空手道专家量化的响应行为的参数“响应时间”，“响应质量”和“响应的种类”。结果显示，在两种条件（虚拟现实与真实的世界）之间的“反应时间”和“反应类型”没有显着差异。只有“响应质量”在真实的世界中比在虚拟现实中被评为更好。结果表明，空手道运动员在虚拟现实中的“反应时间”和“反应类型”与真实的世界中的反应时间和反应类型相似。
Virtual reality is increasingly applied to support physical training and improve athletes’ performance in sports. Nevertheless, there is a research deficit in that, especially in martial arts, it has not yet been shown to what extent the response behavior of athletes in virtual reality is the same as in the real world. If this can be confirmed, a transfer of VR-adapted skills to RW can be expected and sports training in a virtual environment can be applied to improve sports performance. Since the response behavior is essential for many sports, this study compares it in karate kumite to the competition-important attack (Kizami-Zuki) of a real and a virtual opponent. Experienced karate athletes wore a head-mounted display and were asked to respond quickly and efficiently to 22 karate attacks, of which eight were Kizami Zuki’s attacks. Using a video-based movement assessment, karate experts quantified the response behavior with the parameters ‘time for response’, ‘response quality’ and ‘kind of response’. Results show no significant differences in ‘time for response’ and ‘kind of response’ between both conditions (virtual reality vs. real world). Only the ‘response quality’ was rated better in real world than in virtual reality. It is concluded that the ‘time of response’ and ‘kind of response’ for karate kumite athletes in virtual reality are similar to that in the real world.
