Dynamic, interactive sports require athletes to identify, pick-up and process relevant information in a very limited time, in order to then make an appropriate response. Perceptual-cognitive skills are, therefore, a key determinant of elite sporting performance. Recently, sport scientists have investigated ways to assess and train perceptual-cognitive skills, with one such method involving the use of blurred stimuli. Here, we describe the two main methods used to generate blur (i.e., dioptric and Gaussian) and then review the current findings in a sports context. Overall, it has been shown the use of blur can enhance performance and learning of sporting tasks in novice participants, especially when the blur is applied to peripheral stimuli. However, while intermediate and expert level participants are relatively impervious to the presence of blur, it remains to be determined if they are positive effects on learning. In a final section, we describe some of the methodological issues that limit the application of blur and then discuss the potential use of virtual reality to extend the current research base in sporting contexts.
动态、交互式运动要求运动员在非常有限的时间内识别、获取并处理相关信息，以便随后做出适当反应。因此，感知认知技能是精英运动表现的关键决定因素。最近，运动科学家们研究了评估和训练感知认知技能的方法，其中一种方法涉及使用模糊刺激。在此，我们描述了用于产生模糊的两种主要方法（即屈光和高斯模糊），然后回顾了在体育背景下的当前研究结果。总体而言，研究表明，使用模糊可以提高新手参与者的运动任务表现和学习效果，尤其是当模糊应用于周边刺激时。然而，虽然中级和专家级参与者对模糊的存在相对不敏感，但模糊对他们学习是否有积极影响仍有待确定。在最后一部分，我们描述了一些限制模糊应用的方法学问题，然后讨论了虚拟现实在体育背景下扩展当前研究基础的潜在用途。
