Extended reality technologies (e.g. virtual reality (VR), augmented reality (AR) and mixed reality (MR)) are gaining popularity in sports owing to their unique advantages. This study aims to analyse the progress of the application of extended reality technology in sports and reveal its cooperative features, research hotspots and development trends.
We searched the literature in the Web of Science Core Collection (WoSCC) database within the period 2000 to 2021 and conducted a bibliometric analysis. The analysis methods included statistical, co-occurrence, hierarchical clustering and social network analyses.
A total of 340 articles were gathered. The literature related to its research showed an increasing trend over time. The paper collaboration rate was 90.88% (309/340 papers), and the degree of author collaboration was 3.96 (1345/340). was found to be the most productive journal, and Queen's University Belfast was the most productive institution. The United States, China and the United Kingdom were the three main contributors to the field. The foundational themes in sports extended reality research were (i) sports games and extended reality systems, (ii) virtual simulation devices and artificial intelligence, (iii) sports training and performance and (iv) age-appropriate physical activity, sports rehabilitation and physical education.
The level of author collaboration was low, but the degree of author collaboration is largely on the rise. The closeness of the collaboration between institutions and countries was also low. In addition, the subject of sport extended reality is relatively fragmented. Therefore, more research is needed to strengthen it in the future.
扩展现实技术（如虚拟现实（VR）、增强现实（AR）和混合现实（MR））因其独特优势在体育领域越来越受欢迎。本研究旨在分析扩展现实技术在体育领域的应用进展，并揭示其合作特征、研究热点和发展趋势。
我们检索了2000年至2021年期间Web of Science核心合集（WoSCC）数据库中的文献，并进行了文献计量分析。分析方法包括统计分析、共现分析、层次聚类分析和社会网络分析。
共收集到340篇文章。与其相关的研究文献随时间呈增长趋势。论文合作率为90.88%（309/340篇论文），作者合作度为3.96（1345/340）。发现《》是发文量最多的期刊，贝尔法斯特女王大学是发文量最多的机构。美国、中国和英国是该领域的三大主要贡献者。体育扩展现实研究的基础主题包括：（i）体育游戏与扩展现实系统；（ii）虚拟仿真设备与人工智能；（iii）运动训练与表现；（iv）适龄体育活动、运动康复与体育教育。
作者合作水平较低，但作者合作度总体呈上升趋势。机构和国家之间的合作紧密程度也较低。此外，体育扩展现实主题相对分散。因此，未来需要更多研究来加强这方面的研究。 （注：原文中“ was found to be the most productive journal”处“《》”表示此处原文有缺失期刊名信息）
