Abstract：
Because of population ageing, there will be a vast increase in the prevalence of cognitive decline and dementia. Physical activity and sedentary behaviour have been identified as modifiable lifestyle behaviours associated with these cognitive conditions. Therefore, the aim of this bibliometric analysis is to reveal the knowledge structure of the field of physical activity, sedentary behaviour, and cognitive function among older adults from 2004 to 2024, and to predict emerging research trends. A total of 1290 publications were retrieved from the Web of Science Core Collection. CiteSpace and VOSviewer were applied to conduct performance analysis, science mapping, and enrichment. T. Liu-Ambrose was the most prolific author (39 publications), and the University of British Columbia was the most prolific institution (48 publications). The USA, China, and Canada were the three most productive countries with 392, 174, and 136 publications respectively. Two research trends revealed the knowledge structure of this field, including the shift from evaluating the effectiveness of interventions on cognitive function to evaluating the effectiveness of interventions on other health-related outcomes, as well as an expansion of research on the role of physical activity and sedentary behaviour in the context of healthy ageing. Sleep, sedentary behaviour, and virtual reality may be emerging research trends and may predict directions for future research. Collectively, this bibliometric analysis provides a one-step overview of the knowledge structure in this field for researchers and other stakeholders, as well as a reference for future research.
摘要：
由于人口老龄化,认知能力下降和痴呆的患病率将大幅增加。身体活动和久坐行为已被确定为与这些认知状况相关的可改变的生活方式行为。因此,这种文献计量分析的目的是揭示体育活动领域的知识结构，久坐的行为，2004年至2024年老年人的认知功能，并预测新出现的研究趋势。从WebofScienceCoreCollection检索到总共1,290种出版物。应用CiteSpace和VOSviewer进行性能分析，科学制图,和浓缩。T.Liu-Ambrose是最多产的作者（39种出版物），不列颠哥伦比亚大学是最多产的机构（48种出版物）。美国,中国,加拿大和加拿大是三个生产率最高的国家，分别有392、174和136种出版物。两个研究趋势揭示了该领域的知识结构，包括从评估干预措施对认知功能的有效性转变为评估干预措施对其他健康相关结果的有效性，以及关于身体活动和久坐行为在健康老龄化背景下的作用的研究的扩展。Sleep,久坐的行为，和虚拟现实可能是新兴的研究趋势，并可能预测未来的研究方向。总的来说，此文献计量分析为研究人员和其他利益相关者提供了该领域知识结构的一步概述，为今后的研究提供参考。
