Global aging has increased the importance of health management in older adults. Exercise is a crucial strategy for healthy aging and has led to numerous scientific advancements due to its impact on age-related illnesses. We aim to investigate the research hotspots, bursts of knowledge base, and trends in the field of exercise and physical activity in older adults over the past decade and present them in a visual manner.
We searched and retrieved data from the Web of Science database, and performed a bibliometric analysis of publications on exercise and physical activity research in older adults from 2013 to 2022. We evaluated the current status and hotspots through co-occurrence analysis using VOSviewer. The evolution and bursts of knowledge base were assessed through co-citation analysis using CiteSpace. Thematic evolution was analyzed using the bibliometrix package to discover keyword trends. The attribution and collaboration of countries/regions, institutions and authors were also analyzed.
A total of 27,820 publications were included. Publications on exercise and physical activity in older adults increased from 1755 records in 2013-3737 records in 2022 annually. In co-occurrence analysis of keywords, 5 major clusters were revealed: sarcopenia, cognition, frailty, mental health, and rehabilitation. Co-citation analysis reveals that the knowledge base has evolved from references focused on frailty, dementia, and physical activity before 2016 to references focus on sarcopenia, cognition and sedentary behavior after 2020. Among the top 10 high-frequency keywords, sarcopenia demonstrated a consistent and significant upward trend, with its percentage increasing from 8.7 % (82 times) in 2016 to 12.2 % (236 times) in the most recent year, making it the most frequently used keyword. Frailty ranked second, starting at 5.6 % (41 times) in 2013 and gradually rising to 11.7 % (225 times) in 2022. The most productive country, institution and author were the USA (8212 publications), the University of Pittsburgh(501 publications), and Brendon Stubbs(94 publications), respectively.
Publications on exercise and physical activity for older adults have surged in the last decade, accompanied by a shift in the knowledge base. Regional disparities in the academic output in this field need to be addressed in the future to promote healthy aging.
全球老龄化增加了老年人健康管理的重要性。运动是健康老龄化的关键策略，因其对与年龄相关疾病的影响而带来了众多科学进展。我们旨在调查过去十年老年人运动与身体活动领域的研究热点、知识库的爆发情况及趋势，并以可视化方式呈现。
我们从科学网数据库搜索并检索数据，对2013年至2022年关于老年人运动与身体活动研究的出版物进行文献计量分析。我们使用VOSviewer通过共现分析评估现状和热点。通过使用CiteSpace的共被引分析评估知识库的演变和爆发情况。使用bibliometrix包分析主题演变以发现关键词趋势。还分析了国家/地区、机构和作者的归属及合作情况。
共纳入27,820篇出版物。关于老年人运动与身体活动的出版物每年从2013年的1755条记录增加到2022年的3737条记录。在关键词共现分析中，揭示了5个主要聚类：肌肉减少症、认知、衰弱、心理健康和康复。共被引分析表明，知识库已从2016年前侧重于衰弱、痴呆和身体活动的参考文献，演变为2020年后侧重于肌肉减少症、认知和久坐行为的参考文献。在十大高频关键词中，肌肉减少症呈现持续且显著的上升趋势，其百分比从2016年的8.7%（82次）增加到最近一年的12.2%（236次），成为使用最频繁的关键词。衰弱排名第二，从2013年的5.6%（41次）开始，逐渐上升到2022年的11.7%（225次）。产出最多的国家、机构和作者分别是美国（8212篇出版物）、匹兹堡大学（501篇出版物）和布伦登·斯塔布斯（94篇出版物）。
过去十年关于老年人运动与身体活动的出版物激增，同时知识库发生了转变。该领域学术产出的地区差异未来需要得到解决，以促进健康老龄化。
