Table_7_Research hotspots and new trends in the impact of resistance training on aging, bibliometric and visual analysis based on CiteSpace and VOSviewer.pdf

PurposeResistance training (RT) can intervene in aging, which can effectively improve trainees’ life. However, unhealthy living habits such as irregular life, obesity and hyperlipidemia, and chronic diseases lead to a significant decline in the energy level of the population, seriously affecting the health of the population. Our research identifies the research hotspots of RT to intervene in aging from the perspective of bibliometrics, predicts research frontiers and development trends, and provides more perspectives for research on aging populations.
MethodsIn this study, we used CiteSpace and VOSviewer visualization software to draw the scientific knowledge map of countries/regions, institutions, authors, co-occurrence keywords, and co-cited references of published articles, and explore the Web of Science core collection database all about the RT intervention aging research status, hotspots, frontiers, and development trends of articles on aging.
ResultsAmong the 760 articles that meet the inclusion criteria, the number of articles published and the frequency of citations have increased steadily in the past 5 years. Judging from the countries/regions, institutions, scholars, and journals that published articles, the ones with the largest numbers are the USA, Univ Estadual Londrina, Cyrino ES, and Exp Gerontol. The ones with the highest influence are England, Univ Arkansas Med Sci, Frontera WR, and Biochem Biophys Rep Co. The top five co-occurrence keywords of include exercise, strength, resistance training, skeletal muscle, and muscle strength. The research frontier is physical function.
ConclusionIn the field of RT intervention aging research, relevant scholars deserve further in-depth research and exploration. The United States, Brazil, Canada, and other economically developed countries/regions, institutions, and authors have greater influence and productivity. These quantitative research results can provide references for relevant scholars’ follow-up research and government departments to formulate and modify health policies or measures.

一、研究目的
抗阻训练（Resistance Training, RT）可干预衰老进程，有效提升受训者的生活品质。然而，生活不规律、肥胖、高脂血症等不良生活习惯以及慢性病，会导致人群整体能量水平显著下降，严重威胁民众健康。本研究从文献计量学视角，明确抗阻训练干预衰老领域的研究热点，预测该领域的研究前沿与发展趋势，为衰老人群相关研究提供更多研究视角。

二、研究方法
本研究采用CiteSpace与VOSviewer两款可视化分析软件，绘制已发表文献的国家/地区、科研机构、作者、共现关键词及共被引参考文献的科学知识图谱，并依托Web of Science核心合集数据库，全面探究抗阻训练干预衰老相关文献的研究现状、热点、前沿及发展趋势。

三、研究结果
在符合纳入标准的760篇文献中，近5年的发文量与被引频次均呈稳步增长态势。从发文主体来看，发文量位居前列的国家/地区、机构、学者及期刊分别为美国、隆德里纳州立大学（Univ Estadual Londrina）、西里诺 ES（Cyrino ES）及《实验老年学》（Exp Gerontol）；影响力最高的主体则为英国、阿肯色大学医学科学中心（Univ Arkansas Med Sci）、弗龙特拉 WR（Frontera WR）及《生物化学与生物物理学报告》（Biochem Biophys Rep Co）。共现关键词排名前五的依次为运动、肌力、抗阻训练、骨骼肌及肌肉力量，当前研究前沿为身体功能。

四、研究结论
在抗阻训练干预衰老研究领域，相关学者仍需开展更为深入的研究与探索。美国、巴西、加拿大等经济发达国家/地区的科研机构与学者具备更强的学术影响力与研究产出能力。本研究的量化分析结果可为相关学者的后续研究，以及政府部门制定、调整健康政策与举措提供参考依据。
