运动与线粒体研究进展--基于Citespace知识图谱的可视化分析

Research Progress in Exercise and Mitochondrial--Visual Analysis Based on CiteSpace Mapping Knowledge Domain

目的:揭示国内外运动与线粒体研究领域近五年刊文的发文总量、核心群体、研究主题等规律,为学者发文提供参考依据。方法:通过运用文献计量学方法对运动与线粒体2018-2022年的论文进行筛查,然后分别从论文发文量、机构及主题和热点三个方面进行统计和分析。结果发现:①在发文量方面,近五年来国内外运动与线粒体发文总量具有稳定的趋势,从目前来看,国外每年发文量是国内的5倍多。②在作者和机构方面,国内外发文量前十名的作者发文总量差别不大,机构的发文量相差两倍左右,国内科研机构主要分布在体育类专业院校,国外研究主要分布在综合类院校和医科大学。从聚类分析看,相比于国内来说国外的节点连线更加密集,作者与作者、机构与机构之间有更高的合作率,学术氛围更加浓厚。③在关键词方面,国内擅长于开展运动、线粒体、骨骼肌的研究,国外擅长于开展机制、生理功能整体类研究。在应用研究领域,国内注重于精神类疾病,而国外注重于肥胖类疾病。④最近一年来国内外新出现的关键词都在减少,可能和体育是一门交叉类学科有关,该领域的发展与进步需要医学、化学、生物领域共同突破一些研究难点得以实现,以此使得在能量的去向以及线粒体分泌物作用方面的研究可以更加深入。

OBJECTIVE:The aim of the paper is to disclose the rules of the total number,core groups,and research topics of published articles in the research domain of exercise and mitochondrial at home and abroad in the past five years,and to improve the theoretical reference for scholars to publish articles.METHODS:By using the methods of bibliometrics,the papers on sports and mitochondria from 2018 to 2022 were screened,and then a statistical analysis was performed on the following three aspects of these papers:the number of papers published,institutions,topics and hot issues.The results reveal that:(1)In terms of the number of published papers,domestic and foreign publications on exercise and mitochondrial has been stable in the total number over the past five years.At present,the annual quantity of papers published abroad is more than 5 times that of domestic ones.(2)As for authors and institutions,there is little difference in the total number of papers published by the top ten authors at home and abroad,but the total number of papers published by institutions are about twice different.Domestic scientific research institutions are mainly sports colleges and universities,whereas foreign papers were mainly published by comprehensive colleges and universities and medical universities.A cluster analysis disclosed that in contrast,connection lines among foreign papers are more dense,indicating higher author cooperation rate and higher institutional cooperation rate,as well as stronger academic atmosphere.(3)With respect to keywords,the domestic researchers are good at research on exercise,mitochondria,and skeletal muscle,and the foreign papers are more on overall research such as mechanisms and physiological functions.In the domain of applied research,the domestic papers focus on mental illnesses,whereas the foreign papers focus on obesity related diseases.(4)The past year has witnessed fewer new keywords in both domestic and foreign papers,which may be attributed to the fact that sports science is an interdisciplinary subject.The advancement and progress in sports science requires joint efforts and breakthroughs in the fields of medicine,chemistry and biology,so as to enable more in-depth studies of energy flow and the role of mitochondrial secretion.
