NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Research on central fatigue during exercise from 2011 to 2022: A review and bibliometric analysis
ABSTRACT
Background:
Central fatigue expresses as a progressive reduction in voluntary activation or neural drive to the muscle, belong to muscle fatigue, which is due to failure of the central nervous system to excite or drive motoneurons adequately.
Objective:
This study aims to conduct a bibliometric analysis of the field, a detailed review of the current research by CiteSpace and Vos Viewer software.
Methods:
We retrieved the Web of Science Core Collection database from January 1, 2011 to December 31, 2022 about central exercise fatigue related publications. Adopting the method of bibliometric analysis, we tracked research trends and research hotpots currently.
Results:
Through carding the research of central fatigue in neuroscience and pharmacology, a total of 451 central exercise fatigue were published in the past 11 years. France and USA as the most common country of origin. Only 12 organizations issued more than 10 relevant publications. The author with the highest publication volume is Amann European journal of applied physiology published the greatest number of articles. Based on the reference co-citation analysis, a total of 7 major clusters for predominant research topics summarized by clustering high-frequency keywords were explored: supplementation, knee extensors, locomotor exercise, central nervous system, heat stress and transcranial magnetic stimulation.
Conclusions:
We provide a relatively systematic and objective review of the current state of research and important arguments on central exercise fatigue, and finds that hotspots research is focused on four areas: knee extensors, locomotor exercise, heat stress and gender. Furthermore, supplements, the central nervous system and transcranial magnetic stimulation are at the frontier of research. This study provides researchers with valuable guidance in the selection of research topics.
