摘要

Background and Purpose: Exhausting exercise leads to a gradual decline in the performance of voluntary exercises. This is caused by fatigue which is a complicated phenomenon that can be caused by peripheral and central factors. Continuing to exercise even after feeling tired will result in sports injuries. Therefore, we need to understand how to measure fatigue. It is well-defined that fatigue has peripheral causes such as cardiovascular strain and glycogen depletion, and has already known how to measure peripheral fatigue. Besides, recent literature also focuses on the central causes of fatigue. However, the measurement of central fatigue has not been fully investigated. The purpose of this study was to demonstrate the measurement of central fatigue after exercise. Methods: This systemic review was conducted under the Preferred Reporting Items for Systemic Reviews and Meta-analyses (PRISMA) Guideline. The journal articles were searched electronically using the following databases: PubMed, Scopus, and Web of Science. Peer-reviewed articles published in English until October 2020 were reviewed. To focus on updated studies, this systematic review was limited to published articles in the past 5 years (i.e., 2016, 2017, 2018, 2019, and 2020). The search was undertaken using the following terms to identify potentially relevant studies: ＂neuromuscular OR central OR supraspinal＂ AND ＂fatigue＂ AND ＂sport OR exercise＂. Results: The initial search strategy found 93 references (including duplicates) from the 3 electronic databases. After duplicates were removed, 75 references were assessed by 2 authors. Based on titles and abstracts, 4 manuscripts were considered relevant and the full texts were analyzed. Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of the included observational studies. All of the 4 studies were of good quality. The measurement of central fatigue varied greatly among the included studies. Two studies used transcranial magnetic stimulation (TMS), while others used functional magnetic resonance imaging (fMRI) and electromyography (EMG) to detect central fatigue separately. Conclusion: The results from this review provide the methods that how to measure central fatigue after exercise. In our view, understanding the measurements of central fatigue can avoid sports injuries after doing exercise. Clinical Relevance: Our study provides the information, such as exercise protocol for fatigue and measurement of central fatigue for future studies. This review provides the evidence TMS, fMRI, and EMG that can be used for detecting central fatigue and preventing sports injuries.
