Abstract: Muscle fatigue is a phenomenon which refers to the decline in the ability of muscles to do work during muscle contraction. It is very common in the process of sports activities, and is one of the main reasons for preventing athletes from improving their performance.Muscle fatigue produces biomarkers that assess muscle fatigue during exercise and the effects of exercise on skeletal muscles.Muscle fatigue is caused by the depletion of nutrients, increased oxidative stress, and activation of inflammatory responses.In addition, it also involves dehydration, high ammonia concentration, mitochondrial biology and genetic reaction, and these reactions can be used to monitor biomarkers of sport fatigue. Through carding, the biomarkers of muscle fatigue are divided into two types: the noninvasive ones mainly including power output measurement, electrophysiological measurement, heart measurement and oxygen uptake, and the invasive ones mainly including biochemical indicators related to ATP metabolism, oxidative stress and inflammation.This paper aims to elaborate the recent research progress of biomarkers of muscle exercise fatigue and provide valuable information for the future diagnosis of exercise fatigue and the development of new biomarkers.

Key words: muscle exercise, muscle fatigue, biomarkers
