Evaluation of Surface Electromyography Based on Signal Characteristic Change on Exercise Muscle Fatigue

Exercise muscle fatigue is a common muscle fatigue phenomenon in daily life. Related researches have beenwidely applied in ergonomics, rehabilitation medicine, sports science and other fields. At present, many newmethods have been introduced to evaluate muscle fatigue by using sEMG. This paper systematicallysummarized the subjective feeling of muscle fatigue and the objective changes of surface EMG signalcharacteristics and their relationships. Introduced the cyclic dynamic fatigue estimation of muscles underincreasing dynamic motion load and study on the surface EMG signal characteristics of muscle fatigue inducedby static exercise evaluation of the sensitivity and stability of muscle fatigue induced by low-load exercise. Theresults show that there is still a lack of local muscle fatigue evaluation model based on surface EMG, whichcombines fatigue perception and EMG changes. Finally, a more accurate evaluation system of muscle fatigue isproposed.
