SPECTRAL ANALYSIS OF SURFACE EMG OF ISOKINETIC VOLUNTARY CONTRACTION UNDER FATIGUE PROTOCOL
Keywords: EMG, spectral analysis, fatigue, muscle
AbstractThe objective of this study was to extract the indices of muscle fatigue from surface electromyographic signal sEMG. Five male subjects participated in the study. . The sEMG of biceps and triceps was measured when subjects performed consecutive right elbow flexion and extension at the required contraction levels until the contraction levels could no longer be maintained. The significant findings of this particular study are that the difference of the mean frequency of sEMG between non-fatigued and fatigued muscle increases with the speed of contraction. This phenomenon has potential for further study.
