Surface EMG spectral analysis as an indicator of fatiguing factors during dynamic sports related movements

  • Anthony James Murphy

Student thesis: Doctoral Thesis


During fatiguing exercise, which for the purpose of this study was defined as exercise which significantly reduces peak muscle force capacity, the components of surface EMG have been noted to shift to a lower frequency spectrum. In the literature this effect has predominantly been studied during isometric contraction to maintain the stationarity of the EMG signal. It has been speculated whether this phenomenon is a result of centrally mediated neurological response to exercise or as a result of the local muscle environment. This thesis was designed to examine the effect of exercise induced fatigue on surface EMG spectral analysis during dynamic exercise.
