Abstract :
In this paper, electromyographic (EMG) data from long-duration (30-90 minutes), constant-posture, force-varying, fatiguing contractions of the hand were analyzed for trends. Both time (EMG amplitude) and frequency domain (EMG mean power frequency) parameters were tracked. For these long-duration contractions, results found no consistent change in either parameter, even though all subjects continued contractions until exhaustion.
