sEMG Signal Changes of the Biceps during Dynamic Isokinetic Voluntary Contractions

The purpose of this study was to determine the sEMG signal characteristics of biceps during dynamic isokinetic voluntary contractions and to select a more effective sEMG indices for muscle functional level prediction .The results showed both iEMG and RMS did not significantly increased and had no relationship with endurance time; Both MPF and MF decreased significantly with only MPF had good relationship with endurance time; The slope of MPF had a significant negative relationship with total muscle work and therefore be regarded as a good predictor of dynamic muscle function.
