Abstract

The purpose of this study was to examine the shift characteristics of sEMG signal and to identify some sEMG predictors of muscle functional level. All subjects performed muscle isometric loading test. The results showed that 1) both rate of MF and MPF decline showed a linear type decrease; 2) both MF, MPF decline rate have a significant correlation to endurance time. In conclusion, MF and MPF decline rate used in present study were a reliable noninvasive predictor of muscle functional level.
