Abstract
To evaluate the capability of C(n) and %DET(determinism%) together with the linear indices,nine female subjects took part in the non-fatigue ergometer cycling exercise.The sEMG signal changes were detected simultaneously of their quadriceps femoris to analyze its changes of the linear indices AEMG,MPF and the non-linear indices C(n),%DET.The linear index AEMG inclined linearly while MPF leveled off with the increasing of the force.Except %DET changed in 100 W and 175 W,the non-linear index C(n) and %DET inclined both leveled off with the increasing of the power.Therefore,the linear index AEMG together with the non-linear indices C(n) and %DET have a certain sensitivity in the Force-SEMG relationship during dynamic exercises.
