SVM-based motion estimation and muscle fatigue evaluation using myoelectric center frequency

Previous studies have shown that the center frequency of myoelectricity transitions from the high-frequency band to the low-frequency band with muscle fatigue, and this is one of the evaluation indices of muscle fatigue. However, if there is more than one type of movement in the exercise with muscle fatigue, the transition of the center frequency becomes irregular, making it difficult to evaluate fatigue. In this study, we will perform motion estimation using SVM and observe how the transition of the center frequency changes by extracting only the muscle potential of a single movement in an exercise.
