What is EMG?
EMG is an experimental technique, typically used within human movement assessments and performance monitoring, that involves the recording and analysis of the electrical signals that emanate from the muscles during contractions and force production. By gaining insight into the status of muscular excitation, researchers, clinicians, sports practitioners, and engineers have been able to determine:
The level of muscular effort involved – gained from assessing the overall EMG signal amplitude.
Co-ordination between muscles – assessed by the activation timings of muscles.
The effects of muscle fatigue – an exploration of the frequency component of the EMG signal.
Neural control strategies – how is the brain adapting to training or external stimuli.
