The invention relates to a
muscle strength and
muscle fatigue prediction
algorithm based on surface electromyogram signals, which comprises the following steps of: (1) acquiring the surface electromyogram signals of a measured
muscle area by using a non-invasive sensor, and acquiring muscle
mechanics parameters at the same time; (2) carrying out filtering, amplification and
noise reduction preprocessing on the collected surface electromyogram signals to eliminate interference and enhance
signal quality; and (3) extracting multi-dimensional features from the preprocessed surface electromyogram signals and muscle
mechanics parameters, establishing a
frequency domain data set by using the feature values, and calibrating the muscle
mechanics parameters. The method has the
advantage that the prediction accuracy and reliability are enhanced.
Muscle strength and
muscle fatigue states of different individuals can be reflected more accurately, and accurate prediction of individual differences is realized. The adopted surface electromyogram
signal acquisition mode is non-invasive, and a plug-in
electrode is not needed, so that the test discomfort is reduced, and the acceptability and participation degree of a testee are increased; by establishing an individual model and combining with real-
time signal acquisition, real-time monitoring and prediction of
muscle strength and
muscle fatigue can be realized, and a user can obtain feedback of a muscle state at any time, so that the
exercise intensity, posture and
training plan are adjusted, and the
training effect is optimized.
