Integrated evaluating system for muscle fatigue and muscle force

摘要

The present invention relates to a system and method for evaluating an integrated muscle fatigue and muscle strength, and simultaneously evaluates the fatigue and muscle strength of a human muscle by repeated load application through EMG (electromyography) And to derive an evaluation index by using the evaluation index. In order to accomplish the above object, the present invention provides a measurement apparatus comprising: a measurement unit for measuring and storing a surface EMG signal of a muscle; An average integrated EMG value obtained by dividing the integrated EMG value of each cycle by the execution time of each cycle based on the area of the EMG signal measured by the EMG measuring unit, A time domain analyzer for calculating an increase rate of the electromyogram value; A frequency domain analyzer for generating a frequency spectrum of each cycle by using the electromyogram signal measured through the electromyogram measuring unit, calculating a center frequency value of the generated frequency spectrum, and calculating a reduction rate of the calculated center frequency value; And evaluating the muscle fatigue and muscle strength based on the rate of increase of the mean integrated EMG value and the frequency of the frequency spectrum calculated by the time domain analyzer and the frequency domain analyzer, An evaluation unit for deriving the evaluation index as an evaluation index; .
