An electromyographic signal acquisition method and apparatus applicable to the technical field of wearable electronic devices. The electromyographic signal acquisition method comprises: controlling an acquisition module in a wearable apparatus to measure electromyographic signals at preset body positions at a first acquisition frequency corresponding to a normal mode (S101); obtaining the strength of the electromyographic signals, and determining whether the strength is less than a first preset threshold (S102); and if yes, controlling the acquisition module to operate in an energy-saving mode, and controlling the acquisition module to measure the electromyographic signals at the preset body positions at a second acquisition frequency corresponding to the energy-saving mode, wherein the second acquisition frequency is lower than the first acquisition frequency (S103). The electromyographic signal acquisition method and apparatus enable a wearable apparatus to distinguish unconscious behavior movements from normal training movements. In a non-exercise training state, by controlling an acquisition module to measure electromyographic signals at an acquisition frequency corresponding to an energy-saving mode, the acquisition frequency is reduced, the acquisition quantity of invalid electromyographic signals is decreased, and the effectiveness of electromyographic signal acquisition is improved.
