PROBLEM TO BE SOLVED: To provide: a method and apparatus for extracting an anaerobic threshold indicating a time when muscle fatigue occurs by using an electromyography signal; and a heart rate extraction apparatus and an exercise information providing apparatus that use the same.SOLUTION: An anaerobic threshold extraction apparatus comprises: an electromyography (EMG) signal acquirer configured to acquire an EMG signal; and an anaerobic threshold extractor configured to extract an anaerobic threshold indicating a time when user muscle fatigue occurs on the basis of a change in the EMG signal.SELECTED DRAWING: Figure 1
