METHOD AND APPARATUS FOR EXTRACTING ANAEROBIC THRESHOLD, AND HEART RATE EXTRACTION APPARATUS AND EXERCISE INFORMATION PROVIDING APPARATUS THAT USE THE SAME
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【課題】筋電図信号を用いて筋肉疲労が発生する時点を示す無酸素的閾値を抽出する方法及び装置、並びにこれを用いた心拍数抽出装置及び運動情報提供装置を提供する。【解決手段】本発明の無酸素的閾値抽出装置は、筋電図（ＥｌｅｃｔｒｏＭｙｏＧｒａｐｈｙ：ＥＭＧ）信号を取得する筋電図信号取得部と、筋電図信号の変化に基づいてユーザの筋肉疲労が発生する時点を示す無酸素的閾値を抽出する無酸素的閾値抽出部と、を備える。【選択図】図１
