PROBLEM TO BE SOLVED: To provide a fatigue degree meter for quantifying a fatigue degree of a subject from objective data which is acquired by a simple measurement, and which allows a subject to grasp whether or not, a temporary factor which affects a measurement result has occurred during measurement.SOLUTION: A fatigue degree meter 2 comprises: a detection part 14 for detecting a biological signal of a subject related to a circulatory organ, continuously in a certain period a storage part 15 for storing a correspondence between an index related to a heart beat and an index related to a fatigue degree a heart rate calculation part 24 for calculating time series data of a heart rate of the subject based on the detected biological signal a fatigue degree determination part for determining a fatigue degree of the subject by referring to the correspondence based on the heart beat information acquired from the detected biological signal an abnormality determination part 27 for determining whether or not, the time series data indicates a predetermined type of abnormal variation and an output part for outputting determination results of the fatigue degree determination part and the abnormality determination part.SELECTED DRAWING: Figure 16COPYRIGHT: (C)2017,JPO&INPIT【課題】簡易な測定により得られた客観的なデータから被測定者の疲労度を定量化するとともに、測定結果に影響を与え得る一時的な要因が測定時に発生したか否かを被測定者が把握可能な疲労度計を提供する。【解決手段】疲労度計2は、循環器に関する被測定者の生体信号を一定時間連続して検知する検知部14と、心拍に関する指標と疲労度に関する指標との対応関係を記憶する記憶部15と、検知された生体信号から被測定者の心拍数の時系列データを算出する心拍数算出部24と、検知された生体信号から得られる心拍情報に基づき対応関係を参照して被測定者の疲労度を判定する疲労度判定部と、予め定められた類型の異常な変動を時系列データが示しているか否かを判定する異常判定部27と、疲労度判定部および異常判定部による判定結果を出力する出力部とを有する。【選択図】図16
