Claim 1:
2. The physical condition determination device according to claim 1,
wherein the heart rate-related index calculation unit comprises:
a frequency-gradient time-series waveform calculation unit which, after finding a frequency time-series waveform from the time-series waveform of the biosignal, finds a frequency-gradient time-series waveform in every predetermined time range from the frequency time-series waveform; and
a distribution ratio time-series waveform calculation unit which extracts, from the frequency-gradient time-series waveform, frequency components belonging to a ULF band to a VLF band corresponding to a function regulation signal having a frequency lower than a frequency at which a fluctuation characteristic of a cardiocirculatory system changes, a fatigue reception signal higher in frequency than the function regulation signal, and an activity regulation signal higher in frequency than the fatigue reception signal, and finds time-series waveforms of distribution ratios of the frequency components.
