要約(英語): It has been theoretically predicted that the skeletal muscles show peculiar frequency-dependence of the electrical impedance between 1 Hz and 100 Hz; the resistance increases with frequency and the reactance becomes positive. In such low frequency-region, experimental results have not been reported, and instruments for use in the bioelectrical impedance analysis are not commercially available, at this stage. In this study, measurements of the impedance of a test circuit consisting of capacitors and resistors were carried out by the four-terminal method using an instrument for electrochemical measurements (PARSTAT 3000A, Princeton Applied Research) in a frequency-region from 0.1 Hz to 1 MHz in galvanostatic mode in which the amplitudes of the applied current were 100 μA (rms) and below, that met the safety standard JIS T0601-1. When the amplitudes of the applied current were between 100 and 30 μA (rms), observed values of resistance and reactance were in good agreement with theoretical ones from 0.1 Hz to 100 kHz. The capacitance and conductance agreed with theoretical ones below 30 kHz and below 3 kHz, respectively. These results suggest that the instrument is available for the bioelectrical impedance analysis down to the low-frequency region under the condition required by the safety standard.
