%0 Journal Article %T Fatigue-Induced Cole Electrical Impedance Model Changes of Biceps Tissue Bioimpedance %A Bo Fu %A Todd J. Freeborn %J - %D 2018 %R https://doi.org/10.3390/fractalfract2040027 %X Abstract Bioimpedance, or the electrical impedance of biological tissues, describes the passive electrical properties of these materials. To simplify bioimpedance datasets, fractional-order equivalent circuit presentations are often used, with the Cole-impedance model being one of the most widely used fractional-order circuits for this purpose. In this work, bioimpedance measurements from 10 kHz to 100 kHz were collected from participants biceps tissues immediately prior and immediately post completion of a fatiguing exercise protocol. The Cole-impedance parameters that best fit these datasets were determined using numerical optimization procedures, with relative errors of within approximately ¡À 0.5 % and ¡À 2 % for the simulated resistance and reactance compared to the experimental data. Comparison between the pre and post fatigue Cole-impedance parameters shows that the R ¡Þ , R 1 , and f p components exhibited statistically significant mean differences as a result of the fatigue induced changes in the study participants.
