Age-related loss in leg muscle power correlates strongly with segmental bioelectrical impedance spectroscopy (S-BIS). Correlation plots against age for (A) maximum leg muscle power, (B) leg lean mass assessed by dual-energy x-ray absorptiometry (DXA LLM), (C) intracellular resistance (IC) index obtained by S-BIS, and (D) the resistance ratio (R0/RI) by S-BIS in n = 13 men (□) and n = 44 women (●).
