Figure 1: Abdominal bioelectrical impedance method
(1) The voltage occurring at the flank to the flow of current between the umbilicus and the back correlates significantly with VFA
(2) The voltage occurring is unaffected by subcutaneous fat, because it is located in abdominal cavity.
(3) The voltage becomes higher as visceral fat accumulates even in subjects with the same WC because the electrical resistance of intra-abdominal fat is greater than that of fat-free mass, and the density of the equipotential lines between the two ventral electrodes becomes greater.
