Bioelectrical
Impedance Analysis
Bioelectrical Impedance
Analysis or BIA is considered one of the most exact and accessible
methods of screening body fat. In conventional BIA, a person is
weighed, then, height, age and gender are entered in a computer. While
the person is lying down, electrodes are attached to various parts of
the body and a small electric signal is discharged that measures the
impedance or resistance to muscle and fat. The more muscle, the lower
the value as the electricity passes easily through lean mass. A
formula in the computer converts all of the data to indicate what
percentage of the body is fat.
Tanita's Patented
BIA Method
Tanita has patented a
revolutionary new way of measuring BIA that is faster, easier, less
intrusive and includes a precision scale as part of the one-step
process. Height, age and gender are entered into a computer and the
person steps on the scale. Electrodes in the foot sensor pads send a
low, safe current through the body. Weight and body fat content are
calculated simultaneously in less than a minute.
