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, gender and weight or other physical
characteristics such as body type, physical activity level, ethnicity,
etc. 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
circulated. Simply explained, BIA measures the impedance or resistance to
the signal as it travels through the water that is found in muscle and
fat. The more muscle a person has, the more water their body can hold. The
greater the amount of water in a person's body, the easier it is for the
current to pass through it. The more fat, the more resistance to the
current. BIA is safe and it does not hurt. In fact, the signal used
in body fat monitors can not be felt at all either by an adult or child. |

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 making this
a simple one-step process. Tanita's monitor looks just like a bathroom
scale. A person inputs age group, gender and height, then steps onto the
platform. Electrodes in the foot sensor pads send a low, safe signal
through the body. Weight is calculated automatically along with body fat
content in less than a minute. |
