Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

An X-ray of your entire body can help a healthcare provider work out your body composition, or how much of your body is made up of fat, muscle and bone. Bioelectrical impedance analysis (BIA).
A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis. The body fat percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or ...
Standard bioelectrical impedance analysis (BIA), like EIM, also employs a weak, high frequency electric current to measure characteristics of the human body. In standard BIA, unlike EIM, electric current is passed between electrodes placed on the hands and feet, and the impedance characteristics of the entire current path are measured.
In the field of human health monitoring is better known as bioelectrical impedance analysis (BIA) [31] and is used to estimate body composition [32] as well as different parameters such as total body water and free fat mass. [33]
Officials in in Wisconsin said DNA evidence has solved a more than 65-year-old cold case involving missing 7-year-old Michigan boy Markku Jutila, born as Chester Breiney. The Ozaukee County ...
Another method of determining total body water percentage (TBW%) is via bioelectrical impedance analysis (BIA). In the traditional BIA method, a person lies on a cot and spot electrodes are placed on the hands and bare feet. Electrolyte gel is applied first, and then a weak current of frequency 50kHz is introduced.
