Definition of Bioelectrical Impedance Analysis . While "bioelectrical impedance analysis" sounds technical, BIA devices use straightforward technology. They measure the rate at which a painless low-level electrical current travels through your body.
The impedance of cellular tissue can be modeled as a resistor (representing the extracellular path) in parallel with a resistor and capacitor in series (representing the intracellular path – the resistance that of intracellular fluid and the capacitor the cell membrane).
Bioelectrical Impedance Analysis (BIA) can estimate body composition (e.g. fat mass and fat-free mass) via a small electrical current.
Bioelectrical impedance analysis (BIA) is a method for measuring body composition, including muscle mass, body fat, and total body water. Alternating low and high-frequency electrical currents are sent through the water in the body via contact with electrodes to measure impedance.
RJL Systems is the true pioneer in the Bioelectrical Impedance Analysis (BIA) industry -- with an accurate, quantitative, comprehensive body measurement approach that has been the choice of scores of health professionals and researchers since 1979.
The new portable hand-held Quantum VII Biological Impedance Analyzer (BIA) continuously measures true biological resistance and reactance properties and averages each sample creating a highly accurate BIA for the short and long term study of human body composition by health care professionals.
Bioelectrical impedance analysis (BIA) is used to analyze human body composition by applying a small alternating current through the body and measuring the impedance.
Bioelectrical impedance analysis (BIA) is a simple, inexpensive, quick and non-invasive technique for measuring body composition. The clinical benefit of BIA can be further enhanced by combining it with bioelectrical impedance vector analysis (BIVA).
How should bioelectrical impedance be performed, and how can bioelectrical impedance measurements be standardized? Standardization of procedures is essential. Proper electrode placement is crucial for accurate and reproducible bioelectrical impedance measurements.
Bioelectrical impedance analysis (BIA) is a technique widely used for estimating body composition and health-related parameters.
