Impedance is a measure of the degree a substance resists the flow of electrical current of a given voltage. Administered solutions however are detected immediately.

Impedance body measurement. Orally ingested water which has not yet been absorbed by the body is not measured. They run a light electrical current through your body measure the degree of resistance or impedance to the flow of the current then use this information to estimate your body fat percentage 2. In simple terms impedance measures the effective resistance to current flow through the body by applying a small alternating current. If your impedance index is more than 1273 you are at a better level of health and fitness than if it is below 1273. Most body water is stored in muscle. How accurate are body fat scales.
Since the advent of the first commercially available devices. Impedance measurement instruments are employed for development characterization and test of sensors electronic components electrochemical cells and materials. Body fat percentage scales use a method known as bioelectrical impedance bia to estimate your body composition. In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body. The symbol zdenotes impedance and is measured in ohms. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass.
Therefore if a person is more muscular there is a high chance that the person will also have more body water which leads to lower impedance. The same goes for ascites because it is not part of the lean body mass. Normal values for both men and women are greater than 1273. Is another measurement of your general health. They are capable of extracting complex impedance vectors at a single test condition or while sweeping source parameters like frequency amplitude and dc bias. Normal values for both men and women are greater than 1273.
Total body water tbw impedance measurements provide a quite accurate picture of electrolyte water contained in tissue.
