Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass. Bia involves running a light electrical current through your body.
Bioelectrical Impedance Analysis Bia Science For Sport
Body fat measurement bioelectrical impedance. Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels. Muscle fat bone etc due to their variation in water content the small electrical current passes through the tissues at different speeds. Accurate measurement of body water is central to the prediction of body fat from bia. 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. Fat free mass contains two types of water intracellular and extracellular water. Intracellular water is that found in the bodys cells.
Most body water is stored in muscle. Bioelectrical impedance analysis bia determines body composition by running small electrical currents through the body. As the electrical conductivity is different between various bodily tissues eg. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through the body. However the convienience of this method comes at a price of accuracy. In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body.
A small current is used to measure the resistance at difference frequencies against the various tissues in the body eg fatlipid has a high resistance to the flow of current therefore shows a high impedance reading. Bia or bioelectrical impedance analysis is a non invasive measurement of body fat lean muscle mass and hydration. Since the advent of the first commercially available devices. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Thus intracellular water is mostly observed in the muscles bones and organs.
