Bia involves running a light electrical current through your body. Muscle fat bone etc due to their variation in water content the small electrical current passes through the tissues at different speeds.

Body fat measurement bioelectrical impedance. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Bioelectrical impedance analysis bia is a relatively simple quick and non invasive technique to measure 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. 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. This method is commonly used in bathroom scales and handheld devices that measure percent body fat. The faster the current travels from one lead to another the more muscle and less fat the person has.
It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through the body. Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels. Bioelectrical impedance analysis bia definition. Bioelectrical impedance analysis bia determines body composition by running small electrical currents through the body. Because water is a good conductor of electricity the current travels easily through parts of your body composed mostly of water muscle and less easily through fat.
According to the acsm bioelectric impedance analysis bia works by passing a low intensity electric current through the body and measuring its resistance. Since the advent of the first commercially available devices. As the electrical conductivity is different between various bodily tissues eg. However the convienience of this method comes at a price of accuracy. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass. Most body water is stored in muscle.
