However the convienience of this method comes at a price of accuracy. Body fat percentage scales use a method known as bioelectrical impedance bia to estimate your body composition.

Body fat measurement electrical impedance. Fat free mass contains mostly water while fat contains very little water. Electrical impedance myography is a third method that measures your bodys response to small electrical currents. Bio electrical impedance analysis bia is a method of assessing your body composition the measurement of body fat in relation to lean body mass. According to the acsm bioelectric impedance analysis bia works by passing a low intensity electric current through the body and measuring its resistance. How accurate are body fat scales. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass.
Today we reaffirm our commitment to live by our stated values for equality diversity and openness. A message to the doylestown health family and the community jim brexler president and ceo. Such scales work with the help of sensors underneath your feet that use bioelectrical impedance. When you step on the scale a small electrical current runs up through your leg and across your. 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. In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body.
The faster the current travels from one lead to another the more muscle and less fat the person has. 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. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Bia sends a weak electrical impulse through the. Most body water is stored in muscle. Here are the 10 best ways to measure your body fat percentage.
Body fat tied to heart risks in normal weight adults from a scientific point of view most devices used for bia will measure the difference in impedance the amount of opposition an. Since the advent of the first commercially available devices. Bia involves running a light electrical current through your body. Body fat scales use bioelectrical impedance analysis bia to estimate the relative percentages of different tissues and substances within the body.
