Most body water is stored in muscle. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat.
Solved Part D Bioelectrical Impedance Analysis Is A Comme
Body fat measurement bioelectrical impedance. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through the body. A number of methods are available for determining body fat percentage such as measurement with calipers or through the use of bioelectrical impedance analysis. The body fat percentage is a measure of fitness level since it is the only body measurement which directly calculates a persons relative body composition without regard to height or weight. Bia sends a weak electrical impulse through the. In part 1 of this series you learned about how body fat testing is a prediction not a measurement. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity.
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 is able to make an estimation of body composition eg. Bioelectrical impedance analysis bia is a commonly used method for estimating body composition in particular body fat and muscle massin bia a weak electric current flow through the body and the voltage is measured in order to calculate impedance resistance of the body. Now lets talk about bia. This is possible simply because different bodily tissues eg. In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod.
Body fat scales use bioelectrical impedance analysis bia to estimate the relative percentages of different tissues and substances within the body. Quantities of fat mass and fat free mass by running a small electrical current through the body. However the convienience of this method comes at a price of accuracy.
