Most body water is stored in muscle. 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.
Self Perceptions Of Weight Vs Body Fat As Measured By
Body fat measurement bioelectrical impedance. This is possible simply because different bodily tissues eg. Bia sends a weak electrical impulse through the. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through 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.
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. A number of methods are available for determining body fat percentage such as measurement with calipers or through the use of bioelectrical impedance analysis. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity. Now lets talk about bia. In part 1 of this series you learned about how body fat testing is a prediction not a measurement. Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels.
In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod. Bioelectrical impedance analysis bia is able to make an estimation of body composition eg. Body fat scales use bioelectrical impedance analysis bia to estimate the relative percentages of different tissues and substances within the body.
