Body Fat Measurement Bioelectrical Impedance

In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod.

Body fat measurement bioelectrical impedance. 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. However the convienience of this method comes at a price of accuracy. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity.

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. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Quantities of fat mass and fat free mass by running a small electrical current through the body.

Now lets talk about bia. This is possible simply because different bodily tissues eg. Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels. Most body water is stored in muscle.

A number of methods are available for determining body fat percentage such as measurement with calipers or through the use of bioelectrical impedance analysis.
