Body Fat Measurement Bioelectrical Impedance

Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels. 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 6 Best Body Fat Monitors To Buy In 2020

Body fat measurement bioelectrical impedance. Quantities of fat mass and fat free mass by running a small electrical current through the body. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through the body. In part 1 of this series you learned about how body fat testing is a prediction not a measurement. 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. Bia sends a weak electrical impulse through the. Now lets talk about bia.

This is possible simply because different bodily tissues eg. Body fat scales use bioelectrical impedance analysis bia to estimate the relative percentages of different tissues and substances within the body. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity. 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. 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.

However the convienience of this method comes at a price of accuracy. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Most body water is stored in muscle.
