Accuracy can also vary depending on various factors including. Clinical sports nutrition 2 nd ed the mcgraw hill co australia faria fr et al 2013. Bioelectric impedance vector analysis biva is a graphic display that was developed by professor a.

In part 1 of this series you learned about how body fat testing is a prediction not a measurement. Bioelectrical impedance analysis bia is able to make an estimation of body composition eg. Percentage of body fat is strongly associated with the risk of several chronic diseases but its accurate measurement is difficult. This is possible simply because different bodily tissues eg. Piccoli for a better interpretation of body impedance. Measurement errors can range from 35.

Now lets talk about bia. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity. Electrical impedance myography is a third method that measures your bodys. Burke l deakin v 2002. It presents coordinate systems with tolerance ellipses for the graphic display of body impedance and fat mass indices. They compared several body fat tests including bioelectrical impedance the technology used in body fat scales with something called the 4 compartment model.

Body fat scales can be an easy way to track your body fat percentage but they may not tell the complete story about your health. The 4 compartment model is currently the gold standard when it comes to predicting body composition and is the benchmark against which other body fat tests are compared. In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod. Most body water is stored in muscle. However the convienience of this method comes at a price of accuracy. 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 flows through the body and the voltage is measured in order to calculate impedance resistance of the body.

Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Focusing on body fat percentage instead of weight is much more useful.
