The Pitfalls Of Bodyfat Measurement Part 4 Bioelectrical
Body fat measurement electrical impedance. Bia sends a weak electrical impulse through the. They run a light electrical current through your body measure the degree of resistance or impedance to the flow of the current then use this information to estimate your body fat percentage. Now lets talk about bia. Body fat scales use bioelectrical impedance analysis bia to estimate the relative percentages of different tissues and substances within the body. Bioelectrical impedance bia bia is one of the quickest and easiest methods for predicting body fat. Burke l deakin v 2002.
Here are the 10 best ways to measure your body fat percentage. In part 1 of this series you learned about how body fat testing is a prediction not a measurement. Focusing on body fat percentage instead of weight is much more useful to track fat loss progress. 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. 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. In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod.
Accuracy can also vary depending on various factors including. However the convienience of this method comes at a price of accuracy. Most body water is stored in muscle. Most research shows that body fat scales arent accurate enough to track changes in body composition over time.
