Body measurements Info

Now lets talk about bia. Such scales work with the help of sensors underneath your feet that use bioelectrical impedance. Since the advent of the first commercially available devices. In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body. When you step on the scale a small electrical current runs up through your leg and across your. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass.

Body circumference measurements and body fat scales that use bioelectrical impedance are both methods you can do on your own. In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod. A small current is used to measure the resistance at difference frequencies against the various tissues in the body eg fatlipid has a high resistance to the flow of current therefore shows a high impedance reading. 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. In part 1 of this series you learned about how body fat testing is a prediction not a measurement.

Bia sends a weak electrical impulse through the. Therefore if a person is more muscular there is a high chance that the person will also have more body water which leads to lower impedance. However the convienience of this method comes at a price of accuracy. Bia or bioelectrical impedance analysis is a non invasive measurement of body fat lean muscle mass and hydration. Most body water is stored in muscle. While not as accurate as skinfold measurements taken by a trained.
