When you step on the scale an electrical current passes through one leg up to the pelvis and down the other. Since the advent of the first commercially available devices.
Measurement Of Body Fat Using Leg To Leg Bioimpedance
Body fat measurement bia. A 2012 study in the international journal of obesity found that 29 of people who were normal weight actually had a body fat percentage in the obese range. 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. Low weight normal overweight and obese. Bia measurements of body fat were categorized across four nominal descriptions. However the accuracy of bia is dependent on several factors and as a result it is likely the least valid measure of body composition discussed in this article. Most body water is stored in muscle.
Bia involves running a light electrical current through your body. To quantify the association between body fat over time with both baseline self perceptions of weight and. The um 028 measures your weight and calculates your body fat using bioelectric impedance analysis bia the same highly accurate fda cleared method used in all our body fat and body composition products. As mentioned before measures like the bmi and wc and formulas based on these measurements cannot. The low cost speed of measurement and lack of need for technical expertise makes bia an attractive option for body composition measurement particularly in epidemiological research. Quantities of fat mass and fat free mass by running a small electrical current through the body.
Measuring the circumference of certain body parts is a simple method of body fat estimation. However the convienience of this method comes at a price of accuracy. Kappa statistics were estimated to compare bia measurements with baseline self perceptions of weight. So it may miss people who look thin. Bioelectrical impedance analysis bia is able to make an estimation of body composition eg. Fat free mass contains mostly water while fat contains very little water.
Body fat scales use technology called bioelectrical impedance analysis bia. In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body. Bia is simple easy to use and can in theory differentiate between fat mass and fat free mass. Bia is one of the quickest and easiest methods for predicting body fat. For example the us army uses a body fat calculation that simply requires an individuals age height. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass.
