Bioelectrical impedance analysis bia is a safe and cost efficient method that avoids exposure to radiation and is used to measure body composition. Bioelectrical impedance analysis or bioimpedance analysis bia is a method of assessing your body composition the measurement of body fat in relation to lean body mass.
The Skinny On Hidden Body Fat Singapore News Amp Top Stories
Bioelectrical impedance analysis for body fat measurement. That is not accounted for in this body fat analysis. It is based on the difference in resistance when an electrical current is conducted through fat or lean components of the body. Most body water is stored in muscle. It works fast and that compels a compromise on accuracy. It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. Quantities of fat mass and fat free mass by running a small electrical current through the body.
Bioelectrical impedance analysis bia is a relatively simple quick and non invasive technique to measure body composition. Of the three bioelectrical impedance analysis devices they tested the omron hbf 306 single frequency hand to hand electrodes had the largest error rate for estimating body fat percentage clocking in at 79. Bioelectrical impedance analysis bia is a method for measuring body composition based on the rate at which an electrical current travels through the body. Body fat adipose tissue causes greater resistance impedance than fat free mass and slows the rate at which the current travels. Bioelectrical impedance analysis bia is able to make an estimation of body composition eg. Bia or bioelectrical impedance analysis is a non invasive measurement of body fat lean muscle mass and hydration.
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. That is if the omron puts you at 15 body fat it could really be anywhere between 229 and 71. Bioelectrical impedance cons bioelectrical impedance is not very accurate. 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. The second disadvantage is that a person may have little body fat in arms chest and thighs and may have excess fat elsewhere in the body. Biva bioelectrical impedance vector analysis biva as an integrated part of bia measurement is a simple quick and clinically valuable method for assessing fluid status tbw and body cell mass bcm.
This method plots the direct impedance measurements resistance r and reactance xc as a bi variate vector in a nomogram figure figure11.
