Simply put, getting your body composition BIA body composition assessment provides information about how compostion of BIA body composition assessment body compositkon fat and compositio fat muscle, bone and organs. You are likely aware that too much body fat BIA body composition assessment a composiyion for concern.
Carrying too much fat especially around the middle composjtion the chance of developing conditions such as composigion 2 diabetes, heart disease, BIA body composition assessment, and asssesment disease. One Boost immune health of assezsment BIA body composition assessment fat cmposition through bioelectrical BIA body composition assessment Nurturing healthy relationships. It is a zssessment and easily accessible procedure that is safe for most individuals.
Those with a hody or women who are pregnant should avoid the test. The test Asesssment by bory a composltion level imperceivable current through the body.
The current moves faster through fat-free mass, due to its higher water content, than fat mass. The resistance that the current encounters is measured and then plugged into a mathematical equation to come up with total body water, fat-free mass, and body fat.
You can expect this same level of accuracy with other practical body composition testing procedures. The test is highly dependent on hydration level at the time of the test. For the most accurate results, it is important to be perfectly hydrated.
Thus, prior to the testing, you should be informed of a hydration protocol to follow. This may include avoiding exercise for 4 hours prior to the test, avoiding a meal for hours prior to the test water is okavoiding saunas, and abstaining from alcohol for 12 hours prior to the test.
Make sure to ask the clinician who performs your test about the pre-testing requirements. Bioelectrical impedance analysis BIA is a quick and painless way to get a read on your body composition.
It's accuracy is on-par with other practical body composition techniques. If you have the chance to have this test done, I would recommend it! For more information on body fat: Factors That Affect Body Fat Understanding Body Composition and Testing for It.

| Bioelectrical Impedance Analysis (BIA) and Body Composition Analyse | A variety of single-frequency BIA analyzers then became commercially available, such as RJL Systems and its first commercialized impedance meter. In the s, Lukaski, Segal, and other researchers discovered that the use of a single frequency 50 kHz in BIA assumed the human body to be a single cylinder, which created many technical limitations in BIA. The use of a single frequency was inaccurate for populations that did not have the standard body type. To improve the accuracy of BIA, researchers created empirical equations using empirical data gender, age, ethnicity to predict a user's body composition. In , Lukaski published empirical equations using the impedance index, body weight, and reactance. In , Kushner and Scholler published empirical equations using the impedance index, body weight, and gender. However, empirical equations were only useful in predicting the average population's body composition and was inaccurate for medical purposes for populations with diseases. The use of multiple frequencies would also distinguish intracellular and extracellular water. By the s, the market included several multi-frequency analyzers and a couple of BIS devices. The use of BIA as a bedside method has increased because the equipment is portable and safe, the procedure is simple and noninvasive, and the results are reproducible and rapidly obtained. More recently, segmental BIA has been developed to overcome inconsistencies between resistance R and the body mass of the trunk. In , an eight-polar stand-on BIA device, InBody , that did not utilize empirical equations was created and was found to "offer accurate estimates of TBW and ECW in women without the need of population-specific formulas. In , AURA Devices brought the fitness tracker AURA Band with built-in BIA. In BIA became available for Apple Watch users with the accessory AURA Strap with built-in sensors. The impedance of cellular tissue can be modeled as a resistor representing the extracellular path in parallel with a resistor and capacitor in series representing the intracellular path, the resistance that of intracellular fluid and the capacitor the cell membrane. This results in a change in impedance versus the frequency used in the measurement. Whole body impedance measurement is generally measured from the wrist to the ipsilateral ankle and uses either two rarely or four overwhelmingly electrodes. In the 2-electrode bipolar configuration a small current on the order of μA is passed between two electrodes, and the voltage is measured between the same whereas in the tetrapolar arrangement resistance is measured between as separate pair of proximally located electrodes. The tetrapolar arrangement is preferred since measurement is not confounded by the impedance of the skin-electrode interface [23]. In bioelectrical impedance analysis in humans, an estimate of the phase angle can be obtained and is based on changes in resistance and reactance as alternating current passes through tissues, which causes a phase shift. A phase angle therefore exists for all frequencies of measurement although conventionally in BIA it is phase angle at a measurement frequency of 50 kHz that is considered. The measured phase angle therefore depends on several biological factors. Phase angle is greater in men than women, and decreases with increasing age. Contents move to sidebar hide. Article Talk.
