Impedance is frequency sensitive; at low frequency the electric current flows preferentially through extracellular water ECW only while at high frequency the current can cross cell membranes and hence flows through total body water TBW.
In bioimpedance spectroscopy devices BIS resistance at zero and infinite frequency can be estimated and, at least theoretically, should provide the optimal predictors of ECW and TBW and hence body fat-free mass respectively.
In practice, the improvement in accuracy is marginal. The use of multiple frequencies or BIS in specific BIA devices has been shown to have high correlation with DXA when measuring body fat percentage. The electrical properties of tissues have been described since These properties were further described for a wider range of frequencies on a larger range of tissues, including those that were damaged or undergoing change after death.
InThomasset conducted the original studies using electrical impedance measurements as an index of total body water TBWusing two subcutaneously inserted needles. InHoffer concluded that a whole-body impedance measurement could predict total body water.
The equation the squared value of height divided by impedance measurements of the right half of the body showed a correlation coefficient of 0. This equation, Hoffer proved, is known as the impedance index used in BIA. InNyober validated the use of whole body electrical impedance to assess body composition.
By the s the foundations of BIA were established, including those that underpinned the relationships between the impedance and the body water content of the body.
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. InLukaski published empirical equations using the impedance index, body weight, and reactance.
InKushner 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. Inan eight-polar stand-on BIA device, InBodythat 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.
InAURA 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. Read Edit View history. Tools Tools.

Introduction Loss of body weight and depletion of fat free muscle mass are common and serious problems in patients with chronic obstructive pulmonary disease COPD irrespective of the degree of airflow limitation [ 1 — 3 ]. Basic principles Bioelectrical impedance analysis BIA BIA is a method for estimating body composition. From the determined impedance a number of BIA parameters can be estimated [ 20 ]: Body cell mass BCM consists of all cells that have an effect on metabolism e. extracellular water retention e. extracellular loss of water e. high portion of muscle, water retention e. Factors impacting BIA results [ 16 , 18 , 20 , 23 , 25 ]: 1. weight and height should be measured directly by the investigator 2. position of the body and limbs supine position, arms abducted at least 30°, legs abducted at approximately 45° 3. consumption of food and beverages no beverages for at least 12 hours previously, fasted state for at least 2 hours 4. medical conditions and medication that have an impact on the fluid and electrolyte balance; infection and cutaneous disease that may alter the electrical transmission between electrode and skin 6. environmental conditions e. ambient temperature 7. individual characteristics e. skin temperature, sex, age, race 8. ethnic variation 9. non-adherence of electrodes, use of wrong electrodes, loosening of cable clip, interchanging of electrodes BIA parameters are largely dependent on the patient's hydration status. 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.

Ignoring variables like fluid balance and cell membrane health could leave you vulnerable to serious health issues. To many, a high BMI automatically equates to being overweight.
You may have even been told you need to lose weight to reduce your risk of developing chronic illnesses. The truth is, such a simple number cannot capture something as complex as your health. Your BMI is based on just two numbers: your weight and your height.
This puts you at the same risk of developing chronic disease as someone who is obviously overweight — and you might not even know it. You need more than BMI alone. BIA is the gold standard in body fat measurement. The process of BIA is quick and simple.
Depending on the machine we use, you will lie down or stand up. There are four electrodes connected to your body — one in each hand and one touching each foot.
The electrodes measure the flow of the current as it runs through your body. In a matter of minutes, we obtain an estimate of the amount of water in your body, which is used to determine your total fat-free mass.
The BIA device then takes into account other variables, such as your height, gender, and weight to calculate your total body fat percentage. A BIA measures several key objective markers of health also known as biomarkers , including:.
When the values of these biomarkers fall within specific target ranges, they can indicate a high level of wellness and low risk for many chronic diseases. When they fall outside their optimal ranges, we can use that information to modify your diet, exercise, and lifestyle habits.
It can also indicate your need for targeted strategies, such as systemic detoxing, enhancing nutrient absorption, or increasing mineral reserves. A BIA is the start of your journey to optimal health.
By routinely examining these biomarkers, we can identify areas of your health that need improvement long before any chronic issues develop.
Ready to come in for your BIA appointment? There are just a few guidelines to follow before your test:. As a clinic that specializes in Personalized Systems Medicine, MaxWell Clinic understands the impact body composition has on your health.
BIA is also one of the many extensive diagnostic tests included in our comprehensive MaxWell Care plan. MaxWell Care is a 3- or month program designed to uncover the root cause of your symptoms and help restore true health and vitality to your life.

This principle serves as the foundation for BIA. More Than A Fat Measurement Tool BIA is much more than a superficial tool to measure fat.
How Does Bioelectrical Impedance Analysis Work? What Measurements Does Bioelectrical Impedance Analysis Provide? A BIA measures several key objective markers of health also known as biomarkers , including: Phase angle : An indicator of cellular health independent of weight.
Phase angle values vary depending on your age and gender. Resistance : Resistance is the effect on an electrical current caused by different components in your body. A high resistance value indicates low amounts of fat-free body mass. A low resistance is consistent with high amounts of fat-free body mass.
A high value means healthy cells. This includes bone and muscle tissue. BCM includes the water inside living cells.

The Best multivitamin supplements electrical current impedane passed through the Best multivitamin supplements Antioxidant-Rich Fruits conductive surfaces or electrodes. Conductivity is higher through fat free mass which includes muscle, bone and water than through fat mass which contains very little water. Different body components have varying levels of impedance in response to different frequencies of the electrical current. Output is commonly provided in the form of an impedance value expressed in the unit Ohms, Ω; approximate range between Ω - Ω. Interpretation of the impedance value varies by BIA instrument type. Bioelectricap to know impedajce Bioelectrical impedance analysis are Bioeletrical of? Here's a painless and easy impexance to estimate impedsnce fat. In addition to the bathroom Bioelectrocal, Best multivitamin supplements our clothes fit, and how we feel day to day, body Best multivitamin supplements measurements provide Bioelectrical impedance analysis with a bit more information about where we stand with our health and fitness goals. Simply put, getting your body composition estimated provides information about how much of your body is fat and not fat muscle, bone and organs. You are likely aware that too much body fat is a reason for concern. Carrying too much fat especially around the middle increases the chance of developing conditions such as type 2 diabetes, heart disease, hypertension, and joint disease.
