Body Composition Analyzer

The InBody range of body composition analysers are the only Bio electrical impedance machine with 98% correlation to the DEXA scan across a broad range of population including children, elderly, Athletes and obese people to name a few. It provides a detailed report outlining an individual’s measurements in such things as but not limited to:

– Total Skeletal Muscle Mass

– Total Body Fat

– Total Body Fat Percentage

– Visceral Fat

– Total Body Water

– Segmental Muscle and Fat Analysis

– Bone Mineral Content

– Basal Metabolic Rate


It measures your body parts individually instead as a whole

The technical term for this is Direct Segmental Multi-frequency Bioelectrical Impedance Analysis (DSM-BIA). It separately measures the impedance (resistance to alternating electric currents) of the trunk, arms, and legs of our body.

This new measurement concept measures the resistance of the cross point of two flows and takes the resistance values of the arms, legs and the body trunk.

This technology is patented worldwide and makes a huge difference to the accuracy of your scan results.

Other equipment of lesser technology, measure the whole body as a single cylinder that measures one impedance value for your arms, legs, and trunk.


Accurate measurement of trunk impedance = accuracy

The human body is composed of five cylinders: the arms, the legs and the trunk. With the technology of the InBody, the trunk is directly measured. The trunk is occupied by various internal organs and its metabolic characteristics are different from the other parts of the body. It is important to precisely and directly measure the trunk, although difficult, since the trunk has very low resistance compared to the arms and legs.


Multi-frequency measurement = accurate testing”MuliFrequency

Controlling the path of high frequency waves is very difficult. This technical know-how is an InBody specific specialty and has been accumulated over many years of experience in the field.

Electric current has a different penetration force depending on frequency. Low frequencies travel down the flow of the external surface water and are unable to penetrate the cell wall, thus measuring the water content outside of the cell. A higher frequency will measure the water content inside of the cell because it penetrates the cell wall. By using a diverse set of frequencies, the InBody can accurately measure water contents inside and outside the cell separately.

Also, with the usage of several different frequencies, you are able to provide more information on the body composition because more resistance values are attained. The InBody720 is based on six different frequencies that measure each segment, providing a total of 30 separate impedance values, thus providing accurate body composition information.


8-point tactile point system = reproducibility


When measuring impedance through any type of electrode, contact resistance occurs, and it is important to control the contact resistance in order to correctly measure the resistance in the body.

The InBody uses a unique method of electrode placement. The 8-point tactile method separates the current and voltage starting point, thus measurement always begins at a fixed point in the wrists and ankles. This provides high reproducibility and correct body impedance measurement because the contact resistance from the skin has been removed.


Exclusion of empirical estimations = true body shape and proportionImpedance-Values

Empirical estimations are values that are achieved through observation. This data is useful while measuring the typical body type. But what happens if you are not a typical body type? This is the case for the majority of people.

Due to the separate measurements of the trunk, arms and legs, your InBody results will be correct regardless of age, sex, race, and body type.

What makes InBody Body Composition Analysers the most accurate?

1. The Science
InBody Australia technology is backed by over 50 patents and certifications worldwide, with evidence from hundreds of extensive scientific studies. It is the only machine with 98% correlation to the DEXA scan across a variety of populations and body types including children, elderly, obese and athletes. No other machine was able to be compared due to their usage of empirical data in the overall result. When characteristics of a certain group is to be studied they are not valid for research data due to the intentional values within it. (age, gender, body type, ethnicity, elderly, athlete’s pregnant woman etc.) Empirical estimation exclusion technology that can calculate the body composition for sole impedance, rather than base results of off previous captured data, is exclusive to InBody technology.

2. Empirical data
InBody does not use empirical data – therefore providing the most accurate individual results for you! Empirical estimation is the process of including averages in calculations. Such measurements that can be used in body composition analysis are age, gender, ethnicity and sometimes body type. Estimating these factors decreases result sensitivity, therefore bringing difficulty in monitoring accurate body composition change. On any other machine, change your gender, age or body type and see your results change dramatically – yet you have not changed at all. This empirical estimation exclusion technology is exclusive to InBody.

3. Direct Segmental Multi-frequency Bioelectrical Impedance Analysis (DSM-BIA) acknowledged by patents worldwide
InBody has a patented 8 point tactile electrode system which incorporates specific thumb point and palm technology. InBody separates the thumb and palm placement, unlike other machines that rely on two palm placements only.
Having two points on the palm can change the starting point of voltage and current based on common variables such as hand placement and the size of a hand. This can dramatically change the scan results and reproducibility of each scan.
The patented thumb point and palm technology exclusive to InBody creates highly reproducible data by fixing the starting location of current and voltage, regardless of hand placement.

4. 98.4% as accurate as DEXA
InBody is correlated to be 98.4% as accurate as the DEXA (Duel-Energy X-Ray Absorptiometry) scan across a broad spectrum, non-standardised population including children, elderly, obese and athletes. This is of paramount importance as standardising data produces inaccurate results. The insignificant use of empirical data is seen by its emittance in medical research. InBody has been used extensively throughout medical and scientific research worldwide.

5. Trunk Measurement
InBody is the only machine that directly segmentally measure the trunk. As the trunk occupies the largest volume on the body it is of vital importance to scan correctly for accurate results. All other machines simply estimate it. This is evident by the impedance values shown on each scan. Lack of technology requires other devices to estimate the trunk which is a significant point as it reduces accuracy significantly.
