What is InBody

The InBody body composition analysers provide a detailed report outlining an individual’s measurements in such things as but not limited to:

  • Total skeletal muscle mass
  • Total body fat in kilograms
  • Total body fat percentage
  • Visceral fat
  • Total body water
  • Segmental muscle and fat analysis
  • Bone mineral content
  • Basal metabolic rate


InBody’s patented technology is unique as it scans you for you, it does not use any assumptions in its assessment but provides results which are extremely precise and as unique as the person standing on them. InBody does not use inputted age or gender, unlike other devices. Age and gender are therefore used as averages in a scan and will substantially affect the outcomes. Many devices may even ask for ethnicity and body types as well. We ask for age and gender simply as a means of providing guidelines (these are found generally in a bracket format, next to your actual results) to allow you to compare your results against a broad spectrum average. Simply put, change your age and gender on an InBody device and your results will not change as you have not changed. The non-use of any assumptions is what sets InBody’s technology apart and is one of the underpinning reasons as why InBody is used in extensive studies, used by top sports people, medical intuitions, NASA and utilised in over 70 countries worldwide. This is a brilliant tool to prove the preciseness of any device as changing age and gender, your scan should not change – if it does, it shows they are utilising assumptions not actual individual assessments. InBody is the only device that does not use inputted data, the results speak for themselves.


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 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 InBody 770 is based on 6 different frequencies that measure each segment, providing a total of 30 separate impedance values.


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.

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 is advantageous as the contact resistance from the skin has been removed. This creates the high precision of reproducing the results that InBody is renowned for, that being said if a person was to get on and off the scan results will be 99% the same.


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.

Why is this important?

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. Although difficult, it is important to precisely and directly measure the trunk, since the trunk has very low resistance compared to the arms and legs.
