InBody uses multiple frequencies in its measurements
By using several different frequencies, more resistance values are attained, providing more information for the InBody scan. The InBody 770 utilised 6 different frequencies that measure each segment, providing a total of 30 separate impedance values.
Electrical current has a different penetration force depending on frequency. Low frequencies measure the water outside the cell (extracelluar water), as they are unable to penetrate the cell wall. Higher frequency will measure the water content inside of the cell (intracellular water) 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. 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.
InBody uses a patented 8-point system of thumb point & palm technology
When measuring impedance through any type of electrode, contact resistance occurs. 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. This 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 are renowned for, if a person was to get on and off, the scan results will be 99% the same.
Measuring your body parts individually
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, legs and 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.
