①
Segmental Water Analysis(Body Water)
The InBody S10 is available to show the body water of each segmental body part.
Body water is proportionate to soft lean mass.
If soft lean mass has increased due to exercise or other efforts, the body water should have
increased as well.
②
ECW/TBW
InBody S10 measures intracellular water levels and extracellular water levels separately and
makes assessments by finding the balance between the body water levels. The body water
ratio(ECW/TBW) presents not only each part of body such as arms, trunk, and legs, but
also the whole body.
The healthy person shows maintenance in a certain ratio of the intracellular water level and
extracellular water level.
However, if the extracellular water level increases, this can cause an edema. The normal
range for ECW/TBW (edema index) is considered 0.36-0.39. The ratio between 0.39 to 0.40
means ‘slight edema’, and over 0.40 means edema.
Body water ratio (edema index)(ECW/TBW)
= Extracellular water / Total body water
③
Nutrition Index
a. BCM(Body Cell Mass)
The body cell mass is the sum of cells that are made up of the intracellular water level and
proteins and is one of the methods to evaluate the nutritional staus. For a healthy normal
person, we can do a nutrition assessment through a BMI or body fat level. However, a
examinee with health problems might have an abnormal increase in the amount of
extracellular water due to abdominal dropsy or edema. It leads to inaccurate result of body
composition and overestimates fat free mass since the extracellular water has increased.
Therefore, it is appropriate to use the BCM index which does not get influenced by
extracellular water level in its analysis to assess nutritional levels.
b. BMC (Bone Mineral Content, kg)
BMC refers to the mineral content inside your bones. The BMC index can be measured
through the DEXA (Dual Energy X-ray Absorptiometry). The InBody S10 uses regression
analysis to obtain BMC.
c. AC(Arm circumference)
AC refers to the arm circumference of the left arm. AC is used to assess the nutritional state
of your protein levels. The diagnosis of examniee’s nutritive condition is made by constant
monitoring changes in AC, not a one-time measurement.
