①
Intracellular Water (
ℓ
) : The water inside each cell
②
Extracellular Water (
ℓ
) : The water outside each cell
③
Protein Mass (kg)
④
Mineral Mass (kg)
Mineral Mass cannot be obtained with BIA methodology, but InBody 720 offers the estimated value of Mineral Mass
because Bone Mineral Mass is closely correlated with FFM. The correctness of this estimated value has been validated by
comparison with the DEXA method. Thus, Mineral mass could be used for screening the subjects who have risk factors of
osteoporosis.
⑤ Body Fat Mass (kg)
⑥
Total Body Water (
ℓ
)
The sum of the intracellular and the extracellular water.
* It is shown as “
ℓ”
on the results sheet. However, mass measured in kilograms (kg) is the basic unit of measure for body
composition components. Therefore, the unit volume of water should be converted to a mass unit. It is a common known fact that the volume of 1 liter(
ℓ
) is
equal to the mass of 1kg in water. This fact allows volume and mass to be interchangeable i.e. used at the same time.
⑦
Soft Lean Mass (kg)
The ideal weight is calculated based on subject’s height. A subject’s soft lean mass can be estimated using average
weight and average percent body fat. Problems occur only when the soft lean mass is less than the average, however,
no difficulties are encountered when soft lean mass is greater than average.
⑧
Fat Free Mass (kg)
The sum of soft lean mass and the mineral mass.
⑨
Weight (kg)
Ideal weight is based on subject s height. The basic unit of measure for water is volume.
