Calculate body fat in accordance with resistance value.
KaradaScan measures body resistance by using weak currency flowing through both hands
and both feet (BI method*).
* BI method (Bioelectrical Impedance/ biological resistance method).
Tissues with more water content in human body tend to conduct electricity (such as muscle
and vein) easily. Fat tissue almost conducts no electricity. The body feature is used to calculate
rate of fat tissue and non-fat tissue.
Currency flowing through human body is very weak (50 kHz, 500
μ
A), which is not stimulant
and is very safe to human body.
In order to obtain body fat and other data from resistance between both hands and both feet,
The five items, i.e., (1) resistance value, (2) height, (3) weight, (4) age and (5) gender are
required, which are obtained in accordance with basic human data collected by the company
independently.
Is the method of whole body measuring, which is not
subject to daily variation.
1 Water content in our body tends to accumulate in our leg during day. That's why we usually
feel dropsy at the feet at dusk or in the evening.
In the morning and dusk, body resistance distribution will change, as water proportion in upper
body and lower body changes.
KaradaScan measures whole body resistance by using electrode of both hands and both feet.
Therefore, it is less subject to variation of water content distribution in human body.
Basic data used to establish body composition formula,
Collect by using measuring method and measuring device
most suitable for various body compositions.
Body fat: weighing method in water (Submerge your head into water pool and exhaust
all air in your lung before measuring body weight. The method to calculate body fat in
accordance with body density is based on Archimedes principle. )
Resting metabolism:breath analyzing device (used to analyze air composition in breath). It
can be used to measure oxygen consumption of breath at quiet time to calculate resting
metabolism.)
V-Fat: X-ray CT (Computed Tomography) device (a medical device photographing images
of transverse section with X-ray without body injury) The area of visceral fat can be
calculated according to the transverse section of the position of the navel in abdomen.
Subcutaneous fat and skeletal muscle: DXA (Dual Energy X-Ray Absorptiometry) method
(measuring body composition at different parts by quantifying bone quantity and body
composition of 2 kinds of X rays with different wave length without the need of resolving
body to calculate weight.)
MRI (Magnetic Resonance Imaging System) (large number of hydrogen atomic nucleus
contained in human body resonate with magnetic field and electric wave. Image hydrogen
atomic nucleus and nuclear magnetic resonance to calculate human body composition.)
