14_ABOUT BODY COMPOSITION
ABOUT BODY COMPOSITION
Body Composition
Human body consists of body fat and lean body. Lean body means non-fat constituents of human body
like body water, muscles, mineral, etc.
Body water is divided into intra- and extra-cellular water and the ratio between them is controlled and
maintained within a certain range. Body fat is piled beneath the skin and between abdominal organs. Body
fat is hydrolyzed to make energy needed to normal physiological function when energy supply through
food intake is not sufficient, but excessive fat in the body itself is a kind of disease and causes lifestyle
diseases.
Healthy people maintain the balance of body composition in a steady proportion but unhealthy people
persons fail to keep this balance. When the balance in body composition is broken, diseases like obesity,
malnutrition, osteoporosis, etc. can be caused.
Obesity
Various methods can be used to assess obesity but the key factor in obesity assessment is the amount of
fat accumulated in the body.
In general, obesity is defined as the state of not only excessive weight compared with height (visible obese)
but also excessive body fat compared with weight (invisible or visible obese).
Strictly speaking obesity is the state that body fat occupies considerably high ratio to weight.
Necessity of Body Composition Analysis
Body Composition Analysis is a good indicator in finding possible health problems. Body composition
analysis enables professionals to find obesity or imbalance in body composition at an early stage and
helps subjects keep their body healthy.
Waist to hip ratio
Waist to hip ratio (W.H.R.) shows the distribution of fat stored in one’s abdomen and hip. It is simple but
useful to assess body fat distribution. Body fat is stored in two distinct ways. They are often categorized
into and called 'apple' and 'pear' type. Apple type shows bigger girth of waist than hip and pear type has
bigger girth of hip than waist. If body fat in abdomen increases more, the risk to cardiovascular diseases,
diabetes, etc. becomes higher.

User Manual BC720
ABOUT BODY COMPOSITION_15
Abdominal Fatness
Body fat is divided into subcutaneous fat and visceral fat. Visceral obesity is considered to be a critical risk
factor along with Percentage of body fat.
Lipoprotein lipase can be easily activated in visceral fat, and it causes visceral fat to be dissolved easily.
Dissolved visceral fat goes into liver through the blood vessel and causes fatty liver or increases lipid in
the blood. It also elevates the risk of hyperinsulinemia, hypertension, and cardiovascular disease.
Visceral fat generally occupies 10 ~ 20 % of body fat and visceral obesity is assessed based on the
indicators below.
the cross sectional fat area between L4 ~ L5 is 100 cm2and over
the visceral fat to subcutaneous fat ratio is 0.4 and over
the waist to hip ratio (W.H.R.) is over 0.9 (male) / 0.85 (female)
the circumference of waist is over 102 cm/45 inches (male) _ 88 cm / 35 inches (female)
Visceral fat increases after 30s in men and after Menopause in women. It is more common in men than
women and the old than the young. Visceral fat tends to increase with aging. Because the combustion
rate per minute of visceral fat is higher than that of subcutaneous fat, visceral fat can be easily reduced
by exercise or dietary control in case of abdominal obesity. W.H.R. is the ratio of waist to hip circumference
and has relation to one’s figure.
Segmental Analysis
This device analyzes soft lean mass, body fat mass, total body water and E.C.W./T.B.W. of five body parts;
trunk, right arm, left arm, right leg, and left leg. This function can be used as an assessment tool to
evaluate the result of exercise or rehabilitation treatment.
Age Matched of Body
It is the estimated physical age of the subject considering body composition analysis result, gender, and
biological age. This is calculated by comparing the optimal body composition based on the gender and
biological age of the subject with the actual analyzed body composition. It can be used to evaluate the
subject’s health and body development.
Study
It is the provided impedance.
Impedance indicates the segmental impedance of five body parts (left and right arms, left and right legs,
and trunk) corresponding to each frequency (1~ 1000 kHz).

5. Ultrasonic Height Meter SM103
It is an instrument to measure users' Height more
accurately and quickly. It employs standoff determination
method using ultrasonic sensor. It combines the
technology of artificial intelligence and reflected
characteristics of ultrasonic height meter.
<Good point of using SM103 as an option>
1) It automatically measures height.
2) Fast measurement
3) Accurate measurement
4) LCD monitor attached to the column leads the user to
measure height in correct way.
<When using SM103>
1) Install it in a place with stable temperature.
2) Do not install it at the location facing the heater and
air conditioner.
3) Do not put a sticker or foreign things on body of the
SM103.
4) Nothing should be placed within a radius of 60cm
Note
Measuring height in the morning is even average 1~2cm higher than in the evening,
because vertebral cartilage is pressed maximum in the evening by owns weight.
