Microlife WS80
Electronic scale and body analyzer Microlife WS80 (Diagnostic scale - Body Fat monitor)
This diagnostic scale will allow the assessment of body composition. Consequently, you can combine a proper diet with some form of physical activity, both of which are essential for increasing quality of life, health and disease prevention.

It measures:
the weight
fatty meal
water content
muscle mass (in kg)
bone mass
body mass index (kg/m 2 )
basal metabolic rate (kcal)


Important notions about the composition of the human body.
Knowing an individual's body composition is very important for assessing their health. It is not enough to know the weight, but also its quality, and from this point of view body mass is divided into two major categories:
non-fat mass: bones, muscles, internal organs, water, blood
fat mass: fat cells.

The percentage of fat mass.
Body fat percentage is the sum of essential (or primary) and stored (or excess) fat. Primary fat is necessary in metabolic processes, and part of the stored fat, which is theoretically a surplus, is necessary for those who perform physical activities.
For a man, a percentage of fat mass between 17-26% is considered normal, and for women, between 22-31%. This percentage increases with age.

The percentage of water
The percentage of water in the body is an important indicator of a person's well-being. Studies show that 57% is optimal, but a plus or minus 10% margin is not a problem. The percentage of water is higher in childhood, but decreases with age. Women, usually having a greater amount of adipose tissue, fall at 55-58%, and men at 60-62%. Normally, below 40% is considered too low, above 70%, too high. Weight variations that occur within a few hours are completely normal and are due to water retention, and the extracellular fluid is solely responsible for these rapid variations.

Muscle mass
Muscle mass is an important component in determining a healthy body composition.
People with a higher percentage of muscle mass move more easily, but consume a greater amount of energy. Physical activity is very important in maintaining health, and the percentage of muscle mass is a useful indicator in its control.
The normal percentage of muscle mass is 38-54% of body weight in men and 28-39% in women, depending on age and physical condition.

Bone mass
Bone mass grows very quickly in childhood and reaches its maximum between 30-40 years of age. Then, it decreases slightly with age.
Healthy eating and regular physical activity, including muscle-building exercises, can slow bone degeneration. However, significantly influencing bone mass is quite difficult.
Factors such as age, sex, weight and height have little influence on bone mass. Its average for adults is 15% for men and 12% for women. No validated classifications or recommendations for bone mass are known.

Body Mass Index (BMI)
BMI is a statistical measure of weight for height that is commonly used to classify adults into: underweight, overweight, obese. It is calculated by dividing a person's weight by the square of that person's height.

The classification according to WHO is as follows:
Normal: 18.50-24.99 kg/m2
Underweight: under 18.50 kg/m2
Overweight: over 24.99 kg/m2
Obese: over 29.99 kg/m2

Basal Metabolic Rate (BMR)
BMR, expressed in kcal, represents the energy intake that the body needs, in a state of total rest, to maintain its vital functions. About 70% of the total energy of the human body is consumed for the vital functions, ensured by the internal organs. Around 20% is consumed for physical activities, and 10% for food digestion. An estimate can be made using an equation, where the variables are age, sex, height and weight. There are no known classifications or validated recommendations about BMR.

Suggestions for use
Place the scale on a flat and rigid surface.
Soft or uneven floors (eg carpet, carpet, linoleum) can cause fluctuating measurements of your weight.
Step onto the scale with your feet parallel and your weight evenly distributed.
Sit still until the scale finishes measuring.
It is important to weigh yourself with bare feet, dry and correctly positioned on the electrodes. For proper operation of the scale, avoid feet touching each other.
This device can be used as a simple scale by any person.

The following categories of people should not also have body composition analysis:
pregnant women
people under cardiovascular treatment
people with pacemakers or other medical, electronic devices
people with fever
children under 10 years old
people on dialysis, with leg edema, with dimorphism or osteoporosis

Weigh yourself on the same scale every time, at the same time of day, preferably undressed and before breakfast. To get accurate results, weigh yourself twice, and if the two values ​​are different, then your weight is between the two values. From the moment you wake up, wait about 15 minutes before weighing to allow the water in your body to distribute evenly.
The surface of the scale can be slippery if it is wet.
If an error occurs during body composition analysis, the device will shut down automatically.

The accuracy of the measurement can be altered in the following cases:

• a large amount of alcohol / medication / drugs / coffee in the body
• after an intense physical effort
• during illness or pregnancy
• after a larger meal or if you are dehydrated
• you have not set your personal data correctly (weight, age, gender)
• your feet are wet or dirty

ATTENTION :
Body composition measured with this device is indicative. For more information, consult your doctor or dietician.
The analyzer function of this scale can only be used by people between 10-100 years old and between 100-200 cm tall.

To obtain accurate measurements, place the scale on a flat, rigid surface. Start the scale by applying a short kick to the center of the platform to activate the vibration transducer.
