A lower value is often found in athletes. Depending on the type of sports, training intensity and physical
constitution, values may result which are below the recommended values stated.
It should, however, be noted that there could be a danger to health in the case of extremely low values.
Body water
The body water percentage is normally within the following ranges:
Man
Age poor
10 -100 <50 %
Body fat contains relatively little water. Therefore persons with a high body fat percentage have body wa-
ter percentages below the recommended values. With endurance athletes, however, the recommended
values could be exceeded due to low fat percentages and high muscle percentage.
Body water measurement with this scale is not suitable for drawing medical conclusions, for example con-
cerning age-related water retention. If necessary ask your physician.
Basically, a high body water percentage should be the aim.
Muscle percentage
The muscle percentage is normally within the following ranges:
Man
Age low
10 -14 <44%
15 -19 <43%
20 - 29 <42%
30 - 39 <41%
40 - 49 <40%
50 - 59 <39%
60 - 69 <38%
70 -100 <37%
Bone mass
Like the rest of our body, our bones are subject to the natural development, degeneration and ageing
processes. Bone mass increases rapidly in childhood and reaches its maximum between 30 and 40 years
of age. Bone mass reduces slightly with increasing age. You can reduce this degeneration somewhat
with healthy nutrition (particularly calcium and vitamin D) and regular exercise. With appropriate muscle
building, you can also strengthen your bone structure.
Note that this scale will not show you the calcium content of your bones, but will measure the weight of all
bone constituents (organic substances, inorganic substances and water).
Attention: Please do not confuse bone mass with bone density. Bone density can be determined only by
means of a medical examination (e.g. computer tomography, ultrasound). It is therefore not possible to
draw conclusions concerning changes to the bones and bone hardness (e.g. osteoporosis) using this scale.
Little influence can be exerted on bone mass, but it will vary slightly within the influencing factors (weight,
height, age, gender).
BMR
The basal metabolic rate (BMR) is the amount of energy required by the body at complete rest to maintain
its basic functions (e.g. while lying in bed for 24 hours). This value largely depends on weight, height and
age. It is displayed on the diagnostic scale in kcal/day units using the scientifically recognized Harris-Ben-
edict formula.
Your body requires this amount of energy in any case and it must be reintroduced into your body in the
form of nutrition. If you take on less energy over the longer term, this can be harmful to your health.
