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 water percentages below the recommended values. With endurance athletes, however, the re-
commended 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 exam-
ple concerning 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 ag-
eing 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. osteoporo-
sis) using this scale.
Little influence can be exerted on bone mass, but it will vary slightly within the influencing factors
(weight, height, age, gender).
Results in relation to time
Note that it is only the long-term trend which counts. Short period fluctuations in weight over a few
days are mostly the result of a loss of fluid.
The interpretation of the results will depend on changes in your overall weight and body fat, body
water and muscle percentages, as well as on the period during which these changes take place. Ra-
pid changes within days must be distinguished from medium term changes (over weeks) and long
term changes (months).
