Body water percentage
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, how-
ever, the recommended values could be exceeded due to low fat percentages and high muscle
percentage.
This scale is unsuitable for measuring body water in order to draw medical conclusions
concerning age-related water retention, for example. If necessary ask your physician. Ba-
sically, 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 de-
generation somewhat with healthy nutrition (particularly calcium and vitamin D) and regular exer-
cise. 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). Little influence can be ex-
erted on bone mass, but it will vary slightly within the influencing factors (weight, height, age,
gender). No recognised guidelines or recommendations relating to bone mass measurement.
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.
