Values will often be lower for fitness enthusiasts. Depending on the sporting activities performed, the train-

ing intensity and the physical constitution, the results may still be below the stated standard values. Please 

note, however, that there may be a risk to health in the case of extremely low values. 

Body water content

The body water content in % is normally within the following ranges:

Male

Female

Age

Poor

Good

Body fat contains relatively little water, therefore body water content may be below the standard values in 

persons with a high body fat percentage. On the other hand, endurance athletes may exceed the standard 

values due to having low levels of fat and a high muscle percentage.

The body water calculation performed using this scale is not suitable for drawing medical conclusions, 

for example in the case of age-related water retention. Consult your doctor where necessary. A high body 

water content is generally desirable.

Muscle percentage

Bone mass

Like the rest of our body, our bones are subject to natural growth, shrinking and ageing processes. Bone 

mass increases rapidly during childhood and reaches its peak between the ages of 30 and 40. As we
