A lower value is often found in athletes. Depending on the type of sports, training intensity and physical con-

stitution, 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 Woman

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 

    Woman

Bone mass

Like the rest of our body, our bones are subject to the natural development, degeneration and ageing pro-

cesses. 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). 

 IMPORTANT:

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 conclu-

sions 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). 

AMR

The active metabolic rate (AMR) is the amount of energy required daily by the body in its active state.

The energy consumption of a human being rises with increasing physical activity and is measured on the 

diagnostic scale in relation to the degree of activity entered (1– 5). 

To maintain your existing weight, the amount of energy used must be reintroduced into the body in the 

form of food and drink. If less energy is introduced than is used over a longer period of time, your body 

will obtain the difference largely from the amount of fat stored and your weight will reduce. If, on the other 

hand, over a longer period of time more energy is introduced than the total active metabolic rate (AMR)
