Please note that a body weight trend can only be established once a minimum of five measurements have
been taken.

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 Woman
Age poor good very good
10 -100 <50 % 50 - 65 % >65 %
Age poor good very good
10-100 <45 % 45 - 60 % >60 %
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
Age low normal high
10 -14 <44% 44 - 57 % >57 %
15 -19 <43% 43 - 56 % >56 %
20 - 29 <42% 42 - 54 % >54 %
30 - 39 <41% 41- 52 % >52 %
40 - 49 <40% 40 - 50 % >50 %
50 - 59 <39% 39 - 48 % >48 %
60 - 69 <38% 38 - 47 % >47 %
70 -100 <37% 37- 46 % >46 %
Age low normal high
10-14 <36% 36 - 43 % >43 %
15-19 <35% 35 - 41 % >41 %
20-29 <34% 34 - 39 % >39 %
30-39 <33% 33 - 38 % >38 %
