Body water
According to the World Health Organization (WHO 2001), the percentage of body water should normally
lie within the following ranges:
Man
Age poor
10 -100 <50 %
Body fat contains relatively little water. Therefore people with a high body fat percentage have body water
percentages below the recommended values. With endurance athletes, however, 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. Basically, a high body water percent-
age should be the aim.
Muscle percentage
As the percentage of muscle differs from individual to individual, there are no generally valid guidelines.
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%
9. Results in relation to time
Note:
Remember that only long-term trends are important. Short-term fluctuations in weight over a few days are
usually the result of fluid change, due to fluid intake or loss.
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. Sudden changes
within days must be distinguished from medium term changes (over weeks) and long term changes (months).
A basic rule is that short term changes in weight almost exclusively represent changes in water content,
whereas medium and long term changes may also involve the fat and muscle percentages.
• If your weight reduces over the short term, but your body fat percentage increases or remains the same,
you have merely lost water – e.g. after a training session, sauna session or a diet restricted only to rapid
weight loss.
• If your weight increases over the medium term and the body fat percentage falls or stays the same, then
you could have built up valuable muscle mass.
• If your weight and body fat percentage fall simultaneously, then your diet is working – you are losing fat
mass.
• Ideally you should support your diet with physical activity, fitness or power training. This way you can
increase your muscle percentage over the medium term.
• Body fat, body water or muscle percentages should not be added (certain elements of muscle tissue also
contain body water).
