instructions in order to avoid danger and damage.
6.1 What is body fat percentage?
The body fat percentage is derived from the ratio between body weight and body fat.
6.2 Measurement of the body fat percentage
To determine the body fat percentage, the BIA-method (bioelectrical
impedance analysis) has been developed.
The resistance of the body is measured while a small and harmless
electric current is sent through the body. The resistance is higher in
adipose tissue while the current flows more easily in fat-free mass. Due to
the measurement of resistance with the body size of the person, its age
and sex, it is possible to estimate the percentage of fat and water of the
body.
The percentage of fat is influenced by the hydration of the body. Some
hours after standing up, the percentage of body fat is influenced by the
supply of water. And when you measure yourself at different times of the
day, you will also realize a slight difference between the measured data.
With this method measurements under consistent conditions (same time of the day and
same measurement conditions) will lead to best results.
