Fig. 7.10 Examples of different executions of the “Bend” posture.

Fig. 7.11 Versions 1 and 2 of the “Bend” posture.

In Fig. 7.12, it is clear that the “Squat” position, just like the “Bend” position, was
not, and was not able to be, carried out equally by all subjects. Different executions
have an effect on the position of the markers on the back and equivalently influence
the measurement distances.
In general the back length in the “Squat” position is longer than in the “Relaxed”
position. This is because through the flexion of the spine, the spinous processes of the
vertebrae move away from each other and thus so does the corresponding marker (see
Fig. 7.12). Subject 3 (Fig. 7.12, third from the left), however, performs the position
with a very straight thoracic spine. Therefore the marker points converge in this area.
This leads to a difference of 3.7cm. The shortening of the back length was only seen
in a few subjects. The examples of the “Bend” and “Squat” positions suggest that it
would be useful in future studies to form posture groups. These would allow a
