Fig. 9. Displacement range (A) and minimum and maximum velocity (B) and
acceleration (C) from 7 m s-1 to 17 m s-1 for pitch
(left) and heading (right) movement. For each speed category mean and standard
deviation (displacement) or median and interquartile range (velocity and
acceleration) are calculated from all strides falling into the respective
category. In addition a quadratic function was fitted to the data and is shown
as the dotted line.
