FIG 4.8 A figure will change its
gait to suit the environment it is
moving in.
gait is used when we walk through snow over a few inches deep. This is a
more efficient mode of locomotion, stepping in and out of the water rather
than trying to push through it. As the water gets even deeper, it becomes
increasingly difficult and awkward for the figure to lift the feet out of the
water. At some point it becomes impossible to lift the feet clear of the water.
Before that moment, the walker reaches the decision to stop lifting the legs
as high and returns to swinging the legs forward in the same manner as
the regular walk. However, the water resistance on the legs is such that the
forward movement of the legs is more difficult to achieve and requires more
effort. The stride length may be slightly increased to become more efficient;
in order to increase the power to the legs, the rotation of the upper body will
increase and become more pronounced than in a regular walking gait. As
the water becomes even deeper to a level around the hips, the arms will be
lifted clear of the water, and the rotation of the upper torso will also continue
to become increasingly pronounced. As the water gets deeper still, to about
the level of the stomach, the figure will no longer walk upright but will tend
to lean forward slightly, allowing the figure's weight to be slightly supported
by the water. The arms will be raised even higher and the rotation of the
