In-Depth Information
• Front right leg continues to swing forward.
• Front left leg is extended forward in anticipation of contact with the ground.
• Hind left leg is extended fully forward and will be the next foot to make
contact with the ground.
• Hind right leg has made contact with the ground and bends slightly
as it cushions the impact. This is the only point on which the animal is
supported.
The next stage of the run is a transition period between what was described in
Phase Five and the subsequent position outlined in Phase One.
Many animals (mostly those that are the prey of predators) incorporate a leap
within their running action, though such a leap does not normally form a part
of the sequence that is repeated at regular intervals and at a specific moment
within the action. Rather, the leap forms an occasional part of the run as part of
a flight response. The irregular timing of the leap within the run probably assists
the animal in evading capture. However, when an animal is being pursued by a
predator, an exaggerated leap may actually be a disadvantage if it is not timed
properly, because it may actually slow down the run. Gazelles will often leap
high in the air as a response to the presence of a predator prior to the chase
commencing. This kind of leaping may be done in part to demonstrate the
animal's agility to the predator with a view to dissuading it from the chase.
Pacing
The transition from a walking gait to pacing involves a change to the
sequence of leg movements. Walking camels demonstrate the same sequence
