Landing
Preparatory Phase
The resulting phase of the takeoff is quickly followed by another action that
may be considered a second preparatory phase as the figure swings the legs
forward in anticipation of landing. The torso straightens and the head rotates
to maintain its horizontal orientation.

Execution Phase
The legs are extended ahead of the torso, and as the feet make contact with
the ground they quickly flatten from their initial contact point on the heels.
The knees then begin to bend, acting as shock absorbers.
Recovery Phase
During this part of the action the figure returns to its original standing
position and once again is at rest.
Cyclical actions may have another distinctive phase—the return phase—as
the figure moves back each time to a position that preceded the preparatory
phase. Actions that have a clear beginning and end, such as a chopping
action, clearly demonstrate this phase. However, in some cyclical actions that
are more or less continuous, such as a walk cycle, a return phase is not evident
because there is no distinctive start position.
As we have discussed elsewhere in this text, identifying the primary,
secondary, and tertiary elements of an action, along with the separate phases,
will go a long way toward providing us with a thorough and proper analysis of
an action.
