In-Depth Information
The left arm begins to move forward as the shoulder rotates. The bend at
the elbow and wrist remain. There is slight drag on the hand.
The body remains upright.
Phase Three: The Passing Position
The left leg now takes the entire weight of the body. It is straightened
at the knee and held in a completely upright position directly below the
torso.
The right leg has swung forward to its position alongside the supporting
left leg. The knee bends increasingly to ensure that the foot clears the
ground.
The right arm continues to swing backward; the elbow remains slightly
bent, with the forearm extending in front of the upper arm.
The left arm moves forward and is now positioned alongside the body. The
elbow remains bent and the hand is located directly below the shoulder.
The body, head, and hips have risen to their highest positions in the walk
cycle. The supporting leg and the torso are vertically aligned.
Phase Four: Stretch
The left leg now begins to extend backward and is positioned slightly
behind the body; the knee remains straightened.
The right leg swings forward. A bend in the knee means that the lower leg
moves ahead of the upper leg in anticipation of the foot contacting the
ground.
The right arm moves backward, with the elbow and forearm extending
behind the body. The right shoulder rotates backward.
The left arm continues to swing forward ahead of the shoulder, which also
rotates to a forward position. The bend in the elbow increases slightly.
The body begins to fall forward from its highest position in the cycle.
Phase Five: The Stride
The right leg is thrown completely forward; the foot has just made contact
with the ground and the knee has straightened.
The left leg is extended backward behind the body and there is a bend
in the foot as it prepares to be lifted from the ground. The knee is
straightened.
The left arm is now in a forward position, with the forearm held in front
of the body, a slight bend in the elbow, and the left shoulder rotated
forward.
The right arm is extended backward prior to it moving forward. There is a
slight bend at the elbow and wrist. The right shoulder is rotated backward.
The body once again reaches the lowest point in the cycle, with the angle
between the legs placing the hips closer to the ground.
It is important to realize that the sequence described here makes up only half
of a complete walk cycle. The second half simply reflects the first, with the
opposite limbs undertaking the same actions with the same timings.
