FIG 5.63
Continued
Phase One: Preparatory Phase
To lift such a heavy weight, it is important to shift the body position in relation
to the object. In this example, that means placing the body directly over
the weight to minimize the angle and thereby cause less stress on the body.
Notice how the legs are spread apart to create better balance. Stability of the
figure is important, so the feet should be planted flat on the ground. A firm
grip is undertaken, with the arms being held straight.
Phase Two: Execution Phase
Before taking the weight, the knees are bent and the hips dropped. The lift
begins with the initial action of the figure taking the weight. This may be
a small backward movement of the torso, positioning the weight centrally
between the feet. At this point the weight is taken by the arms and the back is
oriented into a more vertical position.
The lift is then undertaken by the extension of the legs. The knees are
straightened and the angle of the femur and the pelvic girdle becomes less
acute. If the lift is to be executed properly with minimum strain on the figure,
the back is held as straight as possible, with the strain being taken by the legs.
As the figure rises into a near vertical position, the arms may then come into
play, lifting the weight to a higher position over the top of the pelvic girdle.
This will place the object in a more central position, making balance more
easily achievable.
Phase Three: Resulting Phase
As the figure rises into the upright position on completion of the lift, it moves
into a position that achieves and maintains maximum balance and stability.
