The elbows extend, pushing the upper trunk away
from the floor, but the pelvis remains where it
was in the starting posture. Thus there is an acute
extension of the trunk on the pelvis (probably
in the lumbar region) and the cervical spine is
acutely extended and not rotated. The hands lie
anterior to the shoulders.
The subject then makes a supreme effort to get
the pelvis off the floor, but can only achieve
this by flexing the hip joints so that the feet
are no longer in alignment with the trunk but lie
anterior to it. The trunk is no longer extended
on the pelvis and the cervical spine is flexed
as if the subject is trying to see if the pelvis
has come off the floor.
Finally
the subject collapses noisily onto the floor
again, the elbows buckle into flexion and
rest on the floor, the feet slide as the hips fall
into extension. The thighs roll into lateral rotation
so that the feet are turned outwards. The head
rests on the side of the face again so that it
is rotated to the left – as in the starting
posture. The subject goes limp; the entire activity
cannot be called smooth or well co-ordinated and
has exhausted the subject.

The performance of the subject is
now excellent. The starting posture is the same as
in the first recording, but the ensuing movement
is smooth and demonstrates strength and co-ordination.
The elbows extend and the head, trunk, pelvis
and knees are raised from the floor. As this occurs,
the knees, which are very slightly flexed, pass
into full extension and the subject is supported
by his hands and the balls of his feet only. The
body is inclined in a straight line and the head
is no longer rotated to the left, but is in alignment
with the rest of the body.
The subject then returns to the starting position
smoothly within three evenly spaced intervals.
There is no sudden collapse and no appearance of
exhaustion at the end of the movement.
