[...] back which carries him over the bar, rather than the snap forward.
J ROBERTS: Do his feet always stay ahead of his body?
The first fellow doubled over to meet his feet - his arms were
forward almost touching the leg that went over first. In this
case, however, his feet are always ahead of him. At no time does
he bring his arms up to meet his feet. He throws the body back
away from them.
ROBERTS: His arms are raised though, with his feet,
when his first leg goes over.
His arms are then thrown back to get the lay-over.
The third jump is still different. He jumps forward and rolls
over forward on his belly. The principle is that he carries
the far foot from the bar over the bar first, and then flips his
body over. As he rolls over the bar, the height of his body
never gets much above the level of the bar. He's horizontal with
the bar when he rolls over.
ELLIOTT: On the third jump, as he gets into the air,
he doubles his left knee up into a bend position -
thenas he goes over the bar he gives this extra kick
which snaps his body over at the right moment.
The same as the reverse of the second jump. Notice
he has been cup-shaped before he goes over, and he
then gave the reverse to his body which cleared his
The first was a sheer jump, trying to get the body as far as he
coud off the ground, but in order to carry the body almost
vertically above the bar, it takes a lot more jump than it does
to carry his body flat over the bar, so that he has used much
needed energy. In both the second and third cases, the body goes
over the bar in an almost horizontal position, one on his back
and the other on his stomach.
In all the actions studied so far there has been evidenced an
absolute minimum of excess energy. At no place do the arms and
legs move about unnecessarily. This is an important thing to
remember in animation. Any false move in a piece of animation is
going to jump. It is going to be noticeable, and it's always
the bad things that are seen first. A conservation of energy
calls for a complete cordination of the body forces to changes
of weight. It is this continual manipulation of weight and force
and movement which gives economy. This has been a lesson in
economy. It has been a study of how to do a difficult job in a
simple way. These jumps show the result of years and years of
hard work to find a simple way to do a difficult job; which is
nothing more nor less than good form in sports.
