Visulizing the form, I think, is an important
part of learning to throw. We see it in our minds and
do thousands of mental repetitions which when
coupled with practice helps in directing us to throw
hopefully with better form.<br><br>When I threw the
visualization was an analogy to a whip where the body was the
base and the shoulder/arm the end. <br><br>I also
thought that to acheive this the hips should be 90
degrees to the line of throw at the moment the block
occurs and the whip was in a vertical plane.<br><br>In
contrast the current throwers, at least from the pictures,
available to me thru this forum, seemed to indicate that
the hips should remain back until after the block and
then rotate with the shoulders into throwing position.
To me this did not appear to allow for maximum
shoulder speed since in that position the shoulder would
only go as fast as the body turn because the body did
not "C" until the hips were forward at which point
the shoulder was already on the same vertical plane
as the body. Because of this centirfugal effect the
throw generally went side arm. This allowed for much
power but not maximum shoulder speed.<br><br>On the
other hand with the hips forward at the block the body
could "C" meaning the hips were out and the shoulder
back ready to be driven forward with the arm traveling
over the shoulder in an effective whipping
action.<br><br>And then I had the oppurtunity to see videos where I
could stop action the throw of Zelenzy and realized
that maximum speed of the shoulder and arm could not
be obtain with the hips full front.<br><br>Basically
the whipping motion should not be vertical but
horizontal. The image should be the shoulders on a vertical
plane rotating around the axis of the body the center
of effort of which is vertical. To rotate the upper
body (ie the shoulders) it is not just a pull of the
left and separate explosion of the right but rotation
where the same amount of energy is moving each
side.<br><br>Thus the whip effect starts with the shoulder movement
and follows into the arm. With this rotation 2 things
are possible. 1. speed increases. The rotating of the
shoulders alone, the lower body is rotating at a slower
speed at the block, can be several times the speed
available to the thrower when done in conjunction with the
body and also much faster then is possible with the
hips forward at the plant.
