Bulletin 2 - July 2008
Punt kick – Inappropriate technique
Welcome to our bulletin board for July. Avid readers of the
sport pages of our daily papers will have noted the concern expressed
by Mike Sheahan over the ‘brittle nature’ of the ‘Franklin –
Roughead partnership’ (Herald Sun, 14 July 2008) with strike
rates of 50% or less in a set kick for goal. Unacceptable at
this level!
Sheahan states that Franklin ‘…has an obvious flaw in his approach
starting out to his left…’ and approaching in a step-across,
wide and very oblique pathway. We agree with this, which is not
to say that the player should not use an oblique approach but
rather that the curve needs to be more moderate. For precise
detail, see Bulletin 1, ‘Kicking for goal – What approach would
you use?’).
In addition Sheahan comments that Roughead ‘…kicks off just
two or three tentative steps’. His concern is well founded. Research
demonstrates that the energy transferred to a kick with an approach
of 5-7 steps is the same as that transferred with any greater
number of steps. Hence, it would appear there is no advantage
to be gained with an approach exceeding 7 steps. However it should
not be less than five steps. This is primarily due to the need
to transfer sufficient energy from the approach to the kick and
to provide enough time for the player to become well balanced
during the approach.
We are constantly reminded of the lack of basic knowledge that
exists at all levels of the game. For example many coaches persist
with the notion that the ball must be placed on, or guided
to the foot. The same terminology is delivered to young
players who are usually instructed by Saturday morning mums and
dads. We know that in fact the ball should be set with a straight
arm lift to a position around waistband level with the hand cradling
and guiding the ball into alignment with the kicking leg. The
ball is then dropped onto the foot platform.
In scientific terms it is anatomically
impossible to ‘place’ the ball on the foot and impressionable
minds receiving insistent instruction to do so will develop
a mental picture of this inappropriate action that can only
lead to persistent problems later. Therefore
to instruct these youngsters to ‘place the ball’ on the foot
presents misinterpreted or misleading information.
Witness the stop frame of Jonathan Brown on this page. It is
immediately apparent that this player relinquishes control of
the ball at approximately hip height, when the kicking foot is
still well behind the player. The thigh/leg is only just commencing
its journey forward to meet this dropping ball. This is important
in terms of timing the drop with ball/foot contact. Any such
disturbance or mistiming will induce misalignment of the falling
ball.
Look at the image again – the set has this ball falling vertically
nose first and side seam vertical. It will nestle beautifully
onto the instep as the leg whip is completed approximately 0.14
seconds later. Most players achieve this orientation, only if
the little finger of the guiding hand is placed along the side
seam. This grip alone permits sufficient hand/wrist angling (ulnar
deviation) to achieve release with the ball at the correct presentation
angle.
Yes – old habits ‘die hard’. It is very difficult to ‘unlearn’
inappropriate technique once patterning has been established
and ‘relearn’ correct technique. Why not provide the correct
information and teach the correct ball set and drop from the
outset.
