How
to Hold the Discus
The first step in introducing
the discus to the beginner is to give them a feel for how to hold
the discus. To begin, the thrower should hold the discus in the
palm of their outstretched arm (this is the non-throwing arm). Then
place the right fingertips extending over the edge of the lip of
the discus. Each finger should be spread apart. This should give
the thrower an idea as to how the discus should feel in their hand.
The coach should make sure that the thrower is not gripping the
discus, but that they are lightly supporting the discus in their
hand.
Next, the thrower should
hold the discus in their hand while their arm is dangling straight
down from the shoulder. Here again, the coach should make sure that
the thrower is not gripping the discus, but that the last joint
in each finger is wrapped around the edge of the discus. The thrower
can now start swinging the arm back and forth like a pendulum. This
will give the thrower a feel for how the discus should feel in the
hand, while the hand is moving. The centrifugal force generated
by this swinging motion will help keep the discus in the thrower's
hand and should reduce the thrower's need to want to grasp onto
the discus.
Teaching
the Release
After the beginner has
gotten used to the proper way to hold the discus, they are now ready
to learn the release. Many times, when a beginner is asked to release
the discus, he will throw the discus out the "back" of the hand
instead of the "front". An easy way to teach the proper direction
in which to let go of the discus is to have the thrower hold the
discus by the waist, as described in the previous paragraph. From
this position the thrower will tilt the hand backward and let the
discus roll out of the hand and fall onto the ground. When this
happens, the discus should roll forward off each finger, starting
with the pinky and ending with the index finger. The coach should
make sure that the discus does not fall out the "back" of the hand,
causing it to roll off the index finger first and the pinky last.
The next step in teaching
the proper release of the discus is to have the thrower bowl the
discus. This drill can be done with a partner who should start by
standing roughly ten yards apart from the thrower who is about to
bowl the discus. This drill is fairly easy since it requires the
thrower to just roll the discus on its edge, to his partner as if
releasing a bowling ball down a bowling alley. The partner in this
drill can then bowl the discus back to the other partner to complete
the drill. as the throwers get more proficient at this drill, they
can increase the distance between themselves and work on releasing
the discus with a little more pace.
Another type of release
drill is an advanced variation of the pendulum drill. the thrower
will start this drill by swinging the discus from a dangling arm,
as previously described. As the thrower's arm is swinging forward,
he will release the discus out the front of his hand, which will
cause the discus to be thrown straight up in the air. The coach
should make sure that the discus has a good amount of rotation on
it, and that the discus lands on its edge when it comes back to
the ground. It is important that these two things occur because
they are indicators for a proper release.
The next step will have
the thrower swing the discus back and forth in a place that is parallel
to the ground. This poses a problem for many beginners because they
are afraid that the discus will fall out of the hand as they are
swinging the discus. During this exercise, their tendency will be
to grab onto the discus instead of letting the centrifugal force
generated by the swinging motion, hold the discus in the hand. To
begin this drill, the thrower will hold the discus in the outstretched
palm of the non-throwing hand, while the throwing hand is placed
on top of the discus. The grip should be the same as described in
the first paragraph. The thrower will then swing the discus back
into the palm of the non-throwing arm. As this drill is being performed,
the thrower should make an effort to keep the throwing hand on top
of the discus while swinging the arm and not turn the discus over
so the hand is underneath the discus. This drill should be repeated
many times in succession with no pause between the direction changes
on the throwing arm.
Standthrow
from a Kneeling Position
Once the thrower is comfortable
with swinging the discus back and forth, and is able to do this
without "cupping" or grabbing the discus, they should be ready to
work on an actual throw. The first drill that can be introduced
that involves an actual throw, is a standthrow from a kneeling position.
Throwing from a kneeling position may seem strange but it serves
to reduce the power that can be achieved by the thrower, by eliminating
the legs from the throw, which in turn will reduce the possibility
of an errant throw. It also serves to focus on the upper body's
role in the throwing action. This will allow the thrower to concentrate
better on the arm action of the throw.
To begin this drill,
the thrower should assume a kneeling position on one knee, with
the left foot forward and the right knee supporting the body weight.
The thrower then takes the discus and swings it back as he relaxes
and stretches the throwing arm during the back swing. The coach
should make sure that the thrower rotates the trunk backward, along
with the throwing arm, so that the whole upper body stays "in contact"
with the discus. Once the arm has been pulled back as far as possible,
the thrower should "pull" the discus through by turning the trunk
and pulling the arm forward. The release should be flat and the
discus should land flat against the ground anywhere from 15 to 45
feet in front of the thrower. If this drill is performed properly,
the discus should slide to a halt at some distance directly in front
of the thrower. Once again, the coach should make sure that the
discus is coming out of the thrower's hand properly and that it
has the proper flight and rotation.
The
Standthrow
When the beginning thrower
is able to perform all of the previously mentioned drills, he should
be able to make the transition into the standthrow with relative
ease. To introduce the proper position for the standthrow, the coach
should have the thrower stand in the front of the discus ring facing
the entire body out toward the center of the sector. From this position,
the thrower steps his right foot back in toward the center of the
discus ring so that the feet are a little more than shoulder-width
apart and the right heel is lined up with the left toe. The thrower
should then bend the right knee and shift his weight back o the
ball of the right foot. At the same time, the thrower should swing
the discus as far back behind his body as it will go, which will
usually be a position back over the left heel. From this position,
the thrower will immediately initiate the throw by pivoting the
right foot, which will then cause the right hip and shoulder to
rotate through. This action will cause the throwing arm to be whipped
around and the discus will be released, as in the previously described
release drills.
The coach will also want
to look for the following things when the thrower is performing
the standthrow:
1)
The thrower pivots on the ball of the right foot during the throw,
and finishes the pivot with the right foot pointing in the direction
of the throw.
2) The left leg (i.e., block
leg) straightens out to form a solid block as the discus is being
swung around to be released. The block is caused by a sudden deceleration
of the left side of the body, which in turn will cause an acceleration
of the right side, thus accelerating the discus as it is being released.
3) The orbit is the path that
the discus follows as it is being thrown. The orbit of the discus
should follow a high-low-high pattern. This means that the discus
will be at its highest point as it is fully drawn back (i.e., when
it is over the left heel). The discus will hit the lowest point
in its orbit when it is passing by the right foot. From this point,
the discus will start to rise back up to its high point as the throwing
arm is brought around to release the discus.
4) The head should always be
facing straight away from the chest during the throw. make sure
that the thrower does not turn his head away during the release.
The head should actually be thrown back during the release to allow
the chest to get up into the throw.
The
Half-Turn
Once the standthrow has
been mastered, the beginning thrower can progress to the half-turn
drill. This drill teaches the fundamentals of pivoting on the right
foot in the middle of the ring and it is a technique that can be
used in competition. The thrower can actually begin this drill without
the discus so that he can focus attention on the pivoting action
of the right foot and the turning of the body. The thrower should
start this drill with the right foot placed in the center of the
ring with almost all of his weight bearing down on the ball of the
right foot. The right leg should be bent as it is at the beginning
of a standthrow. The whole body should be lined up in a position
similar to that at the beginning of a standthrow, except that the
thrower will be lined up to throw out the back of the ring. It is
also suggested that when the thrower is performing this drill without
the discus, he has both hands on the hips to minimize the use of
the upper body to gain rotational momentum.
Once the thrower is comfortable
with the starting position for this drill, he begins by rotating
the right hip, knee, and foot in unison to cause the body to start
rotating around. The body of the thrower will be balanced over the
ball of the right foot, which will be pivoting as the body turns
180 degrees to the standthrow position. At no time should the heel
of the right foot touch the ground. While the right is pivoting,
the left leg should be pulled close to the right leg, causing the
knees to almost touch together in an effort to increase the speed
of the body's rotation. As the thrower is finishing his 180-degree
turn, he will shoot the left leg out into a straightened-out position
that is similar to that seen at the beginning of the standthrow.
At the end of the 180-degree turn, the coach should take note to
see that the thrower has maintained the following positions:
1)
The feet are in heel-toe alignment.
2) The thrower's back is facing
the throwing sector and the chest is facing toward the back of the
ring.
3) The thrower's weight is balanced
over the ball of the right foot (i.e., the pivot foot).
4) The right leg is bent and
the left leg is almost straight, while slightly flexed. The thrower
should be in a position to deliver a solid standthrow.
Once the thrower is able
to master these positions following a 180-degree turn, he can advance
to a series of half-turns to solidify the right foot pivot. The
next step is for the thrower to perform this drill with the discus
in hand. This can be done without releasing at first, by either
holding onto the discus as he turns, or by taping the discus to
the hand. The final step is to perform this drill with a release
at the end. It is important for the coach to emphasize the smooth
transition from the half-turn to the throw. The thrower should not
be stopping or stalling after the half-turn before going into a
release. The coach should also make sure that the thrower does not
initiate the half-turn with the upper body, which is usually the
most common fault for beginners with this drill.
The final important detail
that the coach should note for this drill is maintaining the proper
orbit of the discus. The thrower should start the drill by swinging
the discus backward, at hip-level, and then pushing it forward as
the half-turn is initiated. As the thrower starts the half-turn,
he directs the discus in an upward path so the discus reaches its
high-point when it is closest to the front of the ring. By doing
this, the thrower ensure sthat the discus has established its proper
orbit with a high-point when the discus is near the front of the
ring and the low-point when the discus is positioned close to the
back of the ring. The proper orbit enables the thrower to release
the discus as it is ascending towards the high-point of its orbit,
which in turn will cause a nice parabolic flight.
The next drill that the
beginning thrower should attempt once the half-turn is mastered,
is the step-in. This drill begins
with the thrower standing in the back of the ring with the ball
of the left foot placed inside the back edge of the ring. As with
the half-turn, the thrower should start this drill without the discus
and with both hands on the hips to minimize the use of the upper
body to gain momentum. To begin this drill, the thrower steps with
the right foot into the center of the discus ring and settles his
weight down onto the ball of the right foot. At this point, the
thrower should be in a position similar to the starting position
for the half-turn drill. The thrower then proceeds to perform the
half-turn and throw. As the different parts of the step-in drill
become more comfortable, they can be molded into one complete movement
with no pauses between positions. It is essential that the coach
makes sure that the heel of the right foot never touches the ground
once the full step-in drill has begun. The emphasis of this drill
should be the continued pivot of the right foot. It is also important
that the coach makes sure that the thrower initiates the 180-degree
turn by pivoting the right foot. The general rule of thumb is that
you pivot to get into position to throw and not to pivot as a reaction
to the throw. The coach should also make sure that the thrower holds
the discus low behind the right hip as he steps into the center
of the ring.
The next drill that follows
the step-in is the South African drill.
This drill begins just like the step-in except that the thrower
drives the right leg into the middle of the ring as he pushes off
with the left leg to generate power out the back of the ring. This
is an excellent drill to teach the thrower how to drive across the
ring using the leg drive from both the right and left legs. With
this drill, it is important that the coach is careful to make sure
that the beginning thrower does not initiate the start of the throw
with the upper body, which is the tendency of a lot of beginners.
The coach will also want to check for the following things:
1)
The thrower keeps the upper body relaxed as he leads with the right
leg into the center of the ring.
2) The thrower pushes off with
the left leg out the back of the ring as the chest is facing the
right sector line. At the same time, he will sweep the right leg
outward and then across the body as it is driven toward the center
of the discus ring. These points are extremely important to remember
to make sure that the thrower does not over rotate out the back
of the ring. Many throwers mistakenly wait until they are lined
up facing toward the center of the ring before they drive toward
the front of the ring. When this occurs, the sweeping action of
the right leg causes them to land about a foot and a half to the
left of where they are trying to drive. This will result in over
rotation. This is why the thrower should drive down the right sector
line, to compensate for the sweeping action of the right leg, which
will cause him to land in the center of the ring.
3) The thrower should land in
a balanced position on the ball of the right foot near the center
of the discus ring.
4) The thrower should always
be on the balls of the feet during the throw.
5) Make sure the discus follows
the proper orbit, with the low points being when the discus is closest
to the back of the ring and the high point being achieved when the
discus is closest to the front of the ring.
Once the thrower is able
to perform the South African drill, he is ready to attempt a full
throw. Before attempting a full throw, there is one drill that can
be used to introduce the turn out the back of the ring. This is
called the 360-degree turn drill.
As with the 180-degree turn drill, the thrower can perform this
drill without the discus and both hands on the hips in an effort
to eliminate the upper body from initiating the turning movement.
This drill begins with the thrower standing almost straight up while
having all his weight balanced on the ball of the left foot. The
feet will be slightly wider than shoulder-width apart with the left
leg slightly flexed while the right leg is only slightly bent. From
this position the thrower pivots in a complete circle on the ball
of the left foot and comes to a stop in the original starting position.
The coach should pay careful attention to the fact that the right
leg should stay wide as the turn is being performed. Many beginners
pull the ankles together in an attempt to gain more rotational speed.
This should be discouraged since this is not how the thrower will
turn out the back of the ring during a full throw.
Getting
Out the Back of the Ring
When the thrower is able
to perform a complete 360-degree turn without much effort, he can
now attempt a full throw. To begin, the thrower lines up in the
back of the ring with the feet on either side of the center portion
of the back of the ring. This position will be exactly like the
starting position for the beginning of the 360-degree turn drill,
except that the thrower holds the discus in his hand behind the
right hip. When the thrower starts the throw, his weight should
be equally distributed over both the right and left legs as he performs
a wind-up with the discus to
gain a little momentum to start the throw. There is really no need
to do more than one wind-up and this wind-up should not be so extreme
as to make the thrower off balance as he begins the throw. As the
thrower starts to come out of the wind-up and turn out the back
of the ring, he should shift all his weight over the left foot so
he can pivot on the ball of the left foot. This will allow him to
turn easily out the back of the ring. Once the thrower has shifted
all of his weight to the left foot and is beginning to initiate
the turn, he should sweep the right foot out away from the ring,
making a wide circular sweep. When the thrower has turned 90 degrees
out the back of the ring, he will find that he is in the starting
position for the South African drill. At this point he should complete
the rest of the throw in the same way he performed the South African
drill.
One of the hardest things
a beginner thrower will have trouble getting used to is having a
balanced turn out the back of the ring. It is critical that the
coach makes sure that his throwers do not initiate the turn out
the back with the upper body, and that they use a driving left leg
and sweeping right leg to generate the impulse to get them across
the ring. The upper body should be relaxed during the whole rotational
process until the delivery phase of the throw.
The coach should make
sure that these technical elements occur during a full throw:
1)
Once the thrower reaches the standthrow position, the throwing arm
will make a 90-degree angle with the torso. This 90-degree angle
between the arm and torso will be sustained through the release
of the discus.
2) The rhythm of the throw will
be from slow to fast (i.e., there will be a buildup of rotational
speed throughout the throw).
A typical throwing workout
may consist of the following for an athlete who is working on the
right foot pivot:
5 standthrows
5 half-turns
10 step-ins
3 South Africans
10 full throws
33 throws total
