RELEASE:

        The release is accomplished by the gradual straightening of the three fingers holding
the string. Try not to jerk the fingers loose from the string, pull to the right, or permit the
string to creep forward before the final release. The string must be released at the anchor point
and not somewhere out in front of or to the side of it. Roll the fingers off of the string; they
should return and brush the neck in their backward movement. The smoother the fingers roll
off, the better the shot.


POSSIBLE ERRORS IN AIMING AND RELEASING:

1. Shifting position.
2. Relaxing both arms and shoulders at the moment of the releasing.
3. Not coming to the point of aim before releasing.
4. Having the point of aim to the right or left of a line directly between the archer and the
       center of the target.
5. Choosing the “wrong arrow.”




Arrow Launch Study

This is a series of frames from a video sequence. It offers a visual perspective on arrow spine.
Often discussed in archery circles but seldom optimized via direct observation (ie: watching
and analyzing arrow as it leaves the bow), correct arrow spine is extremely important in
optimizing any archery system.

RELEASE AND FOLLOW-THROUGH

Each of the top archers has perfected his own style of release. For the new archer it is easier to
concentrate on opening the bottom finger first to avoid hanging up. In fact, if the archer will
bend his three fingers as if he were going to pull the string, he will find he can open the top
finger without moving the bottom two, but if he opens the bottom one first, all three go
together. The follow-through is maintaining good form until arrow hits or passes target, to
avoid throwing the arrow.

Releasing the arrow properly is the most important fundamental in shooting. To follow
through simply means to hold the release position until the arrow is safely launched onto the
target. The key elements of success are: (1) Relaxation (2) and concentration. Here is a
example of a good follow through: (1) The fingers on the bowstring hand are relaxed, (2) head
and eyes are turned toward the target following the flight of the arrow,(3) the bow arm is
extended toward the target, and (4) the bow hand is gripping the bow with the help of a sling.
The bow sling is designed to help the archer during the release and follow through. There are
three basic types of bow slings available (finger, wrist, bow). Any one of the bow sling will
help the archer keep the bow from falling to the ground after the release.

The elbow of the bowstring arm should not extend appreciably after or during the release. The
natural recoil reaction will occur after the release, but the beginner should avoid the habit of
trying to release the arrow by hyper-extending the wrist or roll off the fingertips under its own
pressure.

A. Tighten back muscles

From this point on, it's basically time to shoot your first arrow. Tighten your back muscles
and draw the bow string. Keep your back and arms straight at the target. Like any sports.
Archery also requires some muscle strength. Exercise regularly to improve your strength in
both arms and back. This could help in improving beginners physical strength which will help
them draw. In addition, whether you shoot with fingers or a release, proper back tension is a
key part of proper shooting form. So, how do you create good back tension? How do you get
it to happen and why is it necessary for shooting good archery shots? Back tension, once
begun, never stops or decreases until the shot has been released.

Reaching optimum draw length or optimum draw position is a prerequisite of proper back
tension and must also be the focus of each preceding part of the form sequence. If you don’t
set up properly for back tension execution, you won’t achieve it consistently.

Once you reach your anchor point, don’t stop maintaining back tension. Keep pulling with
your back/shoulder muscles. You must continue back tension throughout the shot sequence.

In the optimum draw position both shoulders are set level with each other, the bow hand and
bow arm muscles are relaxed. The draw hand wrist is straight and relaxed, as are the forearm
and biceps muscles. The draw-side elbow is held level or slightly higher than shoulders in
preparation for final back tension execution. A touch is established between the draw hand
and some part of your face, jaw or neck. This touch is secondary to the establishment of
shoulder position and should not be overemphasized or become the primary focus of your
shot sequence.
The great advantage of back tension is that it uses short muscles. Using short muscles is more
consistent than using longer, larger ones. Using rhomboid muscles allows you to relax your
less consistent arm muscles, which increases accuracy and endurance. Using your body more
efficiently than the competition is how you become more successful in archery.

B. Relax draw hand to release

Keep your bow hold easy and relaxed. Never grip the bow too tightly. Your palm should only
gently touch the nock. This could also reduce fatigue.

C. Keep bow arm up and steady

Once the arrow is released, you must still keep both of your hands and arms steady even after
the release of the arrow, otherwise, the arrow might not be accurate after the release.

As a new archer evolves, he/she might find new techniques and skills. These recommended
techniques are based on generally accepted practice. Various champions have used different
techniques. What is essential is that the shot sequence be duplicated shot after shot. In
archery, consistency is the name of the game.



Common mistakes: Poor Release & Follow-Through. It is common for inexperienced archers
to turn into a spectator for his own shots, throwing his bow arm violently out of the way to
watch the arrow. Students also sometimes throw their hand off the string to the side or
forward (towards the target) - you can see those arrows droop in a graceful arc, landing in
front of the target. Explain that the release happens when you are aimed at the target and
keeping the elbow coming back as the fingers relax off the string (or say that "the string pulls
the fingers open"). Explain that the shot is not over when the string leaves the fingers. They
should keep position until the arrow hits. Try putting your finger lightly on the student’
drawing elbow, guiding it gently back while observing whether he relaxes the back of the
hand.
In summary ,



                  Keep pulling the shouder
                   blades towards each other,
                   while relaxing the fingers of
                   the draw hand
                  A relaxed bow hand will
                   automatically move
                   backwards
                  Relax your bow hand. Let
                   the bow drop.
