Running in between and in- side these tissues and inally penetrating into them we ind nerves, arteries and veins. Organs are located in three cavities: skull, chest cavity, and abdomen. For archery anatomy we may concentrate on bones, joints and mus- cles and leave out the other structures mentioned, they are of more interest in sports physiology. Muscles can only pull and bring two points origin and insertion through which they are atached to the bone closer together. We refer to the origin as the ixed point and to the insertion as the moveable point.

What really happens is there a subconscious movement of the trigger inger or not? Another way to use a mechanical release is to keep up Low grip back tension and use the trigger inger, no mater if wrist-strap release or hand-held release is used, like a rile shooter, shall mean consciously bend this trigger inger on purpose when everything is done right and the archer feels ready to let go.

Super slow motion pictures have shown that the ingers are almost immediately slightly bent again when the string has moved forward just a few centimetres. With a hand-held release, for example a thumb release, most probably the ingers holding the f Some coaches recommend a square classic stance, mechanical release will open slightly or, also thinka- others an open one.

Novice archers will typically shoot a soft cam whereas a more advanced archer may choose to use a harder cam to gain speed. Bows can be had with a variety of cams, in a full spectrum from soft to hard.

Some pulley systems use a single cam at the bottom of the bow and a round idler wheel at the top of the bow instead of two identical cams. This design eliminates the need for a separate control cable and instead uses a single long string that begins at the cam on the bottom of the bow, travels over the wheel on top, and back to the bottom cam.

A separate buss cable then connects the bottom cam to the top limb. When a compound bow is drawn, the limbs are pulled in toward each other by the cables, unlike a longbow or recurve where the limbs flex in the direction of the bow string. This difference allows modern compounds to have limbs that are closer to horizontal instead of angled. The horizontal, or "parallel" limb configuration minimizes the recoil and vibration felt by the shooter when the arrow is released, as the forces going upward at the top limb and downward at the bottom limb cancel each other out.

The pulley system will usually include some rubber-covered blocks that act as draw-stops. These provide a solid "wall" that the archer can draw against. These draw stops can be adjusted to suit the archer's optimum draw-length, which helps the archer achieve a consistent anchor point and a consistent amount of force imparted to the arrow on every shot, further increasing accuracy.

Dry firing is more likely to damage or destroy a compound bow due to the greater amount of energy stored and released. Unlike traditional bows, replacing the string or cables or making adjustments to let-off or draw length often require a bow press, a specialized tool used for compressing the limbs, taking tension off the cables and string.

Circumstantial advantages[ edit ] Compound archers often use a mechanical release aid to hold and release the string. This attaches to the bowstring near the point where the arrow attaches, the nocking point, and permits the archer to release the string with a squeeze of a trigger or a slight increase of tension.

It called synergists. If a single muscle agonist is contracted is possible to raise the arm sideways we call that abduc- the antagonist has to relax and vice versa. If that does not tion almost to the horizontal level without involving any work properly it will result in cramps where almost no movement of the shoulder blade itself.

Further abduction intended movement can be achieved. Dislocation of the up- per arm out of the socket at such generous movements is avoided through the rotator cuf, a strong capsule around the joint. To be able to stand straight or to keep our body in a bal- anced posture, no mater if standing or lying down, mus- cles have a certain basic tension which can consciously be inluenced and altered. If, through exercises, one muscle is well trained the antagonist will become relatively too weak; such an imbalance is then followed by a change in the usual joint posture.

Knowing this, we should always recommend strengthening not only the agonist but also the antagonist, as well as symmetrically both sides of the body, to keep the balance.

For archery, our main concern points towards bones, joints and muscles of the shoulder girdle.
