Analysis of compound bow archery techniques

Analysis of the technical characteristics of compound bow archery
1. The technical characteristics of the compound bow are: the initial force of the bow is large, and the pulling force gradually decreases as the cam direction changes and the draw length increases. The back hand of the compound bow adopts the indirect force method of using the release device to open the bow.
2. Inhale before raising the compound bow:
Gently press the inhaled air down to the abdomen, hold the breath as much as possible when opening the bow, and control the symmetrical force before and after the bow is pulled to adjust the breathing.
3. The technical characteristics of the symmetrical linear force control of compound bow archery are: according to the lever principle of the cam of the eccentric wheel group, the bow is opened with a large force, and the symmetrical linear control force after pulling is small. The draw length is fixed by the mutual braking, symmetrical restriction of the main string and the auxiliary string and the limitation of the eccentric wheel group positioning device.
4. The control method of the front and rear symmetrical force of the compound bow: after the bowstring of the compound bow is pulled to the stop line, the front and rear shoulders collapse, the shoulder joints are locked, and the archer who chooses the straight arm for the forearm must ensure that the front and rear symmetrical forces are equal when positioning by the string. After the archer who chooses to bend his arm draws the bow, he usually cannot pull the bow to the string position. Only by slightly bending the front elbow and pushing and pulling the bow arm backward as a whole can the bow be pulled to the string and the back hand position can be achieved. It is important to pay special attention to this symmetrical force control that the body should be kept upright and the appropriate front and back symmetrical force should be maintained during the overall withdrawal of the two arms.
5. Due to its structural principle, the maximum symmetrical force of the compound bow is at the front end of the bow: with the change of the cam direction and the change of the force arm and torque relationship, the symmetrical force of the bow is gradually reduced. This requires the correct selection of a bow that can be drawn and the correct use of muscle strength at the beginning of the bow to avoid sports injuries or damage to the equipment.
6. The characteristics of the compound bow structure determine that the symmetrical force should be moderate: the compound bow is constructed using the principle of cam force reduction of the eccentric wheel group, and the tension control weight after the bow is drawn can be reduced by 65-80%. When controlling 20-35% of the symmetrical force, as long as the symmetrical force used for each arrow is the same, the arrow impact point should be the same.
7. The front and rear symmetrical forces of a compound bow should be moderate after the bow is opened: if the force is too strong, the bow limbs and cables will be over-pressed, affecting the stability of aiming and the flight trajectory of the arrow; if the force is too weak, it will affect the draw distance, and due to the recovery acceleration of the cam lever force, the bowstring will be quickly recovered by the bow limbs, destroying the front and rear symmetrical linear control.
8. The precise aiming technique of a compound bow is: the straight line is centered, the line of sight through the rearview window to see the outer ring of the magnifying glass should be centered, and the aiming point in the magnifying glass should be centered when it is aimed at the center of the target.
9. The symmetrical force control method for precise aiming of a compound bow: Precise aiming is completed under a small control force. After the string is leaned on, exhale and hold your breath to aim, and precise aiming can be achieved. The key technology of aiming is the control of symmetrical linear force. If the linear force is too strong, the arrow shot will be biased to the left; if the control force is too weak, the arrow will be biased to the right; if the force is retracted, the cable will leave the positioning control line and the arrow will be high.
10. The compound bow releases the arrow by a mechanical release device: the compound bow releases the arrow by a mechanical release device, which acts on the bowstring and arrow mouth rope, and shoots the arrow by pulling the trigger or firing device of the release device with the index finger or thumb completely separated from the front and back symmetrical force.
11. The counterweight of the compound bow is the guarantee of symmetrical force control and precise aiming: the role of the compound bow counterweight balancer is to increase the weight of the bow body and increase the stability of the front and back symmetrical force control after the bow is pulled; on the other hand, it can reduce or eliminate the vibration of the bow itself. The reasonable configuration of the counterweight balancer is an important part of the compound bow archery technology. If the balance weight of the bow is too heavy or too light, it will affect the control of the front and back symmetrical force, especially directly affecting the accuracy, stability and consistency of aiming.
