The Biomechanics in Archery Essays - Medical Subject Headings The Biomechanics in Archery Archery is the sport, practice or skill of using a bow to shoot arrows. A person who participates in archery is called an archer or a bowman. 482603937000 Archery has been around for many years, and some sources say for as long as 15,000 years. The first bow created was most likely used for hunting and wasn't used for combat until later, and archery was practiced in every country except for Australia. Archery used to be associated as a lower-class weapon, and was not popular until the Vikings successfully won many battles with a bow as their main weapon. In the 100-year war, the English had started using bows, with even children fighting and training with bows. Since guns were invented, the bow has become less popular and is no longer used in combat. The first guns were not as accurate as an archer and arrow, but could pierce armour. Guns are now a lot better than bows in many ways, and archery is now only used for sporting purposes. There are many different types of archery for recreational activities; target archery, field archery, clout archery and bow hunting. Target archery, or competitive archery, is the most common form of archery and is practiced at an international level, even featuring at the Olympics. There are two types if bows, recurve and compound. Recurve bows are the simpler of the types of bows, featuring between one and three pieces that make up the frame, and a single string. Though not required, many recurve bows are made from wood, and are lighter than compound bows. Compound bows are the modern version of the recurve, and have become very popular in recent decades, both for hunting and shooting. Compound bows use a pulley system that takes strain off of the bow and provides slack for the archer, making it easier to shoot with accuracy. Since muscles fatigue, but bones do not, archers have developed a technique to minimize the amount of muscle exertion and maximize use of bones. To maximize effectiveness of the body, archer's try to line the bow up directly along the bones and joints. This is because if an archer has the bows force through the centre, no muscles are needed to keep the bones and joints in place. This minimizes the amount of muscular effort required from the archer. 3375042160083500 Most the bones in our body are used in archery. Bones give us our shape and our posture. Without the spine and leg bones, we wouldn't be able to stand up straight. Without our arm bones we wouldn't be able to hold the bow etc. bones act as a base for muscles, ligaments and tendons. Ligaments connect bones to bones, and tendons connect muscles to our bones. They all work together to allow us to move. The arm contains 3 muscles, the humerus between the scapula and elbow, and the ulna and radius between the elbow and wrist. Each arm is attached to the scapula (shoulder blade) near the top of ou r ribs on the back, and in the front the arm is attached to the clavicle (collar bone). The bones supply the arm 303022017000 muscles with something to attach to, to allow movement, which is used when holding, drawing and releasing the bow. Other bones that are used near the arm are the phalanges, carpals and metacarpals. The carpals are a set of eight i rregular shaped bone s located in the wrist and meta carpals a located between the carpals and phalanges. . These bones assist the phalanges (finger bones) in pressing, grasping, clipping and clasping objects. To hold the bow and to release the string, the phalanges and carpals and metacarpals are involved with gripping the bow and string, and the arrow, and then releasing the string to let the arrow fly. The legs and pelvis/hips are also used in archery. The legs are attached to the pelvis at the hips. The legs are strong so they can support the rest of the body. The legs consist of the femur, between the pelvis and knee, and the fibula and tibia , between the knee and ankle. these bones are vital for standing and
