A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw, when it seems that the arrow would have to pass through the starting position it was in before ...
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .
archer's paradox (effect) – The effect produced by an arrow flexing as it leaves the bow; archery (practice) – The practice of using a bow to shoot arrows; arm guard (equipment) – A protective strap or sheath for an archer's forearm (a.k.a. bracer) arrow (equipment) – A shafted projectile that is shot with a bow
But the American archer has redefined the sport, showing that it’s possible to not only hold a bow with one leg, pull the bowstring back with one’s jaw, hold all the tension and potential ...
of the bow (in the case of a right-handed bowmen), in the time the string (and therefore the rear-end of the arrow) moves in the median plane of the bow from full draw to the braced position. The ‘Archer’s Paradox’ consists in the fact that the arrow does fly to its mark instead of along a line represented by its axis in braced position.
LAF1 classified athletes compete in ARW1. [9] [10] Sportspeople in this class use wheelchairs on a regular basis as a result of reduced muscle function. [11]ACSM's Primary Care Sports Medicine defines LAF1 as a medical class as "[s]evere involvement of the four limbs -- for example, MS, muscular dystrophy (MD), juvenile rheumatoid arthritis (JRA) with contractures" As a functional class, ACSM ...
Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.
The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. [14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso.
