STEP 6 FULL DRAW, ANCHOR and STRING ALIGNMENT ALIGNMENT
SECTION 16 STEP 6 FULL DRAW, ANCHOR and STRING ALIGNMENT FULL DRAW At full draw, the elbow of the drawing arm should be in line with the shaft of the arrow, the back of the drawing hand flat, three fingers in contact with the string and the bow arm straight with the elbow rotated away from the bowstring. BODY ALIGNMENT The student should be standing upright, with 60% to 70% of their body weight distributed forward on the balls of their feet and 40% to 30% on their heels. From a front view the student should be standing upright and should not be leaning back or forward. It is common for students to lean back, taking the majority of their body weight on their back foot. Their spine should be straight and their head directly over their spine.

Ideally the body’s centre of balance should be centred in a line below the archer’s spine toward their feet By not standing straight and keeping the spine straight, long term this can cause injuries as well as affect the archer’s development. -
Topics on Archery Mechanics Joe Tapley
Topics on Archery Mechanics Joe Tapley Topics on Archery Mechanics Introduction The basic physics of archery has in principle been understood for around 80 years. The last topic to be theoretically described was vortex shedding (aerodynamics) in the 1920's related to developments in the aircraft industry. While the principles of archery are understood, in practice the behaviour of the bow/arrow/archer system (termed 'interior ballistics') and the arrow in flight (termed 'exterior ballistics') are somewhat complicated. In order to understand the mechanics of archery computer models are required. Models related to interior ballistics have been developed over the years becoming more realistic (and complex). A few related papers are listed below: Kooi, B.W. 1994. The Design of the Bow. Proc.Kon.Ned.Akad. v. Wetensch , 97(3), 283-309 The design and construction of various bow types is investigated and a mathematical model is used to assess the resulting effects on the (point mass) shot arrow. Kooi, B.W. & Bergman, C.A. 1997. An approach to the study of Ancient Archery using Mathematical Modelling. Antiquity, 71:124-134. Interesting comparison between the characteristics and performance of various historical and current bow designs. Kooi, B.W. & Sparenberg, J. A. 1997. On the Mechanics of the Arrow: Archer's Paradox. Journal of Engineering Mathematics 31(4):285-306 A mathematical model of the behaviour of the arrow when being shot from a bow including the effects of the pressure button and bow torsional rigidity. The string forces applied to the arrow are derived from the bow model referenced above. -

Editorial by Morten Wilmann, Chairman Dear Judges, When writing this editorial we are just up front of the Olympics. For judges on duty for that event, it is starting to be a bit thrilling. Some athletes are saying that this “is only one event like other events”, and some may regard it as such (although I doubt if they manage). In spite of recent news about extensive doping in some sports and in some countries, I still think that the Olympics stands out as a very special event, well regarded and connected with “personal glory” for the winners. Archery in the Olympics 2016 – in Rio de Janeiro, Brazil – takes place in the famous street of the Sanbodromo where the carnival regularly takes place, again a rather iconic place for archery. These are surroundings that may add some thrill to the competition, and your committee is confident that our judges will perform at the same top level as the archers – in spite of the possible stress of the moments.
