BACK, SHOULDER AND ARM LOADS (3)

In the preceding pages and illustrations, various aspects of the upper body or power unit have been explored, and the loads imposed upon it by the physical weight and draw weight of a bow resolved to a resultant force ‘R’, so that its effect upon the shoulder girdle stability can be understood.

It has also been shown that the actions of raising and lowering the arms sideways coincide with breathing in and breathing out; that muscle antagonism occurs if arm raising and breathing out are attempted simultaneously and vice versa; and that inhalation is associated with tension, while exhalation disposes the body to relaxation. On p. 72 and pp. 90–94, some of the advantages and disadvantages of different draw techniques have been discussed and the point made that observations of a technique from the sagittal and shooting planes alone, without consideration of what actions would be seen best from above, could result in inaccurate analysis.

So far we have considered the advantages of setting up the draw load above the shoulder line, so that the shoulder girdle assembly tends to be positively forced down and towards the spine; this action is supported by the lowering of both the arms and the inner clavicular joint corresponding to exhalation of the lungs to a steady state. The high draw preparation position and draw of Fig. 1, p. 73, could benefit from a more detailed evaluation, similar to that for the ‘T’ draw, and the drawings opposite and on p. 99 therefore show the high draw in the same order and draw development as used for the ‘T’ draw (pp. 93 and 95).

From the primary preparation position, where the arrow is nocked and the fingers placed upon the string, while normal breathing and relaxation take place, the head is turned towards the target with exhalation of the lungs; then, while breathing in, both hands and bow are raised in the shooting plane to about, or just above, eye level, obscuring the target (Fig. 1).

As the lungs near a comfortable capacity, indicated by a slight pressure in the upper chest, the draw action commences with all actions contained in the shooting plane: the upper arms descend at an equal pace and the extended bow arm drops towards the target while the drawing elbow descends in an arc and the head is relaxed back, out of the path of the drawing hand; all the time breath is allowed to escape normally through the nose. As the drawing hand passes the level of the mouth and then the chin, towards the exposed side of the throat, the head returns to its natural position upon the top of the drawing hand with the sighting eye behind the string; at the same time the breath and lung capacity reduce to comfortable level and a relaxed steady aiming state. The draw is complete (Fig. 4).
