| Having ranted above, I realise that I have gone well off the thread... yes, Ki Sik Lee's site is well worth a visit; I have been there a few times and will be back at regular intervals as I digest what i have learned . The irony is that this valuable information is provided free, gratis and for nothing - whereas the 'membership' fee that is taken from us by GNAS doesn't get us anything of the sort.

Flashing up mental image of typical GB shooting line I would guess more than 50% of recurve archers use an open stance. As Meddler said information there if you look. Can get general (english language) coach advice 1to1 with good coaches on AT and Sagi board already. You may complain that don't get this from GNAS coaches but (confirming Meddlers comment about the PR mountain) are there any GNAS coaches around at a high level?

| O.K. .....ermm where do I start.... yeah..O.K. .... the articulated joints of the human body have the ability to move within the three cardinal planes of motion.. the planes of motion are 1. the Sagital plane... divides the body between left and right 2. the frontal (or coronal ) plane... divides the body between back and front 3. the transverse plane ... divides the body between up and down. now..... joints, such as the knees, hips and ankles, although they can move within all three planes, each have a plane of motion in which there is a larger range of motion of the joint than the other two planes. This is refered to as the dominant plane of motion or a joints planal dominance. Still with me ...good One of the key elements in archery is postural stability, ie the ability to remain still when external forces are being applied that disrupt the dymanic position of the centre of mass of the body. When we take up a position on the shooting line with our feet ankles knees and hips 90 degrees to the target, the dominant plane of motion of all the lower limb joints is the sagital plane (stand upright and bend your knees, your knees move in the sagital plane). The largest disruptive effect on the stability of a joint in the dominant plane is a force applied at right angles to the dominant plane of a joint. So.... by adopting a more "open stance" you reduce the angle of applied force to the dominant plane of motion and there fore become more posturally stable. ..... There is of course the matter of the tibial torque converter effect and the influance of the frontal plane axis position of the sub-talar joint .... but I think that's a little acvanced

| What YS said ..... Or on a more practical level try the square and open stances while someone pokes you with a stick.

| Archery Australia had a slightly unpolished coaching manual on the web on the Archery Victoria website. It now seems to have dissappeared from there, but google found a copy of it: http://www.freestate-archery.org/fre...g%20Manual.pdf I've read the GNAS coaching manual and the FITA beginners manual, but personally I preferred this.
