Not sure how they are stood in the ring, are you in front, on the side, free standing or how but what about associating a word with something she enjoys and likes.
I got one of my girls associating a play with a hose which she loves with "whats this!!!"
Using it to recall her from barking at neighbours dogs with great success and just quick whisper "whats this" gets her attention and stand on her toes (tail starts wagging etc), awaiting a play with the hose even if we are not even outside!
You could use that word in the ring at that crucial moment to get her "pick herself up" for few moments.
If she is food oriented maybe teach her to catch and use a word right before you throw the treat for her...
If she is ball oriented that could work even better, just teach her you do not have the ball in your hand but it will appear after you have said the magic word.
First of course have it in your hand and throw straight away but slowly move it to your pocket and let her stand waiting for few seconds before throwing it for her to catch. if she does not catch things, play of tug maybe?
That should make her pick her tail up, I would think :) and is pretty quick and easy to teach once you figure out that one thing she just loves& gets her excited enough.
