When you "bail" on a snowboard a multitude of nasty things can happen due to the facts that you are strapped to the board and that the board is great at catching snow with its edges. So you may end up tumbling, twisting your joints and spraining muscles in the process.
The question is: once you realised you are destined to fall what is the effective way of minimising the risk of serious injury (or simply minimising the risk of tumbling and/or stopping in an awkward position with a twisted knee)?
One things I saw and tried is to rotate onto your back as soon as possible and slide on your back while lifting the feet with the board up to avoid catching the snow and causing a tumble. Is this safe? How could you get into such position quickly? Is there a better approach?
And please, don't tell me not to fall - I already try not to :)
Bonus: Is there a good technique to quickly recover from a fall? I.e. use the residual momentum of to get up and get going again quickly (if you aren't hurt of course)
