In reply to UKC News:
Beth lists a few sports in the AlpKit write-up (I've seen the feature documentary "Murderball", great film!).
This is worth a read:

I've thought for years that the "free immersion" discipline (using the rope to pull yourself by hand to your target depth, and back up) would be a sport that could suit people with spinal injuries - it's outdoors, it's in water, it's strangely relaxing and has definite quantifiable goals.
I asked on a freediving forum about the possibility, and the response was quite positive, including this link. Just a thought.
Couple of examples for illustration here (these are approaching world-class depths so don't be too daunted!)
I am tenuously involved in UK freediving so if this sounds like something Beth would fancy trying, give me a shout.
Cheers
