Brigid McCarthy posted a comprehensive history of the Produnova vault:
• Of Peril, Progress and Produnovas: Part One
• Of Peril, Progress and Produnovas: Part Two
Post any feedback you have on one of those two posts. Brigid would like to see wider discussion.
My own position is clear.
Multiple front somersaults landing forwards are MOST dangerous in terms of catastrophic injury.
FIG WTC should ban the double front, but not the double front 1/2 out. It’s far safer.
Trampoline for many, many years banned double front and triple front — but not the same elements twisting out. (I believe those skills are not longer banned, though I’ve never seen one in Tramp competition. Every trampoline coach knows how dangerous they are.)
MAG MTC should consider banning the Handspring triple front. (4 forward rotations total.)
