I'm curious to know by what age it is reasonable to expect a female gymnast to acquire this skill.
I may have inaccurate information, but I did hear that the double back is more dangerous than double twisting skills. I heard that it is not competed in cheer competitions for this reason.
Since this is tagged with Hopes/TOPS I assume you’re only asking about those pursuing Elite?
Mine isn’t, but she was 12, level 9, FWIW.
I think we have never had kids under the age of 12 compete double backs in this whole country. Many of the juniors (girls born 2005-2003) didn't even do it in the Nationals this year. I would be super impressed to see a 10 year old throw that skill in a routine! It's a risky skill and can lead to a catastrophic injury, so no need to get rid of safety mats, pits and spotting too early.
