I agree with what has been said. Yes spring floor is a safer way to go. No it doesn't guarantee you will not have an injury but definitely minimizes one if it was to occur and could potentially save someone's life more so then if that same injury happened on a cement floor. How do you get this information out there for the people who lack common sense, idk.
Just for the record, and these may be graphic to look at but standing and falling back... Not from like a stunt but just your head hitting the concrete may make your head look like this. Sorry if these pics gross anyone out... Here is my head which I had to get staples in because me being the smart person I am waited several days before going to the hospital lol
The day it happened
The next day.
Now imagine if I was a flyer and fell out of a stunt to a hard ground it would have been crucial.
I think part of this comes with people lacking common sense and the other problem is mistakes happen. It could be that mistake on a round off or that mistake on a full. Same for stunting. I know alot of schools don't have access to this unless practicing at an all star gym or something similar. It would be nice if the state allocated money for the schools like they do for the football field or the band. I know that's not possible and no matter how much we know they aren't going to see it is a necessity and I believe if my daughter cheers in high school 8 years from now she will probably be practicing the same way they do now. In areas not sufficient to help reduce injuries. Football players get all kinds of pads, helmets, and gear to keep them safe. I think even to schools with outstanding cheer teams no one really views them as something to help them improve the way they have been doing it.
