Exactly. She has a very painful back injury. They tried hard to compensate it, but its impossible. Girls in figure skating often have problems with spins because of back injuries. But they have only 3 spins, while gymnasts had to much more difficult things.Dina has been lowering her BD for years now because she just can’t do the more difficult things anymore. So I’m not sure why are people surprised here. I’m not sure what else they are protesting either.
She didn’t even compete cleanly in her other apparatus. She lost a bunch of ADs, had medium to large faults in BD execution, in routines that weren’t even the most difficult. This result was not a surprise. It had to happen someday.
Dina lost to herself. She was like Medvedeva in Korea. Dina did her best, but it wasn't enough.
