Round-off 1/2 on, front pike
Yurchenko 1/2 on, front pike
The best vault ever
Oksana Omelianchik (SOV)
Criminally undervalued with respect to the Yurchenko full, the Omelianchik has fallen into disuse in the elite world because it’s just not worth it to even bother with a round-off 1/2 on entry unless you’re planning to eventually upgrade to a Cheng.
It’s 10.0 start does, however, make it a golden goose of NCAA gymnastics.
You will often hear round-off 1/2-on style vaults referred to as “Yurchenko 1/2 on,” which is fine, though I don’t use it. The term Yurchenko refers to the round-off vault entry without any twisting in pre-flight. When a half-twist is added, it becomes a different entry that isn’t a Yurchenko. Yurchenko is not a synonym for round-off. It’s a style of vault, of which this is not one.
The valid counter-argument to that would be that using Yurchenko 1/2 on is no different than referring to a skill as a Shaposhnikova 1/2, even though the Shaposhnikova is its own different, specific skill. Which is a good point. Other counter-argument: the round-off 1/1-on vaults are classified in the same family as the Yurchenkos, so why shouldn’t the round-off-1/2 on vaults be? Also a good point. So whatever.
