Round-off 1/1 on, 1/1 off
Round-off full on, full off
Yurchenko 1/1 on, 1/1 off
Yurchenko is commonly used to refer to any vault employing a round-off onto the springboard, though it’s worth noting that technically only vault with a salto after contacting the table are classified in the Yurchenko family. Without a salto, these vaults are only referred to as “round-off” vaults and are classified in Group 1 instead of in Group 4 with the Yurchenkos.
In modern elite gymnastics, this basic version of the round-off vault is what you do when you’re learning how to do a Yurchenko, or as a timer, but it isn’t a common competition vault. That hasn’t, however, stopped them from cropping up all over the code of points. We had three round-off non-salto vaults in the 2012 code, and currently have eight in the 2017-2020 code, despite the fact that none of these vaults have been submitted for naming at a competition. This is one of the few that has been around continuously since the 2006 code purge, though it did suffer devaluing in the 2017 update, losing two tenths to become valued the same as the round-off 1/2 on, 1.5 off. Those sit as the two most valuable of the round-off non-salto vaults, and at just 3.80, you can see why they are so rare.
