Hurdle: This term refers to a gymnastics transition from a run to a tumbling skill, most commonly a round-off or a front handspring. A hurdle resembles a skip. In actual gymnastics competition, the hurdle is done from a full-speed run. For training purposes, a power hurdle is often done where the hurdle is done from a two-foot stand. This term also refers to the transition skill from the vault run to the two-foot landing on the vault springboard or into the round-off in Yurchenko vaults. Hurdle steps onto the vault springboard should be long and low to best transfer running momentum to vault momentum. This is a very critical skill to master for both tumbling and vaulting as it will determine the upper limit of power that can be created.
