Which jump requires the gymnast to perform a full twist in the air?

The jump that requires the gymnast to perform a full twist in the air is the BB jump 1/1. This terminology is specific to gymnastics, where "BB" stands for balance beam, and the notation "1/1" indicates a full twist. In this particular jump, the gymnast executes a complete rotation while in the air, showcasing not only their aerial awareness but also their technical ability to control the body during the twist.

This skill is assessed for its difficulty and execution, as a full twist increases the complexity of the jump. The performance of a full twist not only enhances the routine’s aesthetics but also contributes to the overall difficulty score when judged, making it a significant element in balancing skills on the beam.

Other jump variations listed, such as the tuck jump, straddle jump, and sheep jump, do not involve a full twist, focusing instead on different body positions and aesthetic qualities, which do not demand the same level of rotational skill. The designation and complexity of the BB jump 1/1 set it apart, affirming its recognition as a more challenging jump in Level 10 gymnastics routines.
