'The Dead Loop, also known as the Korbut Flip, is a daring and complex move in gymnastics that was once a popular and awe-inspiring maneuver. Named after the Soviet gymnast Olga Korbut, the Korbut Flip was first introduced in the 1972 Munich Olympics. This skill became a signature move for Korbut and inspired many gymnasts around the world.
The Korbut Flip is performed on uneven bars, where the gymnast swings backward from a handstand position, releases the bar, and performs a backflip before regrasping the bar. It is a high-risk maneuver that requires exceptional strength, coordination, and timing.' - VIA https://gymnastgem.com/dead-loop/
