Forward 4½ 109 Meaning in Diving

The forward 4½ 109 is an elite dive featuring four and a half somersaults. The leading digit one signifies that the diver begins the maneuver facing the pool. The second digit zero indicates this dive follows the standard somersaulting style of flight. The number nine specifies that the athlete performs nine half-rotations while in the air. This extremely difficult dive is typically performed from a ten-meter platform for safety. Divers must use a very tight tuck position to achieve the necessary spinning velocity. One example of this dive is a top-tier performance in a world championship. A slight error in timing can lead to an unstable or dangerous water entry. Judges award high points for maintaining a consistent body shape throughout the flight. This maneuver remains one of the most challenging dives in modern competitive diving.
