Under-Rotation Meaning in Diving

Under-rotation occurs when a diver fails to finish their spin before entry. The athlete hits the water before reaching a perfectly vertical 90-degree line. This technical error results in a large splash and point deductions. It often happens if the diver kicks out of a tuck early. The body enters the pool at an angle leaning away from rotation. One example of under-rotation is a short entry on a somersault. Judges look for a straight line from the hands to the toes. This mistake suggests a lack of height or poor spinning speed. The athlete must use their core to hold the position longer. Precise spatial awareness is required to judge the distance to the water. Coaches use video review to help divers fix this common mistake.
