Roundoff

A roundoff (also called an Arab(ian) spring) is a move in gymnastics similar to a cartwheel, except the gymnast lands with two feet placed together on the ground instead of one foot at a time, facing the direction of arrival.

[1] It is a gymnastic technique that turns horizontal speed into vertical speed and can be used to turn forward impulse from a run into backwards impulse.

Roundoffs are used by most acrobatic sports, including gymnastics, dancing, and cheerleading.

The roundoff is a gymnastic technique that turns horizontal speed into vertical speed (to jump higher); it is also used effectively to turn forward momentum from a run into backwards momentum, giving speed and power to backwards moves such as flips and somersaults.
