Rotation is performed about the body's longitudinal and lateral axes, producing twists and somersaults respectively. Twists are done in multiples of a half and somersaults in multiples of a quarter. For example, a "barani ball out" move consists of a take-off from the back followed by a tucked 1¼  front somersault combined with a ½  twist, to land on feet. Rotation around the dorso-ventral axis is also possible (producing side-somersaults and "turntables"), but these are not generally considered to be valid moves within competitions and carry no 'tariff' for difficulty.
