Bert’s original theory can be expanded as follows:

In any trampoline skill involving twist, the twist is the easy bit. The difficult bit is creating the right amount of height and somersault rotation to provide enough time spent in the correct body shape to allow the twist to work.

That definition is pretty watertight as it can be applied equally to the extremes of half twist jump or the rudi out triff. To perform a half twist jump the gymnast must indeed be high enough (not very high as it happens) and create the right amount of somersault, which on this occasion, is none. The time to execute the twist is provided by the height, while the straight body shape allows the twist to work. To perform the rudi out triff, much more height is needed to provide enough time to execute the move. The amount of somersault rotation is considerable and the time created by the height combines to allow a straight body shape in the third somersault to enable the twist to work. This may be easy for the coach to comprehend standing on terra firma, but our job is to help the gymnast retain mental composure up to and during that moment of departure from the trampoline.

Before looking at ways to develop twist and assist the gymnast to maintain the right mindset, I will dwell a little longer on the difficulties experienced by our athletes. Many beginners have difficulty with the full twist jump, which is often used to start a compulsory routine at the lower levels. The most common scenario sees the gymnast perform an apparently competent take-off with all the expected style considerations, only to touch down and fall off balance, making the performance of the next skill impossible. This frustrating problem can prove difficult to solve until its source is appreciated. In creating twist during bed contact, the gymnast has inadvertently created a tiny amount of somersault-type rotation. If the jump is very low then the resultant balance loss on touchdown may be manageable, but normally there will be enough height (and therefore time) for the unwanted rotation to manifest into a significant degree of somersault. This is a classic example of an apparent technical problem actually being a perception issue on the part of the gymnast. The full twist is simply a microcosm of all the complex, multiple early twisting skills, making it an essential fundamental skill for the developing World Class performer to master.

A common difficulty gymnasts experience when initiating twisting skills during bed contact is vividly demonstrated in the full twist jump. In this skill, rotation should only take place around the longitudinal (twist) axis, but it is easy for the performer to accidentally create some rotation around the somersault axis at the same time. This will result in the full twist being completed but the gymnast falling over when first contact is regained. By learning to isolate the twisting action through balance and erect posture in this basic skill, the gymnast can
