Successful vaults come from mastering certain vaulting components along with personal power. These components are running, the hurdle, board contact, a first flying phase, table repulsion, and a second flying phase. Lack of power or poor technique in any of these vaulting components can result in costly mistakes.
To perform this combination the athlete must have mastered tumbling double fulls, beam back handspring to two feet landings, and progressively learn to connect the back handsprings to back tucks, and layouts to full twist dismounts. The gymnast must also develop an increased in speed and power while practicing those combinations.
To reach this level of front dismounts, as with any other gymnastics activity, the gymnast must progress step by step from the easiest basic skills to the most difficult ones. In the case of front dismounts, they must develop increasing confidence and balance to be able to run across the beam and punch the dismount takeoff. Gymnasts must also get used to punching with one foot in front of the other, and first learn each dismount into a pit until the skill can be performed safely and consistently.
Once a gymnast has mastered a fair layout gainer, they can progress to a gainer full. Gymnasts should start practicing this skill from an elevated surface to a loose foam pit. The gymnast must focus on creating a good rotation during the layout. To create the desired rotation, the gymnast must swing up strongly with the free leg.
The gymnast demonstrating this combination bails over with a little arch to begin the inside endo, but then shows a good compression, and on the swing up and comes out of the skill with the correct hip roll-out action. On the pirouette to mixed grip he again has a slight arch that could be refined to a straighter position and keeps his head slightly out to maintain visual contact with the rail during his pirouette which helps him to regrasp the bar more consistently.
In general, one of the most common learning mistakes of either straddle or inside endo to full pirouette is to swing down crooked after the pirouette. The reason for this mistake is an excess of support transfer to the post arm. The gymnasts shift their weight like they were going to perform the regular front pirouette that they have learned before, and that really requires a support transfer beyond the vertical of the post arm to finish square in a different bar position.
As mentioned before for the endo to mixed grip full pirouette combination, some of the gymnasts' main goals are to clear the rail, to flow from the endo to the pirouette without a large pause, and to swing down square. Notice how the gymnast keeps his eyes on the bar during the full pirouette.
Here are some examples of a Yurchenko Tucked Full.
Observe the yurchenko layout full and check for some of it's weak and strong points. This gymnast dives on her round-off and her turnover to the table is a little too high. On a positive note, as she comes off the table, her arms move down toward the center of mass, helping her twist.
All of the technical actions required to perform the successful yurchenko full become even more important to progress and perform the yurchenko full and a half. The gymnast should always have a straight round-off with a center of mass in front of support. The body should rotate in a tight arch instead of with a loose lower back.
Successfully adding more twists to yurchenkos in large part depends on the gymnast's focus. A skill this difficult is achieved by taking progressive steps. What the gymnast does before he is in the air plays a big role in the outcome of the skill. A good hurdle that moves up and forward along with a round-off that contacts the board with the center of mass in front of the feet is important.
A large percentage of skills on the vault can be performed into the pit when training to minimize stress on the gymnast's joints. This is true for new skills and skills that are already known. Layout twisting is always more effective with a straight body line, the head neutral, and the arms close to the mid-section.
