To perform Kasamatsu vaults, the gymnasts do not execute a complete round-off over the table. Instead, they should repulse the table sideways and continue twisting. Observe in this slow motion example how the gymnast leaves the table sideways. By the time he stands up vertically, he is already facing away from the table.
Maximizing the gymnast's power through the appropriate physical preparation and applying this power to build tumbling speed and quick rebounds helps to create upper level tumbling skills. Observe this demonstrator's quick round-off to handspring rebound.
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.
