As a gymnast gets better with a skill on the vault, it is a good idea to do the same skill to an elevated soft surface. The soft surface minimizes the stress on the gymnast's joints while making it more difficult to land. This encourages gymnasts to apply more power and improve their technique.
Coaches and gymnast must always communicate what they plan to do before each training attempt. In this case, a very experienced coach and his elite athlete have agreed that the sting mats will on be slid on the bar if the release timers show signs of trouble.
The gymnast performing these examples is still in the process of mastering this skill. As expected, he is not training this skill to a regular competition landing mat. Like in any other yurchenko vault, the hands contact the table with the gymnast in a tight arch and with the mid-section above the feet.
