A springboard is a platform set upon one or usually multiple springs used in artistic gymnastics to propel a gymnast who jumps upon it further than if they had otherwise jumped off a fixed platform.
[1] The springboard is a vital part of the vault event and is commonly used in some routines of other events, such as the balance beam, or uneven bars, to start the event by springing onto the apparatus.
Named 'Reuther boards' after their inventor, Richard Reuther, they allowed gymnasts to gain more speed and height when vaulting.
The 1991 World Championships used springboards, while the 1992 Summer Olympics used Reuther boards.
Gymnasts may choose between the hard and soft boards for vault, but they may only choose to use the soft board on other events.
