springboard

A springboard is a flexible board mounted on a frame that stores energy when pressed and releases it to propel a person into the air. It is most commonly associated with diving, where the upward thrust from the board aids takeoff, but it also appears in training settings and in some athletic drills.

Construction and operation: A typical springboard consists of a reinforced top surface connected to a base by a spring system or hinge mechanism. The board flexes under the diver’s weight and then rebounds, increasing takeoff velocity. Boards are designed to bend in a controlled manner, and heights around 1 meter and 3 meters above the water are common in competitive diving venues. Safety features such as non-slip surfaces and proper maintenance are important.

Applications in diving: The springboard serves as the primary platform for springboard diving events, including individual and synchronized competition. Divers perform acrobatics such as somersaults and twists, timed to the rebound of the board. In training facilities, springboards are used to develop balance, timing, and propulsion before advancing to higher dives or platform diving.

Other uses and terminology: The term springboard is also used metaphorically to denote a starting point or catalyst for progress, advancement, or success. In some contexts, sprung or flexible boards are employed in gymnastics training or rehabilitation settings, but the standard sports springboard refers to the diving apparatus.

History: Early diving boards were rigid planks. The development of spring-loaded or flexibly supported boards in the 20th century allowed divers greater control over takeoff and trajectory, contributing to changes in technique and competition standards.
