Resilient sheet or web (often of nylon) supported by springs in a metal frame and used as a springboard and landing area in tumbling. Trampolining is an individual sport of acrobatic movements performed after rebounding into the air from the trampoline. As a competitive sport, it was included in the Pan-American Games for the first time in 1955, and a world championship was established in 1964; competitors are scored on difficulty, execution, and form.
