trampolin

Trampolin, also known as a trampoline, is a device consisting of a taut fabric bed stretched over a steel frame by numerous springs or elastic cords. The bed rebounds when a person jumps on it, enabling aerial movement and soft landings. Trampolins are used for recreational jumping, athletic training, gymnastics, and performance contexts. Many models include a safety enclosure to reduce the risk of falls.

Origin and development: The modern trampolin was developed in the 1930s by American inventors George Nissen and Larry Griswold. They built practical models by combining a strong fabric bed with a network of springs to produce high rebound. Trampolin use evolved into a formal sport under the International Gymnastics Federation (FIG), with world championships dating from the 1960s and Olympic competition beginning in 2000.

Construction and varieties: Backyard trampolins typically range from about 2.4 to 4.6 meters in diameter, featuring a metal frame, fabric bed, and springs or elastic cords. They commonly include foam padding to cover the springs and an enclosure net. In sport, regulation trampolins have standardized sizes, padding, and spring tension. Other forms include mini trampolins or rebounders for fitness and therapy, and springless designs that use elastic bands or webbing.

Safety and health: Trampolin activities carry a risk of injury, especially for unsupervised use or during advanced skills. Reported injuries include sprains, fractures, and head or neck injuries. Safety guidance recommends only one jumper at a time on the main bed, proper supervision, protective padding, a clear landing area, and routine equipment checks. Users with certain medical conditions should consult a professional before use.
