trampolines

Trampolines are devices consisting of a taut jumping surface secured to a rigid frame by springs or elastic cords, designed for vertical bouncing. The jumping surface, or mat, is typically made of woven synthetic fibers and is supported by metal springs connected to a circular or rectangular frame. Round trampolines are common for home use, while rectangular units are often used for training and competition. Most models include a safety enclosure net surrounding the jumping area and padded covers over the springs and frame to reduce injury risk. Construction materials typically include a steel frame with a weather-resistant coating, galvanized springs, and a vinyl or canvas jumping mat with foam-padded padding.

The modern trampoline was developed in the 1930s by George Nissen and Larry Griswold. It originated in circus and gymnasium settings as a training and entertainment device and later evolved into a sport with standardized equipment and competitive routines.

Uses range from recreational play to athletic training and fitness. Trampolines are used for gymnastic practice, physical therapy, and recreation in homes, schools, and community centers. Competitive trampolining follows formal rules set by sport governing bodies, and training often emphasizes precision, aerial awareness, and safe landing techniques.

Safety is a major consideration, as trampolining carries a risk of injuries to the neck, spine, head, and limbs, particularly from falls or awkward landings. Safety guidelines emphasize adult supervision, one-at-a-time use, secured safety nets, substantial padding over the frame and springs, a clear surrounding area, and regular equipment checks. Users should ensure the device is properly installed on a level, non-slip surface and removed from overhead hazards.

Maintenance involves inspecting for rust, torn mats, stretched or missing springs, and worn padding, and replacing worn components promptly. Standards and recommendations vary by country, with many jurisdictions requiring safety enclosures, padding, and clear labeling.
