Safety
Using a trampoline can be dangerous. Organized clubs and gyms usually have large safety end-decks with foam pads at each end, and spotters are placed alongside the trampoline to try to break the fall of any athlete who loses control and falls. In 1999, the U.S. Consumer Product Safety Commission estimated there were 100,000 hospital emergency room visits for trampoline injuries.[25]
Due to the much larger numbers involved and lower safety standards, the majority of injuries occur on privately owned home trampolines or in commercial trampoline facilities rather than organized gyms.[26]
CBC Television's Marketplace discovered that the trampoline park industry is unregulated in Canada, with different standards for padding and foam pit depth, self-inspections and repairs, and not being required to report injuries. It was also noted that there were generally too few staff to enforce rules, and that promotional advertisements often showed participants engaging in somersaults even though this was extremely dangerous without proper training. All trampoline parks rely upon liability waivers, where the signee assumes the risk of the activity including when injuries result from the establishment's own negligence or poorly maintained equipment, rather than beefing up safety standards and supervision.[27][28]
Bouncing off a trampoline can result in a fall of 3 - 4 m from the peak of a bounce to the ground or a fall into the suspension springs and frame. Some medical organizations have suggested that the devices be banned from home use.[29][30]
Authorities recommend that only one person should be allowed to jump at a time to avoid collisions and people being catapulted in an unexpected direction or higher than they expect. One of the most common sources of injury is when multiple users are bouncing on the trampoline at one time. Often, this situation leads to users bouncing into one another and thus becoming injured; many suffer broken bones as a result of landing badly after knocking into another user.[30]
Another of the most common sources of serious injury is an attempt to perform somersaults without proper training. In some cases, people land on their neck or head, which can cause paralysis or even death.[30] In an infamous incident in the 1960s, pole-vaulting champion Brian Sternberg became paralyzed from the neck down in a trampoline accident.
Danger can be reduced by burying the trampoline so the bed is closer to the surrounding surface to lessen falling distance, and padding that surrounding area. Pads over the spring and frame reduce the severity of impact injuries. Keeping the springs covered also reduces the risk of a limb falling between the gaps in the springs and the rest of the body falling off the trampoline.
Kits are available for home trampolines that provide a retaining net around the trampoline and prevent users from bouncing over the edge. The American Academy of Pediatrics states that there is no epidemiological evidence that these improve safety.[30] The nets do prevent jumpers falling off the trampoline onto the ground, but these falls are not the most common source of injury. Multiple users bouncing in a netted trampoline can still be injured. Safety net enclosures have a larger benefit for safeguarding solo trampolinists, so long as they avoid falling on their head or neck.
Having some training in a gym may be beneficial in alerting people to possible hazards and provide techniques to avoid bad falls.[31]
Family-oriented commercial areas in North America, such as shopping centres, carnivals, and so on, often include closed inflatable trampolines (CITs) as a children's attraction. These have safety nets on the sides to prevent injuries.
Socks
Trampoline socks, also known as trampolining socks,[33] are socks that are specifically designed for trampoline use.[34] These types of socks have rubber soles[35] that help feet stick to mats or other smooth surfaces.[36] They are special socks that provide better traction on trampolines.[37] In the early days, these socks were primarily used to prevent injuries to trampolinists,[38] who wore them during trampoline gymnastics.[39]
