Donald Wallace (Wally) Gordon (4 February 1932 – 11 April 2016) was an American gymnast and inventor who is notable for inventing the first landing mats, incline mats, octagons and all the other foam shapes that currently fill gymnastic schools. [1]
The four heights, measured by the distance the subjects’ feet were elevated above the trampoline bed, were 18, 37, 75, and 100 cm. A 5- to 10-min rest period was provided between each jumping level." The jump heights in inches were: 7", 14.6", 29.5" and 39.4". The NASA study did not involve a rebounder or mini-trampoline.
Mats are used for safety in gymnastics, and in training new skills. They are usually a piece of foam (covered in leather) ranging from 1.5 to 28 inches thick, covered in a vinyl or plastic lining. The foam ranges in density from relatively firm to very soft. Landing mats are usually blue but can be almost any other color.
A double mini trampoline is smaller than a regulation competition trampoline. It has a sloped end and a flat bed. The gymnasts run up and jump onto the sloping end and then jump onto the flat part before dismounting onto a mat. Skills are performed during the jumps or as they dismount. A double mini-trampoline competition consists of two types ...
Tuck Jump – From a straight jump start, the knees are pulled up to the chest and the hands must at least briefly grasp the legs between the knees and ankle. Pike Jump – Again from a straight jump start, the legs are straight, held together and lifted parallel to the trampoline and the arms and body reach forwards towards the pointed toes.
Nissen remained involved in a trampoline manufacturing business making trampolines for exercise and for space ball, a game similar to volleyball but played on a trampoline surface. Nissen had always wanted to have trampolining included in the Olympic Games. This finally happened in the 2000 Summer Olympics in Sydney.
Most competitive gymnastics floors are spring floors. They contain springs and/or a rubber foam and plywood combination, which make the floor bouncy, soften the impact of landings, and enable the gymnast to gain height when tumbling. [2] [3] Floors have designated perimeters called the delimitation strip, indicating an out of bounds area. [4]
The trampoline-like life nets once used by firefighters to catch people jumping out of burning buildings were invented in 1887. The 19th-century poster for Pablo Fanque's Circus Royal refers to performance on trampoline. The device is thought to have been more like a springboard than the fabric-and-coiled-springs apparatus presently in use. [1]
