Double mini trampoline

Double mini trampoline, sometimes referred to as double mini or DMT, is a gymnastics discipline within trampolining. Participants perform acrobatic skills on an apparatus smaller than a regulation competition trampoline. The apparatus has both an angled part and a flat part.[1]

A DMT routine consist of two phases. The first phase is called a "mount"; during this phase the athlete jumps onto the angled part and flips off of it onto the flat part. The first phase can also be performed by jumping, without flips or twist, onto the flat part and then commencing the first flip or twist. In this case the first phase is called a "spotter". The second phase starts on the flat part and is called a "dismount"; the athlete lands the first flipping sequences from phase one and immediately launches into a second series of flips and twists before landing on a mat.[1]

The athletes are judged on execution and difficulty.[2] There are both individual and team competitions in the sport.[1]

DMT is governed by the FIG, the International Federation of Gymnastics, and is included as an event within trampoline gymnastics. Although not currently an Olympic event, elite DMT athletes compete at international level and can compete in various events organised by the FIG as well as at the World Games.

History

DMT can be sourced back to 1970 when it's inventors Robert F Bollinger and George Nissen combined two Mini trampolines with a small table and mat to cover in between. Later Robert F Bollinger combined the two Mini trampolines to create one 430cm long Double Mini Trampoline and also designed the rules for competition and terms such as the mounter and spotter passes.[3] [4] Robert F Bollinger was part of George Nissen's trampoline act and just as Nissen can be seen as the birth father of Trampoline Robert F Bollinger can be seen as the birth father of Double Mini Trampoline.[5]
The first record of a Double mini competitions comes from the 1th Trampoline Gymnastics World Age Group Competitions in 1973 held in London, England.[6] Athletes competing had little experience in the new apparatus and Robert F Bollinger jumped in and provided personal training on the friday afternoon for the athletes wishing to compete the following day.[6] Double mini was first introduced in the Trampoline World Championships only 6 years after its inventions in the 1976, 9th Trampoline World Championships in Tulsa.[3][7]

Skills

Some common skills performed at international level competitions are:[8] A Comprehensive list of skills can be found in FIG Code of Point Difficulty.

Full in full out

alternatively double-twisting double back

A somersault commonly used as a dismount in which the athlete takes off traveling backwards and does a double somersault with a double twist, full twist in the first somersault and full twist in the second somersault. This skill can be performed ether tucked, piked or straight.[2]

Triple back somersault

A somersault commonly used as a dismount in which the athlete takes off traveling backwards and does a triple somersault. This skill can be performed either tucked, piked or, uncommonly, straight.[2]

Miller

alternatively Full in Double-full out or Triple-twisting Double back

A somersault used as a dismount in which the athlete takes off traveling backwards and does a double somersault with a triple twist. This skill is named after world champion Wayne Miller (USA).[1] This skill can be performed ether tucked, piked or straight.[2]

Full in half out

alternatively Full in Barani out

A somersault commonly used as a mount in which the athlete takes off traveling forwards and does a double somersault with a one and a half twist, full twist in the first somersault and half twist in the second somersault. This skill can be performed ether tucked, piked or straight.[2]

Fliffis

alternatively Half out

A somersault commonly used as a mount in which the athlete takes off traveling forwards and does a double somersault with a half twist, no twist in the first somersault and half twist in the second somersault. This skill can be performed ether tucked, piked or straight.[2]

Triffis

alternatively Half out Triffis

A somersault commonly used as a mount in which the athlete takes off traveling forwards and does a triple somersault with a half twist, no twist in the first somersault, one twist in the second somersault and a half twist in the third somersault. This skill can be performed either tucked or piked.[2]

FIG Code of Point Difficulty

The difficulty in double mini is based upon a bonus system, where the number of rotation and twists are multiplied and then the position is added. [9] The positions are tuck, pike and straight which are represented by "O" for Tuck, "<" for Pike and "/" for Straight[2]

Bellow is a table showing the skill followed by its FIG numeric system its position and its corresponding difficulty (Diff).
