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 regular competition trampoline. The apparatus has both an angled section and a flat section. Unlike individual trampoline, where scoring is predominantly determined by Execution, Time of Flight and Difficulty, the Difficulty in DMT plays a more prominent role in the final score.
A DMT routine or pass 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.
Here's an overview of how the judging process typically works:
Difficulty (D-Score): The difficulty score, often referred to as the D-Score, is based on the complexity of the skills and combinations performed during the routine. Each skill has an assigned difficulty value, and the gymnast's routine is evaluated based on the total difficulty of their skills. Judges assess the complexity of flips, twists, and connections between skills to determine the D-Score.
Execution (E-Score): The execution score, or E-Score, reflects how well the gymnast performs each skill. Judges deduct points for errors in technique, form, landing, and other imperfections. Deductions are made for mistakes such as bent knees, crossed legs, loss of control, and landing outside the designated area. A panel of judges assigns execution deductions based on their observation of the routine.
Amplitude: Amplitude refers to the height or air time achieved during skills. Gymnasts are rewarded for performing skills with greater height, as it demonstrates control and power. Higher amplitude also allows gymnasts more time to complete complex maneuvers. Judges take into account the height and control displayed by the gymnast during their routine.
Presentation: Presentation includes aspects such as the gymnast's posture, expression, rhythm, and overall performance quality. A well-presented routine demonstrates confidence, style, and engagement with the audience and judges. Presentation is subjective and adds to the overall impression of the routine.
Deductions: In addition to execution deductions for specific errors, there might be general deductions applied for issues like incomplete or off-centered landings, falls, or interruptions in the routine.
Total Score: The final score is calculated by adding the D-Score and the E-Score and then subtracting any applicable deductions. The highest and lowest judges' scores are often dropped, and the remaining scores are averaged to determine the final score for the routine.
The gymnast with the highest total score wins the competition. In larger competitions, there might be multiple rounds, and the gymnasts with the highest combined scores from all rounds are typically the winners.
The DMT is administered by FIG, the International Gymnastics Federation, and is included as a trampoline gymnastics event. Although not yet an Olympic sport, elite DMT athletes can compete at the international level and qualify for various FIG-sponsored events and world competitions.
