When most people think of competitive trampoline gymnastics, they picture an athlete bouncing up and down on a single, massive rectangular bed. However, the international gymnastics landscape features another highly explosive and technically demanding discipline: the Double Mini Trampoline (DMT).
Governed internationally by the Fédération Internationale de Gymnastique (FIG), DMT showcases incredible velocity, core control, and spatial awareness. It bridges the gap between traditional artistic gymnastics vaulting and Olympic-sized trampoline routines.
This comprehensive guide breaks down what a Double Mini Trampoline is, how the equipment is structured, competitive rules, and how judges score a world-class pass.
📐 The Equipment Layout and Dimensions
Unlike a standard mini-trampoline used in backyard fitness setups, a competitive Double Mini Trampoline is a precision-engineered apparatus.
The name “Double Mini” comes from its two-level bed design:
- The Run-Up: Athletes sprint down a synthetic track or runway (typically 20 meters long) to build maximum linear momentum.
- The Slanted Section (Mount): The first part of the trampoline bed is angled upward. Gymnastics athletes use this section to execute their initial “mount” skill.
- The Flat Section (Spotter/Dismount): The second part of the bed is completely flat. Here, the gymnast can perform an intermediate skill (called a spotter) or build ultimate spring energy for a massive dismount.
The frame is wrapped heavily in thick safety padding, and the landing zone is heavily cushioned with thick mats marked with target scoring zones.
🏃 How a Competitive DMT Pass Works
In a standard competition, a gymnast performs a “pass.” A complete, successful pass lasts only a few seconds but requires absolute perfection. It consists of exactly three main phases:
- The Run-Up & Mount: The gymnast sprints down the runway, leaps onto the angled first bed, and launches into the air performing their first aerial skill (flips, twists, or somersaults).
- The Spotter or Mounter:
- Spotter Pass: The gymnast lands their first skill precisely on the flat section of the trampoline bed, immediately rebounds into a second aerial skill, and flies off.
- Mounter Pass: The gymnast performs a skill off the first bed, flies clean over the flat section without touching it, and goes straight into a dismount.
- The Dismount & Landing: The gymnast performs their final, most complex aerial maneuver and must “stick” the landing inside the designated landing zone on the safety mat without taking any correction steps.
📊 Double Mini Trampoline vs. Traditional Trampoline
| Feature | Double Mini Trampoline (DMT) | Traditional Trampoline (Individual) |
| Apparatus Shape | Dual-level, two-part smaller angled bed | Flat, large single rectangular bed |
| Routine Style | Linear pass (Athlete moves forward) | Stationary (Athlete bounces in one spot) |
| Number of Skills | Exactly 2 scoring skills per pass | 10 continuous skills per routine |
| Approach | Requires a fast 20-meter sprint run-up | Starts from a stationary standing position |
📝 Rules and Scoring Criteria
DMT judging is incredibly strict because the margin for error at high speeds is virtually zero. Judges evaluate a pass based on three main metrics:
1. Difficulty (D-Score)
Every flip, twist, and rotation has a predetermined mathematical difficulty value. Double flips with multiple twists carry higher D-scores. The more complex the airborne rotation, the higher the starting score.
2. Execution (E-Score)
Gymnasts start with a perfect execution score, and judges deduct points for technical flaws, such as:
- Bent knees or unpointed toes.
- Separated legs during flips.
- Moving out of the center axis of the trampoline bed.
3. The Landing (Sticking the Pass)
The landing is paramount. If a gymnast falls forward, steps back, or touches the mat with their hands upon landing, massive point deductions are applied. To get a perfect score, an athlete must achieve a “stuck landing”—stopping completely still immediately upon impact.
Frequently Asked Questions (FAQs)
Is Double Mini Trampoline an Olympic sport?
No, currently only Individual Trampoline is an official discipline in the Summer Olympic Games. However, Double Mini Trampoline is a major highlight event at The World Games and the FIG Trampoline Gymnastics World Championships.
How many flips do athletes do on a DMT?
Top-tier international athletes regularly perform double and triple somersaults with multiple twists (such as triple-backflips with half-twists) within a single pass.
What happens if a gymnast misses the trampoline bed?
Missing the bed or failing to land feet-first on the trampoline results in an immediate score of 0.0 for that specific competitive pass due to safety protocols.
