Overview

In trampoline, athletes are judged while performing acrobatics on a trampoline. Acrobatics include jumps such as a pike or a tuck, to more complex movements such as a twist.

Each National Olympic Committee (NOC) can qualify a maximum of two men and two women. Competition progresses from qualifying (two rounds) to the final. Up to 16 men and 16 women will compete in qualifying. Athletes complete both a compulsory and voluntary routine. The top eight athletes progress to the final.

Scoring

Nine judges officiate the Olympic trampoline competition: a chair of the judge’s panel, which controls the evaluation of time of flight and horizontal displacement, two difficulty judges, and six execution judges. 

There are four categories of scores: difficulty, execution, time of flight, and horizontal displacement, which is newly added for the Tokyo Games.  

Difficulty Score

For the first routine of the qualifying round, also known as the compulsory routine, only the difficulty value of four elements counts toward the difficulty score. For voluntary routines, the difficulty of all 10 elements is counted. 

Each athlete begins his or her routine with zero difficulty points and submits a competition card before the competition, listing the skills which they intend to perform. Each element performed has a specific difficulty value. By checking the difficulty values entered on the competition card (and ensuring that the same elements are performed), the judges determine the final difficulty score for a routine and display it. 

Execution Score

An athlete’s execution score starts at 10.0. During a routine, the six execution judges evaluate the athlete’s form and how well each skill is performed, such as whether the body line is kept straight, legs are together and a consistency of height. 

Deductions of up to 0.5 points are made for each mistake, such as an extra bounce, a mistake in form or a lack of control. The final execution score is determined by dropping the two highest and two lowest scores, and then adding the remaining two scores. Therefore, the maximum possible score for execution is 20.0. 

Time of Flight

A ‘time of flight’ machine, introduced in 2011, measures the total flight time of the gymnast to 1/1000th of a second. Horizontal displacement will also be determined by a machine. Both are operated by the chair of the judges panel.  

Horizontal Displacement

The horizontal displacement score has been introduced for the Tokyo Games in accordance with the latest version of the International Gymnastics Federation (FIG) Code of Points. It measures the deviation of the landing position outside the middle box on the trampoline (often marked in red). Deductions are made from the maximum score of 10.0 every time the feet or hip joint touch an outer zone, ranging from 0.1 to 0.3.  

Final Score 

The final score for each routine is the addition of the scores for difficulty, execution, time of flight, and horizontal displacement: 

Difficulty score + Execution score + Time of Flight score + Horizontal Displacement – Penalties (if any) = Final score 

Example: 

Difficulty mark (unlimited): 14.5 

Execution marks (8.4, 8.5, 8.38.3, 8.4, 8.5)16.8 

Time of flight: 16.675 

Horizontal Displacement: 8.2 

Penalties: 0.0 

Final score: 14.5 + 16.8 + 16.675 + 8.2 – 0.0 = 56.175 

Tiebreaking

If there is a tie in the final round, rankings will be determined by the following criteria until the tie is broken: 

  1. The sum of the execution scores of both routines.
  2. The sum of horizontal displacement scores of both routines.
  3. The sum of the time of flight scores of both routines.
  4. If the gymnasts remain tied, they will share the same classification. This may mean that more than eight gymnasts qualify for the final.

If there is a tie in the final round, rankings will be determined by the following criteria until the tie is broken: 

  1. The gymnast with the higher execution score in the final routine. 
  2. The gymnast with the higher horizontal displacement score in the final routine. 
  3. The gymnast with the higher time of flight score in the final routine.
