The trampoline events consist of two phases:
Qualifications – The athletes perform two routines, a voluntary routine with 10 elements that includes special requirements, and a second voluntary routine with 10 different skills without any limits.
Finals – The top eight athletes from the qualification round perform only one voluntary routine, with 10 different elements without a limit. The score from the qualification round determines the start order for the finals, but the score does not carry forward.
The required elements are (1) a skill that lands on the stomach or back; (2) a skill that takes off from the stomach or back (in combination with requirement #1); (3) a double somersault (forward or backward) with or without a twist; (4) a double somersault (forward or backward) with a minimum 360-degree twist; (5) a somersault (single or multiple, forward or backward) with a minimum 540-degree twist; in addition, all skills must have a minimum 270-degree somersault rotation. Each trampoline routine consists of 10 elements. Athletes are obliged to submit a competition card 48 hours prior to the commencement of the event in which they state the exercises they intend to present. During the routines, every element the athlete performs has a specific difficulty value.
The chair of the judges panel, with the cooperation of the assistant chair, determines the maximum score for each routine, depending on the number of elements in the routine. For a 10-element routine, the highest possible score is 10 points, while for a seven-element routine the highest score is seven points. Two difficulty judges calculate the scores for each element and add the scores together, the total of which is the final difficulty mark.
Five execution judges evaluate the quality of the execution of the routine. They take note of technical mistakes such as the lack of the right positioning of the body, loss of height and loss of control during the exercises and a shaky final landing. They then make deductions from the maximum score, as determined by the chair of the judges panel. The highest and lowest marks of the five execution judges are deleted and the three remaining marks are added together to give the execution score for the routine. The total score for each routine is the addition of the mark for difficulty and the final mark for execution. The competitor with the highest total score in the final wins.
