Erecting & Folding Away A Trampoline
- Trampolines should be carried out by trained staff or under supervision of trained staff.
- Make sure that no heavy part such as the frame ends or the whole trampoline is allowed to move quickly or develop momentum.
3. During use, place the roller stands away from the
4. Never pull the trampoline frame towards you when folding it up and do not walk under it. The trampolines are extremely heavy & can tip over on top of you to cause serious injuries.
Rules of Olympic Trampolining
Both men and women compete independently in individual events in the Trampolining.
In the qualifying round competitors complete both compulsory and optional routines, while the final consists of just an optional routine.
The compulsory routine contains a prescribed set of skills, which must be performed in a set order, while the optional routines must contain 10 recognized skills. These skills are submitted on cards to the judges, but can be performed in any order. Each of the 10 skills in an optional routine should be different, i.e., skills should not be repeated in the same routine.
Routines should end with the Trampolinists in an upright position with both feet on the trampoline bed. They must remain upright for at least three seconds at the end of the routine. Points are deducted for unsteadiness.
For all skills apart from straddle jumps, the legs should be kept together with the toes pointed.
Only one attempt at each routine is allowed, unless the routine is interrupted by outside interference.
There is no time limit on routines.
Skills include twists and somersaults in a variety of positions. Each is given a degree of difficulty, the higher the difficulty the higher the score. The number of twists and somersaults in each skill dictates its difficulty rating.
A full somersault is worth 0.4 of a point, a quarter somersault is worth 0.1 and a three-quarter somersault is worth 0.3 of a point. A full twist scores 0.2 of a point and a half twist 0.1 or a point. If a move includes a somersault and a twist, the scores are added. If the somersault does not include a twist but is performed in the pike or straight position, 0.1 of a point is added for each complete somersault.
Two difficulty judges confer to give each routine a difficulty score, which is usually in the range of 11-15 points.
A board of five judges rate the execution of each routine, giving a score out of 10. They look at form, consistent height and control, deducting fractions of points for faults.
Failing to hit the trampoline with both feet at the same time costs 0.3 of a point, touching the trampoline bed with the hands draws a 0.4 of a point penalty, touching the bed with the hands and knees is worth a half a point penalty and landing on a safety platform results in a 0.8 of a point penalty.
In trampolining technical ability is not enough for a good score, style is also important.
Judges reward competitors who perform with artistry and grace.
The highest and lowest scores for each routine are discarded and the other three are totalled.
The difficulty score is then added, giving a final score for the routine.
If scores are tied, the scores are added again, this time including the two discarded scores, to determine a result.
Basic Shapes
Pike - Body position where legs are straight, together and the body is bent at the hips. For competition, minimum angle is 135° but 90° or less is considered good form.
Straddle - Like a pike, but with legs apart. For competition, minimum is shoulder width but 90° or more is considered good form.
Tuck - Body position with legs bent at the knees and hips. For competition, both angles must be 135° or less. For good form, legs must be bent 90° or less and hands must grasp the legs below the knees.
Half Twist - The performer faces one direction on a trampoline and the jumps and turns 180 degrees to face in the other direction.
Full Twist - The performer faces one direction on a trampoline and the jumps and turns 360 degrees to face in the same direction as they started.
Seat Drop - For a good seat drop, the performer should stretch to the top of the jump – pushing the hips forward slightly at the same time. On the way down, pointing the toes towards the mat will allow the performer to land sitting on the trampoline. . The correct position is with the legs together, leaning slightly backwards. One important thing to remember is the fingers should be pointing towards the toes.
Swivel Hips - Seat drop, ½ twist to seat drop. This move should go through a “standing” position in the air.
Front Drop - For a good front drop, the take off should be straight with lots of lift. When landing, the knees should be slightly bent so that the feet can be kicked down towards the trampoline to allow a straight return to feet. Pushing with the hands will also help the return to feet.
Back Drop - As the performer begins to descend towards the trampoline, the legs are piked and the performer lands in the bed with toes pointing to the ceiling. Squeezing the abdominal muscles on landing & kicking the legs allows a good return to feet.
Front Somersault - 360 degrees of rotation, forwards, starting and finishing on the feet. Front somersaults may be tucked, piked or straight. A good front somersault has three phases
- Take off – a straight take off which lifts upwards. Pushing the hips backwards creates the rotation.
- Shape – a fat, tight shape phase which speeds up the rotation.
-
Line out and landing – a strong line out to a straight shape slows the rotation again to land.
Back Somersault - 360 degrees of rotation, backwards, beginning and ending on the feet. Again, back somersaults may be tucked, piked or straight. A good back somersault has the same three phases
- Take off – a straight take-off, which lifts upwards. Pushing the hips forwards creates rotation.
- Shape – a fast, tight tucked or piked shape will speed up the rotation. If the somersault is straight, bringing the arms into the sides will also speed up the somersault.
- Line-out – a strong line-out to a straight shape again slows the rotation to land safely.
Front drop
Preparation: The take off should be strong but also straight
Execution: Lift the chest and hips and push legs backward towards the end of the bed. Knees should also be slightly bent. Land with elbows on the mat and hands flat and in front of the face
Follow Through/Recovery: Kick the feet towards the trampoline to allow a straight return to feet. Pushing with the hands also helps this.
Back Drop
Preparation: Good strong straight take off
Execution: legs are piked and the performer lands in the bed with toes pointing to the ceiling.
Follow Through/Recovery: Squeeze the abdominal muscles and kick your legs out to return to your feet.
Pike Jump
Preparation: Strong high but straight take off.
Execution: Legs are brought up to the chest and arms tap the knees. It is important that the knees are brought up to the chest and the chest is not brought down towards the knees as this creates a forward momentum and ruins the next bounce/shape.
Follow Through: Arms are brought back above the head to start the next bounce.
