question: Why does jumping on the trampoline just before someone lands make them launch way higher?
comment: It basically turns into the same effect as a see-saw. You when you land, it causes the restoration the trampoline to tighten to make up for the giant spot you just stretched. When it tightens, it makes other pits, such as ones people are standing in, to become smaller, thus pushing them upwards. Same thing as the videos with people jumping on to big air bags and launching people off the other side
passages: In senior level competitions, a "Time of Flight" (ToF) score was added to the overall score from 2010. This benefits athletes who can maintain greater height during their routines. "Time of Flight" is the time spent in the air from the moment the athlete leaves the mat until the time they make contact again and is measured with electronic timing equipment. The score given is the sum the time in seconds of all completed jumps.
   Section::::Basic landing positions.
  
  Competitive trampolining routines consist of combinations of 10 contacts with the trampoline bed combining varying rotations, twists and shapes with take-off and landing in one of four positions:
  
  BULLET::::- Feet
  
  BULLET::::- Seat
  
  BULLET::::- Front
  
  BULLET::::- Back
   BULLET::::- Human Sticky Jump: Teams are dressed in Velcro suits. One member from each team must then run down a ramp towards a Velcro wall with an outline pattern pictured, jump on a small trampoline and try to land on the wall to match up the wall's pattern as closely as possible. Judge Masa decides which player best filled the pattern. The team who scores 2 out of 3 jumps first wins.
   In 2017, the method of determining the horizontal displacement from the centre was changed, new markings were added to the bed and zones set up with deductions based on the distance from the centre of the trampoline bed. The score is determined by a deduction which is the sum of all the landing zone deductions subtracted from 10. The displacement is measured electronically where the equipment is available, or else by two judges observing the landing zones.
   BULLET::::- Throat Erosion - Replacing Mother Tongue and Brain Matter in certain episodes, competitors must use an industrial trampoline to jump and grab a lever releasing a climbing wall.
  
  BULLET::::- Faceplant - Competitors stand on a narrow platform, hands braced against panels on either side, as they are tilted forward to a 45° angle. They must then jump to a rope (sometimes a chain) and swing to the next obstacle.
   BULLET::::- Faceplant - Competitors stand on a narrow platform, hands braced against panels on either side, as they are tilted forward to a 45° angle. They must then jump to a chain and swing to the next obstacle. The first Point Thruster is located higher up the chain. Unlike previous seasons, the chain is positioned towards the side a bit. This is the first of five checkpoints in the Semifinals.
  
  BULLET::::- Hyper Jump - Competitors must jump across 2 semi-stationary hanging platforms that start moving once the competitor lands on them. A Point Thruster is located between the platforms.
   BULLET::::- Drop Zone - Competitors must scale an angled-trampoline to a blue ramp. A Point Thruster is (sometimes) located near the base of the ramp. This is the second of five checkpoints for the Semifinals.
  
  BULLET::::- Pivot Point - Competitors must jump from the ramp to a hexagonal-platform near the base of Digestive Track. The drop is said to be 10 ft down. This is the third of five checkpoints for the Semifinals.
  
  BULLET::::- Digestive Track - Jumping from the last spinning platform into a tube, competitors must climb the tube before it sinks and jump to the next obstacle.

   "The Amazing Race" courses were planned so that the final three teams would all reach the finish line. However, Joe & Bill (“Team Guido”) were so far behind that they could not catch up and did not finish the race. When they were still completing Leg 12 (which aired alongside Leg 13 in the final episode), Team Guido was required to have villagers bounce one teammate upwards using an Alaskan tapestry. According to the DVD commentary, the tapestry broke under the weight the day before, so a trampoline had to be used instead.

   BULLET::::- Stomach Drop or Front Landing – Landing horizontally on the bed, face down, with the arms bent to form a diamond shape with the hands overlapping slightly in front of the face. The legs should be bent slightly at the knee keeping the feet off the trampoline bed. But otherwise held in tension for a good landing.
   Gymnastics at the 2010 Summer Youth Olympics – Men's trampoline
  
  Men's trampoline competition at the 2010 Summer Youth Olympics was held on 20 August at the Bishan Sports Hall.
   BULLET::::- Trampoline – Competitors must bounce off of trampolines onto stacks of foam blocks. This competition has three stages, and all competitors who complete the first stage are held until all competitors attempt the stage. Afterwards, all successful competitors attempt the second stage in the same manner.
   There are a number of other sports that use trampolines to help develop and hone acrobatic skills in training before they are used in the actual sporting venue. Examples can be found in diving, gymnastics, and freestyle skiing. One main advantage of trampolining as a training tool for other acrobatic sports is that it allows repetitive drill practice for acrobatic experience every two seconds or less, compared with many minutes with sports that involve hills, ramps or high platforms. In some situations it can also be safer compared to landings on the ground.
  
  Section::::Types of trampolines.
   BULLET::::- Balks will receive a 2-point deduction from each judge for the first balk. Another 2-point deduction for the second balk and be considered a failed dive on the third balk. A balk is considered an interruption in movement after the diver does his press immediately before the dive. For armstand dives it is the point when both feet leave the platform (use FINA definitions).
  
  BULLET::::- Running take-offs on forward dive groups (including twists) are allowed, given there is enough space for the approach.

   In co-operation with the University of Bremen and the German Aerospace Center (DLR), the machtWissen.de Corporation from Bremen, Germany developed the weightlessness demonstrator "Gravity Jumper" based on a trampoline. Due to the acceleration during the jump, an acceleration force takes effect in addition to the usual gravitational force. Both forces add up and the person on the trampoline seems to become heavier. As soon as the jumper leaves the trampoline, he is under a free fall condition, which means that the jumper seems weightless and does not feel the acceleration due to gravity.

   BULLET::::- In Objective-C, a trampoline is an object returned by a method that captures and reifies all messages sent to it and then "bounces" those messages on to another object, for example in higher order messaging.
   After losing the game and suffering Troy's insults, Jeff kicks the basketball over a hedge, where the pair then find a seemingly magical secret garden that includes a trampoline. They meet Joshua (Matt Walsh), a mild-mannered Greendale gardener who keeps the area private because trampolines have been banned from the school. They find unexpected bliss in jumping on the trampoline, and Joshua allows them to continue to visit as long as they keep it a secret and never "double bounce" on the trampoline.
   Section::::In the Quake series.
   During World War II, the United States Navy Flight School developed the use of the trampoline in its training of pilots and navigators, giving them concentrated practice in spatial orientation that had not been possible before. After the war, the development of the space flight programme again brought the trampoline into use to help train both American and Soviet astronauts, giving them experience of variable body positions in flight.
  
  Section::::History.:Competitive sports.
   Early in their development Nissen anticipated trampolines being used in a number of recreational areas, including those involving more than one participant on the same trampoline. One such game was Spaceballa game of two teams of two on a single trampoline with specially constructed end "walls" and a middle "wall" through which a ball could be propelled to hit a target on the other side's end wall.

   The last 30 seconds of the Teleop Period is called the End Game. During this time, robots can earn additional points by performing tasks in their Platform Zone. If a robot is fully supported by the Scale, fully outside the opponent's Platform Zone and has its bumpers at least 1 foot above the Platform when time runs out, the robot earns a Climb and 30 points. If a robot has met all of the criteria above but does not have its bumpers at least 1 foot above the Platform when time runs out, the robot earns a Park and 5 points. If the Levitate Power Up has been activated and no more than 2 robots have Climbed, a Climb is credited to a random robot who has not Parked or Climbed. If all robots have at least Parked, one random robot who has not Climbed will be credited with a Climb.
