Where it comes to tactics in trampolining it mainly revolves around the routine. The routine in trampoline is one of the most important aspects in the scoring section of trampolining. In trampolining the more difficult skills you do in your routine the more points you will get at the end.

If you do a more simple routine such as this one:

1. Full Twist (0.2), 2. Straddle Jump (0.0), 3. Seat Drop (0.0), 4. Half Twist to Seat (0.1), 5. Half Twist to Feet (0.1), 6. Pike Jump (0.0), 7. Back Drop (0.1), 8. Half Twist to Feet (0.2), 9. Pike Jump (0.0), 10. Front Somersault Tucked (0.5). Total 1.2

Then you are only going to get little marks for difficulty where as if you do a much harder routine such as the one below you will get a greater amount of points for difficulty.

1. Back Somersault Straight (0.6), 2. Straddle Jump (0.0), 3. Back Somersault Tucked to Seat (0.5), 4. Half Twist to Feet (0.1), 5. Tuck Jump (0.0), 6. Barani Piked (0.6), 7.Back Somersault Tucked (0.5), 8. Crash Dive Straight (0.3), 9. Half Twist to Feet (0.2), 10. Front Somersault Piked (0.6) Total 3.4

The second routine is much harder to pull off than the first one as the skills and moves are harder to perform making it a big risk if deciding to do so but if it is pulled off then it will tariff as you shall get a greater overall score.

Rules and Regulations

Men and women participants take part on their own in individual events in trampolining competitions.
In the first qualifying round, participants complete both required and optional routines, while the final involves of just an optional routine.
The required routine involves of a prearranged set of skills, which must then be done in a set order, while the optional routines must contain 10 acknowledged skills.
These skills are then submitted on cards to the judges, but can be completed in any order. Each of the 10 skills in an optional routine must be different.
The trampolinists should end their routine in a standing position with both feet on the trampoline. They must remain vertical for at least three seconds, before ending their routine, with points deducted for instability.
For all skills apart from straddle jumps, the legs should be kept together with the toes pointed.
Trampolinists are only permitted to try their routine once, unless the routine is interrupted by outside interference. They do not have a time limit to finish their routine.

Skills include twists and somersaults in a variety of positions. Each skill is given a mark of difficulty, the greater the difficulty, the greater the score. The number of twists and somersaults in each skill determines its difficulty rating.
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 discuss to award each routine a difficulty score, which is typically in the range of 11-15 points.
A panel of five judges rate the performance of each routine, giving the competitor a score out of 10.

The judges look at form, consistent height and control, deducting fractions of points for errors.
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 also results in a penalty.
Like the other gymnastics disciplines, 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 thrown out 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 thrown out scores, to conclude a result.

First we started warming up so that we were nice and loose and ready to do the drills. For the warm up we just went for a jog just so all the muscle were loose. We done this for about 5 Minutes before moving onto the main activity and skill based exercise.

In the main activity we focused on one main skill, basic backdrop.

The first part of basic back drop is to position yourself in the middle of the trampoline, the back landing starts in an upright position with chest & hips pushed slightly forward as you jump upwards with arms up and fingers still straight above your toes. Extending your arms and legs as much as possible the initial hip displacement causes a small amount of backward somersault rotation, enough to allow you to land on your back. The arms-extended position must be maintained throughout; just before landing the legs are raised in an action similar to piking in preparation for the correct landing position.This is done because it allows you to avoid landing in a way in which you could land head first when hitting the trampoline bed, which will also help prevent any injuries.

In the main activity we focused on one main skill, basic front drop.

The first part of basic front drop is to position yourself in the middle of the trampoline, the front landing starts in an standing position with hips pushed slightly back as you jump upwards with arms up and fingers still directly above your toes. Extending your arms and legs as much as possible the initial hip displacement causes a minor amount of forward somersault rotation. This is because you can end up falling on your front instead by over rotating. With your hands & knees move above you keep your eyes focussed towards an end wall rather than down towards the trampoline. This is done because it allows you to avoid landing in a ‘diving’ or ‘worm’ action when hitting the trampoline bed, which also prevents any injuries.

The move is performed accurately when your hips are landing approximately in the same position your feet were at take-off.

In the main activity we focused on one main skill, basic seat drop.

The first part of basic seat drop is to position yourself in the middle of the trampoline, The most important parts of this move are to keep straight legs, do not lift them up and to jump upwards first, it is inviting to ‘drop backwards’ or just lift your legs up but this isn’t what you should do. Instead you need to make yourself reach a high level and tilt your pelvis upwards slightly as you leave the trampoline; this causes a very small amount of somersault rotation. As you come back towards the trampoline you start to prepare for landing by bringing your arms down to a position ready to be placed just behind your seat and extend your feet forwards. You should land with your back close to upright and hands tucked in just behind your seat with your fingers facing the same way as your toes. This is done because it it allows you to keep your momentum when going down and allows you to be unharmed when doing the skill. It is also done because it prevent your feet from hitting the trampoline bed before they should doing which helps perfect the the move.

In the main activity we focused on one main skill, basic twists.

The first part of basic twists is to position yourself in the middle of the trampoline, the technique needs you to start the jump as much like a straight jump as possible and, as you get close to the point of last contact you twist your arms and shoulders upwards into the direction of twist, this is like coiling a spring. As you leave the trampoline the resistance previously keeping your feet in place no longer occurs, this allows the spring to uncoil and your feet now join in the twist; continuing to ‘reach round’ the twist with your arms and shoulders helps complete further twist which should now be lean-free. This is because it allows you to go further allowing you to complete the full twist meaning you can gain more more points for the skill.

In the main activity we focused on one main skill, basic bouncing.

The first part of basic bouncing is to position yourself in the middle of the trampoline, when bouncing make sure your arms are as straight as possible swinging from the side of your legs in front of you to high above your head and then back round the side to the side of your legs as you approach the trampoline again. It is important that you point your toes at all times apart from when landing on your feet. To achieve the most efficient bounce you should land with your feet ‘flat’ onto the bed and then keep them that way until the bed starts rising again. As the rise starts to accelerate press your toes deeper into the bed to drive yourself higher and then keep them pointed until just before you land again. This is because if you don’t land in the you are more likely to either go off balance with a possibility of falling off the trampoline and hurting your self and because you cant get a proper and high enough bounce.

Rules
1. The Service – Service shall start with the ball lying freely on the open palm of the server’s motionless hand. The server shall then throw the ball vertically upwards, so that it rises at least 16cm after leaving the palm hand and then drops without touching anything before being hit. As the ball is dropping the server shall hit it so that it touches first their court and then, after going over the net, touches the receiver’s court. From the start of service until it is hit, the ball shall be above the level of the playing surface and behind the server’s end line, and it shall not be hidden from the receiver by the server or by anything they wear or carry. As soon as the ball has been projected, the server’s free arm and hand shall be removed from the space between the ball and the net. The space between the ball and the net is defined by the ball, the net and its indefinite upward extension. It is the responsibility of the player to serve so that the official or the assistant official can be happy that they comply with the requirements of the Laws, and either may decide that a service is incorrect. If either the official or the assistant official is not sure about the legality of a service he or she may, on the first occasion in a match, interrupt play and warn the server; but any subsequent service by that player which is not clearly legal shall be considered incorrect. Exceptionally, the official may relax the requirements for a correct service where he or she is satisfied that compliance is prevented by physical disability.

2. The Return – The ball, having been served or returned, shall be hit so that it goes over or net and touches the opponent’s court, either directly or after touching the net.

3. The Order of Play – The server shall first make a service, the receiver shall then make a return and there after server and receiver interchangeably shall each make a return.

4. A Let – The rally shall be a let if in service the ball, in passing over or around the net assembly, touches it, provided the service is otherwise correct or the ball is obstructed by the receiver; if the service is delivered when the receiving player is not ready, provided that the receiver doesn’t attempt to hit the ball; if failure to make a service or a return or otherwise to comply with the Laws is due to a disturbance outside the control of the player; if play is interrupted by the official or assistant official; if the receiver is in wheelchair owing to a physical disability and in service the ball, provided that the service is otherwise correct, after touching the receiver’s court returns in the direction of the net; comes to rest on the receiver’s court; in singles leaves the receiver’s court after touching it by either of its side-lines. Play may be interrupted to correct an error in the order of serving, receiving or ends; to warn or penalise a player or adviser because the conditions of play are disturbed in a way which could affect the outcome of the rally.

5. Point System – Unless the rally is a let, a player shall score a point if an opponent fails to make a correct service; if an opponent fails to make a correct return; if, after he or she has made a service or a return, the ball touches anything other than the net assembly before being hit by an opponent; if the ball passes over their court or beyond their end line without touching their court, after being hit by an opponent; if an opponent obstructs the ball; if an opponent deliberately hit the ball twice in succession; if an opponent hit the ball with a side of the racket blade whose surface does not comply with the requirements: if an opponent, or anything an opponent wears or carries, moves the playing surface; if an opponent, or anything an opponent wears or carries, touches the net assembly; if an opponent’s free hand touches the playing surface.

6. A Game – A game shall be won by the player first scoring 11 points unless both players score 10 points, when the game shall be won by the first player subsequently gaining a lead of 2 points.

7. A Match – A match shall consist of the best of any odd number of games.

8. The Expedite System – The expedite system shall come into operation after 10 minutes’ play in a game or at any time requested by both players. The expedite system shall not be introduced in a game if at least 18 points have been scored. If the ball is in play when the time limit is reached and the expedite system is due to come into operation, play shall be interrupted by the umpire and shall resume with service by the player who served in the rally that was interrupted; If the ball is not in play when the expedite system comes into operation, play shall resume with service by the player who received in the immediately preceding rally. Thereafter, each player shall serve for 1 point in turn until the end of the game, and if the receiving player or pair makes 13 correct returns in a rally the receiver shall score a point. Introduction of the expedite system shall not alter the order of serving and receiving in the match. Once introduced, the expedite system shall remain in operation until the end of the match.

Regulations
1. The Table – The upper surface of the table, known as the playing surface, shall be rectangular, 2.74m long and 1.525m wide, and shall lie in a horizontal plane 76cm above the floor. The playing surface shall not include the vertical sides of the table top. The playing surface may be of any material and shall yield a uniform bounce of about 23cm when a standard ball is dropped on to it from a height of 30cm.

The playing surface shall be divided into 2 equal courts by a vertical net running parallel with the end lines, and shall be continuous over the whole area of each court.

2. The Net Assembly – The net assembly shall consist of the net, its suspension and the supporting posts, including the clamps attaching them to the table. The net shall be suspended by a cord attached at each end to an upright post 15.25cm high, the outside limits of the post being 15.25cm outside the side line. The top of the net, along its whole length, shall be 15.25cm above the playing surface. The bottom of the net, along its whole length, shall be as close as possible to the playing surface and the ends of the net shall be as close as possible to the supporting posts.
3. The Ball – The ball shall be spherical, with a diameter of 40mm. The ball shall weigh 2.7g. The ball shall be made of celluloid or similar plastics material and shall be white or orange, and matt.

4. The Racket – The racket may be of any size, shape or weight but the blade shall be flat and rigid. At least 85% of the blade by thickness shall be of natural wood; an adhesive layer within the blade may be reinforced with fibrous material such as carbon fibre, glass fibre or compressed paper, but shall not be thicker than 7.5% of the total thickness or 0.35mm, whichever is the smaller. A side of the blade used for hitting the ball shall be covered with either ordinary pimpled rubber, with pimples outwards having a total thickness including adhesive of not more than 2.0mm, or sandwich rubber, with pimples inwards or outwards, having a total thickness including adhesive of not more than 4.0mm. Ordinary pimpled rubber is a single layer of non-cellular rubber, natural or synthetic, with pimples evenly distributed over its surface at a density of not less than 10 per cm2 and not more than 30 per cm2. Sandwich rubber is a single layer of cellular rubber covered with a single outer layer of ordinary pimpled rubber, the thickness of the pimpled rubber not being more than 2.0mm. The covering material shall extend up to but not beyond the limits of the blade, except that the part nearest the handle and gripped by the fingers may be left uncovered or covered with any material. The blade, any layer within the blade and any layer of covering material or adhesive on a side used for hitting the ball shall be continuous and of even thickness. The surface of the covering material on a side of the blade, or of a side of the blade if it is left uncovered, shall be matt, bright red on one side and black on the other. The racket covering shall be used without any physical, chemical or other treatment. Slight deviations from continuity of surface or uniformity of colour due to accidental damage or wear may be allowed provided that they do not significantly change the characteristics of the surface. Before the start of a match and whenever he or she changes their racket during a match a player shall show their opponent and the official the racket he or she is about to use and shall allow them to examine it.

First we started warming up so that we were nice and loose and ready to do the drills. For the warm up we just started rallying with each other using any type of shot just getting used to the ball. We done this for about 5 – 10 Minutes before moving onto the main activity and skill based exercise.

In the main activity we focused on one skill, the topspin shot.
The first part of the Topspin Shot is to position yourself, keep your knees bent shoulder width apart, with one of your feet slightly behind the other depending on what hand you are and make sure your body is slightly square on to the table and your opponent. This is so that you are ready for the ball when it comes towards.

When the ball comes towards you, transfer you weight on to your back foot, rotate your body and open the bat up ready for the ball. Then when the ball and bat make contact put your weight on to your front, make sure that the contact is at a high point of the ball with a big follow through. This is best because it allows you to get enough and as much spin on the ball in which you would want while still allowing you to still provide enough power to test your opponent.

After getting used to the shot we added in some rules in which made us have to get the ball on to a mat on the table. We first started rallying at a reasonable speed aiming for the mat on the table. We did this for a while so that the accuracy of the shot would then improve. After a while it was then turned into a competition in which allowed us to try harder to get it in the section allowing our technique to improve.

In the main activity we focused on one skill, the backspin shot.
The first part of the Backspin Shot is to position yourself, keep your knees bent shoulder width apart, with one of your feet slightly behind the other dependant on what hand you are and make sure your body is slightly square on to the table and your opponent.

When the ball comes towards you, transfer you weight on to your back foot, rotate your body and open the bat up ready for the ball. Then when the ball and bat make contact put your weight on to your front, make sure that the contact is at low point of the ball with a short follow through.This is best because it allows you to get enough and as much spin on the ball in which you would want while still allowing you to still provide enough power to test your opponent.

After getting used to the shot we added in some rules in which made us have to get the ball in to certain section of the table. We first started rallying at a reasonable speed aiming for the section on the table. We did this for a while so that the accuracy of the shot would then improve. After a while it was then turned into a competition in which allowed us to try harder to get it in the section allowing our technique to improve.

Backspin Technique:
1. Stand outside left side line with left foot slightly in front
2. Upper body parallel to left side line
3. Serve grip, hands close together
4. Throw ball up
5. Rotate upper body to right
6. Racket opened in back swing position
7. Transfer weight to back foot
8. Transfer weight to front foot
9. Rotate upper body to left, bringing racket to ball
10. Low contact point on ball
11. Low position of ball to table
12. Forearm and wrist snap at contact to produce maximum racket acceleration
13. Short follow-through
14. Upward motion of wrist
