National Governing Rules & Regulations

Learning Outcome: Understand and apply the rules, regulations and scoring systems in the identified sports.

The individual sport in which I have chosen to report on is Table Tennis. I have chosen this because I have a particular interest in the sport and have observed my Mum and Uncle play the sport at a competitive level for many years.

   Table tennis consists of either an individual or a doubles team competing to win a point in which they have to get eleven by at least two clear points to win the game. There are many ways in which you can win a point these are;

  • If your partner fails to return the shot although the ball must have hit the table which includes the white boundary lines or even the edge of the table.
  • If your opponent fails to serve legally or misses the ball when they go to serve.
  • If your opponent hits the ball into the net and it come back onto their side of the table.
  • If the opponent hits the ball so after the first bounce it goes wide of the table and fails to take a second bounce on your side.
  • If your opponent hits the ball before it has bounced on theirs side of the table; no volleying is allowed.
  • If your opponent fails to hit the ball after the first bounce.
  • If your opponent moves or touches the net or table during play.

   There are certain requirements that are needed in order to be able to complete a game of table tennis these include, 2 or 4 players (singles or doubles), an official sized ball, official sized table, the correct type of net, an appropriate paddle and the standard clothing and footwear.

The Ball

   There were recently world wide changes for the size of the ball. It used to have a diameter of 38mm however; they increased this to 40mm. It should also weigh 2.7g.

  The Table 

   The table should be in a rectangular shape with the dimensions of 9ft long by 5ft wide. The table should be parallel to ground and exactly 2ft 6” above the ground. It should be a uniform, matte colour with a 2cm white line around the outer edge of the table. In a game of doubles there should be a 3mm white line up the centre of the table running parallel to the side lines. The permanent marking of this line does not invalidate the table for a singles match.

Net Assembly

   There are also certain requirements for net assembly these consist of, the net, the suspension and supporting posts including the clamps attaching them to the table. Each post should be 6inches high, so that the net is the same height and is parallel to the table; it is attached to the pole by a cord. The net should be as close to the table and supporting posts as possible.

The Racket

   The racket can be of any size or shape but the blade must be flat and firm. The thickness of the blade should be made up of at least 85% natural wood. An extra layer made of carbon fibre, glass fibre, or compressed paper may be used to reinforce the blade, however can only have a thickness of up to 7.5% of the total thickness of the blade. The side of the blade used for striking the ball has to be covered with a rubber, either, pimpled with pimples outwards or sandwich with pimples facing inwards or outwards. If using the pimpled rubber the total thickness, including adhesive, must not be more than 2mm, however if using the sandwich rubber the total thickness must not be more than 4mm.  

Rules of the Game

   As with any game there are certain rules which must be followed throughout the game. In table tennis there are many rules which relate to several parts of the game, the service being the first.

Service   

   The service of the ball also has many regulations, one of these is that the ball must rest freely on the players’ open palm, the hand must be motionless. Before serving the ball should be above the playing service and behind the server’s end line. When starting the serve the ball must be thrown upwards at least 16cm without moving your hand in such a way that it will cause the ball to spin. Also it is the responsibility of the player to serve that so the umpire or assistant can clearly see whether they are complying with the rules of service. If a player is seen to be serving illegally, for example, flicking the hand when throwing the ball to create spin, then for the first instance they are given a let and warned. However, if they continue to abuse the service rules then the opponent may receive a point without a warning. When striking the ball it must first bounce on your side of the table and then your opponents for the service to be legal.

The Return & Order of Play   

   When returning the ball it should be struck so that it passes over or touches the net and then touches the opponent’s court. The order of this play starts with the server making the first service with the receiver making a return shot and this continues until a player scores a point and another service has to be made.

 A Let 

   A let can be called for many different reasons if certain rules are not followed. The first being if the ball touches the net when in service, the umpire would then call this a let and the service would be retaken. Another reason a let would be called is if the service is made when the opposition is not ready and they have not attempted to strike the ball or if playing doubles the partner has not tried to strike the ball. If there is a disturbance outside of the player’s control that it results in them failing to return a shot or make a service, the same for if the umpire or assistant umpire interrupts the game.  

The Order of Serving, Receiving and Ends

   In order to start the game the decision of who will serve first and who will start at which end needs to be decided. Therefore the decision for the initial order of serving starts with the winner of the lot. Once they have chosen whether to serve or receive or which end to start at the opposition will decide the other choice.  Once two points have been scored the receiver of the ball then becomes the serving player until a further two points have been scored. As already discussed in the scoring system, unless both players are on 10 points at the end the service is swapped around after only one point. Once the first game has been played the player who served first in the previous one shall receive in the second. The same goes for starting at a particular end; in the second game they must swap ends so they start at the opposite end to the first game.  

Out of Order of Serving, Receiving or Ends

   There are a few reasons why an umpire may interrupt play; the first being if a player serves or receives out of turn. The umpire would immediately stop play and the player who is supposed to be in service at that particular time (determined by who started and what the score is at that moment), would restart play by serving.  The same applies for if the players had not swapped ends when they were supposed to. The umpire again would disrupt the play and players will change to appropriate ends, starting with the player who is supposed to be serving depending on the score at the time and who took the first service. All the points scored before the discovery is made are reckoned.

The Expedite System

The expedite system only comes into play when the time limit has been reached (10 minutes) but has not yet been finished or if both players or pairs request it earlier in the game. However, if both players or pairs have reached 9 points then this system is not invoked. There are two different ways the expedite system is invoked; if the ball is in play then the game is interrupted and resumes with service from the player who served in the previous rally which was stopped. Conversely if the ball is out of play then the player who received the ball in the previous rally will take the service. During the use of the expedite system players only serve for one point until the end of the game.

Safety & Facilities

The ITTF have certain rules for table tennis facilities. The playing conditions have to meet specific requirements, these are as follows:

  • The space in which the game will be played is not to be smaller than 14m in length, 7 meters wide and 5 meters high.
  • The playing area must be enclosed with a barrier that is about 75cm high, this separates playing areas and spectators. The barrier should be a dark colour and same all around.
  • If several tables are in use then it is important that all areas have the same lighting level, and background lights should not be brighter than that of those over the playing areas.
  • The light source above the playing area must not be less than 5 meters above the floor.
  • The flooring should not be light coloured and not be made from, brick, ceramics, stone or concrete. The flooring must be made out of wood or a synthetic material approved by the ITTF.

These rules apply to only two people   playing and to elite performers, for primary users who are not at international level; the rules can be relaxed a little bit. The diagram on the right shows a typical playing arena.

   It is extremely important to follow safety rules for table tennis, these involve making sure the floor is not slippery, i.e. the ...
