Equipment
• Table Tennis Racket
A table tennis racket is made up of two distinct parts - a wooden blade which incorporates the handle and table tennis rubbers affixed to each side of the blade using special table tennis glue
Most rackets are actually all very similar in size - about 15cm (6 inches) across and 25cm (10 inches) long including the handle.
.
Equipment
• Table
The table is 2.74 m (9 ft) long, 1.525 m (5 ft) wide, and 76 cm (30 inch) high with a Masonite (a type of hardboard) or similarly manufactured timber, layered with a smooth, low-friction coating.[15] The table or playing surface is divided into two halves by a 15.25 cm (6 inch) high net. An ITTF approved table surface must be in a green or blue color..
.
Equipment
• Ball
The international rules specify that the game is played with a light 2.7 gram, 40 mm diameter ball.
The rules say that the ball shall bounce up 24–26 cm when dropped from a height of 30.5 cm on to a standard steel block thereby having a coefficient of restitution of 0.89 to 0.92.
The 40 mm ball was introduced after the 2000 Olympic Games.
Basics
• Grips– Pen Hold
• The penhold grip is so-named because one grips the racket similarly to the way one holds a writing instrument.
• The style of play among penhold players can vary greatly from player to player.
• The most popular style, usually referred to as the Chinese penhold style, involves curling the middle, ring, and fourth finger on the back of the blade with the three fingers always remain touching one another.
Basics
• Grips– Shake hand
• The shakehand grip (also called the "shakehands grip") is so-named because one grips the racket similarly to the way one performs a handshake.
• The grip is sometimes referred to as the "tennis grip" or the "Western grip," although it has no correlation to the Western grip used in tennis.
• The shakehand grip is traditionally popular among players originating in Western nations and South Asian nations.
Basics
• Strokes– The Drive
• Drives, a light topspin stroke that produces a low ball trajectory, are the primary offensive strokes in table tennis.
• One employs drives to force errors and to set up winners. The mastery of both the forehand and backhand drives is important because it will give your opponent less options when using attacking strokes of his/her own.
• In executing this and all other offensive strokes, the usage of the entire body in unison is important for consistency and power. Keep in the ready position until you are ready to execute the shot and remain relaxed but responsive (this is very important).
Basics• Strokes
– Forehand Drive• Keep the upper arm close, but not flush, to the torso. The
forearm(form a rough 90 degree bend with the upper arm) should be drawn back to the 3 o'clock position, and let the waist turn naturally along with the arm(this is where relaxing is important).
• Shift your weight toward the right foot at the same time. While shifting your weight back to your left foot, swing forward with a slight upward motion, with the waist providing additional force in the swing.
• Use the elbow as a pivot point; it should not move so much up and down, but also should be allowed to move slightly forward in the follow-through.
• Contact with the ball should be made slightly to the side of the body after the top of the bounce.
Basics
• Strokes– Forehand Drive
• Make sure the paddle is somewhat closed(or facing downwards at an angle), and remains that way throughout the stroke. Follow-through should finish when racket is parallel with the left shoulder. Immediately return to the ready position. The left foot should be slightly in front of the right for support.
Basics
• Strokes– Backhand Drive
• From the ready position, the waist turns left with the racket pointing towards the 9 o'clock position.
• When following through, contact with the ball is made in front of the body, slightly after the top of the bounce. Let the elbow again act as the pivot point, and snap the forearm forward in a slightly upward direction.
• Make sure the paddle is closed. Follow-through should finish naturally (about 12~1 o'clock) after contact with ball. The left foot should be slightly ahead of the right.
Basics
• Strokes– The Push
• Pushes are the basic backspin shots, used to change the pace of an exchange or to return certain very low and close shots such as backspin serves.
• A generally defensive shot, it allows placement anywhere on the table that is difficult to attack when executed properly. All pushes should be done with the right foot stepping in.
• The ball is contacted right after the bounce with an open racket. How open the racket is depends on the intensity of backspin on the ball. Heavier backspin requires a more open racket to return over the net. Try to keep the ball low, varying the amount of backspin and racket angle.
Basics
• Strokes– Forehand Push
• Bring the racket slightly up and back, while keeping the elbow at your waist. Bend the wrist back. Swing forward with a downward motion, and when the racket reaches the ball snap the wrist forward for extra racket speed.
• With an open racket, graze the bottom half of the ball. An ideal contact point is right after the ball bounces. Never push a ball at the top of the bounce, because the resulting return will pop the ball high enough for the opponent to execute a smash. Try to hit the ball in front and slightly to the right of your body. Follow through forward and slightly down, and return to the ready position.
Basics• Strokes
– Backhand Push• Bring the racket slightly up and back, close into your stomach
while cocking the wrist back. This time try to contact the ball directly in front of your body, and remember to keep the elbow still while the forearm and wrist move forward and down. Graze the bottom of the ball and follow through.
– Block• Blocking allows a player to use the opponent's force against
him/her, and is done immediately after the bounce so that maximum control and speed are retained. Adjusting the racket angle depends on the severity of topspin on the ball; the more topspin there is, the more you should close the racket. Being essentially a cut-down drive, there is very little backswing and follow-through.
Basics
• Strokes– The Smash
• The smash, or kill, is the put-away stroke of table tennis. Any ball that is high enough and close enough to the opponent's side can be smashed, although some opportunities are better than others.
• Smashing combines waist, forearm, and wrist movement to the fullest extent. A good smash is very hard to return, but it can be done. Do not dawdle after you have executed a smash. The ball is contacted at the top of the bounce at its highest point.
Basics
• Strokes– Forehand SmashSimilar to the drive, the key differences include:
• A longer backswing • Greater weight transfer during swing • Faster, more intense snapping of the forearm when contacting ball • Depending on ball height and position, the racket is closed more
than usual to keep the ball in the court • Longer follow-through, but don't forget to anticipate a possible
return!
Basics
• Strokes– Backhand Smash
• Again, use the guidelines above and apply them to the backhand drive. Be sure to snap the wrist more as you contact the ball and finish in a long follow-through
Basics
• Strokes– Basic Service Techniques
The following are the basic rules of service: • The ball must be held above the table level in order for the
opponent and umpire to see it. • The ball must be held in the palm of the hand with fingers
stretched, and tossed vertically at least six inches. • The ball must be struck only on the way down. • The ball must be struck behind the end line.
Basics
• Strokes– Basic Service Techniques
Imparting spin on these serves should be concentrated mostly on the wrist.
• Backspin- just like pushing or chopping, a backspin serve is executed with an open racket slicing the bottom of the ball.
• Topspin- like driving, topspin serves can be done hitting with a flat racket, or like looping, where the player grazes the top of the ball with a closed racket for more spin.
• Sidespin- simply hit the back of the ball in a left-to-right or right-to-left motion, as desired. To make the stroke easier, try holding the racket in front of you and brushing the bottom of the ball in a pendulum motion.
Rules
• 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.

Rules
• The Table– 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.
– For doubles, each court shall be divided into 2 equal half-courts by a white centre line, 3mm wide, running parallel with the side lines; the centre line shall be regarded as part of each right half-court.

Start Your Play• Warming up helps get your body ready for
the rapid coordinated moves that make table tennis such an intensive sport.
• There are no special or unique exercises; it's just like warming up before playing any other sport
• A light jog, jump ropes, and various stretches help loosen your muscles and get you "in gear" for optimum performance.
Safety• Warming up before play is important and will
reduce the chances of muscle and joint injuries. It is ideal to start with general warm up like stretching and jogging. Then spend some time on specific warm up like playing gentle shots for the first 2 -3 minutes with another player. Gradually upping the pace and tempo.
• On an average, players need about 15 minutes to warm up themselves. Cooling down after play is important in preventing injuries. Avoid lying down straight after play. It is good to walk around or just do a few simple stretching exercises to cool down and relax your body.
