6. 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.
.

7. 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..
.

8. 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.

9. 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.

10. 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.

11. 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).

12. 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.

13. 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.

14. 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.

15. 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.

16. 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.

17. 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.

18. 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.

19. Basics
• Strokes
– Forehand Smash
Similar 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!

20. 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

21. 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.

22. 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.

23. Rules

37. 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.

38. 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.
