  17. 17. The GripShake hands grip- Shake hands gripforehand side. - backhand side
  18. 18. Shake hands Grip• Start by “shaking hands” with the racquet handle. Now extend your index finger along the bottom of the blade. This gives extra stability to the blade.• Now check the thumb. It should be along the bottom of the blade, on the opposite side from your index finger. The thumbnail should be perpendicular to the blade. The soft part of the thumb should not be touching the blade. Now check the crook of the thumb and forefinger. The blade should rest there, perhaps a little to the index finger side but never on the thumb side. The exact placement can be varied somewhat.
  19. 19. Shakehands Grip• With this grip, there are now twoanchors – the thumb and indexfinger and the last three fingersaround the handle. In addition, themiddle finger helps support theweight of the blade. With thefingers in proper position, the bladeis very stable. When hitting abackhand, the thumb gives a firmbacking; when hitting a forehand, theindex finger does this.
  20. 20.  The penhold grip is so-named because one grips the racket similarly to the way one holds a writing instrument.Penhold 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.
  21. 21. Footwork and Stance• A good stance in receiving is about 2 to 2½feet directly at the back of the center line of the court.• Stand with the feet a little apart and with the left foot forward.(for a right – handed person).
  22. 22. Getting Started Practice bouncing the ball on the racquet. developed their hand/eye Coordination have Them try bouncing the ball on the racquet but using alternate sides ofBouncing a ball on a racket helps increase the racquet.coordination for young beginners.
  23. 23. Simple Serves Forehand Topspin Serve
  24. 24. Forehand Topspin Serve On all serves, the points that should be stressed are: • Serve with a general plan in mind. If you want a topspin return, serve topspin. If you • Keep the ball low. want a backspin return, serve backspin. Of course, • All serves should be this served with as much spin or is just a generality. You can’t as much speed as possible. force your opponent to return the ball the way you • All serves should be aimed want. But you can try. at a particular part of the table, not just served • Make sure the serve is in the general direction of legal!
  25. 25. A topspin serve, have them hold theracquet so it is perpendicular to the floor.Have them contact the ball on the backtowards the top with an upward andforward motion. Show them how to grazethe ball for maximum topspin. This servecan be done either forehand or backhand,whichever is easier for the child. However,they should eventually learn to do it bothforehand and backhand
  26. 26. Simple Serves Forehand Backspin Serve
  27. 27. A backspin serve, have him/her hold theracquet so the hitting surface is pointingmostly upward at about a 45 degree angleto the floor. The specific angle depends bothon the type of racquet surface, the speed ofthe racquet at contact, and how finely theball is grazed. This is true on all serves, butespecially with backspin and sidespin.
  28. 28. Contact the ball on the back towards thebottom with a downward stroke. Again,stress that the more you graze the ball, themore spin. This serve can also be done bothforehand and backhand, and both waysshould be learned.
  29. 29. BackhandTopspin Serve
  30. 30. Backhand Backspin Serve
  31. 31. Forehand Sidespin Serve
  32. 32. Backhand Sidespin Serve- similar to a backhandbackspin or topspin serveexcept racket movessidewaysinstead of down or up
  33. 33. The Strokes Techniques or Offensive strokesReady Position for Strokes•You should stand at the table.•Have your playersstand in a slight crouch with the kneesslightly bent.•Weight should be on the balls of the feet,Which should be slightly farther thanshoulder width apart.
  34. 34. FOREHAND TOP SPIN SHOT• This shot is basic offensive drive accomplished by striking the ball with a vigorous motion either on the dropping part of the bounce or at the height of the bounce. Make an upward- forward movement of the racket in order to make a top spin. You can use this shot on high- bouncing returns. Be sure to put more weight on your forward foot to add power to the shot.
  35. 35. Forehand Drive
  36. 36. Forehand DriveRotate the body to the right at thewaist and rotate the arm back atthe elbow. The elbow should staynear the waist. Weight should berotated to the right foot.During the backswing, the racquetshould open slightly. The racquettip and arm should point slightlydown, with the elbow at about 120degrees or so.
  37. 37. Forehand DriveStart by rotating the weightforward onto the left foot. Thisinitiates the forward swing. NowRotate the arm on the elbowforward, keeping the elbowalmost stationary. The elbowangle should decrease to about90 degrees. The waist shouldbe rotated forward. Backswingand forward swing should beone continuous motion.
  38. 38. Forehand DriveContact should be made atThe top of the bounce, in frontand slightly to the right of thebody. This will close yourracquet as it contacts the ball.The racquet should rotatearound the ball, creatingtopspin.Sink the ball into the spongeusing the upward and forwardmotion of the racquet. Strokethrough the ball - do not stopthe swing at contact.
  39. 39. Forehand DriveThe racquet goes roughly to theforehead or around the right eye,similar to a salute. Taller playersFollow through lower. Shorterplayers (and most kids) followthrough a little higher. Weightshould be transferred to the leftleg, with the shoulders and waistrotated to the left.
  40. 40. Backhand Drive
  41. 41. The Backhand drive• Rotate the lower arm and racquet towards the stomach, bringing the racquet down to about table level. The racquet and arm should point slightly downwards, with the elbow at about a 90 degree angle. The racquet should open during the backswing. The elbow itself stays stationary. Do not use the shoulder, legs, waist, etc., at any part of the stroke!
  42. 42. The Backhand drive• Rotate the lower arm and racquet forward and slightly up on elbow. The elbow moves forward just enough to keep the racquet going in a straight line.• At contact, snap the wrist up and over the ball, closing the racquet. The racquet rotates around the ball, creating topspin. For extra power, stroke straight through the ball with less spin, sinking the ball straight into the sponge and wood.
  43. 43. The Backhand drive• The arm continues to extend forward and slightly up, with the elbow extending forward to keep the racquet going in a straight line until the very end of the follow-through. At the end of the stroke, the racquet should point a little to the right of the direction the ball was hit. The elbow is now almost fully extended.
  44. 44. The Block -Forehand and BackhandBackhand Block Forehand Block
  45. 45. The Block• A block is a simple way of returning a hard drive.• A block can be done either forehand or backhand.• the block is that you should contact the ball earlier. Take it right off the bounce.• The block is most effective as a way to return an opponent’s drive as quickly as possible so as not to give him a chance to keep attacking.
  46. 46. The Block -Forehand and Backhand• Very little backswing. Just get the racquet into position so that the incoming ball will contact it.• Very little, except on an aggressive block.• The key to blocking is to use the opponent’s speed and spin to return the ball. Contact should be made right after the bounce. Quickness is the key – you don’t want to give your opponent time to make another strong shot.
  47. 47. The Block -Forehand and Backhand• Hold the racquet firmly and let the ball sink into the sponge and trampoline back. At contact, move the racquet forward some, more so against a slow ball than against a fast one.• Although you have no backswing and hardly any forward motion before contact, you do have to follow through. Just move the racquet forward, rotating at the elbow.
  48. 48. The Push shot or Half Volley• The push is a passive backspin shot done against backspin. It is generally done against a serve or push which you don’t want to attack.• It is mostly done with the backhand, as the forehand push is slightly awkward and it is usually better to attack on that side.• The key is to push so the opponent cannot attack effectively. Keep the ball low, place it well, and give it a good backspin.
  49. 49. Backhand Push
  50. 50. Backhand Push• Point the elbow forward, open the racquet, and bring the racquet backward, rotating at the elbow. The elbow should not move much during the stroke.• Rotate the racquet forward and slightly down.
  51. 51. Backhand Push• Beginners should contact the ball as it drops. Let the ball fall onto the racquet, grazing the bottom back of the ball to create backspin.• More advanced players can push quicker off the bounce, but for kids that may be too difficult to control. Top players do it both ways.
  52. 52. Forehand Push
  53. 53. Forehand Push• The elbow should be slightly in front of the body. Open the racquet and bring the racquet backwards and up, almost to the right shoulder. The elbow does not move throughout the rest of the stroke.• Rotate the racquet forward and down at the elbow.
  54. 54. Forehand Push• Contact is the same as on the backhand push. Let the ball drop onto the racquet, grazing the bottom back of the ball to create backspin.• Do not stop at contact. Follow through by extending the arm at the elbow until it is almost fully extended.
  55. 55. Defensive strokes• Forehand Chop• Backhand Chop• Drop Chop• Smash shot
  56. 56. FOREHAND CHOPThis is defensive stroke executed with ahatchet chopping movement. Themovement of the racket begins by hittingthe ball forward downward and finishedwith your arm extended in front of you. Cutthe ball with the blade down behind andunder the ball so that it spins as it leavesthe racket. This is done with much speedmaking if difficult of the opponent to returnthe ball.
  57. 57. BACKHAND CHOPThis stroke is the opposite of the forehandstroke. It is shorter and needs a strong useof the forearm and wrist. Start the strokefrom chin-height and end at about thewrist-height.
  58. 58. DROP CHOPThis stroke is executed by swinging theracket as I making a drive but stopping theforward motion as the racket is almosthitting the ball hit the racket instead.
  59. 59. SMASH SHOTFrom a height of about 2 ft., hit straightforward and downward without spin. This isa kill.
  60. 60. Forehand Loop vs. Backspin
  61. 61. The Loop• a shot with excessive topspin. The spin is produced by grazing the ball in an upward direction.• A good loop is difficult for a beginner to return without going off the end or at least popping up.• It is easier to loop against backspin than against topspin. It is primarily a set-up shot, but it can also be used as a put away shot.
  62. 62. Forehand Loop• With your right foot slightly back, bend your knees, rotate your hips, waist and shoulders backward, and bring your racket and arm down and back by dropping your right shoulder.• Straighten your arm so elbow is nearly straight, with your wrist cocked down slightly.
  63. 63. Forehand Loop• Start the forward swing by pushing off your back leg and rotating your hips and waist forward. Rotate your shoulders, pulling with your left.• Just before contact, snap your forearm and wrist into the ball smoothly but vigorously.• (Beginners shouldn’t use wrist at first.)
  64. 64. Forehand Loop• Contact the ball as it drops for maximum spin and control, at the top of the bounce for faster, more aggressive loops.• Contact is made in front and to the right of your body, immediately after the shoulder and hip rotation.• Contact is a lifting, grazing motion against the back of the ball.
  65. 65. Forehand Loop• Arm should continue up and forward, finishing with the racket somewhere around the forehead or higher. Transfer your weight to your left foot.

  69. 69. The RulesScoring• The game is 21 points.• A game must be won by two points.• Serves are alternated every five points, except at deuce (when they are alternated every point).• The game does not end at 7-0 or any other score except 21 or deuce.
  70. 70. The RulesServing• The ball must be held in an uncupped hand, with the thumb free.• The ball must be tossed up at least six inches.• The net is six inches high and can be used for comparison.• The ball must be struck while it is dropping.• Contact must be above the table level and behind the end line or its imaginary extension.• Let serves (serves that nick the net but hit the other side of the table) are taken over.

  71. 71. The RulesRallying• You may not volley the ball (hit it before it bounces on your side of the table).• The rally continues until someone fails to return the ball.• You may not move the table or touch it with your non- playing hand.• To start a game, one player hides the ball in one hand under the table and the other tries to guess what hand it is in. Winner gets the choice of serving or receiving first (or choice of sides).
  72. 72. The RulesStarting a gameAccording to ITTF rule 2.13.1, the first service is decided bylot, normally a coin toss. It is also common for one player (orthe umpire/scorer) to hide the ball in one or the other hand(usually hidden under the table), allowing the other player toguess which hand the ball is in. The correct or incorrect guessgives the "winner" the option to choose to serve, receive, orto choose which side of the table to use. (A common but non-sanctioned method is for the players to play the ball back andforth four times and then play out the point. This is commonlyreferred to as "play to serve" or "rally to serve".)
  73. 73. The RulesService and returnIn game play, the player serving the ball commences a playThe server first stands with the ball held on the open palm of the hand not carrying the racket, called the freehand, and tosses the ball directly upward without spin, at least 16 centimeters (approximately 6 inches) high.
  74. 74. The RulesService and returnThe server strikes the ball with the racket on the balls descent so that it touches first his court and then touches directly the receivers court without touching the net assembly.The ball must remain behind the endline and above the upper surface of the table, known as the playing surface, at all times during the service.
  75. 75. The RulesService and return The server cannot use his body or clothing to obstruct sight of the ball; the opponent and the umpire must have a clear view of the ball at all times. If the service is "good", then the receiver must make a "good" return by hitting the ball back before it bounces a second time on receivers side of the table so that the ball passes the net and touches the opponents court, either directly or after touching the net assembly.
  76. 76. The RulesService and returnThereafter, the server and receiver must alternately make a return until the rally is over.Returning the serve is one of the most difficult parts of the game, as the servers first move is often the least predictable and thus most advantageous shot due to the numerous spin and speed choices at his or her disposal.
  77. 77. The RulesThe order of play In singles, the server shall first make a good service; the receiver shall then make a good return and there after, server and receiver alternatively shall each a good return.
  78. 78. THE RULESA GOOD RETURN Is when a ball having been served or returned in play shall be struck so that it passes directly over or around the net touches the opponent’s court either directly or after touching the net assembly.
  79. 79. THE RULESTHE PLAY The ball is in play from the last moment it is projected from the hand in service until it touches anything other than the plating surface the net assembly, the racket, held in the hand or the racket hand below the wrist or the rally is otherwise decided as let or point.
