Some rules that may surprise you. 1. You CAN double hit the ball (of course intentional double hits/soccer plays are illegal) 2. You CAN hit the ball with any part of your playing hand(while holding the racket) 3. You CAN hit the ball with any part of your racket including handle Ball hits hand then racket, legal! Ball hits hand twice, legal! Ball hits racket then hand, legal!

The double hit rule was implemented in recent years. But I don't think many ppl know that.

so..say your opponent hits the ball...you go to block it hits the back of your hand..you can then take another swing at it and hit it with your paddle?

No. It has to be ONE swing. You can't assist to yourself |

If you're taking a second swing, that would be considered intentional. Soccer trapping/carry plays/intentional double hits are not allowed. I don't think it's humanely possible to intentionally double hit unless you're stopping the ball/trapping the ball in soccer. Your hand reaction time would have to be .01 ms. But let's say you are superhuman, it would make more sense to use your insane reaction time to hit an easy winner, than going for an unreliable and inefficient double hit.

Shucks... I was going to invent the assist and winners stat or as they say in other sports, a "double/double". Thanks. |

I wish this rule was more known. I almost got into a fight with some fat kid because he was wrong and I was right. Damn you ittf rules constantly changing!

Rule was changed in 2008 (following a long standing example of tennis and badminton). So it's not very recent - also it is one of just a few ITTF changes which actually make sense.

I had to make a ruling as an ump once where one player accidentally hit it with his hand and the other stopped playing, thinking it was an illegal hit. I got some pretty incredulous looks when I ruled the point against him

To clarify, although the double hit rule is also applicable to tennis, if one of the two hits makes contact with the hand, the point is awarded to your opponent. Both hits have to make contact with the tennis racquet for the shot to be legal.

The secret of consistency in sports is prolonged contact, which can cause double-hitting. Prolonged contact can be achieved by applying a jumpulse, which is a sudden change of force, at the precise moment of contact (http://double-hit.com; http://jumpulse.com; http://jumpulsetennis.com). Actually, double-hitting is the best way to practice prolonged contact. I have published a book in 1978 on tt, and I'm glad to see that tt rule is no longer violating physics! Double-hitting was legalized in tennis since 1980s. Golf has yet to change its rule on double-hitting to obey physics.

Rules cannot "violate" physics anymore than you could "jumpulse" (there is simply no such word). It is really laughable to see phrases like "Golf has yet to change its rule on double-hitting to obey physics." as if golf balls somehow manage to NOT obey physics. As well as a strange idea that changing the rules of golf (purely bureaucratic matter which will not surely be able to change the universal laws of gravity, reflection and such) might make golf suddenly start "obeying" those laws. Please read your stuff before you post, OK? |

Presumably it was his racket hand - otherwise the incredulous looks would be justified. :^)

Dear Jim,
Thank you for your correction. The correct word should be observe, not obey. However, I could be the authority on Non-violable, being the founder of post-science: *** Furthermore, the wording of the rule should not be deliberately (2.10.1.6 if an opponent deliberately strikes the ball twice in succession;) because deliberately practicing double-hitting is the best way to learn prolonged contact. The tennis rule is more scientific: double-hitting is legal within one smooth stroke. I’ve post a discussion at a theoretical physics group to challenge physicists on the solution of touch or prolonged contact: *** There are over thousands of my students in tennis and table tennis can double hit a ball and learn it within 15 to 30 minutes. The following is a video illustrate definitively double-hitting is possible: *** where the racket moves faster than the ball. Hugh *** |

I received my PhD in plasma physics at MIT and did postdoctoral research at the Courant Institute of mathematical sciences for 3 years. I worked with Paul Feyerabend and Benson Mates for 8 years in the philosophy department at UC Berkeley. I wrote Table Tennis Scientific Analyses in 1978, which was bought by all major sports manufacturers (letter to prove it), predicting double-hitting by good players and The Jumpulse Stroke in 2008 which was bought by almost all the coaches of professional players after writing a post on jumpulse on tennis.com with over 10 times views than the next highest view.
Please state your qualification, Jim. If you ban this, it will be a historical record. Please state your true identity and be responsible for your decisions. Where are my videos? |

Regardless of your qualifications or mine, when I see absurdity I call it absurdity. But that's just me... BTW, please let us know names of the famous coaches in table tennis who bought your book on the "jumpulse". We know quite a few of them here and we can ask them directly what they thought of it. Could be an interesting test. |

I specifically asked about table tennis coaches, not tennis coaches - I doubt there are people here on the forum who know coach Wegner and can ask him questions about your book. Top level TT coaches, now that would be a different matter - I am sure that we have plenty of forummers here with access to almost all of them (residing in the US, of course). |

Please re-post the previous post with valuable links, even though I appreciate Jim's candid criticisms:

I watched the Del Potro backhand video on youtube - why do you say that was a double hit? It looked like clean hit, with the racquet accelerating on contact.
I am missing the concept, links are very confusing.

Actually no, I just glanced at this link: This explains it more clearly. I noticed this when watching Richard Gasquet practice. It appeared he was not hitting the ball, it's hard to describe but sort of cupping it and throwing it back - but with huge amount of speed and spin. I thought it might have been the equipment or something. Another time a TT friend who takes lesson from a former world ranked TT player - told me his coach told him to hold the ball on the racquet and then fling it back rather than hitting it. I didn't understand how it's done. I am thinking "jumppulse" is addressing these issues. Not sure it's true or not but doesn't hurt to check it out. |

Dear jrscatman,
Thank you for raising a good and subtle question: “I watched the Del Potro backhand video on youtube - why do you say that was a double hit? It looked like clean hit, with the racquet accelerating on contact. I am missing the concept, links are very confusing.” Double-hit is hard to see, but when the racket can move faster than the ball, it becomes a definitive prove of the possibility of prolonged contact. When the racket is accelerating during a prolonged contact, the acceleration has to slow down sometime and the ball might microscopically oscillate in and out of the ball. You can try double hit by 1. Moving your racket slowly to a standing ball (zero velocity), 2. Upon contact, swing your racket with as much acceleration as possible (you are applying a jumpulse, a sudden change of force), 3. End the swing with an extreme follow through (this is the real reason for follow through). Please report back to me, if you are successful. Thanks. Hugh |

My other coach friends in table tennis are:
Chung Tse-dong (3 times world champion, and my brother actually interviewed him recently) Liang Guo-Liang (The top coach in Europe, for a while, and he received my first copy of the draft of my TT book in 1971, when he visited UN) However, the best way to convince yourself the importance and the possibility of double-hitting is to try it and report back if you cannot do it. |

I was twice the table tennis champion at MIT. When I got my championship, Lin Ming Chui was also there. He challenged me to a private duel, which was watched by all the ping pong player at MIT (150 team x 5 per team). I beat him 21-18, 21-18. Chui is a tt coach, and his son was ranked at the top, recently. The highest ranking for Lin- Min Chui was 3 in the USA beating lee Doa Jung, long age when we played, also # 8 in Hong Kong, when he was young.
