Poly Balls: Table Tennis Balls Are Changing

Table tennis balls are changing! Starting on July 1st the old celluloid balls will be replaced by new plastic or poly balls. There seems to be quite a lot of confusion surrounding this change so here is what you need to know.

Why Are the Balls Changing?

The change is being introduced by the ITTF, the International Table Tennis Federation. Initially, the change from celluloid to plastic/poly balls was said to be important due to the "celluloid crisis" and the potential dangers of celluloid, however, ITTF President Adam Sharara has since admitted that the real reason for the change is to reduce the speed of the game in an attempt to make the sport more viewer-friendly.

The following is a quote from Sharara...

From the technology point of view, we're going to reduce speed. In fact, we're developing a technology  test, which'll have a bounce limit. If you see Chinese players performing the stroke, it's difficult to see the ball. This has to slow down. We're also changing balls. FIFA made the balls lighter and faster, but we're changing balls from celluloid to plastic for less spin and bounce. We want to slow down the game a little bit. It'll come into effect from July 1, which, I think, is going to be a very big change in the sport.

How Will They Affect Table Tennis?

The ITTF have conducted a study, with the help of ESN, to try to answer that very question. It is a comparison of the plastic (poly) balls and celluloid balls, using an evaluation of the difference for rebound on a racket and also player perceptions.

In summary, here is what they found...

  1. Higher rebound: Results from direct measurement and from players perceptions is that the new poly balls have a higher rebound (read: higher bounce) off the table than the standard celluloid balls. This means the ball is going to be higher than you would expect, and you would assume, easier to attack/more difficult to keep tight.
  1. Slower speed: It sounds like further testing needs to be done in this area but early indications show that the poly balls are slower than the celluloid ones. This could be because they are ever so slightly larger (apparently they are a true 40mm ball and the current ones are slightly smaller than 40mm), are lighter in weight and/or there is additional air resistance because of the difference surface material of the ball.
  1. Decreasing speed at topspin strokes: The test players felt that they were receiving a slower ball when using the poly ball from a topspin stroke. It seems that some of the speed is lost either during flight or on contact with the table when the ball bounces. 

In conclusion, it seems that the changes are relatively small. However, in a sport like a table tennis, where players are so close to each other and millimeters can be the difference between a shot going on or missing, these small differences can be quite important. 

I guess that players will get used to these changes and adapt but that will surely take time.

The biggest conclusion I took from the study was that they weren't really sure why the ball was reacting differently. It seems like they aren't even sure if the change will have the desired effect of slowing down the game and making it more viewer friendly. They certainly need to spend a little more time investigating this in my mind. It would be a huge waste of time and money if the new ball made the game "different" but didn't actually make it any slower or easier to watch/understand.

Want Some More Information?

We still haven't seen any poly balls from the big brands yet (Butterfly, Nittaku, Stiga etc.) and there is a good chance that the balls will have improved in quality by the time they are introduced.

 

A few people have managed to get their hands on some of the Palio poly balls and give them a try. If you would like to watch the PinkSkills review and comparison video of the Palio poly ball vs a standard Nittaku celluloid 3-star, click here.

I hope that you now know a little bit more about poly balls when they will come into effect, why they have been introduced and how they will likely affect the game. 

What are your thoughts on the new poly balls? Please leave a comment and let me know.
