Michael Anderson, ITTF executive director of Education and Training, published on his blog "Eleven Points" that he visited the Japanese city of Tokyo some days ago. Mr. Anderson explained that he was sent to Japan by the ITTF Executive Committee to deal with some issues about the racket control.
After Beijing 2008, the International Table Tennis Federation prohibited the use of speed glue or any other chemical substance such as boosters due to its toxicity. However, this rule didn't have a good acceptance from players because new glues don't give rubbers the speed and spin that old glues did. However, some players got used to the new glue but others didn't, so they looked for new ways to get more speed and spin, and to cheat the racket control. That's why Michael Anderson was in Japan. He is part of a group that tries to find ways to avoid players from cheating racket control.
Mr. Koji Kimura, ITTF Executive Vice President, hosted an meeting protocol that gathered Japanese table tennis manufacturers. They visited the Tamasu Butterfly plant and also met with the Japanese national team to discuss about the racket control.
Mr. Anderson said that ITTF didn't has a method to measure thickness accurately with the rubber attached to the blade. The ultrasonic equipment that ITTF uses for the racket control is not enough because it doesn't work well with the combination of wood, multilayer rubbers and pimples, added ITTF Executive Director. However, he also commented that research shows that it's possible to detect the use of booster or tuners. The problem is that this would involve a combination of visual inspections, potential lab function, improving the control system and a rule that allows ITTF to order players to separated rubbers from the blade if something indicates that there is some illegality.
The ITTF authority also talked about from the players' point of view. He remarked that players must feel annoyed due to racket controls. The International Federation has voluntary tests and also the compulsory pre and after match test, so players must be under pressure with these controls.
Nowadays, ITTF doesn't have a solution to these problems and it doesn't know neither if the solution will be found. However, the only thing we know is that the International Federation is working on that.
