The pool got a little more crowded Wednesday when additional high-tech swimsuits were green-lighted by FINA, the international governing body of swimming.
FINA, at an IOC meeting in Athens, signed off on suits from three companies: European manufacturer Arena, Adidas and Mizuno of Japan. This won't, apparently, be the final opportunity to receive FINA approval for other companies, as there will be one more chance, on June 30.
There are reports that at least two more Japanese companies, Asics and Descente, have new products in line and that Japanese Olympic swimmers will have the opportunity to try those particular suits at a meet in Tokyo, starting Friday.
The U.S. swimming trials begin June 29 in Omaha.
Speedo and TYR previously have launched their own high-tech offerings. Since mid-February, there have been 37 world records (long course and short course) by swimmers wearing the Speedo LZR Racer.
