TOKYO — Three Japanese sportswear makers introduced new versions of high-tech swimsuits intended to compete with Speedo's new LZR Racer at the Beijing Olympics.

Mizuno Corp., Asics Corp. and Descente Ltd. presented their new products Friday to the Japan Swimming Federation, which requires national team swimmers to wear the domestic companies' products for contractual reasons.

Since Speedo introduced its new suit in mid-February, 37 world records have been set by swimmers using it compared to only four by swimmers wearing other suits.

World governing body FINA has repeatedly upheld the legality of Speedo's design and will hold a special meeting next month to rule on the legality of new suits designed by rival companies in response to the LZR Racer.

Japan's Olympic swimmers will get a chance to test the new products as well as the LZR Racer at the Japan Open in Tokyo from June 6-8.

Mizuno, which supplied its suits to reigning Olympic breaststroke champion Kosuke Kitajima, developed a new suit using materials that put tighter pressure on the body to decrease water resistance.

Asics presented two types of suits, which makes the pressure on the legs three times tighter, while Descente launched three different types including one manufactured by Italian maker Arena.
