Double Olympic champion Kosuke Kitajima of Japan has set a world record in the men's 200-meter breaststroke.
Kitajima has clocked a time of 2 minutes, 07.51 seconds at the Japan Open on Sunday, taking almost a second off the previous mark set by American Brendan Hansen in 2006.
It is the 38th world record set by a swimmer using Speedo's LZR Racer swimsuit since it was introduced in February.
Kitajima, who won the 100 and 200-meter breaststroke at the 2004 Olympics, had also set two new national records at the meet.
Kitajima is contracted to wear a Mizuno swimsuit at the Beijing Olympics, but the Japan Swimming Federation will meet Tuesday to discuss the contract.
