The number of world records shattered at the European championships and Australian Olympic trials last month may make even the world's best swimmers shake in their swimming suits.

But the Chinese team is not worried and says it has no interest in trying out Speedo's new LZR Racer full-length bodysuits, which some say are responsible for the astonishing records.

With only four months until the Beijing Olympics, 12 out of 13 swimming world records have been set since February 16. Frenchman Alain Bernard broke three world records (the 100m freestyle twice and the 50m once) at the European Championships in only three days, while Australian sprinters set another eight records in their Olympic trials in eight days. All of the swimmers wore LZR Racers.

But Wu Peng, China's top medal hopeful for the Beijing Games, doesn't believe the bodysuit is responsible for the record-breaking performances.

"A swimsuit doesn't generate champions," Wu told Sina.com at the national Olympic trials. "It's your training level and experience that decide your result at the Olympics. A swimsuit is not enough to help you achieve the feat.

"What happened in Australia has no effect on me. I just focus on my training and will try to reach my goals in August."

Even if China's swimmers wanted to wear the new Speedo suits, the team's contract with Nike, which it signed in 2005, makes it impossible. But head coach Zhang Yadong thinks it is a nonissue.

"As far as I know, there are no scientific results that prove the swimsuit is really able to improve an athlete's performance," he said. "I think most professional swimmers don't like to change suits frequently, especially just months before the Olympics.

"Even without the so-called 'magical' new suit, Australia and European countries are swimming powerhouses. Their athletes have been with Speedo for years and they are already used to its products. I think that's why there are so many world records broken in the LZR Racer."
