6 Reasons Today's Olympic Swimmers are Breaking so many World Records

For some reason every swim event in this Olympics is a record smasher. And it isn't just Michael Phelps who's seconds ahead of that daunting green world record line. Curious what's making this year's athletes so much faster? Here are 6 possible answers.

1. Tech Doping

Picture 46.pngThe new Speedo LZR RACER suit, which was developed by scientists from NASA, "feels like a rocket coming off the wall," said Phelps in a team interview. "The water just runs off the suit." The suit has "ultrasonically welded" seams that mimics a shark skin, holds in the swimmer's abdomen in the best position, allowing him to take in 5% more oxygen, and takes an athlete 30 minutes to get into!

2. The Pool Depth Matters

The pool in Beijing, known as the "Water Cube," is 3 meters deep, instead of the previous depth of 2 meters. This allows swimmers to dive deeper and continue their push off "dolphin kicks" for a longer period of time. Olympic medalist and commentator Rowdy Gaines says, "It's just deep enough to where the waves dissipate (and) the turbulence dissipates down to the bottom."

3. Empty Pool Lanes

There are ten lanes in the Water Cube, instead of the usual eight, leaving the outside lanes open. This reduces turbulence and enables swimmers to go faster. "It's by far the fastest pool in the world," Gaines says.

4. More Time to Practice

Sponsorship for swimming has increased massively, which allows athletes to practice more. Mark Spitz, the Olympic swimmer with the most gold medals before Phelps, retired at 22 due to his inability to make a living as an amateur athlete. Back then, the Olympics only allowed amateur athletes to compete. Phelps, on the other hand, is now 23 has an estimated annual earnings of $5 million, and will be awarded an extra $1 million dollar bonus from Speedo if he reaches or beats Spitz's record.

5. Old-fashioned Doping

Gary Hall Jr., previous Olympian 50-m freestyle champion, seems to think so. "Can suit technology distract from another issue?... I'm telling you this, I train with an international group of swimmers and all of them have stories and a few of them have had offers." Hall likens today's "blame it on the suit" situation to that of the '76 East German women's Olympic swimming team. Though, he seems to be the only one speaking out about this so perhaps he's just bitter he didn't qualify for Beijing.

6. The Secret Benefits of Math

Professor Timothy Wei, of Rensselaer Polytechnic Institute in Troy, N.Y., helped develop top-secret, state-of-the-art equipment and mathematical techniques that USA Swimming coaches have been using to help to make swimmers go faster. He uses water flow diagnostic technologies to see how each swimmers' motion affects the flow of water. The whole thing is explained here in this video.
