Where it all started

High-tech bodysuits were first introduced to Olympic swimming in the year 2000 when the Games came to Sydney (remember Thorpedo?). At the time, it was the biggest year for world records in the history of Olympic swimming; 62 world records were smashed. Then in 2008, an unprecedented 79 world records were broken by swimmers wearing one suit: the Speedo LZR Racer. Some argued that it was normal. Others began pointing fingers at the suit.

How they work

Let’s have a closer look at Speedo’s LZR Racer. Speedo partnered up with NASA and the Australian Institute of Sport to create this high-tech supersuit. They tested more than 90 different fabrics, scanned over 400 athletes to pinpoint areas of high friction on the body and then built an ultra lightweight suit with strategically placed polyurethane panels to minimise drag by 5% and suck muscles into the perfect shape (whatever that may be). A “compression zone” around the torso (think of a corset) and other parts of the body serves to improve buoyancy and reduce muscle vibration, allowing the swimmer to conserve more energy. In a sport where victory is measured by hundredths of a second, it could mean the difference between a medal and no medal. Michael Phelps, who is sponsored by Speedo, said, “When I hit the water [in the LZR Racer], I feel like a rocket.” And as we all know, it was enough for him to win the 100m Butterfly final at the Beijing Olympics by a mere 0.01 second:

Winning is more important than money
Speedo offered to make the suit available to all swimmers, regardless of apparel loyalties. Japanese competitors defected to the LZR suit, knowing that any contractual obligations wouldn’t be enforced — doing so would be commercial suicide: If the swimmers lost, the companies would be to blame.

But FINA also allowed rivals to copy the the LZR Racer without fear of being sued by Speedo. And so the swimsuit arms race began. Arena was the first to follow Speedo with a prototype that pushed the definition of tight-fitting fabric. Adidas scrambled to come up with comparable designs. In the end, Speedo—with the priceless endorsement of Michael Phelps—won the race hand over fist: 94% of all swimming races won and 23 out of 25 world records broken were achieved by swimmers wearing Speedo’s miracle suit.

In the end, FINA had two viable options: Allow every country to wear it in violation of their existing equipment contracts, or ban them all. They went with the latter.

So, what’s the problem?

1. Interpreting the rules
Swimmers have never been allowed to use or wear a device that could enhance performance, yet that is precisely what these high-tech suits claim to do. Speedo says their LZR Racer suit, developed “in strict accordance with FINA rules and regulations”, improves a swimmer’s performance by 3%. The new rules state that only “textiles” can be used, but that’s a pretty loose term that can be interpreted in any number of ways. With technology constantly evolving, where do you draw the line?

2. Is it cheating?
Many coaches and officials have equated the suit issue with the doping problems that plagued the sport in decades gone past. What’s the difference between gaining an advantage with a swimsuit and gaining an advantage by taking performance-enhancing drugs? Purists argue that artificially enhancing the performances of swimmers with these high-tech suits amounts to “technological doping”. Australian swimming coach Forbes Carlile campaigned for bodysuits to be banned, saying, “The game was up, it’s chaos, disruption and false records. The sport has lost its way.”

3. Records Will Stand
Records achieved in this suit will be allowed to stand. That means swimmers competing events beyond the start of the ban will have to measure themselves against records set in these supersuits. Michael Phelps once said in an interview: “If we do go back a couple years for swimsuit technology, some of those records may not get broken ever again.” The debate over whether to put an asterisk on records achieved in high-tech suits is hardly a solution.

4. Spirit of the Games

The Japan Times sums it up perfectly:

Not everyone is comfortable with the winning-is-everything ethos. According to the original charter of the modern games, participation is the ultimate good thing. However, the rise of global media and the resulting involvement of a worldwide audience has turned the Olympics from a “festival for peace” into a showcase for superhuman abilities.

The new rules

In July 2009, FINA unanimously voted to ban them all. As of next year, swimsuits that cover the neck, shoulders or ankles will be banned. Suits to be used from 1 January 2010 must be submitted for approval by 1 November 2009, and any future submissions will have to be made 12 months in advance of a major event.

We’ve all soaked a not-so-waterproof gadget or two, and we know that lots of them can come back to life after a few days of drying, albeit sometimes with some unfortunate damage. But dunking a wet gadget in a container of rice (provided the surrounding environment is humidity-free) can absorb excess moisture and reduce the possibility of damage, which can come in handy in these glorious summer months that are so fraught with danger for our beloved gadgetry. Not that we’re suggesting you take your iPhone along with you for a surf, but if you do, this might save your gadget’s life. [Lifehacker]

A U.S. proposal to limit the amount of swimsuit coverage – between the waist and knees for males, not beyond the shoulders or below the knees for females – was overwhelmingly passed by the FINA congress, meeting in Rome during the world championships.

The new rule also says suits shall only be made from “textiles,” but that term has yet to be defined.

It’s about time—I mean, this seemed like such an easy fix. The only problem is that the 108 world records set last year, the 30 set so far this year and whatever records are set between now and 2010 will be allowed to stand. That means swimmers competing in world championship events and the Olympics beyond the start of the ban will have to measure themselves against records set with a major technological edge. Although, I wouldn’t be surprised if those records get marked with a big, fat asterisk somewhere down the line. [SF Gate / Image via NASA]

It won’t be long before summer is here, so prepare yourself for some poolside partying with the Aqua Sounders wireless speaker and mood lighting ball.

Indeed, the Aqua Sounder will not only transmit your MP3 player tunes from a dock positioned up to 50 metres away, it will also provide ambiance with two LED mood lights. It’s completely submersible, and you just might be tempted to use it for a game of pool dodgeball, but I would have to caution against it. [Grace via I4U via DVICE]

The images above illustrate two design concepts: the first is focused on amplifying a swimmer’s lower body movements in the water—like a motorised version of swim fins. The second concept goes a little further by attempting to mimic how a penguin uses its upper body to swim. Apparently the project is still in development, and since the image illustrates that the motorised lower body fin has actually been tested, I am going to assume that is the direction they have decided to pursue. That’s probably for the best. [IHMC via Wired]

The Lunocet weighs about 1.1kg out of the water, but in the water it’s positively buoyant. Constructed from silicon wrapped in carbon fibre with a titanium footplate, the system gives you the same power on a downstroke as an upstroke. Coupled with a pair of strong legs the monofin could theoretically generate enough power to drive a human completely out of the water–yes, real life dolphin acrobatics at last.

So is the Lunocet worth its US$1250 to US$1800 pricetag? We don’t know, but it sure sounds a whole lot better than actually training. And we doubt that we’ll be getting access to DARPA’s swimming tech anytime soon. [Lunocet]

Originally, his team wanted it to have porous walls, like a sponge, that would really absorb waves–way more than the pool’s two extra lanes and gutters, which are actually pretty standard. The spongey walls would have been so effective in neutralising speed-killing waves, it might have profoundly changed the sport. But the Chinese didn’t want to pay for them.

The other change, rejected by swimming’s governing body, were new starting podiums with a flap, giving swimmers something to push off from, which testing showed cut a tenth of a second off times. They’ll debut at next year’s world championships. Guess you can’t fight progress. [Radar]

In response, Arena fired off a prototype super suit of its own, complete with plastic inserts and who knows what else. “A new era in the sport kicks off today,” said Christiano Portas, the head of Arena. “We can fight for ethics but we stood alone when it came to everyone saying that the word ‘fabric’ in the rules was just a generic term. Now we explore many other things.” My money is on one of these custom-built Columbian submersibles, how about yours?
