Olympic Swimmers Emulate Sharks & Dolphins

While many Olympians go through excruciating lengths to shed milliseconds off of their race times, the U.S. Olympic Swimming Team have called on a new focus - that is, emulating the natural technique of the best and most powerful swimmers in the world: sharks and dolphins.

From suits to strokes, coaches, researchers and other advisers are making sure that their athletes benefit from fish and marine mammals' natural swimming abilities.

"Some of our athletes are now wearing what are called 'shark skin suits,'" Russell Mark, biomechanics coordinator for U.S.A. Swimming, told Discovery News.

"These aren't made of actual shark skin, of course, but they are slippery in feel, like sharks, and they make the wearer move faster than normal in the water by reducing friction and drag," he explained.

Mark also indicated that excelling at the dolphin kick can make or break a swimmer's race.

"This is when swimmers push off walls and swim underwater without moving their arms, very similar to how a dolphin swims," he said.

The move emulates how dolphins zoom through water by moving their flipper in an up and down motion. Sharks, in contrast, move side to side. Humans are mammals like dolphins and the up and down undulating motion propels people as it does dolphins. The dolphin kick is one of the most powerful moves among professional swimmers.

Sharks are some of the world's fastest swimmers. One impressive species is the shortfin mako, which has been reliably clocked at 31 miles per hour underwater. Everything about this fish is designed for swimming in short bursts of perfection. It has a streamlined body, a crescent-shaped tail supported by keels and a water-cutting, pointed snout.

Tangalooma Wild Dolphin Resort on Moreton Island. About 8 to 10 dolphins come in each evening for feeding. The research team manage this each day allowing resort guests to feed the dolphins in a controlled way.

They feed the dolphins about 10% of their daily requirements, meaning the dolphins do not rely on this food source and continue to hunt in Moreton Bay in their respective pods.

Whilst coming in to feed the researchers can witness and record the behaviour of the dolphins first hand. Particularly valuable research as these remain wild dolphins.

While visiting the Mirage Hotel in Las Vegas..we went to one of our favorite places..The Dolphin Habitat. While I was in the underwater observation area I was able to take this photo using a polarized filter. Photographing the dolphins never gets old, and they always seem to be smiling!

Good stuff, however, i'm pretty sure sharks and dolphins are actually emulating this guy (my little brother).

There were 3 really near the shore...just playing with the waves. Unfortunately by the time I got the camera out and focused, this was all I got!!!! Last time I saw them this close I got the whole pod....a much better shot!!!

This photo was taken in Bora Bora, French Polynesia on May 11, 2008. My husband and I were actually in the water with them! It was AMAZING. We used the Olympus Stylus 850 SW underwater camera.

This is a nationally ranked swimmer in Ontario Canada. I shot this of him late spring 2007 - in a very cold Lake Ontario!
His stride and kick is amazing. This is one of my favourite shots.

This pool is at the Golden Nugget in downtown Las Vegas, NV. You can see the pool in front of the shark tank, and the water slide that goes through the tank as well.

It was amazing to see these trained dolphins jumping and doing tricks in sync, I would recommend Sea World Florida to be the place top of your list to go if you visit the area.

We were on a cruise in Captiva Island. 3 dolphins followed the back of the boat. We saw dolphins in Lighthouse beach on Sanibel island. They were awesome to watch!
