Strokes of Borrowed Genius
Mimicking Mother Nature’s Swimmers
by Eric Smith

Is that a dolphin? There, plunging through the warm Bay water. Like a dolphin, it arcs in and out of the waves. Like a dolphin, it pumps its body up and down. And dolphins were sighted just a month ago in Rockhold Creek. But look again. This dolphin is slow, awkward, and a little … pink.

Not a dolphin at all, but a swimmer! A person in a bathing suit, swimming cap and goggles, swimming the butterfly.

The butterfly resembles the movement of dolphins, with its arcing stroke and powerful, wiggling kick. Elite swimming humans can make it up to four and five miles per hour doing the butterfly. That’s fast, but dolphins, with their own variation (without the arms) can make it up to 22 mph.

With two feet, two arms, no webbed limbs or flippers and without a streamlined body shape, people are better adapted for walking than swimming. So often we imitate those animals that are designed for water when we swim.

The kick used in breaststroke is called the frog kick because it resembles the bend-at-the-knees, thrust and squeeze kick used by our green, lillypad-hopping friends.

Beginning swimmers sometimes learn to swim on their backs using the T-stroke, stretching their arms straight out then pumping them back to their sides. It is much like the billow-and-push motion used by jellyfish.

One Olympic swimming coach, Gennadi Touretski, even takes time to study the motions of fish to learn the best way to move through the water. And swimmers he coached won Olympic gold medals using his techniques.

Whether you want to win an Olympic gold medal, swim with a pod of dolphins, or just make it safely to the edge of the pool, know that no one knows swimming better than Mother Nature. So have some aquatic animals give you a lesson. Perhaps not jellyfish. Most don’t like their … teaching style. (I’d stay away from the sharks, too!)

History Crawls Forward:

In 1837, when modern competitive swimming started in London, England, everyone swam the breaststroke and sidestroke. Then, some American Indians swam in a London meet in 1844. The British said they moved their arms “like a windmill,” a new stroke that was “totally un-European.” Even though Flying Gull beat everybody else by 30 seconds to win a medal with this early form of front crawl, Europeans didn’t catch on. It was Australian Richard Cavill who finally convinced Europe about freestyle. They called it the “Australian front crawl.”
