In addition, the rowing uniforms use a "No Sew" laminating technology in the leg hems that puts the fabric together without the bulky seams of sewn garments. This also helps reduce chaffing and irritation, Nike claims.
One of the biggest challenges Athens poses is heat. With sweltering temperatures routinely topping 100 degrees in the summer, several companies are developing "beattheheat" athletic wear, some of it for events, some for warmups, and some just for hanging out in the Olympic Village.
For example: Adidas is applying to clothing the ClimaCool technology it pioneered in running shoes. Using threedimensional fabric construction, the company has come up with jerseys and other garments that use the latest techniques and fibers to absorb sweat and conduct heat away from the body. To improve the cooling aspects of ClimaCool, Adidas used computer technology to map the body's sweat zones, and then placed ventilation in those zones.
Strange as it may sound, the Australian Olympic Team hopes to conquer the heat with wool. The nation's sheepcentric powerhouse, Woolmark Co., will provide allnatural wool garments that breathe, absorb moisture, and stay dry against the skin.
Because shoes trap so much heat in track and field, research continues to make them more breathable. Adidas, for one, has added venting under the foot through the midsole. And by placing polyester and polyurethane film under the ball of the foot, the company has developed new shoes that reflect away different wavelengths of light and heat coming from the surface of the running track, even before they get absorbed in the shoe. The film will be used in shoes for longdistance races and the marathon.
Consumers eventually will see derivatives of hightech athletic wear in sporting goods stores.
Most items produced for the Olympics basically are a giveaway, says Tom Doyle, vice president of information and research at the National Sporting Goods Association in Mount Prospect, Ill. He adds that recognition of the item helps in sales of consumer versions later. The association figures retail sales of sporting goods <a href=http://www.vtbuilder.com>www.vtbuilder.com</a> will rise 2 percent in 2004 to $46.6 billion.
Only a small fraction of that is swimsuits and other gear for worldclass athletes, he adds. Pole Vault: At the 1896 Olympics in Athens, a bamboo pole was used to set the vaulting record of 10 feet, 6 inches. Between 1942 and 1957, aluminum, steel, and fiberglass poles were tried. Fiberglass won out, increasing the indoor world record height to 20 feet, 2 inches in 1993.
Sprint: Wooden starting blocks replaced toe grooves at the 1948 London games. (In ancient Greece, runners took off from a standing position and were flogged if they started too soon.) Modern metal starting blocks contain microcontrollers to prevent false starts.
Marathon: Wedgeheeled Nike sneakers at 1972 US Olympic trials began the modern runningshoe era..
