Olympic records have been falling steadily for more than a century, largely because of improvements in physical fitness and training.The London Games, however, are putting a new focus on another factor pushing Olympic achievement to new heights: better technology.
Innovations in clothing get much of the attention at the Olympics.
From track suits to running shoes, new designs and re-engineered fabrics are aimed at making athletes faster. Compression garments are a big trend. Compression helps blood flow and keeps an area taut so there is less muscle pull and strain, said Mark Sunderland, a textile engineer at Philadelphia University and a performance-apparel expert.”The fabric itself is taking on some of the workload the muscles would have taken on,” he said One of the biggest attention grabbers so far: Nike’s full-body track suit made of recycled polyester and plastic bottles. On the arms and legs are raised dots, reminiscent of dimples on a golf ball, that are designed to reduce drag. The company claims the suit is 0.023 second faster in the 100-meter sprint than Nike’s previous suits. That may seem minuscule, but new world records in the 100 meters are often broken by tenths or hundredths of a second.On the shoe front, Nike is debuting a minimalist design, the Flyknit, a nearly seamless, meshlike shoe that is in keeping with the barefoot “less-is-more” approach to running. The 5.6-ounce weight is 19 percent lighter than the Nike shoes worn by marathoners in the men’s 2011 World Championships.Adidas is introducing a 3.5-ounce spiked sprinting shoe, adizero Prime SP. The idea behind the lightweight shoes, worn by U.S. sprinter Tyson Gay, is that lower mass allows runners to accelerate and change direction faster. Do changes work? Pole vault: Poles went from wood to bamboo and then to metal before switching to carbon or glass fiber; 27 percent of the 86 percent improvement in records was because of changes in materials.
