The Nasa swimsuit that rocked the 2008 Olympics

Available for over a year

Imagine creating a swimsuit so good it would have to be banned. That's what Jason Rance and his team at Speedo did ahead of the Beijing Olympic Games in August 2008. Wearing the LZR Racer swimsuit, United States swimmer Michael Phelps won a record eight gold medals at the Water Cube. Athletes wearing the swimsuit would shatter 30 world records in the space of three months. The reduction in skin friction drag was so significant, some called it "technological doping". The suit developed with space agency Nasa had no seams, featured a special water-repellent fabric and had a design covering the legs which lifted the swimmer's hips in the water. It caused a furore with athletes ditching sponsorship agreements with rival firms to get hold of it. A slew of copycats came on the market before the design was banned from future competitions. Jason Rance who was the head of Speedo's research and development Aqualab, reveals to Josephine McDermott the behind-the-scenes development which would turn competitive swimming on its head.
