Athletes are constantly looking to advances in technology to gain a competitive advantage,to jump just a bit higher,to hit a ball just a bit farther,and to return a serve just a bit quicker.But some-times a technical innovation comes along that temporarily breaks a sport.Thanks to adaptive suspension and computer-aided steering developed in the 1980s,Formula One racing cars became incredi-bly fast,but also so dangerous that the sport's governing body banned the technology in 1994.In 2008 and 2009,swimmers wearing the now-barred LZR Racer swimsuit line from the swim-wear company Speedo shattered 130 of the 134 world records for competitive swimming.
