The modern Olympic Games were founded with the intention of improving health and education, promoting world peace, and encouraging fair and equal competition. But over the years, the Olympic saying, "faster, higher, per", has pushed scientists as well as athletes to do everything possible to reach new levels.
Doctors, engineers and coaches all use everything science has to offer to achieve that little bit extra in competition. The reason modern technology has become part of sport is very simple: winning is just as important as it was 2,500 years ago at the Olympics of ancient Greece.
Developments in technology have often been reflected in the methods of training and performance used at the Olympics through history. This technology falls into two main groups: improving an athlete’s performance in competition, and allowing results to be measured more accurately.
The introduction of high-tech equipment means that athletes in all sports, from the 100-metres sprint to the pole vault, can now train more effectively and nourish their bodies better.
