Using data is a complex business. Well before a championship, sports scientists

问题 Using data is a complex business. Well before a championship, sports scientists and coaches start to prepare the athlete by developing a ’competition model’, based on what they expect will be the winning times. ’You design the model to make that time,’ says Mason. ’A start of this much, each free-swimming period has to be this fast, with a certain stroke frequency and stroke length, with turns done in these times.’ All the training is then geared towards making the athlete hit those targets, both overall and for each segment of the race. Techniques like these have transformed Australia into arguably the world’s most successful sporting nation.
Of course, there’s nothing to stop other countries copying — and many have tried. Some years ago, the Australian Institute of Sport unveiled coolant-lined jackets for endurance athletes. At the Atlanta Olympic Games in 1996, these sliced as much as two per cent off cyclists’ and rowers’ times. Now everyone uses them.
