A They play hard, they play often, and they play to win. Australian sports teams win more than their fair share of titles, demolishing rivals with eming ea. How do they do it? A big part of the cret is an extensive and expensive network of sporting academies underpinned by science and medicine. At the Australian Institute of Sport (AIS), hundreds of youngsters and pros live and train under the eyes of coaches. Another body, the Australian Sports Commission (ASC), finances programmes of excellence in a total of 96 sports for thousands of sportsmen and women. Both provide intensive coaching, training facilities and nutritional advice.
B Inside the academies, science takes centre stage. The AIS employs more than 100 sports scientists and doctors, and collaborates with scores of others in universities and rearch centres. AIS scientists work across a number of sports, applying skills learned in o
ne - such as building muscle strength in golfers - to others, such as swimming and squash. They are backed up by technicians who design instruments to collect data from athletes. They all focus on one aim: winning. ‘We can't waste our time looking at ethereal scientific questions that don't help the coach work with an athlete and improve performance,' says Peter Fricker, chief of science at AIS.
C A lot of their work comes down to measurement - everything from the exact angle of a swimmer’s dive to the cond-by-cond power output of a cyclist. This data is ud to wring improvements out of athletes. The focus is on individuals, tweaking performances to squeeze an extra hundredth of a cond here, an extra millimetre there. No gain is too slight to bother with. It’s the tiny, gradual improvements that add up to world-beating results. To demonstrate how the system works, Bruce Mason at AIS shows off the prototype of a 3D analysis tool for studying swimmers. A wire-frame model of a champion swimmer slices through the water, her arms moving in slow motion. Looking side-on, Mason measures the distance between strokes. From above, he analys how her spine swivels. When fully developed, this system will enable him to build a biomechanical profil
e for coaches to u to help budding swimmers. Mason's contribution to sport also includes the development of the SWAN (SWimming ANalysis)system now ud in Australian national competitions. It collects images from digital cameras running at 50 frames a cond and breaks down each part of a swimmer's performance into factors that can be analyd individually - stroke length, stroke frequency, average duration of each stroke, velocity, start, lap and finish times, and so on. At the end of each race, SWAN spits out data on each swimmer
记忆单词D ‘Take a look,' says Mason, pulling out a sheet of data. He points out the data on the swimmers in cond and third place, which shows that the one who finished third actually swam faster. So why did he finish 35 hundredths of a cond down? ‘His turn times were 44 hundredths of a cond behind the other guy,' says Mason. ‘If he can improve on his turns, he can do much better’ This is the kind of accuracy that AIS scientists' rearch is bringing to a range of sports.

oping unobtrusive nsors that will be embedded in an athlete's clothes or running shoes to monitor heart rate, sweating, heat production or any other factor that might have an impact on an athlete's ability to run. There's more to it than simply measuring performance. Fricker gives the example of athletes who may be down with coughs and colds 11 or 12 times a year. After years of experimentation, AlS and the University of Newcastle in New South Wales developed a test that measures how much of the immune-system protein immunoglobulin A is prent in athletes' saliva. If IgA levels suddenly fall below a certain level, training is ead or dropped altogether. Soon, IgA levels start rising again, and the danger pass. Since the tests were introduced, AIS athletes in all sports have been remarkably successful at staying healthy.自制卤水豆腐
E Using data is a complex business. Well before a championship, sports scientists and coaches start to prepare the athlete by developing a ‘competition model', bad 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 the times.' All the training is then

F Of cour, there's nothing to stop other countries copying-and many have tried. Some years ago, the AIS unveiled coolant-lined jackets for endurance athletes. At the Atlanta Olympic Games in 1996, the sliced as much as two per cent off cyclists' and rowers' times. Now everyone us them. The same has happened to the ‘altitude tent', developed by AIS to replicate the effect of altitude training at a level. But Australia's success story is about more than easily copied technological fixes, and up to now no nation has replicated its all-encompassing system.
