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', 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.
F Of course, 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,
these sliced as much as two percent off cyclists' and rowers' times.
Now everyone uses them. The same has happened to the 'altitude tent',
developed by AIS to replicate the effect of altitude training at sea 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.
Answer the questions below.
Choose NO MORE THAN THREE WORDS AND/OR A NUMBER from the passage for each
answer.
1. What is produced to help an athlete plan their performance in an event?
2. By how much did some cyclists' performance improve at the 1996
Olympic Games?
