The Science of Sport 1 At the 2004
Olympic Games in Athens, the Chinese athlete Liu Xiang equaled the world record
for the 110 metres hurdles (跨栏) when he ran the race in 12.91 seconds. This
record time had been set in 1993 by British sprinter (短跑运动员) Colin Jackson and 9
years went by before another athlete was able to run as fast. 2
Record-breaking in all track events is slowing down and we appear to be
moving much closer to the limits of human performance. Nevertheless, every four
years, records which were previously thought to be unbeatable are broken. So
what’s behind this never-ending improvement in performance And how long can we
keep breaking records Is there a limit to human performance or will athletes
continue to gain seconds 3 Most experts agree that it isn’t the
athletes’ bodies which have changed but the huge advances in sport science which
have enabled them to improve their performances. The individual athlete
obviously has to have the necessary skill and determination to succeed, but the
help of science and technology can be significant. Research has brought a better
understanding of the athlete’s body and mind but the advances in sports
equipment technology have also had an important impact on human
performance. 4 Scientists have shown that an athlete’s body’s needs
vary according to the type of sport. This research has helped top sports people
to adapt their training programme and diet better to their particular needs.
Running the marathon and cycling, for example, are endurance (耐力) sports and
require a different parathion (硝苯硫磷脂) to that of a 100-metre sprinter. In some
sports, changes in techniques have significantly improved performance. 5
But in any sport, a player’s success or failure results from a combination
of both physical and mental abilities. Most coaches use psychological techniques
to help their athletes cope with stress and concentrate on their performance.
For example, the English football team listens to music in the changing rooms
before a game to help the players relax and not feel so nervous. Before a
difficult match, tennis players are encouraged to use visualization (想象)
techniques to build confidence and this is almost as good as practice. 6
But as science begins to dominate sport, are we in danger of losing sight
of the heart of the competition, the sporting challenge What’s more, are all
these advantages fair Paragraph 2 ______.
A Different sports require different training programs.
B Science may be too important today.
C Sports equipment has been improved a lot.
D Athletes are still breaking records.
E Sport science helps improve athletes’ performances.
F Mental training is as important as physical training.
