The Science of Sport
1 At the 2004 Olympic Ga mes 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 alimit to human performance or will athletes continue to gain seconds？
3 Most experts a gree that it isn't the athletes' bodies which ha ve changed but the huge advances in sport science which ha ve enabled them to improve their performances. The individual athlete obviously has to ha ve the necessary skill and determination to succeed, but the help of science and technology can be significant. Research has brought abetter understanding of the athlete's body and mind but the advances in sports equipment technology ha ve also had an important impact on human performance.
4 Scientists ha ve 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 progra mme anti diet better to their particular needs. Running the marathon and cycling, for exa mple, are endurance (耐力) sports and require adifferent parathion (硝苯硫磷脂) to that of a 100-metre sprinter. In some sports, changes in techniques ha ve significantly !reproved performance.
5 But in any sport, aplayer's success or failure results from Acombination of both physical and mental abilities. Most coaches use psychological techniques to help their athletes cope with stress and concentrate on their performance. For exa mple, the English football tea m listens to music in the changing rooms before a ga me to help the players rela x and not feel so nervous. Before Adifficult match, tennis players are encoura ged 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 head of the competition, the sporting challenge？ What's more, are all these advanta ges fair？
