贡献一大批世界纪录打破世界纪录的多少,是衡量田径大赛水平高低的重要标志之一。在已经举行过的十届世锦赛上,除了第6、8两届没有世界纪录问世,其它八届均创造过新的世界纪录和世界最好成绩,累计改写世界纪录和世界最好成绩达到22次。1987年,在罗马举行的第2届世锦赛上,先后出现了两次打破世界纪录的场景——加拿大的本.约翰逊在男子100米决赛中跑出9秒83,超9秒93的世界纪录:保加利亚女将科斯塔基诺娃跳过2米09横杆,破跳高世界纪录。不过事后,本.约翰逊因服用兴奋剂东窗事发,金牌被国际田联收回。 Contribution of a large number of world records Breaking the number of world records, is one of the important indicators of the level of track and field competitions. In the 10th World Championships that have been held, except for the 6th and 8th editions, there are no world records available. The other 8th have all created new world records and best results in the world. They have rewritten the world record and the world record of 22 Times. In 1987, at the 2nd World Championships in Rome, there were two scenes of breaking the world record - Ben Johnson of Canada ran 9 seconds 83, 9 seconds 93 world records in the men’s 100 meters final : Bulgaria women Costantino Nova skip the 2-meter 09 crossbar, breaking world records. However, afterwards, Ben Johnson for doping, the gold medal was recalled by the IAAF.
