Oregon Track and Field World Championships: McPlain's fourth time in 13 months refresh the world record

[Global Times Comprehensive Report] Breaking the world record is not the norm of today's track and field. In the third match day of the Solidar by the Wheels, the 22 -year -old Tokyo Olympic Champion McPlain won the women's 400 -meter column project in 50 seconds 68. This is the fourth time McPlain refreshed the world record in 13 months -since June 2021, she has updated the world record from 52 seconds 16 to 50 seconds 68. Those who can break the world record four times in the 400 -meter column project (male/female) dates back to the American men's track and field player Edwin Moses more than forty years ago.

At the women's 200 -meter project of this track and field World Championships, Jackson Jackson's winning results will break the World Championship record at 21 seconds 45, but it cannot shake the 21 seconds 34 world record that American player Jona ran at the 1988 Olympic Games. In addition, Jona ran 10 seconds 49 on the 100 -meter project of the Olympic Games in the 1988 Olympic Games. This world record has not been able to break.

"In the Jona era, the drug testing is not systematic." The British "Guardian" summarized on the 23rd that since the 1980s, many world records in women's track and field projects have not been broken, including 400 meters, including 400 meters, including 400 meters, including 400 meters, including 400 meters, including 400 meters, including 400 meters, including 400 meters, including 400 meters, including 400 meters, 800 meters, high jump, long jump, iron cake and shot shot.国际田联主席塞巴斯蒂安·科称：“从法律上讲，这些成绩的确是世界纪录。但由于当时药物检测工作的不系统，这些纪录可能并不可靠。”在他看来，虽然It is difficult for the current players to break the long -lost world records, but the appearance of super running shoes and fast runways may break this deadlock in the future.

In addition to banning drug factors, human physical limit also restricts the improvement of track and field results, especially short -range sprint projects. However, the men's marathon project is still steadily shortened. The current world record of the project is 2 hours, 1 minute and 39 seconds. Running for 2 hours is the long -term goal of this project. Angus, an associate professor of Monacon University of Melbourne, believes that breaking through two hours requires continuous improvement and accumulation in the fields of technology, physiology, psychology, and nutrition. In this World Championships, Ethiopian player Tol won the men's marathon championship in 2 hours, 5 minutes and 36 seconds and broke the record.

At the men's 4 × 100m relay final ended on the 24th of Beijing time, the Canadian team won the championship. The U.S. team won the women's relay champion. (Li Jiayin)
