19 12, men's 4x 100 and 4x400 relay races are officially listed as Olympic events.
1928, the women's 4x 100 relay officially became an Olympic event.
The men's 4x 100 relay was first listed as an Olympic event in 19 12. A total of eight teams participated in the competition, but in the end only two teams were selected, and the United States and Sweden won the championship and runner-up respectively. Germany set the first official world record of the event in 42.3 seconds in the preliminaries. Since then, the United States has made a splash in the Olympic relay race. From the 7th Olympic Games on 192, except for 1960, 1988,1992 (I didn't participate in the Moscow Olympic Games on the afternoon of1980), I won all the other 4x 100-meter relays. They also made contributions to the World Cup and World Championships. Although the competition for world records is fierce, most of the time is in the hands of Americans, and Britain, the Netherlands and Germany are also in the lead.
The 4x400-meter relay was included in the Olympic Games four years earlier than the 4x 100-meter relay, and the American team made a brilliant record. In the decades since the United States 19 1 1 set the first world record, although the world record has been refreshed many times, most of it was created by the American team.
The women's relay race entered the world stage late. 1928 Olympic Games held the women's 4x 100 relay race for the first time, and Canada won the championship in 48.4 seconds. Four years later, the United States won the trophy in 47 seconds. 1936 Berlin Olympic Games, the Germans set the first world record in 46.4 seconds in the preliminary round, but the champion was taken away by the Americans. 1952 Olympic Games, 4x 100 meters relay race climaxes one after another. First, Australia broke the world record in the preliminaries, and then the United States and the former Federal Republic of Germany broke the record in the final, tying the championship and runner-up. In the 1960s, the former Soviet Union also showed some strength and broke the world record several times. The women's 4x400 relay started late, and the former Soviet Union set the first world record with 1969, with a score of 3 minutes and 47.4 seconds. But this is just the beginning. This year, this record is flooding in. In less than four months, the former Soviet Union, Britain, France, Germany and other countries in Europe competed in the same field, breaking the world record seven times, and their scores increased from 3 minutes 47.4 seconds to 3 minutes 30.8 seconds. 1972, women's 4x400 relay.
