A major multisport event, the Summer Olympics take place every four years. In a variety of sports, the world's greatest athletes compete against each other, either individually or as a team.

Tokyo is hosting the 2020 Summer Olympic Games, despite the Fukushima nuclear plant disaster in 2013. Prior to Tokyo, Sapporo, and Nagano, the first Summer Olympic Games were held in 1964. Japan are hosting the Olympic Games for the fourth time in history.

Gymnastics, track and field, aquatics, boxing, boxing, archery, soccer, handball, basketball, tennis, and many other sports are typically featured during the Summer Olympics in London. In one era or another, there were 42 sports in the Olympics. From July 23 to August 8, 2021, the Tokyo 2020 Games are scheduled.

What do OR and WR mean in the Olympics?

Many of the sports that fall under the athletic category, such as track and field, rely on statistics. Numerous acronyms have become widespread in the sport as a result of the need to convey this information effectively. Bert Nelson and Cordner Nelson began Track & Field News in 1948, and the publication quickly became the industry leader in inventing and defining acronyms.

Apart from World Athletics, other governing organizations and media outlets have also adopted these abbreviations: the Association of Track and Field Statisticians, the Association of Road Racing Statisticians, The Associated Press as well as the individual media outlets that receive their reports.

Most records must be ratified by the record's governing organization before they can be made public. The IAAF is the international governing body for athletics. The OR abbreviation means "Olympic Record" and this record can only be made at the Olympic Games. Meanwhile, the WR abbreviation stands for "World Record" and world records can be made at the Olympics, as well as at any other athletic competition.
