NM in track and field rules, WR in sports is the world record, then what is WL??

In track and field competitions, we often hear two abbreviations NM and WR. Among them, NM stands for "invalid long jump," which refers to violations committed by a player in his long jump attempt during a competition, such as stepping on the line or leaving the ground prematurely. Such attempts will not be counted into the competition result. Correspondingly, WR represents the "world record", which means that the player has created the best result in the world in this event. So, what does WL represent?

WL stands for "World Leading", which refers to the highest annual score in events such as track, field and track events. In other words, whether in domestic or international competitions, only if you achieve the highest score in the event can you be called the best score of the year. WL is an important title, which means that the player achieved the best results in the world in designated events during the year. Winning WL is a kind of recognition and affirmation for players, and it is also one of their goals.

The calculation of WL is the responsibility of the International Athletic Federation (IAAF). They collect and verify the top scores in each event around the world, and then publish them to track and field enthusiasts around the world. These results are often used as a reference for player selection, pre-match seed ranking and ranking, and competition schedule arrangements. Therefore, the location of WL is also very important to track and field teams and athletes from various countries.

WL is also related to the time of the season. Each event will have a certain season time, and the results achieved during this time period will be included in the calculation. Once the season is over and the new year begins again, the previous WL will be reset. Therefore, the WL for each season is calculated independently, and players must continue to work hard to achieve the best results again in the new year.

WL represents the best result of the year in track and field competitions and is the goal pursued by athletes in various events. By achieving WL, players can gain international recognition and respect, and can also win honors for their country. Its calculation and release are the responsibility of the International Association of Athletics Federations, and the WL for each season is calculated independently. Only the player with the highest score can be called the best of the year, so WL is also one of the driving forces for the players to strive.
