The sports under the umbrella of athletics, particularly track and field, use a variety of statistics. In order to report that information efficiently, numerous abbreviations have grown to be common in the sport. Starting in 1948 by Bert Nelson and Cordner Nelson, Track & Field News became the leader in creating and defining abbreviations in this field. These abbreviations have also been adopted by, among others, World Athletics; the world governing body, various domestic governing bodies, the Association of Track and Field Statisticians, the Association of Road Racing Statisticians, the Associated Press, and the individual media outlets who receive their reports. These abbreviations also appear in Wikipedia.
