Robert Lee "Bullet Bob" Hayes was an Olympic gold medalist sprinter who then became an American football wide receiver in the National Football League for the Dallas Cowboys. Bob Hayes is the only athlete to win both an Olympic gold medal and a Super Bowl ring. An American track and field athlete, he was a two-sport stand-out in college in both track and football at Florida A&M University. Hayes was enshrined in the Dallas Cowboys Ring of Honor in 2001 and was selected for induction in the Pro Football Hall of Fame in January 2009. Hayes is the second Olympic gold medalist to be inducted to the Pro Football Hall of Fame, after Jim Thorpe. He once held the world record for the 70-yard dash. He also is tied for the world's second-fastest time in the 60-yard dash. He was once considered the "world's fastest human" by virtue of his multiple world records in the 60-yard, 100-yard, 220-yard, and Olympic 100-meter dashes. He was inducted into the United States Olympic Hall of Fame.
Swimming has been a sport at every modern Summer Olympics. It has been open to women since 1912. Swimming has the second-highest number of Olympic medal contested events after athletics.
The 40-yard dash is a sprint covering 40 yards (36.58 m). It is primarily run to evaluate the speed and acceleration of American football players by scouts, particularly for the NFL Draft but also for collegiate recruiting. A player's recorded time can have a heavy impact on his prospects in college or professional football. This was traditionally only true for the "skill" positions such as running back, wide receiver, and defensive back, although now a fast 40-yard dash time is considered important for almost every position. The 40-yard dash is not an official race in track and field athletics, and is not an IAAF-recognized race.
The following table shows the world record progression in the men's 200 metres, as ratified by the IAAF. The current record of 19.19 seconds was set by Usain Bolt at the 2009 World Championships in Athletics.
The first world record in the 400 m for men (athletics) was recognized by the International Amateur Athletics Federation, now known as the International Association of Athletics Federations, in 1912. The IAAF ratified Charles Reidpath's 48.2 performance set at that year's Stockholm Olympics as a world record, but it also recognized the superior mark over 440 yards run by Maxie Long in 1900 as a world record.
The first World Record in the 200 m for women (athletics) was recognised by the Fédération Sportive Féminine Internationale (FSFI) in 1922. The FSFI was absorbed by the International Association of Athletics Federations in 1936. However, the IAAF did not maintain a record category for 200 m (bend) as opposed to 200 m (straight) until after 1951. The IAAF eliminated the 200 m (straight) record after 1976. "y" denotes times set at 220 yards which were ratified as world records.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water. Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.
Freestyle is a category of swimming competition, defined by the rules of the International Swimming Federation (FINA), in which competitors are subject to few limited restrictions on their swimming stroke. Freestyle races are the most common of all swimming competitions, with distances beginning with 50 meters and reaching 1500 meters, also known as the mile. The term 'freestyle stroke' is sometimes used as a synonym for 'front crawl', as front crawl is the fastest swimming stroke. It is now the most common stroke used in freestyle competitions.
The first world record in the men's 400 metres hurdles was recognised by the International Association of Athletics Federations in 1912. That inaugural record was the performance by Charles Bacon at the 1908 Olympics.
Ryan Murphy is an American competitive swimmer who specializes in backstroke. He is a 4-time Olympic gold medalist and the world-record holder in the men's 100-meter backstroke.
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.
This is a list of the NCAA outdoor champions in the short sprint event. Generally that was the 100-yard dash until 1975, with the metric 100 meters being contested in Olympic years starting in 1932. Metrication occurred in 1976, so all subsequent championships were at the metric distance. Hand timing was used until 1973, starting in 1974 fully automatic timing was used.
Caeleb Remel DresselOLY is an American swimmer who specializes in the freestyle and butterfly sprint events. He currently represents the Cali Condors which is part of the International Swimming League.

This is a list of the NCAA indoor champions in a long sprint event or short middle distance depending on the source's opinion. Generally that was the 600 yard run until 1983, and the 500 meters being contested 1984-87. The 1986 and 1987 races are reported to be on a short track. While both races, won by Roddie Haley are more than a second faster than two previous races, it is unclear if that is because the race was short or the track was less than 200 meters. Hand timing was used until 1975 and in 1980, starting in 1976 fully automatic timing was used.
This is a list of the NCAA indoor champions in a now defunct middle distance event. Generally that was the 1000 yard run until 1983, and the 1000 meters being contested 1984–87.
