More Info:

The 100 metres, or 100-metre dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, it is one of the most popular and prestigious events in the sport of athletics. It has been contested at the Summer Olympics since 1896 for men and 1928 for women.

The reigning 100 m Olympic champion is often named "the fastest man/woman in the world". Jamaicans Usain Bolt and Shelly-Ann Fraser-Pryce are the reigning world and Olympic champions in the men's and women's 100 metres, respectively.

Athletics Running Sports

Sprints are short running events in athletics and track and field. Races over short distances are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, which was a race from one end of the stadium to the other. There are three sprinting events which are currently held at the Summer Olympics and outdoor World Championships: the 100 metres, 200 metres, and 400 metres. These events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100 yard dash, the 200 m distances came from the furlong (or 1/8 of a mile), and the 400 m was the successor to the 440 yard dash or quarter-mile race.

At the professional level, sprinters begin the race by assuming a crouching position in the starting blocks before leaning forward and gradually moving into an upright position as the race progresses and momentum is gained. The set position differs depending on the start. Body alignment is of key importance in producing the optimal amount of force. Ideally the athlete should begin in a 4-point stance and push off using both legs for maximum force production. Athletes remain in the same lane on the running track throughout all sprinting events, with the sole exception of the 400 m indoors. Races up to 100 m are largely focused upon acceleration to an athlete's maximum speed. All sprints beyond this distance increasingly incorporate an element of endurance. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the accumulation of lactic acid in muscles.

Usain St. Leo Bolt OJ CD (/ˈjuːsn/; born 21 August 1986) is a Jamaican sprinter widely regarded as the fastest person ever. He is the first man to hold both the 100 metres and 200 metres world records since fully automatic time measurements became mandatory in 1977. Along with his teammates, he also set the world record in the 4×100 metres relay. He is the reigning Olympic champion in these three events, the first man to win six Olympic gold medals in sprinting, and an eight-time World champion. He was the first to achieve a "double double" by winning 100 m and 200 m titles at consecutive Olympics (2008 and 2012), and topped this through the first "double triple" (including 4×100 m relays).

The reigning 100 m Olympic champion is often named "the fastest man/woman in the world". Jamaicans Usain Bolt and Shelly-Ann Fraser-Pryce are the reigning world and Olympic champions in the men's and women's 100 metres, respectively.

The first record in the 100 metres for men (athletics) was recognised by the International Amateur Athletics Federation, now known as the International Association of Athletics Federations, in 1912. The record now is 9.58 seconds which was run by Usain Bolt.

As of 21 June 2011 (2011-06-21)[update], the IAAF had ratified 67 records in the event, not including rescinded records.

100 m: 09.69 s
200 m: 19.58 s

Tyson Gay (born August 9, 1982) is an American track and field sprinter, who competes in the 100 and 200 meters dash. His 100 m personal best of 9.69 seconds is the American record and makes him tied for second fastest athlete ever with Yohan Blake, and after Usain Bolt. His 200 m time of 19.58 makes him the fifth fastest athlete in that event. He holds the world record in the 200 meters straight.

Pablo S. McNeil (September 12, 1939 – July 4, 2011) was a Jamaican sprint athlete and sprinting coach. He participated in the 1964 Summer Olympics and the 1968 Summer Olympics. McNeil reached the semifinal of the 100 metres in the 1964 Olympics, finishing sixth with a wind assisted run of 10.30 seconds. He also ran as the first leg in the Jamaican 4x100 metres sprint relay team, placing fourth in the final with a time of 39.4 seconds. At his final Olympics in 1968, McNeil competed in the 100 metres once again but failed to pass the first round. His 100 metres personal best is a run of 10.54 seconds set in 1964.

Among his other sprinting achievements were a number of medals from the British West Indies Championships. He took the 200 m silver at the 1964 Championships, but his greatest haul came at the following year's event, where he finished just behind Lennox Miller for the 100 m silver medal and beat Clifton Bertrand, a two-time champion, to the 200 m gold with a run of 20.8 seconds. He represented Jamaica at the 1966 British Empire and Commonwealth Games in Kingston, Jamaica. He was part of the Jamaican 4×110 yards relay which won the silver medal and he reached the quarter-finals of both the 100 yard dash and 220 yard dash.
