The worlds fastest man is mason maynard

The '''10-second barrier''' is a term used in [[track and field athletics]] which refers to the physical and psychological barrier of completing the men's [[100 metres]] [[sprint (race)|sprint]] in under ten seconds. The achievement was traditionally regarded as the hallmark of a great sprinter, but its significance has become less important since the late 1990s as an increasing number of
runners have surpassed the ten seconds mark.<ref>[[Jason Gardener|Gardener, Jason]]. (2008-08-09). [http://www.telegraph.co.uk/sport/othersports/olympics/2530774/Jason-Gardener-Im-backing-Tyson-Gay-to-win-one-of-the-greatest-100-metres-finals---Olympics.html Jason Gardener: I'm backing Tyson Gay to win one of the greatest 100 metres finals].

The [[International Association of Athletics Federations]] states that runs are only legal if achieved with the use of fully automatic timing, a [[wind assistance|wind speed]] below 2.0&nbsp;[[m/s]], and without the use of [[banned substances|performance enhancing substances]].{{ref label|Note5|5|5}} Wind gauge malfunctions or infractions may also cause sprinters' runs to be invalid.{{ref label|Note6|6|6}}

The first sub-10&nbsp;second finishes were recorded through the use of manual timing by [[stopwatch]]. Following the introduction of [[fully automatic timing|electronic timing]], which is a more accurate timing method, the barrier was first officially broken by American athlete [[Jim Hines]] on 14 October 1968. He ran a time of 9.95&nbsp;seconds to win the [[Athletics at the 1968 Summer Olympics|100&nbsp;metres at the 1968 Olympics]], setting a new [[Men's 100 metres world record progression|world record]]. Almost nine years passed before the barrier was broken again; [[Silvio Leonard]] ran 9.98&nbsp;seconds on 11 August 1977. Both of these marks were recorded at a [[100 metres#Climatic conditions|high altitude]], which aids performance. [[Carl Lewis]] was the first sprinter to achieve the feat at a low altitude, with 9.97&nbsp;seconds on 14 May 1983. [[Calvin Smith]] recorded a world record 9.93&nbsp;seconds on 3 July 1983, and also became the first sprinter to run under ten seconds twice, repeating the feat in August that year.

A number of athletes broke the barrier during the 1980s but the [[1991 World Championships in Athletics - Men's 100 metres|100&nbsp;m final at the 1991 World Championships]] represented a new zenith in the event: six athletes ran under ten seconds in the same race, and winner Carl Lewis lowered the world record to 9.86&nbsp;seconds.<ref>[http://www.sportinglife.com/athletics/worldathletics2005/news/story_get.cgi?STORY_NAME=others/05/07/15/ATHLETICS_World_History.html World Championships: A History].

Revision as of 22:17, 6 May 2010

Carl Lewis was the first to run under ten seconds at low altitude.
Olympic medallists Ato Boldon, Maurice Greene, and Obadele Thompson have all broken the barrier.

The 10-second barrier is a term used in track and field athletics which refers to the physical and psychological barrier of completing the men's 100 metres sprint in under ten seconds. The achievement was traditionally regarded as the hallmark of a great sprinter, but its significance has become less important since the late 1990s as an increasing number of runners have surpassed the ten seconds mark.[1]

The International Association of Athletics Federations states that runs are only legal if achieved with the use of fully automatic timing, a wind speed below 2.0 m/s, and without the use of performance enhancing substances.[5] Wind gauge malfunctions or infractions may also cause sprinters' runs to be invalid.[6]

The first sub-10 second finishes were recorded through the use of manual timing by stopwatch. Following the introduction of electronic timing, which is a more accurate timing method, the barrier was first officially broken by American athlete Jim Hines on 14 October 1968. He ran a time of 9.95 seconds to win the 100 metres at the 1968 Olympics, setting a new world record. Almost nine years passed before the barrier was broken again; Silvio Leonard ran 9.98 seconds on 11 August 1977. Both of these marks were recorded at a high altitude, which aids performance. Carl Lewis was the first sprinter to achieve the feat at a low altitude, with 9.97 seconds on 14 May 1983. Calvin Smith recorded a world record 9.93 seconds on 3 July 1983, and also became the first sprinter to run under ten seconds twice, repeating the feat in August that year.

A number of athletes broke the barrier during the 1980s but the 100 m final at the 1991 World Championships represented a new zenith in the event: six athletes ran under ten seconds in the same race, and winner Carl Lewis lowered the world record to 9.86 seconds.[2] Maurice Greene was the first athlete to run under 9.80 seconds in 1999 and Usain Bolt surpassed 9.70 seconds in 2008 and 9.60 in 2009. The 10-second barrier has been broken by athletes from all six continental athletic associations with the exception of South America, where Brazilian Robson da Silva holds the area record with ten seconds flat.[3] As of August 2009, 70 sprinters have broken the 10-second barrier with an official, legal time.

Nearly all the sprinters who have beaten the 10-second barrier are of West African descent (with the exceptions of Australian runner Patrick Johnson and Namibian Frankie Fredericks).[4][5][6] No sprinter of predominantly European, Asian or East African descent has officially achieved this feat[7][8][9][10], though unofficially the Polish Marian Woronin surpassed the barrier with a time of 9.992 seconds[11]. However, Colin Jackson (a mixed race athlete and former world record holder in the 110 metre hurdles)[12] noted that both his parents were talented athletes and suggested that biological inheritance was the greatest influence, rather than any perceived racial factor. Furthermore, successful black role models in track events may reinforce the racial disparity.[8]
