4 × 100 Metres Relay
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. Each runner carries a relay baton. Before 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017, that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, and the incoming runner cannot touch it after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colours and style are only "recommended". While most legacy tracks will still have the older markings, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics (sport), athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete. Like other sprint disciplines, the 400 m involves the use of starting blocks. The runners take up position in the blocks on the 'ready' command, adopt a more efficient starting posture which Isometric exercise#Isometric presses as preparation for explosive power movements, isometrically preloads their muscles on the 'set' command, and stride forwards from the block ...

Fully Automatic Timing
Fully automatic time (abbreviated FAT) is a form of race timing in which the clock is automatically activated by the starting device, and the finish time is either automatically recorded, or timed by analysis of a photo finish. The system is commonly used in track and field as well as athletic performance testing, horse racing, dog racing, bicycle racing, rowing and auto racing. In these fields a photo finish is used. It is also used in competitive swimming, for which the swimmers themselves record a finish time by touching a touchpad at the end of a race. In order to verify the equipment, or in case of failure, a backup system (typically manual) is usually used in addition to FAT. Technology In races started by a starting pistol, a sensor is typically attached to the gun which sends an electronic signal to the timing system when fired. An alternative starting light or sound which is electronically triggered, such as a horn, is typically also wired to the timing system. In sports ...

Jamaica
Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of Hispaniola (the island containing the countries of Haiti and the Dominican Republic); the British Overseas Territory of the Cayman Islands lies some to the north-west. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. The island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it ''Jamaica''. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their des ...

Anchor Leg
The anchor leg is the final position in a relay race. Typically, the anchor leg of a relay is given to the fastest or most experienced competitor on a team. The athlete completing the anchor leg of a relay is responsible for making up ground on the race-leader or preserving the lead already secured by their teammates. Notable track examples "Bullet" Bob Hayes ran anchor leg for the United States 4 × 100 metres relay team in the 1964 Tokyo Olympics. Receiving the baton in fifth place, Hayes pulled ahead of four runners to win the race. A French rival, Jocelyn Delecour, remarked to the American lead-off runner Paul Drayton (athlete), Paul Drayton "You haven't got anything except Hayes", and Drayton responded "That's all we need, pal." Carl Lewis never lost a race when he anchored the American 4 × 100 m relay team. He regularly ran under 9 seconds for his anchor legs and helped the team break the Men's 4 × 100 metres relay world record progression, world record in the 4 × 100 m r ...
