World Records In Athletics
World records in athletics are ratified by World Athletics. Athletics records comprise the best performances in the sports of track and field, road running and racewalking. Records are kept for all events contested at the Olympic Games and some others. Unofficial records for some other events are kept by track and field statisticians. The only non-metric track distance for which official records are kept is the mile run. Criteria The criteria which must be satisfied for ratification of a world record are defined by World Athletics in Part III of the Competition Rules. These criteria also apply to national or other restricted records and also to performances submitted as qualifying marks for eligibility to compete in major events such as the Olympic Games. The criteria include: * The dimensions of the track and equipment used must conform to standards. In road events, the course must be accurately measured, by a certified measurer. * Except in road events (road running and r ...

1 (one, unit, unity) is a number, Numeral (linguistics), numeral, and glyph. It is the first and smallest Positive number, positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit (measurement), unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In Digital electronics, digital technology, 1 represents the "on" state in binary code, the foundation of computing.

Drug Testing
A drug test (also often toxicology screen or tox screen) is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites. Major applications of drug testing include detection of the presence of performance enhancing steroids in sport, employers and parole/probation officers screening for drugs prohibited by law (such as cocaine, methamphetamine, and heroin) and police officers testing for the presence and concentration of alcohol (ethanol) in the blood commonly referred to as BAC (blood alcohol content). BAC tests are typically administered via a breathalyzer while urinalysis is used for the vast majority of drug testing in sports and the workplace. Numerous other methods with varying degrees of accuracy, sensitivity (detection threshold/cutoff), and detection periods exist. A drug test may also refer to a test that provides quantita ...

IAAF Golden League
The IAAF Golden League was an annual series of outdoor track and field meetings organised by the International Association of Athletics Federations (IAAF). Athletes who won specific events at all of the series meetings were awarded a jackpot prize, sometimes given in gold bars, which inspired the series name. The competition began with seven meetings and it lasted for twelve years as the IAAF's top tier of one-day meetings. Within the IAAF's global circuit, athletes received additional points for their performances at the Golden League for the IAAF Grand Prix (1998–2002), IAAF World Outdoor Meetings (2003–2005), then IAAF World Athletics Tour (2006–2009). The Golden League was replaced in 2010 by the Diamond League, which marked an expansion to fourteen seasonal meetings covering all track and field events except the hammer throw.The origins of the Golden League trace back to the Golden Four series that ran from 1993 to 1997, comprising four top level European meetings on ...

Diamond League
The Diamond League is an annual series of elite track and field athletic competitions comprising fifteen invitational athletics meetings. The series sits in the top tier of the World Athletics one-day meet competitions. The inaugural season was in 2010. It was designed to replace the IAAF Golden League, which had been held annually since 1998.

Sponsor (commercial)
Sponsoring something (or someone) is the act of supporting an event, activity, person, or organization financially or through the provision of products or services. The individual or group that provides the support, similar to a benefactor, is known as the sponsor. Definition Sponsorship is a cash and/or in-kind fee paid to a property (typically in sports, arts, entertainment or causes) in return for access to the exploitable commercial potential associated with that property. While the sponsee (property being sponsored) may be nonprofit, unlike philanthropy, sponsorship is done with the expectation of a commercial return. While sponsorship can deliver increased awareness, brand building and propensity to purchase, it is different from advertising. Unlike advertising, sponsorship can not communicate specific product attributes. Nor can it stand alone, as sponsorship requires support elements. Proponents of sponsorship would, however, point to its unique position in the marketi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Of High Altitude On Humans
The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The medical problems that are direct consequence of high altitude are caused by the low inspired partial pressure of oxygen, which is caused by the reduced atmospheric pressure, and the constant gas fraction of oxygen in atmospheric air over the range in which humans can survive. The other major effect of altitude is due to lower ambient temperature. The Oxygen saturation (medicine), oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. However, the human body has both short-term and high-altitude adaptation in humans, long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above as the death zone, where it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fully Automatic Timing
Fully automatic timing (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 s ...

Photo Finish
A photo finish occurs in a sporting race when multiple competitors cross the finishing line at nearly the same time. As the naked eye may not be able to determine which of the competitors crossed the line first, a photo or video taken at the finish line may be used for a more accurate check. Photo finishes make it less likely that officials will declare a race a dead heat (racing), dead heat. Finish line photos are still used in nearly every modern racing sport. Although some sports use electronic equipment to track the racers during a race, a photo is considered the most important evidence in selecting the winner. They are especially important during close races, but they are also used to assign official times to each competitor during any race. Method of capture Strip photography Photo-finish cameras were developed during the 1940s and 1950s as a means of regulating the racing industry and to reduce cheating. Betting on races became increasingly popular during the middle dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
