Sprint (running)
Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. In athletics (sport), athletics and track and field, sprints (or dashes) are races over short distances. They are among the oldest running competitions, being recorded at the Ancient Olympic Games. Three sprints are currently held at the modern Summer Olympics and outdoor IAAF World Championships in Athletics, World Championships: the 100 metres, 200 metres, and 400 metres. At the professional level, sprinters begin the race by assuming a crouching position in the starting bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Usain Bolt 2012 Olympics 1
Usain St. Leo Bolt (; born 21 August 1986) is a Jamaican retired sprinter who is widely regarded as the greatest sprinter of all time. He is an eight-time Olympic gold medalist and the world record holder in the 100 metres, 200 metres, and 4 × 100 metres relay. Bolt is the only sprinter to win Olympic 100 m and 200 m titles at three consecutive Olympics (2008, 2012, and 2016). He also won two 4 × 100 relay gold medals. He gained worldwide fame for his double sprint victory in world record times at the 2008 Beijing Olympics, which made him the first person to hold both records since fully automatic time became mandatory. An eleven-time World Champion, he won consecutive World Championship 100 m, 200 m and 4 × 100 metres relay gold medals from 2009 to 2015, with the exception of a 100 m false start in 2011. He is the most successful male athlete of the World Championships. Bolt is the first athlete to win four World Championship titles in ...

Isometric Exercise
An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words ''isos'' (equal) and ''-metria'' (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied. This is in contrast to ''isotonic contractions'', in which the contraction strength does not change, though the muscle length and joint angle do. The three main types of isometric exercise are isometric presses, pulls, and holds. They may be included in a strength training regime in order to improve the body's ability to apply power from a static position or, in the case of isometric holds, improve the body's ability to maintain a position for a period of time. Considered as an action, isometric presses are also of fundamental importance to the body's ability to prepare itself to perform immediately subsequent pow ...

440-yard Dash
The 440-yard dash, or quarter-mile race, is a sprint race in track and field competitions. In many countries, athletes compete in the 440 yard The yard (symbol: yd) is an English units, English unit of length in both the British imperial units, imperial and US United States customary units, customary systems of measurement equalling 3 foot (unit), feet or 36 inches. Sinc ... dash (402.336 m) – which corresponds to a quarter mile. Many athletic tracks are 440 yards per lap. In the 19th century it was thought of as a middle distance race. History World-record holder Lon Meyers (1858–1899) was the first person to run the 440 in under 50 seconds. In 1947, Herb McKenley of Jamaica set a world record in the event with a time of 46.3 seconds, which he lowered the following year to a new world record of 46.0 seconds. Adolph Plummer took the record under 45 seconds with a 44.9 on May 25, 1963. In 1971, John Smith lowered the world record to 44.5 sec ...

Mile
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a imperial unit, British imperial unit and United States customary unit of length; both are based on the older English unit of Unit of length, length equal to 5,280 Foot (unit), English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international yard and pound, international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the #Roman, Roman mile (roughly ), such as the #Nautical, nautical mile (now exactly), the #Italian, Italian mile (roughly ), and the li (unit), Chinese mile (now exactly). The Romans divided their mile into 5,000 (), but the greater importance of furlongs in the Kingdom of England#Tudor period, Elizabethan-era England meant th ...

Furlong
A furlong is a measure of distance in imperial units and United States customary units equal to one-eighth of a mile, equivalent to any of 660 foot (unit), feet, 220 yards, 40 rod (unit), rods, 10 chain (unit), chains, or approximately 201 metres. It is now mostly confined to use in horse racing, where in many countries it is the standard measurement of race lengths, and agriculture, where it is used to measure rural field lengths and distances. In the United States, some states use older definitions for surveying purposes, leading to variations in the length of the furlong of two parts per million, or about . This variation is small enough to not have practical consequences in most applications. Using the International yard and pound, international definition of the yard as exactly 0.9144 metres, one furlong is 201.168 metres, and five furlongs are about 1 kilometre ( exactly).

100-yard Dash
The 100-yard dash is a track and field sprint event of . It was part of the Commonwealth Games until 1970, and was included in the triathlon of the Olympics in 1904. It is not generally used in international events, replaced by the 100-metre sprint (109.36 yards). However, it is still occasionally run in the United States in certain competitions; in the NCAA championships it was last run in 1975. Walter Halben Butler (1852–1931) is credited with being the first to run the race in 10 seconds.

Imperial Measurement
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the related but differing system of customary units of the United States. The imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empire, notably Canada. The modern UK legislation defining the imperial system of units is given in the Weights and Measures A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1928 Summer Olympics
The 1928 Summer Olympics (), officially the Games of the IX Olympiad (), was an international multi-sport event that was celebrated from 28 July to 12 August 1928 in Amsterdam, Netherlands. The city of Amsterdam had previously bid for the 1920 and 1924 Olympic Games. Still, it was obliged to give way to war-torn Antwerp in Belgium for the 1920 Summer Olympics, 1920 Games and Pierre de Coubertin's Paris for the 1924 Summer Olympics, 1924 Games. The only other candidate city for the 1928 Olympics was Los Angeles, which would eventually be selected to host the Olympics four years later. In preparation for the 1932 Summer Olympics, the United States Olympic Committee reviewed the costs and revenue of the 1928 Games. The committee reported a total cost of United States dollar, US$1.183 million with receipts of US$1.165 million, giving a negligible loss of US$18,000, which was a considerable improvement over the 1924 Games. The United States won the most gold and medals over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1896 Summer Olympics
The 1896 Summer Olympics (), officially known as the Games of the I Olympiad () and commonly known as Athens 1896 (), were the first international Olympic Games held in modern history. Organised by the International Olympic Committee (IOC), which had been created by French aristocrat Pierre de Coubertin, the event was held in Athens, Greece, from 6 to 15 April 1896. Fourteen nations (according to the IOC, though the number is subject to interpretation) and 241 athletes (all males; this number is also disputed) took part in the games. Participants were all European or living in Europe, with the exception of the United States team, and over 65% of the competing athletes were Greek. Winners were given a silver medal, while runners-up received a copper medal. Retroactively, the IOC has designated the top three finishers in each event as gold, silver, and bronze medalists. Ten of the 14 participating nations earned medals. On April 6, 1896, American James Connolly became the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Olympic Games
The ancient Olympic Games (, ''ta Olympia''.), or the ancient Olympics, were a series of Athletics (sport), athletic competitions among representatives of polis, city-states and one of the Panhellenic Games of ancient Greece. They were held at the Panhellenic sanctuary, Panhellenic religious sanctuary of Olympia, Greece, Olympia, in honor of Zeus, and the Greeks gave them a aition, mythological origin. The originating Olympic Games are traditionally dated to 776 BC. The games were held every four years, or Olympiad, which became a unit of time in historical chronologies. These Olympiads were referred to based on the winner of their ''Stadion (running race), stadion'' sprint, e.g., "the third year of the eighteenth Olympiad when Ladas of Argos won the ''stadion''". They continued to be celebrated when Greece came under Greece in the Roman era, Roman rule in the 2nd century BC. Their last recorded celebration was in AD 393, under the emperor Theodosius I, but archaeological evidenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympiad
An olympiad (, ''Olympiás'') is a period of four years, particularly those associated with the Ancient Olympic Games, ancient and Olympic Games, modern Olympic Games. Although the ancient Olympics were established during Archaic Greece, Greece's Archaic Era, it was not until Hippias of Elis, Hippias that a consistent list was established and not until Ephorus of Cyme, Ephorus in the Hellenistic period that the first recorded Olympic contest was used as a Epoch (reference date), calendar epoch. Ancient authors agreed that other Olympics had been held before the race won by Coroebus of Elis, Coroebus but disagreed on how many; the convention was established to place Coroebus's victory at a time equivalent to the summer of 776 BC, 776 BC in the Proleptic Julian calendar, and to treat it as Year 1 of Olympiad 1. Olympiad 2 began with the next games in the summer of 772 BC. Thus, for N less than 195, Olympiad N is reckoned as having started in the year 780-(4\times N) ...

Diaulos (running Race)
The ''diaulos'' (, meaning "double pipe") was a double- stadion footrace of approximately , introduced in the 14th Olympiad of the ancient Olympic Games in 724 BC. The exact length of the race varied by venue due to the lack of standardized Greek measurements. For instance, the Stadium at Olympia measured , whereas the Stadium of Delphi was long. Scholars debate whether runners turned around a single post or used individual turning posts (''kampteres'') on the return leg. A single turning post could have disadvantaged runners in outer lanes, potentially adding to their distance. In contrast, inscriptions from Delphi mention "turning-posts" in the plural, and archaeological findings at Nemea also support the use of individual posts. Functionally, the diaulos resembled the modern 400-metre race. However, distinguishing it from the stadion race in ancient vase paintings is difficult due to visual similarities. One notable exception is a fragment of a Panathenaic amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
