Negative Split
A negative split is a racing strategy that involves completing the second half of a race faster than the first half. It is defined by the intentional setting of a slower initial pace, followed by a gradual or sudden increase of speed towards the end of the race. Alternate strategies include ''even splitting'' (racing at a steady pace) or ''sit and kick'' (also known as a sprint finish). Conversely, the act of completing the first half of a race faster than the second half is known as a positive split. The strategy of negative splitting has been documented in competitive running since the early 20th century. Runners such as Steve Prefontaine, Wilson Kipsang and Galen Rupp have used it in races. Negative split strategies are also used in swimming (including Janet Evans's 1988 Olympic gold in the 400 m freestyle) cycling, triathlon and horse racing. Similar strategies The strategies discussed below are easily confused with negative splits, because the racer can appear to be neg ...

Racing
In sport, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in "Pointe du Raz" (the most western point of France, in Brittany), and "''raz-de-marée''" (tsunami).

Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expectancy. It is assumed that the ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lactic Acid
Lactic acid is an organic acid. It has a molecular formula . It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources. Lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. The conjugate base of lactic acid is called lactate (or the lactate anion). The name of the derived acyl group is lactoyl. In solution, it can ionize by loss of a proton to produce the lactate ion . Compared to acetic acid, its p''K'' is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group. Lactic acid is chiral, consisting of two enantiomers. One ...

5000 Metres
The 5000 metres or 5000-metre run is a common long-distance running event in track and field, approximately equivalent to or . It is one of the track events in the Olympic Games and the World Championships in Athletics, run over laps of a standard track. The same distance in road running is called a 5K run; referring to the distance in metres rather than kilometres serves to disambiguate the two events. The 5000 m has been present on the Olympic programme since 1912 for men and since 1996 for women. Prior to 1996, women had competed in an Olympic 3000 metres race since 1984. The 5000 m has been held at each of the World Championships in Athletics in men's competition and since 1995 in women's. The event is almost the same length as the dolichos race held at the Ancient Olympic Games, introduced in 720 BCE. World Athletics keeps official records for both outdoor and indoor 5000-metre track events. 3 miles The 5000 metres is the (slightly longer) approximate m ...

Galen Rupp Celebrates 2012 Olympics (cropped)
Aelius Galenus or Claudius Galenus ( el, Κλαύδιος Γαληνός; September 129 – c. AD 216), often Anglicized as Galen () or Galen of Pergamon, was a Greek physician, surgeon and philosopher in the Roman Empire. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic. The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several empero ...

Honolulu Marathon
The Honolulu Marathon (branded JAL Honolulu Marathon for sponsorship reasons) is a marathon (26.2 miles or 42.2km) in Honolulu, Hawaii, first held in 1973. It is one of the world's largest marathons, taking place annually on the second Sunday in December. The marathon is popular for its location in Hawaii, and is also popular among first-time marathoners, many of whom are visitors from Japan. The 40th Honolulu Marathon, held in 2012, had 30,898 registrants, and was the second-largest marathon in the United States that year, behind the Chicago Marathon. History The race began in 1973. During its formative period (1973–1978) the Honolulu Marathon doubled in size every year—a rate that has been equaled only once. That growth, like the growth of long-distance running itself, came about not from an interest in competition, but from a quest for personal longevity and an enhanced quality of life. Former Honolulu Mayor Frank Fasi has been inducted in the Honolulu Marathon Hall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marathon
The marathon is a long-distance foot race with a distance of , usually run as a road race, but the distance can be covered on trail routes. The marathon can be completed by running or with a run/walk strategy. There are also wheelchair divisions. More than 800 marathons are held throughout the world each year, with the vast majority of competitors being recreational athletes, as larger marathons can have tens of thousands of participants. The marathon was one of the original modern Olympic events in 1896. The distance did not become standardized until 1921. The distance is also included in the World Athletics Championships, which began in 1983. It is the only running road race included in both championship competitions (walking races on the roads are also contested in both). History Origin The name ''Marathon'' comes from the legend of Philippides (or Pheidippides), the Greek messenger. The legend states that, while he was taking part in the Battle of Marathon, whi ...
