400 Meter Hurdles
The 400 metres hurdles is a track and field hurdling event. The event has been on the Olympic athletics programme since 1900 for men and since 1984 for women. On a standard outdoor track, 400 metres is the length of the inside lane, once around the stadium. Runners stay in their lanes the entire way after starting out of the blocks and must clear ten hurdles that are evenly spaced around the track. The hurdles are positioned and weighted so that they fall forward if bumped into with sufficient force, to prevent injury to the runners. Although there is no longer any penalty for knocking hurdles over, runners prefer to clear them cleanly, as touching them during the race slows runners down. The best male athletes can run the 400 m hurdles in a time of around 46 seconds, while the very best female athletes achieve a time of around 51 seconds. The current men's and women's world record holders are Karsten Warholm with 45.94 seconds and Sydney McLaughlin with 5 ...

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 ...

Anaerobic Exercise
Anaerobic exercise is a type of exercise that breaks down glucose in the body without using oxygen; ''anaerobic'' means "without oxygen". In practical terms, this means that anaerobic exercise is more intense, but shorter in duration than aerobic exercise. The biochemistry of anaerobic exercise involves a process called glycolysis, in which glucose is converted to adenosine triphosphate (ATP), which is the primary source of energy for cellular reactions. This type of exercise leads to a buildup of lactic acid. Anaerobic exercise may be used to help build endurance, muscle strength, and power. Metabolism Anaerobic metabolism is a natural part of metabolic energy expenditure. Fast twitch muscles (as compared to slow twitch muscles) operate using anaerobic metabolic systems, such that any use of fast twitch muscle fibers leads to an increased anaerobic energy expenditure. Intense exercise lasting upwards of four minutes (e.g. a mile race) may still have considerable anaerobi ...

USA Track & Field
USA Track & Field (USATF) is the United States national governing body for the sports of track and field, cross country running, road running and racewalking (known as the sport of athletics outside the US). The USATF was known between 1979 and 1992 as ''The Athletics Congress'' (TAC) after its spin off from the Amateur Athletic Union (AAU), which governed the sport in the US through most of the 20th century until the Amateur Sports Act of 1978 dissolved its responsibility. Based in Indianapolis, USATF is a non-profit organization with a membership of more than 130,000. The organization has three key leadership positions: CEO Max Siegel, Board of Directors Chair Steve Miller, and elected President Vin Lananna. U.S. citizens and permanent residents can be USATF members (annual individual membership fee: $25 for 18-year-old member and younger, $40 for the rest), but permanent residents can only participate in masters events in the country, per World Athletics regulations.

Liberty Bell Classic
The Liberty Bell Classic was a track and field athletics event organized by the Athletics Congress as part of the 1980 Summer Olympics boycott and held at Franklin Field at the University of Pennsylvania in Philadelphia on July 16 and 17, 1980. It was named after Philadelphia's Liberty Bell. The U.S. Congress voted $10 million to fund alternative tournaments in several Olympic sports, to which athletes from boycotting countries would be invited. In addition to the Liberty Bell Classic, the U.S. Gymnastics Federation held an International Invitational tournament in Hartford, Connecticut. Earlier in the year, the United States had considered holding other games in Côte d'Ivoire, Italy, Japan, West Germany, or China. The IAAF prohibited any official track and field meets that would clash with the Olympic meet, so the Liberty Bell began three days before the Moscow Games opened (and ten days before the Olympic athletics events began). The Liberty Bell came the day after the pre ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

World Athletics Championships
The World Athletics Championships (until 2019 known as the World Championships in Athletics) are a biennial athletics competition organized by World Athletics (formerly IAAF, International Association of Athletics Federations). Alongside the Olympic Games, they represent the highest level championships of senior international outdoor athletics competition for track and field athletics globally, including marathon running and race walking. Separate World Championships are held by World Athletics for certain other outdoor events, including cross-country running and half-marathon, as well as indoor and age-group championships. The World Championships were started in 1976 in response to the International Olympic Committee dropping the men's 50 km walk from the Olympic programme for the 1976 Montreal Olympics, despite its constant presence at the games since 1932. The IAAF chose to host its own world championship event instead, a month and a half after the Olympics. [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
