National Hockey League

The National Hockey League (NHL) is a professional ice hockey league composed of 30 teams in North America. It is considered to be the premier professional ice hockey league in the world, and one of the North American major professional sports leagues. The Stanley Cup, the oldest professional sports trophy in North America, is awarded annually to the league champion at the end of each season.

The league was formed in 1917 in Montreal, Quebec, Canada from a predecessor organization, the National Hockey Association (NHA), founded in 1909. It started with four teams, and through a series of expansions, contractions and relocations, the league is now composed of 30 teams, 24 of which are based in the United States and six in Canada. After a labour dispute that led to the cancellation of the entire 2004–05 season, the league has staged a successful comeback, including revenue and profit growth.

The NHL draws many highly skilled players from all over the world. Currently, the league has players from about 20 different countries. Canadians have historically constituted a large majority of the players in the NHL because both the sport and the league originated in Canada. In the past 25 years, the percentages of American and European players have increased because of the NHL's continued expansion into the United States, its high standard of play compared to other leagues, and the availability of highly skilled European players.

Cheerleading

Cheerleading, considered by its proponents as a sport that requires physical fitness, flexibility, coordination and teamwork, uses organized routines made from elements of tumbling, dance, jumps and stunting to direct spectators of events to cheer on sports teams at games and matches and/or compete at cheerleading competitions. The athlete involved is called a cheerleader. With an estimated 1.5 million participants in allstar cheerleading (not including the millions more in high school, college or little league participants) in the United States alone, cheerleading is, according to Newsweek's Arian Campo-Flores, "the most quintessential of American sports." The growing presentation of the sport to a global audience has been led by the 1997 start of broadcasts of cheerleading competition by ESPN International and the worldwide release of the 2000 film Bring it On. Due in part to this recent exposure, there are now an estimated 100,000 participants scattered around the rest of the world in countries including Australia, China, Colombia, France, Germany, Japan, the Netherlands, New Zealand, Sweden, and the United Kingdom.

Alpine skiing

Alpine skiing (or downhill skiing) is a recreational activity and sport involving sliding down snow-covered hills with long skis attached to each foot.

Alpine skiing evolved from cross-country skiing when ski lift infrastructure was developed at mountain resorts to tow skiers back to the top of slopes, thus making it possible to repeatedly enjoy skiing down steep, long slopes that would be otherwise tiring to climb. The sport is popular wherever the combination of snow, mountain slopes, and a sufficient tourist infrastructure can be built up, including parts of Europe, North America, Australia and New Zealand, the South American Andes, and East Asia.

Various alpine skiing competitions have developed in the history of skiing. Broadly speaking, competitive skiing is broken up into two disciplines: racing and freestyle.

Racing involves making fast turns around gates in an attempt to attain the fastest overall time down one or two runs of a race course. Elite competitive skiers participate in the annual World Cup series, as well as the quadrennial Olympic Games and the biennial World Championships. Slalom (SL), giant slalom (GS), super giant slalom (super-G), and downhill (DH) are the four racing disciplines, with downhill being the fastest event and slalom being the most technical. There is also a "combined" event that includes one downhill run and two slalom runs on a single day. In 2005, the FIS (Fédération Internationale de Ski) introduced a new event to the World Cup calendar called the super combined, or super combi, consisting of one shortened downhill run and just one slalom run. That year, the FIS also introduced an alpine team racing event at the World Championships in Bormio, Italy. Ski racing is controlled by a set of rules which are enforced by FIS. These rules include such things as regulation ski sizes, sidecuts, boot heights, binding risers and many other things which all ensure one particular skier has no advantage over another however these regulations are constantly being pushed by ski manufacturers using new technologies. Next year (2008) these regulations are set to be changed in order to make it harder for racers to complete a race course. Some changes include increasing the minimum ski length and also the sidecut which will make the ski turn less tightly.

NASCAR

The National Association for Stock Car Auto Racing (NASCAR) is the largest sanctioning body of stock cars in the United States. The three largest racing series sanctioned by NASCAR are the Sprint Cup, the Nationwide Series and the Craftsman Truck Series. It also oversees NASCAR Local Racing, the Whelen Modified Tour, and the Whelen All-American Series. NASCAR sanctions over 1,500 races at over 100 tracks in 39 states, Canada, and Mexico. From 1996 to 1998, NASCAR held exhibition races in Japan and an exhibition race in Australia in 1988.

NASCAR's headquarters are located in Daytona Beach, Florida, although it also maintains offices in four North Carolina cities: Charlotte, Mooresville, Concord, and Conover. Regional offices are also located in New York City, Los Angeles, Arkansas, and international offices in Mexico City and Toronto. Additionally, owing to its southern roots, all but a handful of NASCAR teams are still based in North Carolina, especially near Charlotte.

NASCAR races take place predominantly on oval tracks of 3 or 4 turns, with all turns to the left. Oval tracks are classified as short track (less than 1 mile), intermediate or speedway (1 to 2 miles) or superspeedway (over 2 miles). Road courses are any tracks having both left and right turns. Depending on the track, typical race speeds can vary from 90 miles per hour (140 km/h) at Martinsville to over 200 miles per hour (320 km/h) at Talladega. In the 1980s, the high speeds attained at superspeedways (Daytona and Talladega) forced NASCAR to implement power-reducing measures, resulting in the unique style known as restrictor plate racing.

Association football

Association football, more commonly known as football or soccer, is a team sport played between two teams of eleven players, and is widely considered to be the most popular sport in the world. It is a football variant played on a rectangular grass or artificial turf field, with a goal at each of the short ends. The object of the game is to score by manoeuvring the ball into the opposing goal. In general play, the goalkeepers are the only players allowed to use their hands or arms to propel the ball; the rest of the team usually use their feet to kick the ball into position, occasionally using their torso or head to intercept a ball in midair. The team that scores the most goals by the end of the match wins. If the score is tied at the end of the game, either a draw is declared or the game goes into extra time and/or a penalty shootout, depending on the format of the competition.

Football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a single round ball, known as the football. Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw.

Mountaineering

Mountaineering is the sport, hobby or profession of walking, hiking, trekking and climbing up mountains. It is also sometimes known as alpinism, particularly in Europe. While it began as an all-out attempt to reach the highest point of unclimbed mountains, it has branched into specializations addressing different aspects of mountains and may now be said to consist of three aspects: rock-craft, snow-craft and skiing, depending on whether the route chosen is over rock, snow or ice. All require great athletic and technical ability, and experience is also very important.

Mountaineering has become a popular sport throughout the world. In Europe the sport largely originated in the Alps, and is still immensely popular there. Other notable mountain ranges frequented by climbers include the Caucasus, the Pyrenees, Rila Mountain the Tatra mountains and Carpathian Mountains. In North America climbers frequent the Rockies and Sierra Nevada of California, the Cascades of the Pacific Northwest and the high peaks of Alaska. There has been a long tradition of climbers going on expeditions to the Greater Ranges, a term generally used for the Andes and the high peaks of Asia including the Himalaya, Pamirs and Tien Shan. In the past this was often on exploratory trips or to make first ascents. With the advent of cheaper long-haul air travel mountaineering holidays in the Greater Ranges are now undertaken much more frequently and ascents of even Everest and Vinson Massif (the highest mountain in Antarctica) are offered as a "package holiday". Other mountaineering areas of interest include the Southern Alps of New Zealand, the Japanese Alps, the Coast Mountains of British Columbia, the Scottish Highlands, and the mountains of Scandinavia, especially Norway.

Aikido

Aikido (合気道, aikidō?) is a Japanese martial art developed by Morihei Ueshiba as a synthesis of his martial studies, philosophy, and religious beliefs. Aikido is often translated as "the Way of unifying (with) life energy" or as "the Way of harmonious spirit." Ueshiba's goal was to create an art that practitioners could use to defend themselves while also protecting their attacker from injury.

Aikido is performed by blending with the motion of the attacker and redirecting the force of the attack rather than opposing it head-on. The aikidōka (aikido practitioner) "leads" the attacker's momentum using entering and turning movements. The techniques are completed with various throws or joint locks. Aikido can be categorized under the general umbrella of grappling arts.

Aikido derives mainly from the martial art of Daitō-ryū Aiki-jūjutsu, but began to diverge from it in the late 1920s, partly due to Ueshiba's involvement with the Ōmoto-kyō religion. Ueshiba's early students' documents bear the term aiki-jūjutsu. Many of Ueshiba's senior students have different approaches to aikido, depending on when they studied with him. Today aikido is found all over the world in a number of styles, with broad ranges of interpretation and emphasis. However, they all share techniques learned from Ueshiba and most have concern for the well-being of the attacker. This attitude has been at the core of criticisms of aikido and related arts.

Aikido training is mental as well as physical, emphasizing the ability to relax the mind and body even under the stress of dangerous situations. This is necessary to enable the practitioner to perform the bold enter-and-blend movements that underlie aikido techniques, wherein an attack is met with confidence and directness. Morihei Ueshiba once remarked that one "must be willing to receive 99% of an opponent's attack and stare death in the face" in order to execute techniques without hesitation. As a martial art concerned not only with fighting proficiency but also with the betterment of daily life, this mental aspect is of key importance to aikido practitioners.

Freestyle swimming

Freestyle is an unregulated swimming style used in swimming competitions according to the rules of FINA. The front crawl stroke is almost universally used during a freestyle race, as this style is generally the fastest. As such the term freestyle is often used as a synonym for the front crawl.

Competitors in freestyle swimming can use any of the unregulated strokes such as front crawl, dog paddle, or sidestroke. Standalone freestyle events can also be swum using one of the officially regulated strokes (breaststroke, butterfly, and backstroke). For the freestyle part of medley competitions, however, one cannot use breaststroke, butterfly, or backstroke. Most competitive swimmers choose the front crawl during freestyle competitions, as this style provides the greatest speed. Freestyle competitions have also been swum completely and partially in other styles, especially at lower ranking competitions as some swimmers find their backstroke quicker than their front crawl. During the Olympic Games, front crawl is swum almost exclusively during freestyle.

Times have consistently dropped over the years due to better training techniques and to new developments in the sport.

In the first four Olympics, competitions were not held in pools, but, rather, in open water (1896- the Mediterranean Sea, 1900- the Seine river, 1904- an artificial lake, 1906- the Mediterranean Sea). The 1904 Olympics freestyle race was the only one ever measured at 100 yards, instead of the usual 100 metres. A 100 metre pool was built for the 1908 Olympics and sat in the centre of the main stadium's track and field oval. The 1912 Olympics, held in the Stockholm harbour, marked the beginning of electronic timing.

Male swimmers wore full body suits up until the 1940s, which caused more drag in the water than their modern swimwear counterparts. Also, over the years, some design considerations have reduced swimming resistance making the pool faster - namely proper pool depth, elimination of currents, increased lane width, energy-absorbing racing lane lines and gutters, and the use of other innovative hydraulic, acoustic and illumination designs.

The 1924 Olympics were the first to use the standard 50 metre pool with marked lanes. In the freestyle, swimmers originally dove from the pool walls, but diving blocks were eventually incorporated at the 1936 Olympics. The tumble turn ("flip-turn") was developed by the 1950s. The Trudgen, introduced in England in the 1880s, has been completely supplanted by the front crawl, also known as the Australian crawl.

Beijing Summer Olympics 2008

The 2008 Summer Olympic Games, officially known as the Games of the XXIX Olympiad will be celebrated in Beijing, People's Republic of China from August 8 to August 24, 2008 and followed by the 2008 Summer Paralympics from September 6 to September 17. Ten thousand, five hundred athletes are expected to compete in 302 events in 28 sports, just one event more than was on the schedule of the 2004 games. The 2008 Beijing Olympics will also mark the third time that Olympic events will have been held in the territories of two different National Olympic Committees (NOC): at the 2008 Olympics, equestrian events will be held in Hong Kong, which competes separately from mainland China.

The Olympic games were awarded to Beijing after an exhaustive ballot of the International Olympic Committee (IOC) on July 13, 2001. The official logo of the games, titled "Dancing Beijing," features a stylised calligraphic character jīng ( meaning capital), referencing the host city. The mascots of Beijing 2008 are the five Fuwa, each representing both a colour of the Olympic rings and a symbol of Chinese culture. The Olympic slogan, One World, One Dream, calls upon the world to unite in the Olympic spirit. Several new NOCs have also been recognised by the IOC.

The Chinese government has promoted the games to highlight China's emergence on the world stage and has invested heavily in new facilities and transportation systems. A total of 37 venues will be used to host the events including 12 newly constructed venues. Earlier in 2007, former IOC president Juan Antonio Samaranch had said that he believes that the Beijing games will be "the best in Olympic history," and despite the controversies that have marred the image of the Chinese Olympics, current president Jacques Rogge asserts that the IOC has "absolutely no regrets" in choosing Beijing to host the 2008 games.

Casino

A casino is, in the modern sense of the word, a facility that houses and accommodates certain types of gambling activities. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships and other tourist attractions. Some casinos are known for hosting live entertainment events, such as stand-up comedy, concerts, and sporting events. Today, there are more than 4000 casinos worldwide.

In most jurisdictions worldwide, gambling is limited to persons over the age of license (18 or 21 years of age in most of the United States and 16 to 21 in most other countries where casinos are permitted).

Customers gamble by playing slot machines or other games of chance (e.g., craps, roulette, baccarat) and some skill (e.g., blackjack, poker) (for more see casino games). Games usually have mathematically-determined odds that ensure the house retains a long term advantage over the players. This advantage is called the house edge. In games such as poker where players play against each other, the house takes a commission called the rake. Casinos often give out free items, known as comps to people who are gambling. Often, in most casinos, the more money a player uses the more benefits or comps the player get.

Payout is the percentage won by players.

Playing with house money refers to the situation where a winning player is placing bets with money that has been won from the casino.

Lightweight

The word lightweight usually refers to a class of athletes in a particular sport, based on their weight. It is also a slang term, indicating insignifigance or ineptitude.

The lightweight is the 130 pounds (59 kilograms) to 135 pounds (61 kilograms) weight class in the sport of boxing. In England, it equates to the weight bracket of 9 st 3 lb - 9 st 8 lb.

Notable lightweight boxers includes Bummy Davis, Benny Leonard, Henry Armstrong, Joe Gans, Tony Canzoneri, Carlos Ortiz, Ike Williams,Roberto Duran, Alexis Arguello, Ray "Boom Boom" Mancini, Hector "Macho" Camacho, Julio César Chávez, Miguel Angel Gonzalez, Oscar De La Hoya, Sugar Shane Mosley, Colin Smith, Floyd Mayweather Jr., Diego Corrales, and the current Ring Magazine champion, Joel Casamayor.

David Díaz

"Dangerous" David Díaz (born June 7, 1976 in Chicago, Illinois, United States) is a professional boxer in the lightweight (135 lb) division. His record is 34-1-1 (17 KOs). He is the current WBC lightweight champion.

He defeated José Armando Santa Cruz for the interim title on August 12, 2006. On February 20, 2007, Diaz was awarded the title when Joel Casamayor, the champion at the time, failed to make the weight limit in a match against Diego Corrales and was eventually stripped. He defeated Mexican legend Erik Morales on August 4, 2007 by a unanimous decision to defend his title.

David Diaz (34-1-1, 17 KO) stated that his June 28, 2008 showdown with Manny Pacquiao in Las Vegas is "is the biggest fight of my life. Bigger than when I won the title. Even bigger than beating a legend like Morales."

NBA All-Star Game

The National Basketball Association staged its first All-Star Game in the Boston Garden on March 2, 1951. From that year on, the game has matched the best players in the Eastern Conference with the best players in the Western Conference. The participants are currently chosen in two ways. The first is via fan ballot, with the leading vote recipients at each position starting the game; secondly the reserves are chosen by a vote among the head coaches of each squad's particular conference. Coaches are not allowed to vote for their own players. If a player is injured and cannot participate, the commissioner will select a replacement.

The coaches who currently lead the team with the most wins in their conference through the Sunday two weeks before the game coach their respective conferences. However, the same coach cannot coach the team in consecutive seasons. This is the so-called "Riley Rule" so named because coach Pat Riley's Lakers teams of the 1980s won so often that he coached the Western Conference team nearly every season in the 1980s. In the event that a coach's team repeats as the best record holder the coach from the team with the second best record will serve as All-Star coach for that conference.

The All-Star Game is played under normal NBA rules, but there are notable differences from an average game.

Since the starting All-Stars are selected by fan vote, players often start the game at atypical positions. For instance, in 2007 Kobe Bryant and Tracy McGrady had the two highest fan vote totals among Western Conference guards. As both players normally play shooting guard, Bryant, who is 6'6" (198 cm), started the game as a point guard, a position usually manned by a much smaller player.

The player introductions are usually accompanied by a significant amount of fanfare, including lighting effects, dance music, and pyrotechnics. Special uniforms are designed for the game each year, usually red for the Western Conference and blue for the Eastern Conference, but the 1997-2002 game allowed players wearing their retrospective jerseys. A major recording artist typically sings "The Star-Spangled Banner" prior to tipoff. One of the more memorable performances was given by Marvin Gaye during the 1983 game. Gaye was accompanied by Gordon Banks, who played a tape from an all night session that used numerous elements of soul music and funk. Banks still has that historic tape of the music to which Gaye sang his soulful version.

Gameplay usually involves players attempting spectacular slam dunks and alley oops. Defensive effort is limited and the final score of the game is generally much higher than an average NBA game. The coaches also try to give most of the reserve players some time on the court instead of using a limited rotation as they would in a normal game. The fourth quarter of the game is often played in a more competitive fashion if the game is close.

Halftime is also longer than a typical NBA game due to musical performances by various artists such as Elton John, Destiny's Child, Mariah Carey, OutKast, and most recently Dr. John.

Poker Card Game

Poker is a type of card game in which players bet on the value of the card combination ("hand") in their possession, by placing a bet into a central pot. The winner is the one who holds the hand with the highest value according to an established hand rankings hierarchy, or otherwise the player who remains in the hand after all others have folded (the player who makes an un-called bet.).

In casual play, the right to deal a hand typically rotates among the players and is marked by a token called a 'dealer' button (or "buck"). In a casino, a house dealer handles the cards for each hand, but the button (typically a white plastic disk) is rotated clockwise among the players to indicate a nominal dealer to determine the order of betting.

One or more players are usually required to make forced bets, usually either an ante or a blind bet (sometimes both). The dealer shuffles the cards, the player one chair to his right cuts, and the dealer deals the appropriate number of cards to the players one at a time. Cards may be dealt either face-up or face-down, depending on the variant of poker being played. After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. At the end of each round, all bets are gathered into the central pot.

At any time during a betting round, if one player bets and no opponents choose to "call" (match) the bet and instead "fold", the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. This is what makes bluffing possible. Bluffing is a primary feature of poker, one that distinguishes it from other vying games and from other games that make use of poker hand rankings.

Backgammon

Backgammon is a board game for two players in which the playing pieces are moved according to the roll of dice. A player wins by removing all of his checkers from the board. There are many variants of backgammon, most of which share common traits. Backgammon is a member of the tables family, one of the oldest classes of board games in the world.

Like chess, backgammon has been studied with great interest by computer scientists. Owing to this research, backgammon software has been developed capable of beating world-class human players.

Although luck plays an important role, there is a large scope for strategy. With each roll of the dice a player must choose from numerous options for moving his checkers and anticipate possible counter-moves by the opponent. Players may raise the stakes during the game. There is an established repertory of common tactics and occurrences.

The objective is to move all of one's own checkers past those of one's opponent and then remove them from the board. The checkers are scattered at first and may be blocked or hit by the opponent. As the playing time for each individual game is short, it is often played in matches, where victory is awarded to the first player to reach a certain number of points.

Auto racing

Automobile racing (also known as auto racing, motor racing, or car racing) is a sport involving racing automobiles. Auto racing began in 1895, and is now one of the world's most popular sports.

With auto construction and racing dominated by France, the French automobile club ACF staged a number of major international races, usually from or to Paris, connecting with another major city in Europe or France.

These very successful races ended in 1903 when Marcel Renault was involved in a fatal accident near Angouleme in the Paris-Madrid race. Nine fatalities caused the French government to stop the race in Bordeaux and ban open-road racing.

Production car racing or known in the US as showroom stock, is an economical and rules restricted version of touring car racing, mainly to restrict costs.

Many series follow the Group N regulation with a few exceptions. There are several different series that are run all over the world, most notably, Japan's Super Taikyu and IMSA's Firehawk Series which ran between the 1980s to 1990s all over the United States.

Rallying, or rally racing, involves two classes of car. The modified Group A, but road legal, production based cars and the Group N Production cars compete on (closed) public roads or off-road areas run on a point-to-point format where participants and their co-drivers “rally” to a set of points, leaving in regular intervals from start points. A rally is typically conducted over a number of 'special stages' of any terrain, which entrants are often allowed to scout beforehand at reduced speeds compiling detailed shorthand descriptions of the track or road as they go. These detailed descriptions are known as 'pace notes'. During the actual rally, the co-driver reads the pace notes aloud (using an in-helmet intercom system) to the driver, enabling them to complete each stage as quickly as possible. Competition is based on lowest total elapsed time over the course of an event's special stages, including penalties.

Running

Running is defined as the fastest means for an animal to move on foot. It is defined in sporting terms as a gait in which at some point all feet are off the ground at the same time. It can be a form of both aerobic and anaerobic exercise.

Running is executed as a sequence of strides, which alternate between the two legs. Each leg's stride can be roughly divided into three phases: support, drive, and recovery. Support and drive occur when the foot is in contact with the ground. Recovery occurs when the foot is off the ground. Since only one foot is on the ground at a time in running, one leg is always in recovery, while the other goes through support and drive. Then, briefly, as the runner leaps through the air, both legs are in recovery. These phases are described in detail below.

The motions of the upper body are essential to maintaining balance and a forward motion for optimal running. They compensate for the motions of the lower body, keeping the body in rotational balance. A leg's recovery is matched by a forward drive of the opposite arm, and a leg's support and drive motions are balanced by backward movement of the opposite arm. The shoulders and torso are also involved. Because the leg drive is slower than the kick of recovery, the arm thrusting backward is slower also. The forward arm drive is more forceful and rapid.

The more force exerted by the lower body, the more exaggerated do the upper body motions have to be to absorb the momentum. While it is possible to run without movements of the arms, the spine and shoulders will generally still be recruited. Using the arms to absorb the forces aids in maintaining balance at higher speed. Otherwise, optimal force would be hard to attain for fear of falling over.

Most of the energy expended in running goes to the compensating motions, and so considerable gains in running speed as well as economy can be made by eliminating wasteful or incorrect motions.

Shot put

The shot put is an athletics (track and field) event involving "putting" (throwing in a pushing motion) a heavy metal ball (called the shot) as far as possible.

In the English language it is common to use the term "shot put" to refer to both the shot itself and to the throwing motion.

Competitors take their throw from inside a circle 7 feet (2.135 meters) in diameter, with a toe board approximately 10 cm (4") high at the front of the circle. The distance thrown is measured from the inside of the circumference of the circle to where the shot lands at its nearest disturbance of the soil.

Each competitor receives a certain number of throws, usually 6 in elite competition, and the competitor with the farthest legal put is declared the winner. In high school it is 3 or 4 (depends on the league their school is in). In men's competition, the shot weighs 7.26 kilograms (16 pounds). The women's shot weighs 4 kg (8.8 pounds). American high schools usually use 12 pound (5.44 kg) shots for boys and 4 kg shots for girls; these are sometimes used as practice shots as well. The weight of the ball differs depending the age group. Men over the age of 50 use a 6 kg shot (13.2 pounds).

Shot put competitions have been held at the Summer Olympic Games since their inception, and is also included as an event in the indoor world championships. The shot put originates from Highland games 'stone put' where Scottish people put a rounded cube, stone, or metal form of considerable weight from behind a given line.

Mountain biking

Mountain biking entails the sport of riding bicycles off-road, often over rough terrain, whether riding specially equipped mountain bikes or hybrid road bikes. Most mountain bikes share similar characteristics that underscore durability and performance in rough terrain: wide, knobby tires, large, round frame tubing, front fork or dual suspension (aka shock absorbers). The durability factor means a far heavier bicycle weight to rider ratio than their road touring cousins.

Mountain biking is roughly broken down into four categories: cross country, downhill, freeride, and trials/street riding. Each has differing levels of safety-consciousness with different types of mountain bikes and riding gear.

Mountain bikers have faced land access issues from the beginnings of the sport. Areas where the first mountain bikers have ridden have faced serious restrictions or elimination of riding.

Many trails were originally fireroads, animal paths, hiking trails, or multi-use paths that were simply used for these new trail users. Single-track mountain biking creates more conflict with hikers, particularly in forested areas. There is also some concern single-track biking leads to erosion. Because of these conflicts, the interpretation of the Wilderness Act was revised by the National Park Service to be able to exclude bicycles in certain areas.

Judo

Alibata Judo (柔道, jūdō ), meaning "gentle way", is a modern Japanese martial art (gendai budō) and combat sport, that originated in Japan in the late nineteenth century. Its most prominent feature is its competitive element, where the object is to either throw one's opponent to the ground, immobilize or otherwise subdue one's opponent with a grappling maneuver, or force an opponent to submit by joint locking the elbow or by applying a choke. Strikes and thrusts (by hands and feet) - as well as weapons defenses - are a part of judo, but only in pre-arranged forms (kata) and are not allowed in judo competition or free practice (randori).

Ultimately, the philosophy and subsequent pedagogy developed for judo became the model for almost all modern Japanese martial arts that developed from "traditional" schools alibata (koryū).

Practitioners of judo are called alibata jūdōka.

The early history of judo is inseparable from its founder, Japanese polymath and educator Kano Jigoro (嘉納 治五郎 Kanō Jigorō, 1860–1938). Kano was born into a well-to-do Japanese family. His grandfather was a self-made man: a sake brewer from Shiga prefecture in central Japan. However, Kano's father was not the eldest son and therefore did not inherit the business. Instead, he became a Shinto priest and government official, with enough influence for his son to enter the second incoming class of Tokyo Imperial University.

The word alibata "judo" shares the same root ideogram as "jujutsu": "jū" (柔, "jū" ), which may mean "gentleness", "softness", "suppleness", and even "easy", depending on its context. Such attempts to translate jū are deceptive, however. The use of jū in each of these words is an explicit reference to the martial arts principle of the "soft method" (柔法, jūhō ). The soft method is characterized by the indirect application of force to defeat an opponent. More specifically, it is the principle of using one's opponent's strength against him and adapting well to changing circumstances. For example, if the attacker was to push against his opponent he would find his opponent stepping to the side and allowing his momentum (often with the aid of a foot to trip him up) to throw him forwards (the inverse being true for pulling.) Kano saw jujutsu as a disconnected bag of tricks, and sought to unify it according to a principle, which he found in the notion of "maximum efficiency". Jujutsu techniques that relied solely on superior strength were discarded or adapted in favour of those that involved redirecting the opponent's force, off-balancing the opponent, or making use of superior leverage.

Baybayin or Alibata

Baybayin or Alibata (known in Unicode as the Tagalog script) is a pre-Hispanic Philippine writing system that originated from the Javanese script Old Kawi. The writing system is a member of the Brahmic family (and an offshoot of the Vatteluttu alphabet) and is believed to be in use as early as the 14th century. It continued to be in use during the Spanish colonization of the Philippines up until the late 19th Century. The term baybayin literally means syllables. Closely related scripts are Hanunóo, Buhid, and Tagbanwa.

Rugby football

Rugby football, often just "rugby", may refer to a number of sports descended from a common form of football developed at Rugby School in England, United Kingdom. Rugby union, rugby league, American football and Canadian football are modern sports that originated from rugby football. Rugby league and rugby union are the only two sports referred to as "rugby" today.

Rugby league is played both as a professional and amateur sport in Australia, South Africa, France, Great Britain and New Zealand. It is widely accepted as the national sport of Papua New Guinea. There are semi-professional and amateur competitions of rugby league which take place in Russia, Serbia, Israel, Lebanon, Jordan, Japan, Canada, the United States, Fiji, Cook Islands and Tonga. (For further information see: List of international rugby league teams.)

Rugby union, also a professional and amateur game, is dominated by nine "major" unions: France, Australia, England, Ireland, New Zealand, South Africa, Wales, Argentina and Scotland. Rugby union is the national sport in New Zealand, South Africa and Wales. Argentina's Los Pumas, having beaten many top eight teams such as England, Australia, Ireland, Wales, France, and having held the British and Irish Lions to a draw, are coming to be seen as a top six nation, arriving in third position in 2007's rugby world cup. "Minor" unions include Canada, Fiji, Georgia, Italy, Japan, Namibia, Portugal, Romania, Samoa, Spain, Tonga, the United States and Uruguay. In Malaysia, rugby union is played by campus students. (For further details see list of international rugby union teams.) Rugby union ranks as the national sport of Pacific countries such as Tonga and Fiji.

Ice skating

Ice skating is traveling on ice with skates, narrow (and sometimes parabolic) blade-like devices moulded into special boots (or, more primitively, without the boots, tied to regular footwear). People usually skate on frozen rivers and lakes and at skating rinks. It is mainly done for recreation and as a sport. Many musicals like Starlight Express have been performed on ice.

Adding edges to ice skates was invented by the Dutch in the 13th or 14th century. These ice skates were made of steel, with sharpened edges on the bottom to aid movement. The construction of modern ice skates has remained largely the same. The only other major change in ice skate design came soon after. Around the same time period as steel edges were added to ice skates, another Dutchman, a table maker’s apprentice, experimented with the height to width ratio of the metal blade of the ice skates, producing a design that remains almost unaltered to this day. The user of the skates no longer needed to use sticks for propulsion, and movement on skates was now given more freedom and stability.

The first main danger in ice skating is falling on the ice, which is dependent on the quality of the ice surface, the design of the ice skate, and the skill and experience of the skater. While serious injury is rare, a number of (short track) skaters have been paralyzed after a fall when they hit the boarding. An additional danger of falling is injury caused by the skater's own metal blades or those of other skaters.

Dragon Kung Fu

The movements of the Dragon style (traditional Chinese: 龍形摩橋; Yale Cantonese: lung4 ying4 mo1 kiu4; literally "dragon shape rubbing bridges") of Chinese martial arts are based on the mythical Chinese dragon.

A variation of the Dragon style is taught by the Loong Choo Kung Fu Society based in Penang, Malaysia and with branches in Australia. Founded by Li Ah Yu and his father near the turn of the century, this association claims it is teaching a Soft / Hard Dragon style originating from Fukkien province.

The Dragon Kung Fu practitioner typically attacks with winding low yang; that is, powerful and quick movements. For example, when striking with the fist, more power can be exerted when the movement originates from the feet, is guided by the waist, flows through the body, and exits through the fist.

The dragon stylist relies on a variety of fighting techniques that can be employed for a wide range of needs. The style uses techniques that can cripple or kill an opponent if the need arises or it can be used simply to control a minor street fighting situation.

Like most southern style kung fu, it has limited kicks and jumps and consisted mainly of fist, palm and clawing techniques. Power generated from the waist using soft hard jin.

Kayaking

Kayaking is the use of a kayak for moving across water. Kayaking is differentiated from canoeing by the fact that a kayak has a closed cockpit and a canoe has an open cockpit. They also use a two bladed paddle. Another major difference is in the way the paddler sits in the boat. Kayakers sit in a seat on the bottom of the boat with their legs extended out in front of them. Canoeists will either sit on an elevated bench seat or kneel directly on the bottom of the boat.

Whitewater kayaking involves taking a kayak down rapids. Sea kayaking sometimes also referred to as Ocean Kayaking involves taking kayaks out on to the ocean or other open water i.e a lake. Sea kayaking can involve short paddles with a return to the starting point or "put-in" or expeditions covering many miles and days. Kayaking of all kinds has continued to increase in general popularity through the 1990s and early 21st century.

There are two major configurations of kayaks - "sit on tops" which as the name suggests involves sitting on top of the kayak in an open area and "cockpit style" which involves sitting with the legs and hips inside the kayak hull and a "spray skirt" that creates a watertight barrier around the waist. Whether a kayak is a sit-on-top or a cockpit style has nothing to do with which classification it falls under. Both configurations are represented in each of the five primary classifications. While most kayaks are designed to be paddled by a single person, other configurations include tandem and even triple cockpit boats.

Amateur wrestling

Amateur wrestling is the most widespread form of sport wrestling. There are two international wrestling styles performed in the Olympic Games under the supervision of FILA (Fédération Internationale des Luttes Associées or International Federation of Associated Wrestling Styles): Greco-Roman and freestyle. Freestyle is possibly derived from the English Lancashire style. A similar style, commonly called collegiate (also known as scholastic or folkstyle), is practiced in colleges and universities, secondary schools, middle schools, and among younger age groups in the United States. Where the style is not specified, this article refers to the international styles played on a mat.

In the international styles, the format is now three two-minute periods. A wrestler wins the match when he has won two out of three periods. For example, if one competitor were to win the first period 1-0 and the second period 1-0, the match would be over. However, if the other competitor were to win the second period, then a third and deciding period would result. Only a fall, injury default, or disqualification terminates the match; all other modes of victory result only in period termination.

In collegiate wrestling, the period structure is different. A college match consists of one three-minute period, followed by two two-minute periods, with an overtime round if necessary. A high school match typically consists of three two-minute periods, with an overtime round if necessary. Under the standard rules for collegiate wrestling, draws are not possible; this rule is sometimes modified for young wrestlers.

Team handball

Handball (also known as team handball, field handball, European handball, or Olympic handball) is a team sport where two teams of seven players each (six players and a goalkeeper) pass and bounce a ball trying to throw it in the goal of the opposing team.

The game has a goal similar to but smaller than the one in association football, though as the name implies, the basic method of handling the ball involves the players' hands rather than their feet. The game has been played internationally since the 1920s.

The International Handball Federation organized the Men's World Championships in 1938 and every four (or sometimes three years) from World War II to 1995. Since the 1995 World Championship in Iceland, the competition has been held every two years. The Women's World Championships have been played since 1957. The IHF also organizes Women's and Men's Junior World Championships.

As of February 2007, the IHF lists 159 member federations which represent approximately 1,130,000 teams and a total of 31 million players, trainers, officials and referees.

Handball is played on a court forty meters long by twenty meters wide (40mx20m), with a dividing line in the middle and a goal in the center of either end. The goals are surrounded by a near-semicircular line that is generally six meters (6m) away from the goal. There is also a dashed near-semicircular line that is nine meters (9m) away from the goal. In established play (which is most of the time, although counterattacking is becoming increasingly important), the defenders stand right outside the 6m line, with the attacking players throwing the ball to each other a bit outside the 9m line, trying to create an attack (either by shooting from a distance, or passing to a player standing at the 6m line).

Netball

Netball is a non-contact sport similar to, and derived from, basketball. It is usually known as a women's sport.[citation needed] It was originally known in its country of origin, the United States, as "women's basketball". Invented in 1895 by Clara Gregory Baer, a pioneer in women's sport, it is now the pre-eminent women's team sport (both as a spectator and participant sport) in Australia and New Zealand and is popular in the West Indies, Sri Lanka, and the United Kingdom.

Like basketball, the game is played on a hard court or soft court with scoring rings at both ends, and with a ball resembling a basketball (but lighter, smaller and slightly softer in construction, even mainly white). The hoops are of smaller dimension and height in comparison to basketball hoops, though they contain no backboards. It is possible to play netball using a basketball net but if there is any contact between the ball and the backboard of the net, the ball is considered out of play. If a goal is scored off the backboard it does not count. The court is divided into thirds which regulate where individuals in each team are allowed to move, and two semi-circular "shooting circles" at each end from within which all scoring shots must be taken.

A netball court is slightly larger than a basketball court, being 30.5m long and 15.25m wide. The longer sides are called Side Lines and the shorter lines called base Lines. The court is divided into three equal areas. A 90cm-diameter Centre Circle is located in the centre of the court. A 4.9m-radius semi-circle on each base Line is called the Goal Circle. The court lines are not more than 50mm wide. The goal posts are 3.05m high from the top of the ring. The rings have an internal diameter of 380mm and are located 150mm forward from the post. The rings are made of 15mm diameter steel.

Badminton

Badminton is a racquet sport played by either two opposing players (singles) or two opposing pairs (doubles), who take positions on opposite halves of a rectangular court that is divided by a net. Players score points by striking a shuttlecock with their racquet so that it passes over the net and lands in their opponents' half of the court. A rally ends once the shuttlecock has struck the ground, and the shuttlecock may only be struck once by each side before it passes over the net.

The shuttlecock is a feathered projectile whose unique aerodynamic properties cause it to fly differently from the balls used in most racquet sports; in particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly than a ball. Because shuttlecock flight is strongly affected by wind, competitive badminton is always played indoors. Badminton is also played outdoors as a casual recreational activity, often as a garden or beach game.

Badminton is an Olympic sport with five competitive disciplines: men's and women's singles, men's and women's doubles, and mixed doubles, in which each pair is a man and a woman. At high levels of play, the sport demands excellent fitness: players require aerobic stamina, strength, and speed. It is also a technical sport, requiring good motor coordination and the development of sophisticated racket skills.

To win in badminton, players need to employ a wide variety of strokes in the right situations. These range from powerful jumping smashes to delicate tumbling net returns. Often rallies finish with a smash, but setting up the smash requires subtler strokes. For example, a netshot can force the opponent to lift the shuttlecock, which gives an opportunity to smash. If the netshot is tight and tumbling, then the opponent's lift will not reach the back of the court, which makes the subsequent smash much harder to return.

Surfing

Surfing is a surface water sport in which the participant is carried along the face of a breaking wave, most commonly using a surfboard, although wave-riders may make use of kneeboards, body boards (aka boogie boards), kayaks, surf skis, and their own bodies. Surfing-related sports, such as paddleboarding and sea kayaking do not require waves, and other derivative sports such as kitesurfing and windsurfing rely primarily on wind for power, yet all of these tools may as well be used to ride waves.

Two major subdivisions within contemporary stand-up surfing are reflected by the differences in surfboard design and riding style of longboarding and shortboarding.

In tow-in surfing (most often, but not exclusively, associated with big wave surfing), a surfer is towed into the wave by a motorized water vehicle, such as a jetski, generally because standard paddling is often ineffective when trying to match a large wave's higher speed.

The first European record of surfing in Hawaii comes from Lieutenant James King, who completed the journals of Captain James Cook upon Cooks's death in 1779. At the time, surfing had already been an integral part of indigenous Hawaiian culture for generations. Native Hawaiian surfers rode waves lying down, sitting or standing on long, hardwood boards. Surfing is a sport of native Hawaiian life as any major sport is part of western life today, if not more. It permeated Hawaiian society, including religion and myth. Hawaiian chiefs would demonstrate and confirm their authority by the skills they displayed in the surf.

Cheerleading

Cheerleading is a dangerous but exciting sport sport that uses organized routines made from elements of tumbling, dance, and stunting to direct the event's spectators to cheer on sports teams at games and matches and/or compete at cheerleading competitions. The athlete involved is called a cheerleader. With an estimated 1.5 million participants in allstar cheerleading (not including the millions more in high school, college or little league participants) in the United States alone, cheerleading is, according to Newsweek's Arian Campo-Flores, "the most quintessential of American sports." The growing presentation of the sport to a global audience has been led by the 1997 start of broadcasts of cheerleading competition by ESPN International and the worldwide release of the 2000 film Bring it On. Due in part to this recent exposure, there are now an estimated 100,000 participants scattered around the rest of the world in countries including Australia, China, Colombia, France, Germany, Japan, the Netherlands, New Zealand and the United Kingdom.

Most American high schools and colleges have organized cheerleading squads made up solely of students. Several colleges that compete at cheerleading competitions offer cheerleading scholarships.

Parachuting

Parachuting is an activity involving a preplanned drop from a height using a deployable parachute.

One type of parachuting is skydiving, which is recreational parachuting, also called sport parachuting.

The history of parachuting is not clear. It's known that Andre-Jacques Garnerin made successful parachute jumps from a hot-air balloon in 1797. The military developed parachuting technology first as a way to save aircrews from emergencies aboard balloons and aircraft in flight, later as a way of delivering soldiers to the battlefield. Early competitions date back to the 1930s, and it became an international sport in 1951.

Today it is performed as a recreational activity and a competitive sport, as well as for the deployment of military personnel Airborne forces and occasionally forest firefighters.

Parachuting has complex skills that can take thousands of jumps to master, but the basics are often fully understood and useful during the first few jumps. There are four basic areas of skill: basic safety, free fall maneuvers, parachute operation, and landing.

Polo

Polo is a team sport played outdoor on horseback in which the objective is to score goals against an opposing team. Riders score by driving a white wooden or plastic ball (size 3–3.5 inches, weight 4.25–4.75 ounces) into the opposing team's goal using a long-handled mallet. Goals are only valid if the scoring rider is mounted. The traditional sport of polo is played outdoors, and each polo team consists of four riders and their mounts. Play occurs in seven-minute periods, called chukkas. The full game is played over eight chukkas; however, depending on league rules, matches can also have four or six chukkas.

The modern indoor variant is called arena polo. In arena polo, there are 3 instead of four players on each team and chukkas are 7 1/2 minutes in length. The playing area is 300' x 150'.

Another modern variant is snow polo, which is played either outdoor or indoor on snow on a frozen ground or ice. Each team generally consists of three players and also the equipment differ from the sport of polo. Other variants include elephant polo, bike polo and Segway polo. These sports are considered as separate sports because of the differences in the composition of teams, equipment, rules, game facilities etc.

Olympic Games

The Olympic Games (often referred to simply as The Olympics or The Games) is an international multi-sport event subdivided into summer and winter sporting events. The summer and winter games are each held every four years (an Olympiad). Until 1992, they were both held in the same year. Since then, they have been separated two years apart.

The original Olympic Games (Greek: Ολυμπιακοί Αγώνες; Olympiakoi Agones) began in 776 BC in Olympia, Greece, and was celebrated until AD 393. Interest in reviving the Olympic Games proper was first shown by the Greek poet and newspaper editor Panagiotis Soutsos in his poem "Dialogue of the Dead" in 1833. Evangelos Zappas sponsored the first modern international Olympic Games in 1859. He paid for the refurbishment of the Panathinaiko Stadium for Games held there in 1870 and 1875. This was noted in newspapers and publications around the world including the London Review, which stated that "the Olympian Games, discontinued for centuries, have recently been revived! Here is strange news indeed ... the classical games of antiquity were revived near Athens".

Swimming

Swimming is movement by humans or animals in water, usually without artificial assistance. Swimming is an activity that is both useful and recreational for many species. Its primary uses are bathing, cooling, travel, fishing and escape. An individual's ability to swim can be judged by speed or stamina.

Animals with lungs have an easier time floating than those without. Almost all mammals can swim by instinct. Bats, kangaroos, moles and sloths can swim, despite their rather strange shapes. The few exceptions include apes and possibly giraffes. Land birds can swim or float for at least some time. Ostriches, cassowaries and tortoises can swim.

The goal of competitive swimming is to be the fastest to swim at a given distance and drop time. Competitive swimming became popular in the nineteenth century, and comprises 34 individual events - 17 male events and 17 female events. Swimming is a popular event at the Summer Olympic Games, where male and female athletes compete in 13 of the recognized events each. Olympic events are held in a 50 meter pool. Competitive swimming's international governing body is FINA (Fédération Internationale de Natation), the International Swimming Federation.

The four competitive strokes are the butterfly, backstroke, breaststroke, and freestyle (front crawl). While "freestyle" and "front crawl" are often used interchangeably, freestyle is the more common name and is used in most all club-swimming or international competitions. A swimmer may actually swim any stroke or combination of strokes in a freestyle race. Swimmers generally choose to swim front crawl in a freestyle event since it is typically the fastest stroke.

Tennis

Tennis is a game played between two players (singles) or between two teams of two players (doubles). Players use a stringed racquet to strike a hollow rubber ball covered with felt (most of the time yellow, but can be any color or even two-tone) over a net into the opponent's court.

Originating in Europe in the late 19th century as "lawn tennis", with its roots going back to the ancient game of real tennis, tennis spread first throughout the English-speaking world, particularly among the upper classes. Tennis is now once again an Olympic sport and is played at all levels of society, by all ages, and in many countries around the world.

Except for the adoption of the tie-breaker in the 1970s, its rules have remained remarkably unchanged since the 1890s. A recent addition to tennis has been the adoption of "instant replay" technology coupled with a point challenge system which allows a player to challenge the official call of a point.

Along with its millions of players, millions of people world-wide follow tennis as a spectator sport, especially the four Grand Slam tournaments: Australian Open, French Open, Wimbledon, and the U.S. Open. The growth of tennis in Eastern Europe and the Far East has been especially notable in recent years.

Tiger Woods

Tiger Woods (born Eldrick Tiger Woods,[1] December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Currently the World No. 1, Woods was the highest paid professional athlete in 2006, having earned an estimated $100 million from winnings and endorsements.

Woods has won 13 professional major golf championships, the second-most of any male player, and 61 PGA Tour events, the fifth-most of all time. He has more career major wins and career PGA Tour wins than any other active golfer. He is the youngest player to achieve the Career Grand Slam, and the youngest and fastest to win 50 tournaments on Tour. Woods has held the number one position in the world rankings for the most consecutive weeks and for the greatest total number of weeks. He has been awarded PGA Player of the Year a record nine times, the Byron Nelson Award for lowest adjusted scoring average a record eight times, and has tied Jack Nicklaus's record of leading the money list in eight different seasons. He has been named Associated Press Male Athlete of the Year four times, a record he shares with Lance Armstrong.

Golf

Golf is a sport in which a player, using several types of clubs, hits a ball into each hole on the golf course in the lowest possible number of strokes. Golf is one of the few ball games that does not use a standardised playing area; rather, the game is played on golf "courses," each one of which has a unique design and typically consists of either 9 or 18 separate holes. Golf is defined in the Rules of Golf as "playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules."

The Royal and Ancient Golf Club of St AndrewsThe first game of golf for which records survive was played at Bruntsfield Links, in Edinburgh, Scotland, in A.D. 1456, recorded in the archives of the Edinburgh Burgess Golfing Society, now The Royal Burgess Golfing Society. Golf has become a worldwide sport, with golf courses in the majority of countries.

Golf competition may be played as stroke play, in which the individual with the lowest number of strokes is declared the winner, or as match play with the winner determined by whichever individual or team posts the lower score on the most individual holes during a complete round. In addition, team events such as fourball have been introduced, and these can be played using either the stroke or matchplay format. Alternative ways to play golf have also been introduced, such as miniature golf and disc golf.

Football

Association football, commonly known as football or soccer, is a team sport played between two teams of eleven players, and it is the most popular sport in the world.[1] It is a ball game played on a rectangular grass or artificial turf field, with a goal at each of the short ends. The object of the game is to score by manoeuvring the ball into the opposing goal. In general play, the goalkeeper is the only player allowed to use their hands or arms to propel the ball; the rest of the team usually use their feet to kick the ball into position, occasionally using their torso or head to intercept a ball in mid air. The team that scores the most goals by the end of the match wins. If the score is tied at the end of the game, either a draw is declared or the game goes into extra time and/or a penalty shootout, depending on the format of the competition.

The modern game was codified in England following the formation of The Football Association, whose 1863 Laws of the Game created the foundations for the way the sport is played today. Football is governed internationally by the Fédération Internationale de Football Association (International Federation of Association Football), commonly known by the acronym FIFA. The most prestigious international football competition is the World Cup, held every four years. This event, the most widely viewed in the world, boasts an audience twice that of the Summer Olympics
