98-432: A springboard or diving board is used for diving and is a board that is itself a spring , i.e. a linear flex-spring, of the cantilever type. Springboards are commonly fixed by a hinge at one end (so they can be flipped up when not in use), and the other end usually hangs over a swimming pool , with a point midway between the hinge and the end resting on an adjustable fulcrum . Modern springboards are made out of

196-432: A lifeguard is not on duty. It was commetend that "...shallow dives can end up in death or permanent injury." and that in 1988 on lake powell a person "...was left a quadriplegic after diving just 5 feet off a houseboat into the murky lake." Water resistance increases with the speed of entry, so entering the water at high-velocity induces rapid deceleration. Jumping into water from a height of 20 feet (6.1 m) results in

294-518: A platform or springboard , usually while performing acrobatics . Diving is an internationally recognised sport that is part of the Olympic Games . In addition, unstructured and non-competitive diving is a recreational pastime. Competitors possess many of the same characteristics as gymnasts and dancers , including strength, flexibility, kinaesthetic judgement and air awareness. Some professional divers were originally gymnasts or dancers as both

392-492: A wage or salary ). Amateur participation in sport at lower levels is often called "grassroots sport". The popularity of spectator sport as a recreation for non-participants has led to sport becoming a major business in its own right, and this has incentivised a high paying professional sport culture, where high performing participants are rewarded with pay far in excess of average wages, which can run into millions of dollars. Some sports, or individual competitions within

490-693: A ball has crossed the goal line or not. The technology is not compulsory, but was used in the 2014 FIFA World Cup in Brazil, and the 2015 FIFA Women's World Cup in Canada, as well as in the Premier League from 2013–14 , and the Bundesliga from 2015–16 . In the NFL , a referee can ask for a review from the replay booth, or a head coach can issue a challenge to review the play using replays. The final decision rests with

588-461: A definition is provided by the Global Association of International Sports Federations (GAISF), which is the association for all the largest international sports federations (including association football , athletics , cycling , tennis , equestrian sports , and more), and is therefore the de facto representative of international sport. GAISF uses the following criteria, determining that

686-471: A disability have no equivalent in able-bodied sports. Masters sport , senior sport , or veteran sport is an age category of sport, that usually contains age groups of those 35 and older. It may concern unaltered or adapted sport activities, with and without competitions. Competitions The competition element of sport, along with the aesthetic appeal of some sports, result in the popularity of people attending to watch sport being played. This has led to

784-534: A line first. It can also be determined by judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression. Records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news . Sport is also a major source of entertainment for non-participants, with spectator sport drawing large crowds to sport venues , and reaching wider audiences through broadcasting . Sport betting

882-408: A minimum depth of 7 ft 6 in (2.29 m) which proved to be insufficient in the above case. The pool into which Meneely dived was not constructed to the published standards. The standards had changed after the diving board was installed on the non-compliant pool by the homeowner. But the courts held that the pool "was close enough" to the standards to hold NSPI liable. The multimillion-dollar lawsuit

980-508: A person impacting with the water surface at 25 mph (40 km/h). Impacting with the water surface at this velocity is capable of giving a person temporary paralysis of the diaphragm , a compressed spine , broken bones, or concussion . The speed that a diver is travelling at the water surface when they dive from a ten-metre platform is around 35 mph and when a diver hits the water flat from 10 metres they are brought to rest in about 1 ft. The extreme deceleration when hitting

1078-423: A pinwheel, but this is no longer part of competitive synchronised diving. For example, one diver would perform a forward dive and the other an inward dive in the same position, or one would do a reverse and the other a back movement. In these events, the diving would be judged both on the quality of execution and the synchronicity – in timing of take-off and entry, height and forward travel. There are rules governing

1176-408: A range of 0.61 metres (24 inches), and is set by way of a foot wheel that is approximately 0.35 m (14 in) in diameter . To stiffen the spring (as if tightening it), the foot wheel is usually turned counter clockwise. Some may find this counter intuitive, since usually things are tightened by turning clockwise. However, with a little experience, people realize the fulcrum moves in the direction

1274-581: A regular sports season , followed in some cases by playoffs . Sport is generally recognised as system of activities based in physical athleticism or physical dexterity , with major competitions admitting only sports meeting this definition. Some organisations, such as the Council of Europe , preclude activities without any physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports . The International Olympic Committee who oversee

1372-452: A set of towering rocks... ...about 60 feet..." (18.2 metres). He dove into the water doing a "back flip." He never surfaced from the water and was found several days later 120 feet below the surface. The 22-year-old was found to have suffered a broken neck. In competitive diving, FINA takes regulatory steps to ensure that athletes are protected from the inherent dangers of the sport. For example, they impose restrictions according to age on

1470-409: A single person with others being done by hundreds. Most sports take place either in teams or competing as individuals. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner. A number of contests may be arranged in a tournament format, producing a champion . Many sports leagues make an annual champion by arranging games in

1568-425: A single-piece extrusion of aircraft-grade aluminum. The Maxiflex Model B, the board used in all major competitive diving events, is made out of such aluminum, and is heat treated for a yield strength of 340,000 kPa (49,000 psi). The slip-resistant surface of the board is created using an epoxy resin, finished with a laminate of flint silica and alumina in between the top coats of resin. This thermal-cured resin

1666-769: A small number of mind sports, it is not open to admitting any further mind sports. There has been an increase in the application of the term "sport" to a wider set of non-physical challenges such as video games , also called esports (from "electronic sports"), especially due to the large scale of participation and organised competition, but these are not widely recognised by mainstream sports organisations. According to Council of Europe , European Sports Charter, article 2.i, " 'Sport' means all forms of physical activity which, through casual or organised participation, aim at expressing or improving physical fitness and mental well-being, forming social relationships or obtaining results in competition at all levels." There are opposing views on

1764-567: A sport should: They also recognise that sport can be primarily physical (such as rugby or athletics ), primarily mind (such as chess or Go ), predominantly motorised (such as Formula 1 or powerboating ), primarily co-ordination (such as snooker and other cue sports ), or primarily animal-supported (such as equestrian sport ). The inclusion of mind sports within sport definitions has not been universally accepted, leading to legal challenges from governing bodies in regards to being denied funding available to sports. Whilst GAISF recognises

1862-468: A sport, retain a policy of allowing only amateur sport . The Olympic Games started with a principle of amateur competition with those who practised a sport professionally considered to have an unfair advantage over those who practised it merely as a hobby. From 1971, Olympic athletes were allowed to receive compensation and sponsorship, and from 1986, the IOC decided to make all professional athletes eligible for

1960-579: A swimmer named Drake could cover 53 feet (16 m). The English Amateur Swimming Association (at the time called the Swimming Association of Great Britain) first started a " plunging championship " in 1883. The Plunging Championship was discontinued in 1937. Diving into a body of water had also been a method used by gymnasts in Germany and Sweden since the early 19th century. The soft landing allowed for more elaborate gymnastic feats in midair as

2058-402: A very confident dive in front of a very difficult dive to ensure that they will have a good mentality for the difficult dive. Most divers have pre-dive and post-dive rituals that help them either maintain or regain focus. Coaches also play a role in this aspect of the sport. Many divers rely on their coaches to help keep their composure during the meet. In a large meet coaches are rarely allowed on

2156-422: Is a panel of seven, nine, or eleven judges; two or three to mark the execution of one diver, two or three to mark the execution of the other, and the remaining three or five to judge the synchronisation. The execution judges are positioned two on each side of the pool, and they score the diver which is nearer to them. The 2012 London Olympics saw the first use of eleven judges. The score is computed similarly to

2254-437: Is a problem at some national and international sporting contests. Female participation in sports continues to rise alongside the opportunity for involvement and the value of sports for child development and physical fitness . Despite increases in female participation during the last three decades, a gap persists in the enrollment figures between male and female players in sports-related teams. Female players account for 39% of

2352-411: Is aqua-colored to match the water of a clean pool. The spring constant of a springboard is usually adjusted by way of a fulcrum that is located approximately mid way along the springboard. Springboards are usually operated in a linear regime where they approximately obey Hooke's law . When loaded with a diver, the combination of the diver's approximately constant mass , and the constant stiffness of

2450-512: Is common for popular sports to attract large broadcast audiences, leading to rival broadcasters bidding large amounts of money for the rights to show certain events. The football World Cup attracts a global television audience of hundreds of millions; the 2006 final alone attracted an estimated worldwide audience of well over 700 million and the 2011 Cricket World Cup Final attracted an estimated audience of 135 million in India alone. In

2548-456: Is declared failed and scores zero according to a strict reading of the FINA law. But in practice, a re-dive would usually be granted in these circumstances. The global governing body of diving is FINA , which also governs swimming , synchronised swimming , water polo and open water swimming . Almost invariably, at national level, diving shares a governing body with the other aquatic sports. This

2646-445: Is frequently a source of political friction as the committees are naturally dominated by swimming officials who do not necessarily share or understand the concerns of the diving community. Divers often feel, for example, that they do not get adequate support over issues like the provision of facilities. Other areas of concern are the selection of personnel for the specialised Diving committees and for coaching and officiating at events, and

2744-456: Is in some cases severely regulated, and in others integral to the sport. According to A.T. Kearney , a consultancy, the global sporting industry is worth up to $ 620 billion as of 2013. The world's most accessible and practised sport is running , while association football is the most popular spectator sport. The word "sport" comes from the Old French desport meaning " leisure ", with

2842-401: Is multiplied by a degree of difficulty factor, derived from the number and combination of movements attempted. The diver with the highest total score after a sequence of dives is declared the winner. Synchronized diving was adopted as an Olympic sport in 2000. Two divers form a team and perform dives simultaneously. The dives are identical. It used to be possible to dive opposites, also known as

2940-476: Is used in most English dialects to describe the overall concept (e.g. "children taking part in sport"), with "sports" used to describe multiple activities (e.g. "football and rugby are the most popular sports in England"). American English uses "sports" for both terms. The precise definition of what differentiates a sport from other leisure activities varies between sources.

Until recently the GAA continued to ban the playing of football and rugby union at Gaelic venues. This ban, also known as Rule 42, is still enforced, but was modified to allow football and rugby to be played in Croke Park while Lansdowne Road was redeveloped into Aviva Stadium . Until recently, under Rule 21,

3234-477: The Olympic Games recognises both chess and bridge as sports. SportAccord , the international sports federation association, recognises five non-physical sports: chess, bridge, draughts , Go and xiangqi . However, they limit the number of mind games which can be admitted as sports. Sport is usually governed by a set of rules or customs , which serve to ensure fair competition. Winning can be determined by physical events such as scoring goals or crossing

According to the Center for Injury Research and Policy at Nationwide Children's Hospital , the biggest risk for youth sport is death or serious injury including concussion . These risks come from running, basketball, association football, volleyball, gridiron, gymnastics, and ice hockey. Youth sport in

It also resulted in Daley being "...out of action for six days and left him unable to dive off his competition height of 10m for three weeks." It was commented that in 1989 a 22-year-old, who was a "...diver and a member of the Salt Lake Country Club diving team... ...climbed up on

3626-546: The Diver in Paestum , contains a fresco dating to around 500 to 475 BCE that also shows a scene of a person diving into a pool or stream of water from a structure. Although diving has been a popular pastime across the world since ancient times, the first modern diving competitions were held in England in the 1880s. The exact origins of the sport are unclear, though it likely derives from

3724-640: The GAA also banned members of the British security forces and members of the RUC from playing Gaelic games, but the advent of the Good Friday Agreement in 1998 led to the eventual removal of the ban. Nationalism is often evident in the pursuit of sport, or in its reporting: people compete in national teams, or commentators and audiences can adopt a partisan view. On occasion, such tensions can lead to violent confrontation among players or spectators within and beyond

3822-523: The IOC or SportAccord are required to implement a testing programme, looking for a list of banned drugs, with suspensions or bans being placed on participants who test positive for banned substances. Violence in sports involves crossing the line between fair competition and intentional aggressive violence. Athletes, coaches, fans, and parents sometimes unleash violent behaviour on people or property, in misguided shows of loyalty, dominance, anger, or celebration. Rioting or hooliganism by fans in particular

3920-647: The National Graceful Diving Competition, was held there by the Royal Life Saving Society in 1895. The event consisted of standing and running dives from either 15 or 30 feet (4.6 or 9.1 m). It was at this event that the Swedish tradition of fancy diving was introduced to the sport by the athletes Otto Hagborg and C F Mauritzi. They demonstrated their acrobatic techniques from the 10 m diving board at Highgate Pond and stimulated

4018-511: The Olympics use seven-judge panels. For a five-judge panel, the highest and lowest scores are discarded and the middle three are summed and multiplied by the DD. For seven-judge panels, as of the 2012 London Olympics , the two highest scores and two lowest are discarded, leaving three to be summed and multiplied by the DD. (Prior to the London Olympics, the highest and lowest scores were eliminated, and

It is a necessary part of some sports (such as motorsport), and it is used in others to improve performance. Some sports also use it to allow off-field decision making. Sports science is a widespread academic discipline, and can be applied to areas including athlete performance, such as

4214-515: The US is a $ 15 billion industry including equipment up to private coaching. Disabled or adaptive sports are played by people with a disability , including physical and intellectual disabilities . As many of these are based on existing sports modified to meet the needs of people with a disability, they are sometimes referred to as adapted sports . However, not all disabled sports are adapted; several sports that have been specifically created for people with

Many diving accidents occur when divers do not account for submerged objects in the water such as rocks and logs. Because of this many beaches and pools prohibit diving in shallow waters or when

4410-569: The United States scholastic diving is almost always part of the school's swim team. Diving is a separate sport in Olympic and Club Diving. The NCAA will separate diving from swimming in special diving competitions after the swim season is completed. After an incident in Washington in 1993, most US and other pool builders are reluctant to equip a residential swimming pool with a diving springboard so home diving pools are much less common these days. In

Super Bowl Sunday is a de facto national holiday in America; the viewership being so great that in 2015, advertising space was reported as being sold at $ 4.5m for a 30-second slot. Sport can be undertaken on an amateur, professional or semi-professional basis, depending on whether participants are incentivised for participation (usually through payment of

4606-456: The act of diving at the start of swimming races. In the seventeenth century gymnasts moved their equipment to the beaches and "performed acrobatics over the water." The 1904 book Swimming by Ralph Thomas notes English reports of plunging records dating back to at least 1865. The 1877 edition to British Rural Sports by John Henry Walsh makes note of a "Mr. Young" plunging 56 feet (17 m) in 1870, and also states that 25 years prior,

4704-790: The activity will be enjoyed for its own sake. The well-known sentiment by sports journalist Grantland Rice , that it is "not that you won or lost but how you played the game", and the modern Olympic creed expressed by its founder Pierre de Coubertin : "The most important thing... is not winning but taking part" are typical expressions of this sentiment. Key principles of sport include that the result should not be predetermined, and that both sides should have equal opportunity to win. Rules are in place to ensure fair play, but participants can break these rules in order to gain advantage. Participants may cheat in order to unfairly increase their chance of winning, or in order to achieve other advantages such as financial gains. The widespread existence of gambling on

4802-415: The ancient Olympics up to the present century. Industrialisation has brought motorised transportation and increased leisure time , letting people attend and follow spectator sports and participate in athletic activities. These trends continued with the advent of mass media and global communication. Professionalism became prevalent, further adding to the increase in sport's popularity, as sports fans followed

4900-453: The bottom of the foot faces when placed on the foot wheel. Springboards are usually located either 1.0 or 3.0 metres (3 ft 3 in or 9 ft 10 in) above the water surface. It is very seldom that one is mounted at a height other than these two standard heights. Before around 1960, springboards, usually made of wood, were located at heights of either 3 metres (approximately 10 ft), or 6 metres (approximately 20 ft) above

Some feel this was an effective contribution to the eventual demolition of the policy of apartheid, others feel that it may have prolonged and reinforced its worst effects. In the history of Ireland, Gaelic sports were connected with cultural nationalism . Until the mid-20th century a person could have been banned from playing Gaelic football , hurling , or other sports administered by

5194-408: The deck to talk to their athlete so it is common to see coaches using hand gestures or body movements to communicate. There are some American meets which will allow changes of the position of the dive even after the dive has been announced immediately before execution, but these are an exception to the rules generally observed internationally. Generally, NCAA rules allow for dives to be changed while

5292-402: The dive, the conformance of their body to the requirements of the dive, and the amount of splash created by their entry to the water. A possible score out of ten is broken down into three points for the takeoff (meaning the hurdle), three for the flight (the actual dive), and three for the entry (how the diver hits the water), with one more available to give the judges flexibility. The raw score

5390-407: The dive-sheet to be submitted (generally a period ranging from one hour to 24 hours, depending on the rulings made by the event organiser). It is the diver's responsibility to ensure that the dive-sheet is filled in correctly, and also to correct the referee or announcer before the dive if they describe it incorrectly. If a dive is performed which is as submitted but not as (incorrectly) announced, it

5488-414: The diver is on the board, but the diver must request the change directly after the dive is announced. This applies especially in cases where the wrong dive is announced. If the diver pauses during his or her hurdle to ask for a change of dive, it will be declared a ulk (when the diver stops mid-hurdle) and the change of dive will not be permitted. Under FINA law, no dive may be changed after the deadline for

5586-453: The diver's control has caused them to be unable to perform-such as a loud noise). In the Olympics or other highly competitive meets, many divers will have nearly the same list of dives as their competitors. The importance for divers competing at this level is not so much the DD, but how they arrange their list. Once the more difficult rounds of dives begin it is important to lead off with a confident dive to build momentum. They also tend to put

5684-478: The dives. Specifically, if a judge consistently gives low scores for all divers, or consistently gives high scores for the same divers, the judging will yield fair relative results and will cause divers to place in the correct order. However, absolute scores have significance to the individual divers. Besides the obvious instances of setting records, absolute scores are also used for rankings and qualifications for higher level meets. In synchronised diving events, there

5782-510: The diving community, the FINA requirement that international competitors had to be registered with their National Governing Body was a major factor in the abandonment of this ambition a few years later. Since FINA refused to rescind recognition of the ASA as the British governing body for all aquatic sports including diving, this meant that the elite divers had to belong to ASA-affiliated clubs to be eligible for selection to international competition. In

5880-708: The diving events for the 1912 Olympics in Stockholm . In the 1928 Olympics, 'plain' and 'fancy' diving were amalgamated into one event – 'Highboard Diving'. The diving event was first held indoors in the Empire Pool for the 1934 British Empire Games and 1948 Summer Olympics in London . Most diving competitions consist of three disciplines: 1 m and 3 m springboards, and the platform. Competitive athletes are divided by gender, and often by age group. In platform events, competitors are allowed to perform their dives on either

5978-455: The emphasis is on the synchronisation of the divers. The synchronisation scores are based on: The judges may also disqualify the diver for certain violations during the dive, including: To win dive meets, divers create a dive list in advance of the meet. To win the meet the diver must accumulate more points than other divers. Often, simple dives with low DDs will look good to spectators but will not win meets. The competitive diver will attempt

Monuments to the Pharaohs indicate that a number of sports, including swimming and fishing, were well-developed and regulated several thousands of years ago in ancient Egypt . Other Egyptian sports included javelin throwing, high jump, and wrestling. Ancient Persian sports such as

Fancy diving was formally introduced into the championship in 1903. Plain diving was first introduced into the Olympics at the 1904 event . The 1908 Olympics in London added 'fancy diving' and introduced elastic boards rather than fixed platforms. Women were first allowed to participate in

If they fail to perform the dive announced, even if they physically cannot execute the dive announced or if they perform a more difficult dive, they will receive a score of zero. Under exceptional circumstances, a redive may be granted, but these are exceedingly rare (usually for very young divers just learning how to compete, or if some event outside

Since the turn of the 21st century, there has been increasing debate about whether transgender sports people should be able to participate in sport events that conform with their post-transition gender identity . Sportsmanship is an attitude that strives for fair play, courtesy toward teammates and opponents, ethical behaviour and integrity, and grace in victory or defeat. Sportsmanship expresses an aspiration or ethos that

6468-466: The five, seven and a half (generally just called seven), nine, or ten meter towers. In major diving meets, including the Olympic Games and the World Championships, platform diving is from the 10 meter height. Divers have to perform a set number of dives according to established requirements, including somersaults and twists. Divers are judged on whether and how well they completed all aspects of

6566-590: The heights of platforms which divers may compete on. Group D divers have only recently been allowed to compete on the tower. In the past, the age group could compete only springboard, to discourage children from taking on the greater risks of tower diving. Group D tower was introduced to counteract the phenomenon of coaches pushing young divers to compete in higher age categories, thus putting them at even greater risk. However, some divers may safely dive in higher age categories to dive on higher platforms. Usually this occurs when advanced Group C divers wish to compete on

6664-400: The highest DD dives possible with which they can achieve consistent, high scores. If divers are scoring 8 or 9 on most dives, it may be a sign of their extreme skill, or it may be a sign that their dive list is not competitive, and they may lose the meet to a diver with higher DDs and lower scores. In competition, divers must submit their lists beforehand, and once past a deadline (usually when

The increase in technology has also allowed many decisions in sports matches to be taken, or reviewed, off-field, with another official using instant replays to make decisions. In some sports, players can now challenge decisions made by officials. In Association football , goal-line technology makes decisions on whether

In recent years the use of sport to reduce crime , as well as to prevent violent extremism and radicalization , has become more widespread, especially as a tool to improve self-esteem , enhance social bonds and provide participants with a feeling of purpose. There is no high-quality evidence that shows the effectiveness of interventions to increase sports participation of

7448-586: The necessity of competition as a defining element of a sport, with almost all professional sports involving competition, and governing bodies requiring competition as a prerequisite of recognition by the International Olympic Committee (IOC) or GAISF. Other bodies advocate widening the definition of sport to include all physical activity. For instance, the Council of Europe include all forms of physical exercise, including those competed just for fun. In order to widen participation, and reduce

7546-476: The oldest definition in English from around 1300 being "anything humans find amusing or entertaining". Other meanings include gambling and events staged for the purpose of gambling; hunting; and games and diversions, including ones that require exercise. Roget's defines the noun sport as an "activity engaged in for relaxation and amusement" with synonyms including diversion and recreation. The singular term "sport"

7644-448: The pool. The NSPI had specified a minimum depth of 7 ft 6 in (2.29 m) which proved to be insufficient in the above case. The pool into which Meneely dived was not constructed to the published standards. The standards had changed after the diving board was installed on the non-compliant pool by the homeowner. But the courts held that the pool "was close enough" to the standards to hold NSPI liable. The multimillion-dollar lawsuit

7742-565: The referee. A video referee (commonly known as a Television Match Official or TMO) can also use replays to help decision-making in rugby (both league and union ). In international cricket, an umpire can ask the Third umpire for a decision, and the third umpire makes the final decision. Since 2008, a decision review system for players to review decisions has been introduced and used in ICC -run tournaments, and optionally in other matches. Depending on

7840-453: The remaining five scores were multiplied by 3 ⁄ 5 , to allow for comparison to five-judge panels.) The cancelling of scores is used to make it difficult for a single judge to manipulate scores. There is a general misconception about scoring and judging. In serious meets, the absolute score is somewhat meaningless. It is the relative score, not the absolute score that wins meets. Accordingly, good judging implies consistent scoring across

7938-412: The result may be objective or subjective, and corrected with "handicaps" or penalties. In a race, for example, the time to complete the course is an objective measurement. In gymnastics or diving the result is decided by a panel of judges, and therefore subjective. There are many shades of judging between boxing and mixed martial arts, where victory is assigned by judges if neither competitor has lost at

8036-582: The result of sports events can affect the results. A study published in the Proceedings of the National Academy of Sciences showed that when the home team wins the game before the election, the incumbent candidates can increase their share of the vote by 1.5 per cent. A loss had the opposite effect, and the effect is greater for higher-profile teams or unexpected wins and losses. Also, when Washington Redskins win their final game before an election, then

8134-450: The results of sports events creates a motivation for match fixing , where a participant or participants deliberately work to ensure a given outcome rather than simply playing to win. The competitive nature of sport encourages some participants to attempt to enhance their performance through the use of medicines, or through other means such as increasing the volume of blood in their bodies through artificial means . All sports recognised by

8232-405: The scores from other diving events, but has been modified starting with the 2012 London Olympics for the use of the larger judging panels. Each group of judges will have the highest and lowest scores dropped, leaving the middle score for each diver's execution and the three middle scores for synchronisation. The total is then weighted by 3 ⁄ 5 and multiplied by the DD. The result is that

8330-511: The scoring of a dive. Usually a score considers three elements of the dive: the approach, the flight, and the entry. The primary factors affecting the scoring are: Each dive is assigned a degree of difficulty (DD), which is determined from a combination of the moves undertaken, position used, and height. The DD value is multiplied by the scores given by the judges. To reduce the subjectivity of scoring in major meets, panels of five or seven judges are assembled; major international events such as

8428-558: The specific phenomenon of spectator sport. Both amateur and professional sports attract spectators, both in person at the sport venue, and through broadcast media including radio , television and internet broadcast. Both attendance in person and viewing remotely can incur a sometimes substantial charge, such as an entrance ticket, or pay-per-view television broadcast. Sports league and tournament are two common arrangements to organise sport teams or individual athletes into competing against each other continuously or periodically. It

8526-637: The sporting venue, as in the Football War . These trends are seen by many as contrary to the fundamental ethos of sport being carried on for its own sake and for the enjoyment of its participants. Sport and politics collided in the 1972 Olympics in Munich. Masked men entered the hotel of the Israeli Olympic team and killed many of their men. This was known as the Munich massacre . A study of US elections has shown that

8624-448: The sports have similar characteristics to diving. Dmitri Sautin holds the record for most Olympic diving medals won, by winning eight medals in total between 1992 and 2008. In the Tomb of Hunting and Fishing there is a wall painting from around 530 - 500 BCE that shows a person climbing rocks towards a cliff face and a second person diving down the cliff face towards water. The Tomb of

8722-419: The spring(board) result in a resonance frequency that is adjustable by way of the spring constant (set by the fulcrum position). Since the resulting system is in an approximately linear regime, it may be modeled fairly accurately by a second order differential equation . Typically the resonance frequency can be adjusted over a range of a 2:1 or 3:1 ratio . The fulcrum on competitive diving boards travels over

8820-546: The team selection for international competitions. There are sometimes attempts to separate the governing body as a means to resolve these frustrations, but they are rarely successful. For example, in the UK the Great Britain Diving Federation was formed in 1992 with the intention of taking over the governance of Diving from the ASA ( Amateur Swimming Association ). Although it initially received widespread support from

8918-561: The time of Ancient Greece and the military culture and the development of sport in Greece influenced one another considerably. Sport became such a prominent part of their culture that the Greeks created the Olympic Games , which in ancient times were held every four years in a small village in the Peloponnesus called Olympia . Sports have been increasingly organised and regulated from the time of

9016-465: The total participation in US interscholastic athletics. Certain sports are mixed-gender , allowing (or even requiring) men and women to play on the same team. One example of this is Baseball5 , which is the first mixed-gender sport to have been admitted into an Olympic event. Youth sport presents children with opportunities for fun, socialisation, forming peer relationships, physical fitness , and athletic scholarships . Activists for education and

9114-403: The traditional Iranian martial art of Zoorkhaneh had a close connection to warfare skills. Among other sports that originated in ancient Persia are polo and jousting . Various traditional games of India such as Kho kho and Kabbadi have been played for thousands of years. The kabaddi was played potentially as a preparation for hunting. A wide range of sports were already established by

9212-460: The use of video analysis to fine-tune technique, or to equipment, such as improved running shoes or competitive swimwear . Sports engineering emerged as a discipline in 1998 with an increasing focus not just on materials design but also the use of technology in sport, from analytics and big data to wearable technology . In order to control the impact of technology on fair play, governing bodies frequently have specific rules that are set to control

9310-455: The water flat at around 35 mph can cause severe bruising both internal and external, strains to connective tissue securing the organs, possible minor haemorrhaging to lungs and other tissues possibly resulting in a person coughing up blood, a compressed spine , broken bones, or concussion . This is very painful and distressing, but not life-threatening. Tom Daley has described one concussion that occurred to him "I missed my hands before

9408-440: The water. American artist Norman Rockwell 's painting titled Boy on High Dive (1947) shows a boy (Rockwel's youngest son, Peter) peering over a typical wooden springboard of the early 20th century era at the 20 feet height. After an incident in Washington in 1993, most US and other pool builders are reluctant to equip a residential swimming pool with a diving springboard so home diving pools are much less common these days. In

9506-426: Was eventually resolved in 2001 for US$ 6.6 million ($ 8 million after interest was added) in favor of the plaintiff. The NSPI was held to be liable, and was financially strained by the case. It filed twice for Chapter 11 bankruptcy protection and was successfully reorganized into a new swimming pool industry association. Diving (sport) Diving is the sport of jumping or falling into water from

9604-421: Was eventually resolved in 2001 for US$ 6.6 million ($ 8 million after interest was added) in favour of the plaintiff. The NSPI was held to be liable, and was financially strained by the case. It filed twice for Chapter 11 bankruptcy protection and was successfully reorganised into a new swimming pool industry association. It has been commented that for spinal cord injuries related to diving board use in
