Cluster ballooning

Cluster ballooning is a form of ballooning where a harness attaches a balloonist to a cluster of helium-inflated rubber balloons. Unlike traditional hot-air balloons, where a single large balloon is equipped with vents enabling altitude control, cluster balloons are multiple, small, readily available and individually sealed balloons. To control flight, arrest a climb or initiate a descent, the pilot incrementally jettisons or deflates balloons. Ballast, e.g., bottled water, can also be jettisoned to facilitate ascent.

Competitive dancing

Competitive dance is a popular, widespread sport in which competitors perform dances in any of several permitted dance styles—such as acro, ballet, contemporary, jazz, hip-hop, lyrical, modern, musical theatre, tap, and improv—before a common group of judges. This is in contrast with other activities that involve competition among dancers based on purpose, or specific dance styles or genres, such as pom squad and dancesport (competitive ballroom dance). Competitive dancers must be physically fit because even short dances can be physically demanding. Dancers must continuously train to maintain and improve their technique, balance skills, strength and flexibility. Dance studios typically advise their students to avoid activities that put them at risk for injury or illness, especially while attending competitions. (Source: Wikipedia.org, CC BY-SA)

Cricket

Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a 22-yard (20-metre) pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are 'out'). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches. They communicate with two off-field scorers who record the match's statistical information. (Source: Wikipedia.org, CC BY-SA)

Cycle polo

Cycle polo, bicycle polo, or bike polo (polo-vélo in French; Radpolo in German) is a team sport, similar to traditional polo, except that bicycles are used instead of horses. There are two versions of the sport: grass and Hardcourt Bike Polo. The hardcourt game saw a sharp spike in interest in the first decade of the 21st century and new teams are sprouting up across the world in China, Canada, Ireland, Switzerland, France, India, Germany, Pakistan, Ukraine, Russia, Malaysia, Sri Lanka, Indonesia, Hungary, Australia, New Zealand, Sweden, England, Scotland, Argentina, Italy, Spain, USA, Poland, Croatia, Slovenia, Lithuania, Nepal, Brazil and Cuba.

Cyclocross

Cyclo-cross (cyclocross, CX, cyclo-X or 'cross) is a form of bicycle racing. Races typically take place in the autumn and winter (the international or 'World Cup' season is October–February), and consist of many laps of a short (2.5–3.5 km or 1.5–2 mile) course featuring pavement, wooded trails, grass, steep hills and obstacles requiring the rider to quickly dismount, carry the bike while navigating the obstruction and remount. Races for senior categories are generally between 40 minutes and an hour long, with the distance varying depending on the ground conditions. The sport is strongest in the traditional road cycling countries such as Belgium (Flanders in particular), France and the Netherlands. (Source: Wikipedia.org, CC BY-SA)

Darts

Darts or dart-throwing is a competitive sport in which two or more players bare-handedly throw small sharp-pointed missiles known as darts at a round target known as a dartboard. Points can be scored by hitting specific marked areas of the board, though unlike in sports such as archery, these areas are distributed all across the board and do not follow a principle of points increasing towards the centre of the board. Though a number of similar games using various boards and rules exist, the term 'darts' usually now refers to a standardised game involving a specific board design and set of rules. Darts is both a professional shooting sport and a traditional pub game. Darts is commonly played in the United Kingdom and the Republic of Ireland, and recreationally enjoyed around the world.

Disc dog

Disc dog (commonly called Frisbee dog) is a dog sport. In disc dog competitions, dogs and their human flying disc throwers compete in events such as distance catching and somewhat choreographed freestyle catching. The sport celebrates the bond between handler and dog, by allowing them to work together. The term 'disc' is preferred because 'Frisbee' is a trademark (held by Wham-O) for a brand of flying disc. (Source: Wikipedia.org, CC BY-SA)

Disc golf

Disc golf is a flying disc sport in which players throw a disc at a target; it is played using rules similar to golf. Most disc golf discs are made out of polypropylene plastic, otherwise known as polypropene, which is a thermoplastic polymer resin used in a wide variety of applications. Discs are also made using a variety of other plastic types that are heated and molded into individual discs. The sport is usually played on a course with 9 or 18 holes (baskets). Players complete a hole by throwing a disc from a tee pad or area toward a target, known as a basket, throwing again from where the previous throw landed, until the basket is reached. The baskets are formed by wire with hanging chains above the basket, designed to catch the incoming discs, which then fall into the basket, for a score. Usually, the number of throws a player uses to reach each basket is tallied (often in relation to par), and players seek to complete each hole in the lowest number of total throws. Par is the number of strokes an expert player is expected to make for a given hole or a group of holes (usually 9 or 18). (Source: Wikipedia.org, CC BY-SA)

Discus throw

The discus throw (pronunciation), also known as disc throw, is a track and field event in which an athlete throws a heavy disc—called a discus—in an attempt to mark a farther distance than their competitors. It is an ancient sport, as demonstrated by the fifth-century-BC Myron statue Discobolus. Although not part of the modern pentathlon, it was one of the events of the ancient Greek pentathlon, which can be dated back to at least 708 BC, and it is part of the modern decathlon.

Dodgeball

Dodgeball is a team sport in which players on two teams try to throw balls and hit opponents, while avoiding being hit themselves. The objective of each team is to eliminate all members of the opposing team by hitting them with thrown balls, catching a ball thrown by an opponent, or inducing an opponent to commit a violation, such as stepping outside the court. The sport is mostly played in schools under varying rules, and also formally as an international sport, under rules that vary among international governing bodies, such as the World Dodgeball Federation (WDBF), which runs the Dodgeball World Championship and the World Dodgeball Association (WDA). USA Dodgeball is the governing entity for dodgeball in the United States, with member leagues and clubs across the nation. (Source: Wikipedia.org, CC BY-SA)

Dressage

Dressage (/ˈdrɛsɑːʒ/ or /drɪˈsɑːʒ/; a French term, most commonly translated to mean 'training') is a form of horse riding performed in exhibition and competition, as well as an art sometimes pursued solely for the sake of mastery. As an equestrian sport defined by the International Equestrian Federation, dressage is described as 'the highest expression of horse training' where 'horse and rider are expected to perform from memory a series of predetermined movements.' Competitions are held at all levels from amateur to the Olympic Games and World Equestrian Games. Its fundamental purpose is to develop, through standardized progressive training methods, a horse's natural athletic ability and willingness to perform, thereby maximizing its potential as a riding horse. At the peak of a dressage horse's gymnastic development, the horse responds smoothly to a skilled rider's minimal aids. The rider is relaxed and appears effort-free while the horse willingly performs the requested movement. (Source: Wikipedia.org, CC BY-SA)

Duathlon

Duathlon is an athletic event that consists of a running leg, followed by a cycling leg and then another running leg in a format similar to triathlons. The International Triathlon Union governs the sport internationally. In this variation, the cycling and running segments need to be undertaken simultaneously by a team consisting of a predetermined number of individuals. Only one of the team members is running while all others are cycling. All the members of a team must be together at any given point of time but exchanging the tasks of running and cycling amongst the team members themselves is permitted.

Field hockey

Field hockey is a team sport structured in standard hockey format, in which each team plays with ten outfield players and a goalkeeper. Teams must drive a round hockey ball by hitting it with a hockey stick towards the rival team's shooting circle and then into the goal. The match is won by the team that scores the most goals. Matches are played on grass, watered turf, artificial turf, synthetic field, or indoor boarded surface. The stick is made of wood, carbon fibre, fibreglass, or a combination of carbon fibre and fibreglass in different quantities. The stick has two sides; one rounded and one flat; only the flat face of the stick is allowed to progress the ball. During play, goalkeepers are the only players allowed to touch the ball with any part of their body. A player's hand is considered part of the stick if holding the stick. If the ball is 'played' with the rounded part of the stick (i.e. deliberately stopped or hit), it will result in a penalty (accidental touches are not an offense if they do not materially affect play). Goalkeepers often have a different design of stick; they also cannot play the ball with the round side of their stick. (Source: Wikipedia.org, CC BY-SA)

Figure skating

Figure skating is a sport in which individuals, pairs, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, when contested at the 1908 Olympics in London. The Olympic disciplines are men's singles, women's singles, pair skating, and ice dance; the four individual disciplines are also combined into a team event, first included in the Winter Olympics in 2014. The non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs (the short program and the free skate), which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves.

Finswimming

Finswimming is an underwater sport consisting of four techniques involving swimming with the use of fins either on the water's surface using a snorkel with either monofins or bifins or underwater with monofin either by holding one's breath or using open circuit scuba diving equipment. Events exist over distances similar to swimming competitions for both swimming pool and open water venues. Competition at world and continental level is organised by the Confédération Mondiale des Activités Subaquatiques (CMAS). The sport's first world championship was held in 1976. It also has been featured at the World Games as a trend sport since 1981 and was demonstrated at the 2015 European Games in June 2015. (Source: Wikipedia.org, CC BY-SA)

Fishing

Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations (fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. (Source: Wikipedia.org, CC BY-SA)

Floor

In gymnastics, the floor is a specially prepared exercise surface, which is considered an apparatus. It is used by both male and female gymnasts. The gymnastics event performed on the floor is called floor exercise. The English abbreviation for the event in gymnastics scoring is FX. A spring floor is used in all of gymnastics to provide more bounce, and also help prevent potential injuries to lower extremity joints of gymnasts due to the nature of the apparatus, which includes the repeated pounding required to train it. Cheerleading also uses spring floors for practice. The sprung floor used for indoor athletics, however, is designed to reduce bounce. (Source: Wikipedia.org, CC BY-SA)

Flying disc freestyle

Flying disc freestyle, also known as freestyle Frisbee in reference to the trademarked brand name, is a sport and performing art characterized by creative, acrobatic, and athletic maneuvers with a flying disc. Freestyle is performed individually or more commonly in groups, both competitively and recreationally. The Freestyle Players Association (FPA) is the governing body of freestyle, 'dedicated to the growth of freestyle disc play as a lifetime recreation and competitive sport. The organization is involved in international tournaments and rankings as well as education grants and promotional activities. Every year, the FPA holds a world championship with divisions in Open Pairs, Mixed Pairs, Open Co-op, and Women's Pairs. Competitive freestyle is usually judged on execution, difficulty, and artistic impression by a panel of players. (Source: Wikipedia.org, CC BY-SA)

Football

Football is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word football normally means the form of football that is the most popular where the word is used. Sports commonly called football include association football (known as soccer in North America and Australia); gridiron football (specifically American football or Canadian football); Australian rules football; rugby union and rugby league; and Gaelic football. These various forms of football share to varying extent common origins and are known as 'football codes'. (Source: Wikipedia.org, CC BY-SA)

Formula racing

Formula racing (known as open-wheel racing in North America) is any of several forms of open-wheeled single-seater motorsport. The origin of the term lies in the nomenclature that was adopted by the FIA for all of its post-World War II single-seater regulations, or formulae. The best known of these formulae are Formula One, Formula E, Formula Two, Formula Three, regional Formula Three and Formula Four. Common usage of 'formula racing' encompasses other single-seater series, including the GP2 Series, which replaced Formula 3000 (which had itself been the effective replacement for Formula Two).

Freestyle bmx

Freestyle BMX is bicycle motocross stunt riding on BMX bikes. It is an extreme sport descended from BMX racing that consists of five disciplines: street, park, vert, trails, and flatland. In June 2017, the International Olympic Committee announced that freestyle park was to be added as an Olympic event to the 2020 Summer Olympics. (Source: Wikipedia.org, CC BY-SA)

Freestyle football

Freestyle football is the art of juggling a football using any part of the body, excluding the elbows to the hands. It combines football tricks, dance, acrobatics and music to entertain onlookers and compete with opponents. The official governing body for this sport is known as the World Freestyle Football Association (WFFA). (Source: Wikipedia.org, CC BY-SA)

Freestyle motocross

Freestyle motocross (also known as FMX) is a variation on the sport of motocross in which motorcycle riders attempt to impress judges with jumps and stunts. The backflip was once considered all but impossible, the 'holy grail of FMX'. Freestyle riders began contemplating it after the 1998 film 'Children of a Metal God' showed riders attempting the trick into water. Also it had been done many times on BMX bikes, and FMX riders were using tricks from BMX riders, such as when Travis Pastrana performed an Indian Air, originally from Mat Hoffman, a BMXer.

Futsal

Futsal is an association football-based game played on a hard court smaller than a football pitch, and mainly indoors. It has similarities to five-a-side football and indoor soccer. Futsal is played between two teams of five players each, one of whom is the goalkeeper. Unlimited substitutions are permitted. Unlike some other forms of indoor soccer, it is played on a hard court surface marked by lines; walls or boards are not used. It is played with a smaller, harder, lower-bounce ball than football. The surface, ball and rules favour ball control and passing in small spaces. The game emphasizes control, improvisation, creativity and technique. (Source: Wikipedia.org, CC BY-SA)

Gliding

Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word soaring is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than 1,000 kilometres (621 mi) are achieved.

Golf

Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 18 or 9 holes, regions of terrain that each contain a cup, the hole that receives the ball. Each hole on a course contains a teeing ground to start from, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various hazards such as water, rocks, or sand-filled bunkers. Each hole on a course is unique in its specific layout. (Source: Wikipedia.org, CC BY-SA)

Gymnastics

Gymnastics is a type of sport that includes physical exercises requiring balance, strength, flexibility, agility, coordination, dedication and endurance. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, back, chest, and abdominal muscle groups. Gymnastics evolved from exercises used by the ancient Greeks that included skills for mounting and dismounting a horse, and from circus performance skills. (Source: Wikipedia.org, CC BY-SA)

Hammer throw

The hammer throw is one of the four throwing events in regular track and field competitions, along with the discus throw, shot put and javelin. The 'hammer' used in this sport is not like any of the tools also called by that name. It consists of a metal ball attached by a steel wire to a grip. The size of the ball varies between men's and women's competitions. (Source: Wikipedia.org, CC BY-SA)

Handball

Handball (also known as team handball, European handball or Olympic handball) is a team sport in which two teams of seven players each (six outcourt players and a goalkeeper) pass a ball using their hands with the aim of throwing it into the goal of the other team. A standard match consists of two periods of 30 minutes, and the team that scores more goals wins. Modern handball is played on a court of 40 by 20 metres (131 by 66 ft), with a goal in the middle of each end. The goals are surrounded by a 6-metre (20 ft) zone where only the defending goalkeeper is allowed; goals must be scored by throwing the ball from outside the zone or while 'diving' into it. The sport is usually played indoors, but outdoor variants exist in the forms of field handball, Czech handball (which were more common in the past) and beach handball. The game is fast and high-scoring: professional teams now typically score between 20 and 35 goals each, though lower scores were not uncommon until a few decades ago. Body contact is permitted for the defenders trying to stop the attackers from approaching the goal. No protective equipment is mandated, but players may wear soft protective bands, pads and mouth guards. (Source: Wikipedia.org, CC BY-SA)

Hang gliding

Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to soar for hours, gain thousands of feet of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the safety benefits of being instructed is highly recommended and indeed a mandatory requirement in many countries. (Source: Wikipedia.org, CC BY-SA)

High jump

The high jump is a track and field event in which competitors must jump unaided over a horizontal bar placed at measured heights without dislodging it. In its modern, most-practiced format, a bar is placed between two standards with a crash mat for landing. Since ancient times, competitors have introduced increasingly effective techniques to arrive at the current form, and the current universally preferred method is the Fosbury Flop, in which athletes run towards the bar and leap head first with their back to the bar. (Source: Wikipedia.org, CC BY-SA)

Hopper balloon

A hopper balloon (simply hopper) is a small, one-person hot air balloon. Unlike a conventional hot air balloon where people ride inside a basket, there is no basket on a hopper balloon. Instead, the hopper pilot usually sits on a seat or wears a harness similar to a parachute harness. Hoppers are typically flown for recreation. These aircraft are sometimes called 'cloud hoppers' or 'cloudhoppers'. However, these terms formally refer to the products of a particular manufacturer, specifically Lindstrand Balloons. Nonetheless, 'cloudhopper' is used by many people as a genericized trademark, which refers to all craft of this general type. Most hopper balloons have envelopes that range in volume from 14,000 to 35,000 cubic feet (400 to 990 m3) and have a maximum flight duration of 1 to 1.5 hours. The two principal commercial balloon manufacturers today offering hopper balloons for sale are Cameron Balloons and Lindstrand Balloons. Most other hopper balloons are experimental aircraft designed and built by amateur constructors. (Source: Wikipedia.org, CC BY-SA)

Horizontal bar

The horizontal bar, also known as the high bar, is an apparatus used by male gymnasts in artistic gymnastics. It traditionally consists of a cylindrical metal (typically steel) bar that is rigidly held above and parallel to the floor by a system of cables and stiff vertical supports. Gymnasts typically wear suede leather grips while performing on the bar. Current elite-level competition uses a stainless steel core rail. The gymnastics elements performed on the horizontal bar are regulated by a Code of Points. A bar routine, which is a sequence of several bar skills, usually includes giants with various grips (overgrip, undergrip, dorsal grip, mixed grip), in-bar work, turns, release and regrasp skills, and a dismount. The horizontal bar is often considered one of the most exciting gymnastics events due to the power exhibited by gymnasts during giant swings and spectacular aerial releases and dismounts that often include multiple flips or twists and, in some cases, airborne travel over the bar. (Source: Wikipedia.org, CC BY-SA)

Horse racing

Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. (Source: Wikipedia.org, CC BY-SA)

Hunting

Hunting is the human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products (fur/hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to eliminate pests and nuisance animals that damage crops/livestock/poultry or spread diseases (see varminting), for trade/tourism (see safari), or for ecological conservation against overpopulation and invasive species. Recreationally hunted species are generally referred to as the game, and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; an experienced hunter who helps organize a hunt and/or manage the game reserve is known as a gamekeeper. (Source: Wikipedia.org, CC BY-SA)

Hurdling

Hurdling is the act of jumping over an obstacle at a high speed or in a sprint. In the early 19th century, hurdlers ran at and jumped over each hurdle (sometimes known as 'burgles'), landing on both feet and checking their forward motion. Today, the dominant step patterns are the 3-step for high hurdles, 7-step for low hurdles, and 15-step for intermediate hurdles. Hurdling is a highly specialized form of obstacle racing, and is part of the sport of athletics. In hurdling events, barriers known as hurdles are set at precisely measured heights and distances. Each athlete must pass over the hurdles; passing under or intentionally knocking over hurdles will result in disqualification. (Source: Wikipedia.org, CC BY-SA)

Ice climbing

Ice climbing is the activity of ascending inclined ice formations. Usually, ice climbing refers to roped and protected climbing of features such as icefalls, frozen waterfalls, and cliffs and rock slabs covered with ice refrozen from flows of water. For the purposes of climbing, ice can be broadly divided into two spheres, alpine ice and water ice. Alpine ice is found in a mountain environment, usually requires an approach to reach, and is often climbed in an attempt to summit a mountain. Water ice is usually found on a cliff or other outcropping beneath water flows. Alpine ice is frozen precipitation whereas water ice is a frozen liquid flow of water. Most alpine ice is generally one component of a longer route and often less technical, having more in common with standard glacier travel, while water ice is selected largely for its technical challenge. Technical grade is, however, independent of ice type and both types of ice vary greatly in consistency according to weather conditions. Ice can be soft, hard, brittle or tough. (Source: Wikipedia.org, CC BY-SA)

Ice fishing

Ice fishing is the practice of catching fish with lines and fish hooks or spears through an opening in the ice on a frozen body of water. Ice fishers may fish in the open or in heated enclosures, some with bunks and amenities. Ice fishing gear is highly specialized. An ice saw, ice auger or chisel is used to cut a circular or rectangular hole in the ice. The size of the hole depends on the type of fish sought, generally suggested is 8 inches (20 cm). Power augers are sometimes used. If these tools are not available, an axe may be used to chop the hole. A skimmer, a large metal spoon with holes in it, is used to remove new ice as it forms and to clear slush left from making the hole. During colder periods most ice anglers choose to carry a heater of some type. The heater is not only for warmth but also for keeping an angler's fishing hole from freezing. When temperatures fall to -20 °F (-29 °C) or colder it becomes very hard to keep a fishing hole open. (Source: Wikipedia.org, CC BY-SA)

Ice hockey

Ice hockey (or simply hockey) is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. In ice hockey, two opposing teams use ice hockey sticks to control, advance and shoot a closed, vulcanized, rubber disc called a 'puck' into the other team's goal. Each goal is worth one point. The team which scores the most goals is declared the winner. In a formal game, each team has six skaters on the ice at a time, barring any penalties, one of whom is the goaltender. Ice hockey is a full contact sport. Ice hockey is one of the sports featured in the Winter Olympics while its premiere international amateur competition, the IIHF World Championships, are governed by the International Ice Hockey Federation (IIHF) for both men's and women's competitions. Ice hockey is also played as a professional sport. (Source: Wikipedia.org, CC BY-SA)

Ice yachting

An iceboat (occasionally spelled ice boat or traditionally called an ice yacht) is a recreational or competition sailing craft supported on metal runners for traveling over ice. One of the runners is steerable. Originally, such craft were boats with a support structure, riding on the runners and steered with a rear blade, as with a conventional rudder. As iceboats evolved, the structure became a frame with a seat or cockpit for the iceboat sailor, resting on runners. Steering was shifted to the front. Because of their low resistance to forward motion over ice, iceboats are capable of speeds exceeding 60 miles per hour (100 km/h). Because of their speed, iceboats are used both for recreation and for racing. Racing craft typically carry one person. A related activity, land sailing, employs sailing craft similar to iceboats, but riding on wheels instead of runners. (Source: Wikipedia.org, CC BY-SA)
