Roller hockey is a form of hockey played on a dry surface using wheeled skates. Most professional inline hockey games take place on an indoor or outdoor sport court. Otherwise, any dry surface can be used to host a game, typically a roller rink, macadam, or cement. The term "Roller hockey" is often used interchangeably to refer to three variant forms chiefly differentiated by the equipment used. There is traditional "Roller hockey", played with quad skates and a ball, "Inline hockey", played with inline skates and puck and "Skater hockey", played with quad skates or inline skates and plastic ball. Combined, roller hockey is played in nearly 60 countries worldwide.
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water, on ice (iceboat) or on land over a chosen course, which is often part of a larger plan of navigation.
Speed skating is a competitive form of ice skating in which the competitors race each other in travelling a certain distance on skates. Types of speed skating are long track speed skating, short track speed skating, and marathon speed skating. In the Olympic Games, long-track speed skating is usually referred to as just "speed skating", while short-track speed skating is known as "short track". The ISU, the governing body of both ice sports, refers to long track as "speed skating" and short track as "short track skating".
Roller skating is the traveling on surfaces with roller skates. It is a form of recreational activity as well as a sport, and can also be a form of transportation. In fact, as the United States readied for World War II, the government entertained the notion to add roller skates as essential equipment to move infantry around Europe to save gas. Skates generally come in three basic varieties: quad roller skates, inline skates or blades and tri-skates, though some have experimented with a single-wheeled "quintessence skate" or other variations on the basic skate design. In America, this hobby was most popular first between 1935 and the early 1960s and then in the 1970s, when polyurethane wheels were created and disco music oriented roller rinks were the rage and then again in the 1990s when in-line outdoor roller skating, thanks to the improvement made to inline roller skates in 1981 by Scott Olson, took hold.
A hockey stick is a piece of sport equipment used by the players in all the forms of hockey to move the ball or puck either to push, pull, hit, strike, flick, steer, launch or stop the ball/puck during play with the objective being to move the ball/puck around the playing area using the stick.
Skating involves any sports or recreational activity which consists of traveling on surfaces or on ice using skates.
An ice boat is a boat or purpose-built framework similar in functional design to a sail boat but fitted with skis or runners (skates) and designed to run over ice instead of through (liquid) water. Ice yachting is the sport of sailing and racing iceboats. Sail-able ice is known in the sport as "hard water" versus sailing on liquid or "soft" water. A related sport, land sailing, utilizes a configuration with an iceboat-like fuselage or frame equipped with wheels instead of runners. Iceboats commonly used for racing are usually only for one person, but several classes of two-seat and multiple-seat iceboats are more or less common. On some boats, a "side car" can be fitted to take others along for a ride.
A windsport is any type of sport which involves wind-power, often involving a non-rigid airfoil such as a sail or a power kite. The activities can be land-based, on snow, on ice or on water. Windsport activity may be regulated in some countries by aviation/maritime authorities if they are likely to interfere with other activities. Local authorities may also regulate activity in certain areas, especially on crowded beaches and parks.
Roller skates are shoes, or bindings that fit onto shoes, that are worn to enable the wearer to roll along on wheels. The first roller skate was effectively an ice skate with wheels replacing the blade. Later the "quad" style of roller skate became more popular consisting of four wheels arranged in the same configuration as a typical car.
Tour skating is recreational long distance ice skating on natural ice. It is particularly popular in the Netherlands, the Nordic countries, and Alaska. While Nordic skating usually involves tours over open ice on marshes, lakes, rivers, or sea, in the Netherlands skaters follow marked routes on frozen canals and connected lakes. Consequently there are differences in equipment and skating styles between these two regions. Alaskans often include winter camping on longer journeys of a hundred miles or more.
Roller in-line hockey, or inline hockey is a variant of hockey played on a hard, smooth surface, with players using inline skates to move and hockey sticks to shoot a hard, plastic puck into their opponent's goal to score points. There are five players including the goalkeeper from each team on the rink at a time, while teams normally consist of 16 players.
Artistic roller skating is a sport similar to figure skating but where competitors wear roller skates instead of ice skates. Within artistic roller skating, there are several disciplines:
Sporting equipment, also called sporting goods, has various forms depending on the sport, but it is essential to complete the sport. The equipment ranges from balls, to nets, and to protective gear like helmets. Sporting equipment can be used as protective gear or as tool used to help the athletes play the sport. Over time, sporting equipment has evolved because sports have started to require more protective gear to prevent injuries. Sporting equipment may be found in any department store.
A kitewing is a wing-shaped sail designed to use wind power to provide speed and lift to riders in outdoor environments. It can be used on a number of different surfaces when paired with the appropriate vehicle:
Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack that is increasingly smaller. At the same time, such vehicles are subject to relatively low forward resistance, compared with traditional sailing craft. As a result, such vehicles are often capable of speeds exceeding that of the wind.
