Kicksled
The kicksled or spark is a small sled consisting of a chair mounted on a pair of flexible metal runners that extend backward to about twice the chair's length. The sled is propelled by kicking ( or in the Scandinavian languages) the ground by foot. There is a handlebar attached to the top of the chair back. ''Kicksled'' is a direct translation of the Finnish word . Estonian calls it either a 'pushsled' () or 'Finnish sled' (). Some other possible translations are ''kicker'' and ''chair-sled''. Design The typical adult sized sled has runners about long, spaced apart. The steel runner blades are about wide.The handlebars are about above ground. The kicksled is driven forward by the driver standing on one runner, kicking backwards on the ground with the other foot, hence the name. The flexibility of the runners allows the driver to steer the kicksled by twisting the handlebars. One can have a passenger or luggage on the chair seat. The kicksled can also be used as a dog sled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human-powered Vehicles
Human-powered land vehicles are land vehicles propelled over ground by human power, The main ways to support the weight of a human-powered land vehicle and its contents above the ground are rolling contact; sliding contact; intermittent contact; no contact at all as with anything carried; or some combination of the above. The main methods of using human power to propel a land vehicle are some kind of drivetrain; pushing laterally against the ground with a wheel, skate, or ski that simultaneously moves forward; by pushing against the ground directly with an appendage opposite to the direction of travel; or by propeller. Human-powered land vehicles can be propelled by persons riding in the vehicle or by persons walking or running and not supported by the vehicle. Many human-powered land vehicles can also be gravity-powered land vehicles, and vice versa, although some of the latter are quite awkward to use as the former. For example: street luges, gravity racers, and snow boards. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sled
A sled, skid, sledge, or sleigh is a land vehicle that slides across a surface, usually of ice or snow. It is built with either a smooth underside or a separate body supported by two or more smooth, relatively narrow, longitudinal runners similar in principle to skis. This reduces the amount of friction, which helps to carry heavy loads. Some designs are used to transport passengers or cargo across relatively level ground. Others are designed to go downhill for recreation, particularly by children, or competition (compare cross-country skiing with its downhill cousin). Shades of meaning differentiating the three terms often reflect regional variations depending on historical uses and prevailing climate. In British English, ''sledge'' is the general term, and more common than ''sled''. '' Toboggan'' is sometimes used synonymously with ''sledge'' but more often to refer to a particular type of sledge without runners. ''Sleigh'' refers to a moderate to large-sized, usuall ...

Sledding
Sledding, sledging or sleighing is a winter sport typically carried out in a prone or seated position on a vehicle generically known as a sled (North American), a sledge (British), or a sleigh. It is the basis of three Olympic sports: luge, Skeleton (sport), skeleton and bobsledding. When practised on sand, it is known as a form of sandboarding. In Russia sledges are used for maritime activities including fishing and commuting from island to island on ice. History The practical use of sleds is ancient and widespread. They were never developed in areas with inconsistent winter snow cover, as vehicles to transport materials and/or people failed, far more people walked than used wheeled vehicles in icy and snowy conditions. Early designs included hand-pulled sizes as well as larger dog, horse, or ox drawn versions. Early examples of sleds and sledges were found in the Oseberg ship, Oseberg Viking ship excavation. The Toboggan sled is also a traditional form of transport used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nordic Games
The Nordic Games were the first international multi-sport event that focused primarily on winter sports, and were held at varying intervals between 1901 and 1926. It was organized by Sweden's Swedish Central Association for the Promotion of Athletics,SCIF: "Nordiska spelen" (in Swedish), retrieved 1 February 2015 and more specifically by Viktor Balck, a member of that association and one of the five original members of the (IOC). It was, in many ways, a precursor t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridle
A bridle is a piece of equipment used to direct a horse. As defined in the ''Oxford English Dictionary'', the "bridle" includes both the that holds a bit that goes in the mouth of a horse, and the reins that are attached to the bit. It provides additional control and communication through rein pressure (Oxford English Dictionary, n.d., para. 1). Headgear without a bit that uses a noseband to control a horse is called a hackamore, or, in some areas, a bitless bridle. There are many different designs with many different name variations, but all use a noseband that is designed to exert pressure on sensitive areas of the animal's face to provide direction and control. The bridle was devised by Indo-European herders of the Pontic-Caspian steppes to control horses between 3000 BC and 2000 BC. Parts The bridle consists of the following elements: * Crownpiece: The crownpiece, headstall (US) or headpiece (UK) goes over the horse's head just behind the animal's ears, at the pol ...

Speed Skating
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 International Skating Union (ISU), the governing body of competitive ice sports, refers to long track as "speed skating" and short track as "short track skating". Long track speed skating takes place on a 400m ice track, while short track takes place on a 111m track. An international federation was founded in 1892, the first for any winter sport. The sport enjoys large popularity in the Netherlands, Norway and South Korea. There are top international rinks in a number of other countries, including Canada, the United States, Germany, Italy, Japan, Russia, Kazakhstan, China, Bel ...

Racing On Kickspark
In sports, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in "Pointe du Raz" (the most western point of France, in Brittany), and "''raz-de-marée''" (tsunami). The word ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Nature
''La Nature'' (English: ''Nature'') was a French language magazine aimed at the popularization of science established in 1873 by French scientist and adventurer Gaston Tissandier. The magazine also received an enormous amount of time, effort, and contributions from his brother, Albert Tissandier. Evolution The beginning From 1873 to 1914, each year's volume started at the beginning of December. The second six-month period began with the first issue in June. Starting in 1915, ''La Natures publishing year was brought in sync with the calendar year. A weekly magazine until the 1920s, it became first fortnightly and then monthly in 1948. Second World War During the Second World War, ''La Nature'' was published only erratically. The first interruption in publishing lasted from September 15 to December 15, 1939, with only an additional six issues published during all of 1940. 1941 saw 12 issues published, on the 15th of each month. There were other suspensions in publication, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
