Skiathlon
Competitive cross-country skiing encompasses a variety of race formats and course lengths. Rules of cross-country skiing are sanctioned by the International Ski Federation and by various national organizations. International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games. Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing. It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation. Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment.

FIS Cross-Country World Cup
The FIS Cross-Country World Cup is an annual cross-country skiing competition, arranged by the International Ski Federation (FIS) since 1981. The competition was arranged unofficially between 1973 and 1981, although it received provisional recognition on the 31st FIS Congress, 29–30 April 1977 in Bariloche, Argentina. The first World Cup races were held on 9 January 1982 and were located in Reit im Winkl, West Germany and Klingenthal, East Germany. Bill Koch of the United States and Berit Aunli of Norway were the overall winners in the first season. Rules Competitors attempt to achieve the most points during the season. They compete in two disciplines: Distance and Sprint. Current Distance races are mostly 10 km, 20 km, Skiathlon and 50 km for the men and women. The competitions are held with either individual start or mass start and either classic or free technique. In Sprint races, athletes are organised in heats based on their results in a prologue w ...

Ski Orienteering
Ski orienteering (SkiO) is a cross-country skiing endurance winter racing sport and one of the four orienteering disciplines recognized by the IOF. A successful ski orienteer combines high physical endurance, strength and excellent technical skiing skills with the ability to navigate and make the best route choices while skiing at a high speed. Standard orienteering maps are commonly used, but since 2019, a separate mapping standard ISSkiOM has been produced which recommends a subset of the symbols used in other disciplines. Ski-orienteering maps uses green symbols to indicate trails and tracks and different symbols to indicate their navigability in snow; other symbols indicate whether any roads are snow-covered or clear. Navigation tactics is similar to mountain bike orienteering. Standard skate-skiing equipment is used, along with a map holder attached to the chest. Compared to cross-country skiing, upper body strength is more important because of double-poling needed along nar ...

Schack Carl Rantzau
Schack Carl, '' rigsgreve'' (von) Rantzau or Carl Schack Rantzau-Ascheberg (11 March 1717, Ascheberg estate, Holstein – 21 January 1789, Menerbes, France) was a Holstein-born Danish-Norwegian officer and statesman. He was the commander-in-chief of the Norwegian army in 1766, but lost the position the next year. He is notable for his friendship with Johann Friedrich Struensee and his role in the coup which led to Struensee's fall from power in 1772. Commander-in-chief of the Norwegian army In the 1760s he befriended Claude Louis de Saint-Germain, one of the most powerful men in Denmark-Norway at the time. In 1766 he was promoted to lieutenant general, and on the initiative of Saint-Germain he was sent as Commander-in-chief of the Norwegian army, April 4 of the same year. Norway was not the right place for a man like Rantzau. He found it indescribably boring to live in the country, and in a letter he wrote; ''..this Land of the Devil, where there is not even a tree strong e ...

Performance-enhancing Drugs
Performance-enhancing substances, also known as performance-enhancing drugs (PEDs), are substances that are used to improve any form of activity performance in humans. A well-known example of cheating in sports involves doping in sport, where banned physical performance-enhancing drugs are used by athletes and bodybuilders. Athletic performance-enhancing substances are sometimes referred to as ergogenic aids. Cognitive performance-enhancing drugs, commonly called nootropics, are sometimes used by students to improve academic performance. Performance-enhancing substances are also used by military personnel to enhance combat performance. The use of performance-enhancing drugs spans the categories of legitimate use and substance abuse. Definition The classifications of substances as performance-enhancing substances are not entirely clear-cut and objective. As in other types of categorization, certain prototype performance enhancers are universally classified as such (like anaboli ...

Roller Skiing
Roller skiing is an off-snow equivalent to cross-country skiing. Roller skis have wheels on their ends and are used on a hard surface, to emulate .Bryhn, Rolf and Knut Are Tvedt (eds.): ''Kunnskapsforlagets idrettsleksikon''. (Norwegian Encyclopedia of Sports). Oslo: Kunnskapsforlaget, 1990. The skiing techniques used are very similar to techniques used in cross-country skiing on snow. First created as a summer training exercise, roller skiing grew into a competitive sport in its own right. Annual championships are held in various locations around the world. Most, if not all, national cross-country ski teams around the world roller ski during the off-season for specific physical training simulating winter skiing. In Norway, separate roller ski facilities have been constructed to allow exercise off public roads. History The first roller skis were built in the mid-1930s in Italy and North Europe. In the early 1950s, when cross-country skiing started to evolve to a serious competitio ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ...

Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addi ...

Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ...
