Speed Skiing
Speed skiing is the sport of skiing downhill in a straight line at as high a speed as possible, as timed over a fixed stretch of ski slope. There are two types of contest: breaking an existing speed record or having the fastest run at a given competition. Speed skiers regularly exceed History Speed skiing dates from 1898 with a run by American Tommy Todd, reported at . Official records began with an run by Leo Gasperl in 1932. While training for the 1956 Winter Olympics, American downhiller Ralph Miller is credited with being the first to break , at nearly in August 1955 at Portillo, Chile, a record which held up for fifteen years. In 1978, also at Portillo, American Steve McKinney's record-breaking run of made him the first to break the barrier. It was a demonstration sport at the Albertville 1992 Winter Olympics on the Les Arcs speed skiing course, but was deemed too dangerous after several recorded deaths.

Velocity Challenge - World Cup Speed Skiing - Anyone Care To Try Going 180 Km-hr
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. northbound). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called , being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an ''acceleration''. Constant velocity vs acceleration To have a ''constant velocity'', an object must have a constant speed in a constant direction. Constant direction ...

Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non- vulcanized rubber. Such is the case in products like latex gloves, latex con ...

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". 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, Belarus and Poland. A World Cup circuit is held with events in those countries plus two events in the Thialf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowboard Cross
Snowboard cross, also known as boardercross, is a snowboard competition in which four to six competitors race down a course. Snowboard cross courses are typically quite narrow and include cambered turns, various types of jumps, berms, rollers, drops, steep and flat sections designed to challenge the riders' ability to stay in control while maintaining maximum speed. It is not uncommon for racers to collide with each other mid-race. Snowboard cross courses share common traits with motorcycle motocross courses, hence the similarity between the names of each sport. Competition format is typically a time trial followed by a knock-out tournament. History When Steven Rechtschaffner and partner Greg Stump had run out of ideas for segments for a TV show they were producing for Fox TV called ''Greg Stump's World of Extremes'', Rechtschaffner recalled the race concept that had been in his head for years. Given the need to come up with a final segment, Rechtschaffner, a passionate sn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ski Cross
Ski cross is a skiing competition which incorporates terrain features traditionally found in freestyle skiing with courses which include big-air jumps and high-banked turns. In spite of the fact that it is a timed racing event, it is often considered a type of freestyle skiing. What sets ski cross apart from other alpine skiing disciplines is that it involves more than one skier racing down the course. Any intentional contact with other competitors like grabbing or any other forms of contact meant to give the competitor an advantage leads to disqualification. Ski cross is a part of the FIS Freestyle World Ski Championships, the world championship organized by the FIS for freestyle skiing. First organized in 1986, the world championship is now held every odd year. In 2010 the sport debuted as a part of the Winter Olympic Games and has been contested ever since. It was a part of the Winter X Games until 2012. Overview In a time trial or qualification round, every competitor s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Skiing
Alpine skiing, or downhill skiing, is the pastime of sliding down snow-covered slopes on skis with fixed-heel bindings, unlike other types of skiing ( cross-country, Telemark, or ski jumping), which use skis with free-heel bindings. Whether for recreation or for sport, it is typically practiced at ski resorts, which provide such services as ski lifts, artificial snow making, snow grooming, restaurants, and ski patrol. " Off-piste" skiers—those skiing outside ski area boundaries—may employ snowmobiles, helicopters or snowcats to deliver them to the top of a slope. Back-country skiers may use specialized equipment with a free-heel mode, including 'sticky' skins on the bottoms of the skis to stop them sliding backwards during an ascent, then locking the heel and removing the skins for their descent. Alpine skiing has been an event at the Winter Olympic Games since 1936. A competition corresponding to modern slalom was introduced in Oslo in 1886. Participants and v ...

Ski Pole
Ski poles, also referred to as poles (in North America), sticks (UK), or stocks (Australia), are used by skiers for balance and propulsion. Modern ski poles are most commonly made from aluminum and carbon fiber, though materials such as bamboo are still used. Poles are used in alpine skiing, freestyle skiing (with the exception of aerials), and cross-country skiing. Ski jumpers do not use poles. History , the earliest ski pole was found in Sweden and dates back to 3623 BC, while the earliest depiction of a man with a ski pole was found in Norway in the form of a cave painting, dated at 4000 BC. Early skiers would use this pole for the purposes of balancing, braking, and turning. Alpine societies such as those in Nordic regions or the Altai mountains used their ski poles to hunt as well, giving them spear-like qualities. Skiers began to use two ski poles in 1741. This provided greater balance than one pole could provide and made pushing through the snow easier. Early ski po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
