Parallel Turn
The parallel turn in alpine skiing is a method for turning which rolls the ski onto one edge, allowing it to bend into an arc. Thus bent, the ski follows the turn without sliding. It contrasts with earlier techniques such as the stem Christie, which slides the ski outward from the body ("stemming") to generate sideways force. Parallel turns generate much less friction and are more efficient both in maintaining speed and minimizing skier effort. The parallel turn was invented in the 1930s by Austrian ski racer Anton Seelos from Seefeld in Tirol.Nick Howe''The Blitz Form Kitz'' Skiing Heritage 1/1997 p.17. Parallel turns require solid contact from the skier's lower leg to the ski to rotate it on-edge. This was difficult to achieve with early ski equipment, limiting the technique to the high performance realm of racing. The introduction of composite skis, metal edges, releasable clamping bindings, and stiff plastic boots combined to allow parallel turns even on beginner equipment ...

Alpine Skiing
Alpine skiing, or downhill skiing, is the pastime of sliding down snow-covered slopes on skis with fixed-heel Ski binding, bindings, unlike other types of skiing (Cross-country skiing, cross-country, Telemark skiing, 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. "Piste, Off-piste" skiers—those skiing outside ski area boundaries—may employ snowmobiles, heliskiing, helicopters or Snowcat, snowcats to deliver them to the top of a slope. Back country skiing, Back-country skiers may use specialized equipment with a free-heel mode, including 'sticky' Ski skins, 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 ski racing has been held at the Alpine skiing at the Win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Stem Christie
The stem christie or wedge christie, is a type of skiing turn that originated in the mid-1800s in Norway and lasted until the late 1960s. It comprises three steps: 1) forming a wedge by rotating the tail of one ski outwards at an angle to the direction of movement, initiating a change in direction opposite to the stemmed ski, 2) bringing the other ski parallel to the wedged ski, and 3) completing the turn with both skis parallel as they carve an arc, sliding sideways together. History The stem Christiana was developed by Sondre Norheim in the mid-1800s. Norheim was a Norwegian skier and inventor whose innovations included early ski heel bindings that facilitated turning and jumping, and method for turning that included the basic stem, the Christiana, stem Christiana and parallel turns. The term derives from turns employed by Norwegian jumpers in Oslo, Norway—then called " Christiania"—which was later shortened to "christie". This specific type of turn was promoted in the f ...

Austria
Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine Federal states of Austria, states, of which the capital Vienna is the List of largest cities in Austria, most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has Austrians, a population of around 9 million. The area of today's Austria has been inhabited since at least the Paleolithic, Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Roman Empire, Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Western Roman Empire, Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

Seefeld In Tirol
Seefeld in Tirol is an old farming village, now a major tourist resort, in Innsbruck-Land District in the Austrian state of Tyrol (state), Tyrol with a local population of 3,312 (as of 1 January 2013). The village is located about northwest of Innsbruck on a plateau between the Wetterstein mountains and the Karwendel on a historic road from Mittenwald to Innsbruck that has been important since the Middle Ages. It was first mentioned in 1022 and since the 14th century has been a pilgrimage church, pilgrimage site, benefiting not only from the visit of numerous pilgrims but also from its stacking rights as a trading station between Augsburg and the Republic of Venice, Venice. Also since the 14th century, Tyrolean shale oil has been extracted in the area. Seefeld was a popular holiday resort even before 1900 and, since the 1930s, has been a well known winter sports area, winter sports centres and amongst the most popular tourist resorts in Austria. The municipality, which has been the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sidecut
Ski geometry is the shape of the ski. Described in the direction of travel, the front of the ski, typically pointed or rounded, is the tip, the middle is the waist and the rear is the tail. Skis have four aspects that define their basic performance: length, width, sidecut and camber. Skis also differ in more minor ways to address certain niche roles. For instance, skis for moguls are much softer to absorb shocks from the quick and sharp turns of the moguls and skis for powder are much wider to provide more "float" in deeper, softer snow. Length and width The length and width of the ski define its total surface area, which provides some indication of the ski's float, or ability to remain on top of the snow instead of sinking into it. Cross-country skis must be narrow to reduce drag, and thus must be long to produce the required float. Alpine skis are generally not designed to reduce drag, and tend to be shorter and wider. Skis used in downhill race events are longer, with a subtl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Carve Turn
A carved turn is a skiing and snowboarding term for the technique of turning by shifting the ski or snowboard onto its edges. When edged, the sidecut geometry causes the ski (in the following, snowboard is implicit and not mentioned) to bend into an arc, and the ski naturally follows this arc shape to produce a turning motion. The carve is efficient in allowing the skier to maintain speed because, unlike the older stem Christie and parallel turns, the skis do not create drag by sliding sideways. Starting a carved turn requires the ski to be rotated onto its edge, which can be accomplished through angulation of the hips and knees applied to both skis, leading them to efficiently carve a naturally parallel turn. Carving turns are generally smoother and longer radius than either stemmed or parallel turns. Carving maintains the skis efficiently turning along the direction of travel as opposed to skidding at an angle across the direction of travel. For a given velocity, carving with ...

Off Piste
Backcountry skiing ( US), also called off-piste (Europe), alpine touring, freeriding or out-of-area, is skiing in the backcountry on unmarked or unpatrolled areas either inside or outside a ski resort's boundaries. This contrasts with alpine skiing, which is typically done on groomed trails benefiting from a ski patrol. Unlike ski touring, backcountry skiing can – and often does – include the use of ski lifts including snowcats and helicopters. Recent improvements in equipment have increased the popularity of the sport. As the sport does confront the individual practicing it with the dangers of natural, unprepared alpine terrain like avalanches, it is generally recommended to carry standard safety equipment and to learn beforehand how to behave safely under such conditions. Terminology The terms "backcountry" and "off-piste" refer to where the skiing is being done, while terms like ski touring, ski mountaineering, telemark, freeriding, and extreme skiing describe what type ...

Mogul Skiing
Mogul skiing is a freestyle skiing, freestyle skiing competition consisting of one timed run of free skiing on a steep, heavily moguled course, stressing technical turns, aerial maneuvers and speed. Internationally, the sport is contested at the FIS Freestyle World Ski Championships, and at the Freestyle skiing at the Winter Olympics, Winter Olympic Games. Moguls are a series of bumps on a piste formed when skiers push snow into mounds as they do sharp turns. This tends to happen naturally as skiers use the slope but they can also be constructed artificially. Once formed, a naturally occurring mogul tends to grow as skiers follow similar paths around it, further deepening the surrounding grooves known as troughs. Since skiing tends to be a series of linked turns, moguls form together to create a bump field. The term "mogul" is from the Bavarian language, Bavarian/Austrian German word ''Mugel'', meaning "mound, hillock". Competition The first competition involving mogul skiing ...

Line Of Greatest Slope
In topography, the line of greatest slope is a curve following the steepest slope. In mountain biking and skiing, the line of greatest slope is sometimes called the fall line.https://rootsrated.com Farlow Gap – Mountain Biking: fall line (2nd paragraph) — "The trail becomes loose and rocky, and becomes fall line into a wide open rock garden..." Definition Mathematically, the line (or path) of greatest slope from a point is determined by the of height, taken as a potential field with respect to an acceleration from the force of gravity. Lines of greatest slope are analogous to |
Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
