Extreme Carving
{{unreferenced, date=October 2013 Extreme carving or Extremecarving is a coined term describing a particular form of carving on a snowboard. Features of extreme carving that distinguish it from other kinds of snowboard carving include: *The use of wider boards to accommodate extreme edge angles (the angle between board base and snow surface) produced deep in turns. Heel and toe overhang prevent narrower boards from reaching angles close to 90 degrees that are experienced in extreme carving. *High degree of extension to the whole of the body during the middle of the carved turn, when the snowboard is facing down the fall line A fall line (or fall zone) is the area where an upland region and a coastal plain meet and is typically prominent where rivers cross it, with resulting rapids or waterfalls. The uplands are relatively hard crystalline basement rock, and the coa ... of the slope. *Proactive compression of the body during edge transitions. This maneuver is also known as a cr ...

Snowboarding
Snowboarding is a recreational and competitive activity that involves descending a snow-covered surface while standing on a snowboard that is almost always attached to a rider's feet. It features in the Winter Olympic Games and Winter Paralympic Games. Snowboarding was developed in the United States, inspired by skateboarding, sledding, surfing, and skiing. It became popular around the globe, and was introduced as a Winter Olympic Sport at Nagano in 1998 and featured in the Winter Paralympics at Sochi in 2014. , its popularity (as measured by equipment sales) in the United States peaked in 2007 and has been in a decline since. History The first snowboards were developed in 1965 when Sherman Poppen, an engineer in Muskegon, Michigan, invented a toy for his daughters by fastening two skis together and attaching a rope to one end so he would have some control as they stood on the board and glided downhill. Dubbed the "snurfer" (combining snow and surfer) by his wife Nancy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowboard
Snowboards are boards where the user places both feet, usually secured, to the same board. The board itself is wider than most skis, with the ability to glide on snow."snowboarding." Dictionary.com Unabridged (v 1.1). Random House, Inc. 17 Mar. 2009. . Snowboards widths are between 6 and 12 inches or 15 to 30 centimeters. Snowboards are differentiated from monoskis by the stance of the user. In monoskiing, the user stands with feet inline with direction of travel (facing tip of monoski/downhill) (parallel to long axis of board), whereas in snowboarding, users stand with feet transverse (more or less) to the longitude of the board. Users of such equipment may be referred to as ''snowboarder''s. ''Commercial snowboards'' generally require extra equipment such as bindings and special boots which help secure both feet of a snowboarder, who generally ride in an upright position. These types of boards are commonly used by people at ski hills, mountains, backcountry, or resorts for le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fall Line (skiing)
A fall line refers to the line down a mountain or hill which is most directly downhill; that is, the direction a ball or other body would accelerate if it were free to move on the slope under gravity. Mathematically the fall line, the line of greatest slope, is the negative of the gradient (which points uphill) and perpendicular to the contour lines. In mountain biking, a trail follows the "fall line" if it generally descends in the most downward direction, rather than traversing in a sideways direction. A skier is said to be "skiing the fall line" if they are moving generally down, making turns either side of the fall line, rather than moving across the slope. See also * Glossary of cycling * Ridge line * Topography * Topographic profile A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at eq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
