Skiing

Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS).

Types

Alpine

Also called downhill skiing, alpine skiing typically takes place on a piste at a ski resort. It is characterized by fixed-heel bindings that attach at both the toe and the heel of the skier's boot. Because alpine equipment is somewhat difficult to walk in, ski lifts, including chairlifts, bring skiers up the slope. Backcountry skiing can be accessed by helicopter, snowcat, hiking and snowmobile. Facilities at resorts can include night skiing, après-ski, and glade skiing under the supervision of the ski patrol and the ski school. Alpine skiing branched off from the older Nordic skiing around the 1920s, when the advent of ski lifts meant that it was not necessary to walk any longer. Alpine equipment specialized to where it can only be used with the help of lifts.

Nordic

The Nordic disciplines include cross-country skiing and ski jumping, which share in common the use of binding that attach at the toes of the skier's boots but not at the heels. Cross-country skiing may be practiced on groomed trails or in undeveloped backcountry areas. Ski jumping skiing is practiced at certain areas that are deemed for ski jumping only.

Telemark

Telemark skiing is a ski turning technique and FIS-sanctioned discipline. It is named after the Telemark region of Norway. Using equipment similar to nordic skiing, the ski bindings having the ski boot attached only at the toe. This allows the skier to raise his/her heel throughout the turn.

Equipment used in skiing includes:
Skis, which may have skins applied or be textured for uphill traction or wax applied for minimizing sliding friction. Twin-tip skis are designed to move forwards or backwards.
Boots and bindings
Poles
Helmets and ski suits
Ski goggles
Skiing gloves

HOW TO

Technique has evolved along with ski technology and ski geometry. Early techniques included the telemark turn, the stem, the stem Christie, snowplough, and parallel turn.
New parabolic designs like the Elan SCX have enabled the more modern carve turn.
