Nordic skiing

Nordic skiing encompasses the various types of skiing in which the toe of the ski boot is fixed to the binding in a manner that allows the heel to rise off the ski,^[1] unlike alpine skiing, where the boot is attached to the ski from toe to heel. Recreational disciplines include cross-country skiing and Telemark skiing.

The biomechanics of competitive cross-country skiing and ski jumping have been the subject of serious study. Cross-country skiing requires strength and endurance and ski jumping requires aerodynamic efficiency, both of which requirements translate into specific skills[5] to be optimized in training and competition.^[6]

Origins

Recreational skiing began with organized skiing exercises and races of the Norwegian and Swedish infantries. Military races and exercises included downhill in rough terrain, target practice while skiing downhill, and 3 km cross-country skiing with full military backpack.^[7] Slalom (Norwegian: slalåm) is a word of Norwegian origin that has entered the international skiing vocabulary. In the 1800s skiers in Telemark challenged each other on "wild slopes" (ville låmir), more gentle slopes had the adjective "sla". Some races were on "bumpy courses" (kneikelåm) and sometimes included "steep jumps" (sprøytehopp) for difficulty. These 19th century races in Telemark ran along particularly difficult trails usually from a steep mountain, along timber-slides and ended with a sharp turn ("Telemark turn") on a field or icy lake.^[8]
