snowboard and history


Snowboards are boards, which resemble a wide ski, with the ability to glide on snow.Snowboards are differetiated from monoskis by the stance of the user. In monoskiing, the user stands with feet inline with direction of travel, whereas in snowboarding, users stand with feet transverse to the longitude of the board. Users of such equipment may be referred to as snowboarders. Commercial snowboards generally require extra equipment such as bindings and special boots which help secure both feet of a snowboarder, who generally rides in an upright position.These type of boards are commonly used by people at ski hills or resorts for leisure, entertainment and competitive purposes in the activity called snowboarding.The first object that resemble a snowboard was invented by Sherman Poppen in 1968 and was called the Snurfer.The snurfer was fairly simple and had no bindings, what is called a noboard. However the state of Utah claims that the first snowboards were developed and manufactured there in the early 1970s, and was commemorated in 2007 by the United States mint among the three semi-final designs of the Utah state quarter.At least one source believes that Jake Burton Carpenter and Tom Sims invented snowboarding.

ski and history


A ski is a long, flat device worn on the feet designed to help the wearer slide smoothly over snow. Originally intended as an aid to travel in snowy regions, they are now mainly used for recreational and sporting purposes. Also, a ski may denote a similar device used for other purposes than skiing, for example, for steering snowmobiles.The original Nordic ski technology was adapted during the early twentieth century to enable skiers to turn at higher speeds. New ski and binding designs, coupled with the introduction of ski lifts and snow cats to carry skiers up mountains, enabled the development of alpine skis. Meanwhile advances in technology in the Nordic camp allowed for the development of special skis for skating and ski jumping.
