The rules for skiing were formulated in 1924 by the Fédération Internationale de Ski (FIS; International Ski Federation), world governing body for skiing. Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow. World championships sanctioned by the FIS have been held in Nordic events since 1925 for men and since 1954 for women.
Skiing and snowboarding injuries can be prevented by using proper protective gear mainly like helmets and wrist guards. Skiing and snowboarding are popular recreational and competitive sport activities for children and youth. Injuries associated with both activities are frequent and can be serious.
Origin of Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced as early as 600 BC in what is now China. The word "ski" is one of a handful of words Norway has exported to the international community. It comes from the Old Norse word "skíð" which means "split piece of wood or firewood".
