Abstract

The term high-performance skiing commonly refers to ski racing, speed skiing, acrobatic skiing, ski jumping, and extreme skiing, usually in association with organized, high-level competition. In this chapter we will look at a few issues related to high-performance, competitive skiing that should, nevertheless, prove interesting to recreational skiers. For example, any factor that decreases velocity, as aerodynamic drag does, is crucially important for the high-performance racer or speed skier. Although aerodynamic drag is usually not an especially important issue for recreational skiers, it affects the recreational skier in the same manner that it affects a racer or speed skier. For that reason, all skiers may achieve some greater understanding of their performance—whether it be high, medium, or low—by understanding something about the way aerodynamic drag affects a skier, which is the first high-performance skiing issue we will consider.
