Sample text

In these tests a 20-s incremental double poling exercise was used, corresponding to the 20–25 s time to skiskate the 200 m indoor track at maximal velocity. The upper body power of female skiers was only ~ 65% of that of male skiers, indicating that the upper body power of female skiers is much lower than could be expected from their upper body VO2max, 76–81% of the male skiers. Upper body power has significantly correlated with race performance and with roller skiing VO2max. Main points to remember about neuromuscular and muscle power characteristcs • Skiers most probably have enough maximal muscle strength but they may have limitations in fast force production and in the ability to keep up force production throughout the whole duration of a ski-race.

Young skiers cannot sustain as high a percentage of VO2max during prolonged exercise or ski-racing as world-class skiers, even though their threshold values are the same. • World-class skiers use a slightly higher percentage of their VO2max during prolonged exercise and during fast skiing than less successful skiers. • Blood lactate concentration at the intensity of maximal lactate steady state can range individually from 2 to 8 mmol·l–1. Skiing economy and comparison of different skiing techniques Mechanical efficiency is defined as the relation between mechanical work carried out and energy expended.
