We conclude from the results of this study that, in contrast to gait transitions in fourlegged animals, cross-country skiers revert to a gait pattern at high speeds of skiing that is rejected at a slow speed of skiing. We found that this is primarily associated with the increasingly inefficient action of the arms and poles at increased speeds and the primary reliance on arm and pole propulsion when using the one-skate technique. Furthermore, we conclude that breathing coupled with the arm action in two-skate skiing infers a distinct metabolic advantage compared to decoupled breathing. Finally, the metabolic cost of double poling decreases linearly with increasing pole lengths for poles in the range of 73-98% of a skier`s body height.
