Sammendrag av avhandlingen:
In order to answer the overall objective, two specific aims were conducted:
1) To compare physiological capacities, and kinematical patterns in double poling between Olympic distance and long-distance XC skiers, and analyze the training characteristics of long-distance XC skiers (Studies I and II)
2) To describe choice of pole lengths among competitive XC skiers and evaluate the effects of pole length manipulation on performance in the classical and skating style of XC skiing (Studies III-VI).
The thesis contains six studies. Study I and II are comparing the physiological and kinematical responses in DP between Olympic distance and long-distance cross-country skiers while treadmill roller skiing, while study II investigated the training characteristics of world-class male long-distance cross-country skiers by using training diary data generated through questionnaires, and follow-up interviews.
Studies III-V examined the effects of increased pole length in DP, G3 skating and on-snow skating on performance, physiological and perceptual responses, as well as sub-technique selection. Study VI described the use of pole and ski length in competitive XC skiers and examined the influence of sex and performance level.
