1. Roller skis' rolling resistance and grip characteristics : influences on physiological and performance measures in cross-country skiers
Sammanfattning : The aim of this thesis was to investigate roller ski characteristics; classical and freestyle roller skis’ rolling resistance coefficients (μR) and classical style roller skis’ static friction coefficients (μS), and to study the influence of different μR and μS on cross-country skiers’ performance and both physiological and biomechanical indices. The aim was also to study differences in skiing economy and efficiency between recreational skiers, female and male junior and senior elite cross-country skiers. LÄS MER
2. The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing
Sammanfattning : Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical performance in a laboratory environment using classical and freestyle techniques on roller skis. For elite athletes the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance coefficient, µR, in order to allow correct comparisons between the results, as well as providing the opportunity to study work economy between different athletes, test occasions and core techniques.

3. Bioenergetic and Mechanical Modeling of Endurance Sports with Emphasis on Individualization
Sammanfattning : Endurance athletes strive to improve their race times by enhancing their physical abilities, techniques, tactics, and equipment. Numerical simulations can aid in this effort by enabling repeated testing under identical conditions, thus isolating the effect of a single variable of interest on race time. LÄS MER
