1. Double Poling Incross-Country Skiing : Biomechanical and Physiological Analysis of Sitting and Standing Positions
Sammanfattning : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. LÄS MER
2. Physiology of Cross-Country Skiing : with a special emphasis on the role of the upper body
Sammanfattning : .... LÄS MER
3. Physiological demands of competitive elite cross-country skiing
Sammanfattning : Introduction Researchers have, for decades, contributed to an increased collective understanding of the physiological demands in cross-country skiing; however, almost all of these studies have used either non-elite subjects and/or performances that emulate cross-country skiing. To establish the physiological demands of cross-country skiing, it is important to relate the investigated physiological variables to the competitive performance of elite skiers. LÄS MER
4. The importance of body-mass exponent optimization for evaluation of performance capability in cross-country skiing
Sammanfattning : Introduction Performance in cross-country skiing is influenced by the skier’s ability to continuously produce propelling forces and force magnitude in relation to the net external forces. A surrogate indicator of the “power supply” in cross-country skiing would be a physiological variable that reflects an important performance-related capability, whereas the body mass itself is an indicator of the “power demand” experienced by the skier.

5. Nonlinear response in engineered optical materials
Sammanfattning : Material and structure engineering are increasingly employed in active optical media,in this context defined as media capable of providing laser or/and optical parametric gain. For laser materials, the main aim of the engineering is to tailor the absorption and emission cross sections in order to optimise the laser performance. LÄS MER
