  2. 11. Alpine skiing : injury profile, ACL risk factors and prevention

    Author : Maria Westin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Alpine skiing is a popular winter sport among children and adolescents. The combination of great physical demands and ever-changing external conditions makes competitive alpine skiing to one of our most complex sports. READ MORE

  4. 12. Properties of snow with applications related to climate change and skiing

    Author : Nina Lintzén; Sven Knutsson; Lars-Erik Persson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Snow has been a subject of research since the mid-20th century. Research on mechanical properties of snow started as an off-shoot of soil mechanics, where methods, tools and instruments used often are the same. However, during the last decades the winter business industry has been growing requiring a number of new fields of research. READ MORE

  5. 13. Physiological demands of competitive elite cross-country skiing

    Author : Magnus Carlsson; Michail Tonkonogi; Christer Malm; Eva Andersson; Högskolan Dalarna; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Performance capability; maximal oxygen uptake; lactate threshold; lean mass; double poling; power output; maximal speed; sprint skiing; distance skiing.; Hälsa och välfärd; Health and Welfare;

    Abstract : 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. READ MORE

  6. 14. Objective Analysis Methods in the Mechanics of Sports

    Author : Mikael Swarén; Anders Eriksson; Vesa Linnamo; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sports equipment; test methods; sports mechanics; biomechanics; performance analysis; tracking; positioning system; pacing; alpine skiing; cross-country skiing; poles; helmets;

    Abstract : Sports engineering can be considered as the bridge between the knowledge of sports science and the principles of engineering and has an important role not only in improving the athletic performance, but also in increasing the safety of the athletes. Testing and optimization of sports equipment and athletic performance are essential for supporting athletes in their quest to reach the podium. READ MORE

  7. 15. The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing

    Author : Mats Ainegren; Peter Carlsson; Marko Laaksonen; Per Tesch; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood lactate; cycle length; cycle rate; heart rate; oxygen uptake; performance; power; roller skis; rolling resistance; ratings of perceived exertion; work economy; Sports; Idrott;

    Abstract : 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.
