  2. 2. Roller skis' rolling resistance and grip characteristics : influences on physiological and performance measures in cross-country skiers

    Author : Mats Ainegren; Peter Carlsson; Marko Laaksonen; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adjustable grip; blood lactate; centre of pressure; cycle length; cycle rate; economy; efficiency; friction coefficient; heart rate; normal force; OBLA; oxygen uptake; power; ratcheted wheel; ratings of perceived exertion; roller skis; rolling resistance; tangential force; time to exhaustion;

    Abstract : 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. READ MORE

  3. 3. 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.

  4. 4. Physiological and biomechanical aspects of rifle carriage during biathlon skiing

    Author : Malin Jonsson Kårström; Marko Laaksonen; Kerry McGawley; Guillaume Millet; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D-measurement; anaerobic energy contribution; crosscountry skiing; kinematics; lactate threshold; load carriage; oxygen uptake; performance; sex differences; sub-techniques; training;

    Abstract : Biathlon is an endurance-based winter sport that combines crosscountry (XC) skiing with rifle marksmanship. While skiing, biathletes carry the rifle (weighing ≥ 3.5 kg) on their backs. However, research regarding the effects of rifle carriage in biathlon is lacking. READ MORE

    Author : Øyvind Karlsson; Kerry McGawley; Marko Laaksonen; Shona Halson; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; altitude training; athlete monitoring; athlete testing; biathlon; endurance exercise; epidemiology; illness; injury; metabolic profiling; metabolomics; Nordic skiing; performance development; winter sports; epidemiologi; fysiologiska tester; höghöjdträning; längdåkning; metabolisk profilering; metabolomics; monitorering; prestationsutveckling; sjukdom; skador; skidskytte; uthållighetsträning; vintersport;

    Abstract : Competitive cross-country (XC) ski athletes (defined hereafter as XC skiers and biathletes combined) are vulnerable to developing various health-related symptoms and conditions due to several factors, such as high physiological and psychological demands, extreme competition and training environments, high training loads, demanding competition schedules, and frequent travel. On initiating this work, we (the author and supervisory team) were approached by the Swedish Ski Association (SSF) and the Swedish Biathlon Federation (SSSF) to investigate the relationships between training, racing, and health problems, with a specific focus on illnesses (rather than injuries), and an ultimate goal of improving future support practices and athletic performance.
