2. 1. 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

4. 2. The importance of body-mass exponent optimization for evaluation of performance capability in cross-country skiing

   Author : Tomas Carlsson; Michail Tonkonogi; Christer Malm; Klavs Madsen; Högskolan Dalarna; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allometric scaling; power-function modelling; maximal oxygen uptake; body mass; elite skiers; distance skiing; lactate threshold; double poling; sprint skiing; competition; power output; time trial; Hälsa och välfärd; Health and Welfare;

   Abstract : 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. 3. PHYSIOLOGICAL AND BIOMECHANICAL FACTORS DETERMINING CROSS-COUNTRY SKIING PERFORMANCE

   Author : Erik Andersson; Hans-Christer Holmberg; Glenn Björklund; Thomas Stöggl; Jos J. de Koning; Mittuniversitetet; []
   Keywords : cycle characteristics; energy cost; energy yield; incline; joint angles; kinematics; kinetics; mechanics; Nordic skiing; oxygen deficit; oxygen demand; technique transitions; total metabolic rate.;

   Abstract : Cross-country (c.c.) skiing is a complex sport discipline from both physiological and biomechanical perspectives, with varying course topographies that require different proportions of the involved sub-techniques to be utilised. A relatively new event in c. READ MORE

6. 4. 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

   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.
