2. 1. On the Multi-Scale Nature of Ski-Snow Friction : Field Testing, Characterisation and Modelling of Cross-Country Ski Performance

   Author : Kalle Kalliorinne; Andreas Almqvist; Roland Larsson; Steph Forrester; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cross-Country Skiing; Winter Sports; Winter Olympics; Multi-Scale; Sports Equipment; Contact Mechanics; Ski-Camber Profile; Ski-Base Texture; Ski; Snow; Friction; RTK-GNSS; Machine Elements; Maskinelement;

   Abstract : The goal of most endurance sports is to get from point A to B in the shortest time possible. Throughout the course, athletes need to overcome the resistive forces that are present in their specific sport. READ MORE

4. 2. Alpine ski sport injuries in Swedish Lapland

   Author : Curt Made; Lars-Gunnar Elmqvist; Herbert Sandström; Robert J Johnson; Umeå universitet; []
   Keywords : skiing; wounds and injuries; Orthopaedics; ortopedi;

   Abstract : Downhill skiing is associated with recreation, youth, speed, aerials and crowded courses which carry increased risk of injuries. The aim of this study was to evaluate downhill sport injuries in a Swedish ski resort. Material and methodsIn a case-control study ongoing 1989/90–2006/07, 3,696 injured skiers were registered.

   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.

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

7. 5. 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
