   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.

4. 17. New methods for movement technique development in cross-country skiing using mathematical models and simulation

   Author : Marie Lund Ohlsson; Mårten Gulliksson; Lars-Erik Persson; Fredrik Ståhl; Peter Carlsson; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied mathematics; Tillämpad matematik;

   Abstract : This Licentiate Thesis is devoted to the presentation and discussion of some new contributions in applied mathematics directed towards scientific computing in sports engineering. It considers inverse problems of biomechanical simulations with rigid body musculoskeletal systems especially in cross-country skiing. READ MORE

5. 18. Metabolic and Cardiovascular Responses During Variable Intensity Exercise

   Author : Glenn Björklund; Mittuniversitetet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cross-country skiing; cycling; heart rate; lactate; O2 extraction; O2 uptake; performance; ventilation; Sports; Idrott;

   Abstract : Previous research investigating endurance sports from a physiological perspectivehas mainly used constant or graded exercise protocols, although the nature ofsports like cross-country skiing and road cycling leads to continuous variations inworkload. Current knowledge is thus limited as regards physiological responses tovariations in exercise intensity. READ MORE

6. 19. Numerical optimization of pacing strategies in locomotive endurance sports

   Author : David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pacing strategy; optimization; numerical simulation; equations of motion; method of moving asymptotes; cross-country skiing; cycling; Farthållningsstrategi; optimering; numerisk simulering; rörelseekvationer; method of moving asymptotes; längdskidåkning; cykling;

   Abstract : This thesis is devoted to the optimization of pacing strategies in two locomotive endurance sports; cross-country skiing and road cycling. It has been established that constant pace and variable power distributions are optimal if purely mechanical aspects of locomotion are considered in these sports. READ MORE

7. 20. The elite cross-country skier : clinical and sports related functional tests, dance training, injuries and self-related health

   Author : Marie Alricsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The general aim of this thesis was to study cross-country skiers regarding the effect of dance training on joint mobility and muscle flexibility of the spine, hip and ankle and on speed and agility. Another aim was to perform test-retests of joint mobility and muscle flexibility of the hip and of sports related functional tests. READ MORE
