1. 1. Objective Analysis Methods in the Mechanics of Sports

   Författare :Mikael Swarén; Anders Eriksson; Vesa Linnamo; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Experimental test setups and simulations in skiing mechanics

   Författare :Mikael Swarén; Anders Eriksson; Thomas Stöggl; KTH; []
   Nyckelord :sports equipment; test methods; sports mechanics; alpine skiing; cross-country skiing; poles; helmets; glide; performance;

   Sammanfattning : Product testing and development are essential parts in sports and for the athletes in their quest to reach the podium. Manufacturers of sports equipment often use basic test methods which do not test the equipment in a sports specific way. LÄS MER

4. 3. Numerical optimization of pacing strategies in locomotive endurance sports

   Författare :David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. Idrottsprofilerad utbildning : i spåren av en avreglerad skola

   Författare :Magnus Ferry; Håkan Larsson; Jane Meckbach; Eivind Åsrum Skille; Gymnastik- och idrottshögskolan; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bourdieu; field of education; field of sport; neoliberal discourse; pupils; school sports; teachers; Samhällsvetenskap Humaniora; Social Sciences Humanities; Bourdieu; field of education; field of sport; neoliberal discourse; pupils; school sports; teachers;

   Sammanfattning : This thesis aims to contribute to a deeper understanding of the Swedish school sports system, a system which has evolved since the beginning of the 1970s, the prevalence of which has increased significantly at all school levels since the mid-1990s and today attracts a large number of pupils and teachers.Starting with the neoliberal discourse which has had a major impact on the development of the Swedish school system, and inspired by Pierre Bourdieu’s theoretical framework, the reasons for the emergence of the school sports system and the reasons why schools chose to specialise in sport is described.

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

   Författare :Kalle Kalliorinne; Andreas Almqvist; Roland Larsson; Steph Forrester; Luleå tekniska universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
