  1. 1. Competing Under Pressure : State Anxiety, Sports Performance and Assessment

    Författare :Carolina Lundqvist; Peter Hassmén; Andrew Lane; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; competition; intra-individual variability; directional interpretations; emotions; sports performance; CSAI-2; psychometrics; Psychology; Psykologi; Samhällsvetenskap Humaniora;

    Sammanfattning : Elevated levels of anxiety are a common response to stressful competitive sports situations, are known to moderate athletic performance and are referred to as an unpleasant emotional state associated with perceptions of situational threat. The empirical studies in this dissertation considered primarily psychometric, methodological and conceptual issues of relevance for the study of anxiety and sports performance. LÄS MER

  3. 2. System analysis of kitesurfing : Understanding performance and injury risk for on-water board sports

    Författare :Lina Lundgren; Sofia Brorsson; Anna-Lisa Osvalder; Högskolan i Halmstad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sport performance; sport injury; musculoskeletal stress; system analysis; usability problems; human movement; Sports; Idrott; MEDICINE; MEDICIN;

    Sammanfattning : Board sports are examples of sports where the interaction of the task, environment and the athlete are essential. As for other sports, there are injuries and other issues associated with these sports, which affect performance and that can be avoided by proper preparation and well- designed equipment. LÄS MER

  4. 3. The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing

    Författare :Mats Ainegren; Peter Carlsson; Marko Laaksonen; Per Tesch; Mittuniversitetet; []
    Nyckelord :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;

    Sammanfattning : 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.

  5. 4. 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

  7. 5. Performance Monitoring and Control in Wireless Sensor Networks

    Författare :Ibrahim Orhan; Thomas Lindh; Ilangko Balasingham; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; body sensor networks; wireless sensor networks; performance monitoring; performance control; admission control; Bluetooth performance; clock drift compensation; time synchronization;

    Sammanfattning : Wireless personal area networks have emerged as an important communication infrastructure in areas such as at-home healthcare and home automation, independent living and assistive technology, as well as sports and wellness. Wireless personal area networks, including body sensor networks, are becoming more mature and are considered to be a realistic alternative as communication infrastructure for demanding services.
