    • Anaerobic Capacity in Running: The Effect of Computational Method 

      Andersson, Erik; Björklund, Glenn; McGawley, Kerry (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-04)
      <i>Introduction</i>: To date, no study has compared anaerobic capacity (AnC) estimates computed with the maximal accumulated oxygen deficit (MAOD) method and the gross energy cost (GEC) method applied to treadmill running exercise.<br><br> <i>Purpose</i>: Four different models for estimating anaerobic energy supply during treadmill running exercise were compared.<br><br> <i>Methods</i>: Fifteen ...

    • A heat and moisture-exchanging mask impairs self-paced maximal running performance in a sub-zero environment 

      Hanstock, Helen; Stenfors, Nikolai; Andersson, Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-29)
      Purpose - Heat-and-moisture-exchanging devices (HME) are commonly used by endurance athletes during training in sub-zero environments, but their effects on performance are unknown. We investigated the influence of HME usage on running performance at − 15 °C.<p> <p>Methods - Twenty-three healthy adults (15 male, 8 female; age 18–53 years; V˙O<sub>2peak</sub> men 56 ± 7, women 50 ± 4 mL·kg<sup>−1 ...

    • Influence of large-scale asperities on the stability of concrete dams 

      Ulfberg, Adrian; Jaime, Gonzales-Libreros; Das, Oisik; Sas, Gabriel; Andersson, Erik; Bista, Dipen; Arntsen, Bård; Seger, Andreas (Chapter; Bokkapittel, 2022)
      For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour of interfaces under shear. This study investigates the behaviour of concrete dam scale models with varying interface geometries, under a realistic set of eccentric loads. The outcome ...

    • Pacing, Exercise Intensity, and Technique by Performance Level in Long-Distance Cross-Country Skiing 

      Stöggl, Thomas; Hertlein, Markus; Brunauer, Richard; Welde, Boye; Andersson, Erik; Swarén, Mikael (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-14)
      <p>Introduction</i>: Long-distance cross-country skiing (XCS) has gained increased popularity within the past decades. However, research about long-distance XCS is limited; therefore, the aim of this study was to analyze the intensity distribution, technique application, and pacing strategies during long-distance XCS racing.<p> <p><i>Methods</i>: Heart rate (HR) and section skiing speeds of 9 ...

    • Physiological responses and cycle characteristics during double-poling versus diagonal-stride roller-skiing in junior cross-country skiers 

      Andersson, Erik; Hämberg, Irina; Do Nascimento Salvador, Paulo Cesar; McGawley, Kerry (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-24)
      <p>Purpose: This study aimed to compare physiological factors and cycle characteristics during cross-country (XC) roller-skiing at matched inclines and speeds using the double-poling (DP) and diagonal-stride (DS) sub-techniques in junior female and male XC skiers. <p>Methods: Twenty-three well-trained junior XC skiers (11 women, 12 men; age 18.2 ± 1.2 yr.) completed two treadmill roller-skiing tests ...

    • Validity and Reliability of Hydraulic-Analogy Bioenergetic Models in Sprint Roller Skiing 

      Lidar, Julius; Andersson, Erik; Sundström, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-13)
      Purpose: To develop a method for individual parameter estimation of four hydraulic-analogy bioenergetic models and to assess the validity and reliability of these models’ prediction of aerobic and anaerobic metabolic utilization during sprint roller-skiing.<p> <p>Methods: Eleven elite cross-country skiers performed two treadmill roller-skiing time trials on a course consisting of three flat ...
