    • Integrated framework of load monitoring by a combination of smartphone applications, wearables and point-of-care testing provides feedback that allows individual responsive adjustments to activities of daily living 

      Düking, Peter; Achtzehn, Silvia; Holmberg, Hans-Christer; Sperlich, Billy (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-19)
      Athletes schedule their training and recovery in periods, often utilizing a pre-defined strategy. To avoid underperformance and/or compromised health, the external load during training should take into account the individual’s physiological and perceptual responses. No single variable provides an adequate basis for planning, but continuous monitoring of a combination of several indicators of ...
    • Intra‐arterial blood pressure traits during and after heavy resistance exercise in healthy males 

      Heitmann, Kim Arne; Dalen, Håvard; Gundersen, Guri Holmen; Ingvaldsen, Rolf Petter; Welde, Boye (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-29)
      This randomized within‐subjects crossover‐designed study evaluated intra‐arterial blood pressure (BP) traits in seven healthy males (24 ± 1 years) during heavy resistance exercise (HRE) to failure (10 × 5 repetitions, 5RES) and not to failure (10 × 3 repetitions, 3RES), both at 5RM load. By combining few repetitions, avoidance of Valsalva maneuver, and restricting the duration of each contraction, ...
    • Kicking velocity and effect on match performance when using a smaller, lighter ball in women's football 

      Andersen, Thomas Bull; Krustrup, Peter; Bendiksen, Mads; Ørntoft, Christina; Randers, Morten B.; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-23)
      The present study evaluated the effect of a smaller, lighter ball on kicking speed and technical- tactical and physical match performance in high-level adult female footballers. In the laboratory test setting, the peak ball velocity was 6 % higher with the new ball (NB) than the standard ball (SB) (26.5 ± 0.5 vs. 25.1 ± 0.5 m · s − 1, p < 0.05). However, during match-play, no differences ...

    • Learning leadership: becoming an outdoor leader 

      Enoksen, Elisabeth; Lynch, Pip (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-19)
      Recent leadership research has demonstrated a need for better understanding the process of becoming a leader because it might be qualitatively different to being a leader. If so, there is likely to be a need for pedagogies designed deliberately to support first-time outdoor leadership experiences and any such pedagogies must be informed by the needs of first-time leaders. Becoming a leader in outdoor ...

    • Motor competence and implications in primary school 

      Mathisen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-25)
      The level of motor competence for six-year-old children are of special interest because at this age they have started at school, and they have to master new requirements. Ninety-four children were tested in fine- and gross- motor skills, by the Movement ABC test. Within the fifth percentile of the USA norms, 9.6 % of the children would have to be classified as to have motor problems, with 11.7% ...
