    • Accelerations and high intensity running in field and assistant football referees during match play 

      Riiser, Amund; Pettersen, Svein Arne; Andersen, Vidar; Sæterbakken, Atle Hole; Frøyd, Christian; Ylvisåker, Einar; Moe, Vegard Fusche (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-20)
      <p><i>Objectives</i>: (1) to examine accelerations and high intensity running (HIR) in football field referees (FR) and assistant referees (AR) during football matches and (2) to evaluate fluctuations in accelerations and HIR between first and second half and in 5-min periods.</p> <p><i>Methods</i>: All movements of the referees were measured using a radio-based tracking system during 41 matches ...

    • Aerobic Games and Playful Exercises in 9-Year-Old Boys: Intensity and Fitness Effects 

      Mathisen, Gunnar; Jensen, Rein Magnus; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      Previous research on exercise for pre-adolescents with the purpose of improving aerobic fitness levels has yielded contradictory results. Sufficient training intensity, frequency and duration are the crucial factors in achieving this goal; the question, however, is whether it is possible to reach sufficient intensity levels using aerobic games and playful exercises. Variety and fun are the important ...

    • Anthropometric factors related to sprint and agility performance in young male soccer players 

      Mathisen, Gunnar; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-05)
      Objective: To investigate the relationship between anthropometrics and sprint and agility performance and describe the development of sprint (acceleration) and agility performance in 10- to 16-year-old male soccer players. <p>Methods: One hundred and thirty-two participants were divided into three age groups, 10–12 years (mean 10.8±0.50), 13–14 years (mean 13.9±0.50), and 15–16 years (mean 15.5±0.24), ...

    • Improved maximal strength is not associated with improvements in sprint time or jump height in high-level female football players: a clusterrendomized controlled trial 

      Pedersen, Sigurd; Heitmann, Kim Arne; Sagelv, Edvard Hamnvik; Johansen, Dag; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-17)
      <i>Background</i> - Maximal strength increments are reported to result in improvements in sprint speed and jump height in elite male football players. Although similar effects are expected in females, this is yet to be elucidated. The aim of this study was to examine the effect of maximal strength training on sprint speed and jump height in high-level female football players.<p> <p><i>Methods</i> ...

    • 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 ...

    • Physiological Comparisons of Elite Male Visma Ski Classics and National Level Cross-Country Skiers During Uphill Treadmill Roller Skiing 

      Sagelv, Edvard Hamnvik; Engseth, Tina; Pedersen, Sigurd; Pettersen, Svein Arne; Mathisen, Gunnar; Heitmann, Kim Arne; Welde, Boye; Thomassen, Tor Oskar; Stoggl, Thomas Leonhard (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-16)
      Longer distance cross-country ski (14–220 km) races such as the Visma Ski Classics (VSC) has recently gained attention in addition to the traditional Olympic distances (5–50 km) associated with cross-country (XC) skiing. These long-distance races are characterized by extensive use of the upper body while double poling (DP). While there is a substantial amount of research on Olympic distance XC skiing, ...

    • Position specific player load during match-play in a professional football club 

      Baptista, Ivan; Johansen, Dag; Seabra, André; Pettersen, Svein Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)
      There is a rapid growing body of knowledge regarding physical aspects of a football match due to studies using computer-assisted motion analysis. The present study used time-motion analysis and triaxial-accelerometers to obtain new insights about differences in physical profiles of elite football players across playing-positions. Player performance data in 23 official home matches from a professional ...

    • Quantified Soccer Using Positional Data: A Case Study 

      Pettersen, Svein Arne; Johansen, Håvard D.; Baptista, Ivan; Halvorsen, Pål; Johansen, Dag (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-06)
      Performance development in international soccer is undergoing a silent revolution fueled by the rapidly increasing availability of athlete quantification data and advanced analytics. Objective performance data from teams and individual players are increasingly being collected automatically during practices and more recently also in matches after FIFA's 2015 approval of wearables in electronic ...
