  • Lorås, Håvard; Haga, Monika; Sigmundsson, Hermundur (MDPI AG, 2020-01-29)
    Acute exercise influences human cognition, and evidence suggests that learning can be improved. According to the cognitive-energetic approach towards exercise cognition, exercise represents a stressor that elevates physiological arousal, which, in turn, ...
  • Stranda, Håvard; Haga, Monika; Sigmundsson, Hermundur; Lorås, Håvard (MDPI AG, 2019-02-26)
    Acute exercise has an influence on human cognition, and both theoretical approaches and previous investigations suggest that the learning process can be facilitated. A distinction has been made however, between the predominately positive effects on ...
