      Sperlich, Billy; Wallmann-Sperlich, Birgit; Zinner, Christoph; Von Stauffenberg, Valerie; Losert, Heidrun; Holmberg, Hans-Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-03)
      The effects of circuit-like functional high-intensity training (Circuit<sub>HIIT</sub>) alone or in combination with high-volume low-intensity exercise (Circuit<sub>combined</sub>) on selected cardio-respiratory and metabolic parameters, body composition, functional strength and the quality of life of overweight women were compared. In this single-center, two-armed randomized, controlled study, ...
    • The physiological mechanisms of performance enhancement with sprint interval training differ between the upper and lower extremities in humans 

      Zinner, Christoph; Morales-Alamo, David; Ørtenblad, Niels; Larsen, Filip J; Schiffer, Tomas A; Willis, Sarah J; Gelabert-Rebato, Miriam; Perez-Valera, Mario; Boushel, Robert; Calbet, Jose AL; Holmberg, Hans-Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-30)
      To elucidate the mechanisms underlying the differences in adaptation of arm and leg muscles to sprint training, over a period of 11 days 16 untrained men performed six sessions of 4–6 × 30-s all-out sprints (SIT) with the legs and arms, separately, with a 1-h interval of recovery. Limb-specific VO2peak, sprint performance (two 30-s Wingate tests with 4-min recovery), muscle efficiency and ...
    • Prolonged sitting interrupted by 6-min of high-intensity exercise: Circulatory, metabolic, hormonal, thermal, cognitive, and perceptual responses 

      Sperlich, Billy; De Clerck, Ine; Zinner, Christoph; Holmberg, Hans-Christer; Wallmann-Sperlich, Birgit (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-16)
      The aim was to examine certain aspects of circulatory, metabolic, hormonal, thermoregulatory, cognitive, and perceptual responses while sitting following a brief session of high-intensity interval exercise. Twelve students (five men; age, 22 ± 2 years) performed two trials involving either simply sitting for 180 min (SIT) or sitting for this same period with a 6-min session of high-intensity ...
