Journal ArticleDOI
Superior Cardiovascular Effect of Aerobic Interval Training Versus Moderate Continuous Training in Heart Failure Patients A Randomized Study
Ulrik Wisløff,Asbjørn Støylen,Jan Pål Loennechen,Morten Bruvold,Øivind Rognmo,Per Magnus Haram,Arnt Erik Tjønna,Jan Helgerud,Stig A. Slørdahl,Sang Jun Lee,Vibeke Videm,Anja Bye,Godfrey L. Smith,Sonia M. Najjar,Øyvind Ellingsen,Terje Skjærpe +15 more
TL;DR: Exercise intensity was an important factor for reversing LV remodeling and improving aerobic capacity, endothelial function, and quality of life in patients with postinfarction heart failure.
Journal ArticleDOI
Aerobic Interval Training Versus Continuous Moderate Exercise as a Treatment for the Metabolic Syndrome: A Pilot Study
Arnt Erik Tjønna,Sang Jun Lee,Øivind Rognmo,Tomas Stølen,Anja Bye,Per Magnus Haram,Jan Pål Loennechen,Qusai Y. Al-Share,Eirik Skogvoll,Stig A. Slørdahl,Ole J. Kemi,Sonia M. Najjar,Ulrik Wisløff +12 more
TL;DR: Exercise intensity was an important factor for improving aerobic capacity and reversing the risk factors of the metabolic syndrome.
Journal ArticleDOI
The impact of high-intensity interval training versus moderate-intensity continuous training on vascular function: a systematic review and meta-analysis.
TL;DR: HIIT is more effective at improving brachial artery vascular function than MICT, perhaps due to its tendency to positively influence CRF, traditional CVD risk factors, oxidative stress, inflammation, and insulin sensitivity.
Journal ArticleDOI
Aerobic interval training reduces cardiovascular risk factors more than a multitreatment approach in overweight adolescents.
Arnt Erik Tjønna,Tomas Stølen,Anja Bye,Marte Volden,Stig A. Slørdahl,Rønnaug Ødegård,Eirik Skogvoll,Ulrik Wisløff +7 more
TL;DR: It was found that 3 months of twice weekly high-intensity exercise sessions reduced several known cardiovascular risk factors in obese adolescents more than that observed after a multitreatment strategy, which was initiated as hospital treatment.
Journal ArticleDOI
Both aerobic endurance and strength training programmes improve cardiovascular health in obese adults
Inga Ekeberg Schjerve,Gjertrud Aunet Tyldum,Arnt Erik Tjønna,Tomas Stølen,Jan Pål Loennechen,Harald E. M. Hansen,Per Magnus Haram,Garreth Heinrich,Anja Bye,Sonia M. Najjar,Godfrey L. Smith,Godfrey L. Smith,Stig A. Slørdahl,Ole J. Kemi,Ulrik Wisløff +14 more
TL;DR: An important contribution towards improved aerobic work capacity, endothelial function and cardiovascular health originates from strength training, which may serve as a substitute when whole-body aerobic exercise is contra-indicated or difficult to perform.
