Acute and long-term effects of blood flow restricted training on heat shock proteins and endogenous antioxidant systems
Cumming, Kristoffer Toldnes; Ellefsen, Stian; Rønnestad, Bent; Ugelstad, Ingrid; Raastad, Truls (Journal article; Peer reviewed, 2016)Blood flow restricted exercise (BFRE) with low loads has been demonstrated to induce considerable stress to exercising muscles. Muscle cells have developed a series of defensive systems against exercise-induced stress. ... -
Adaptations to strength training differ between endurance-trained and untrained women
Vikmoen, Olav; Raastad, Truls; Ellefsen, Stian; Rønnestad, Bent (Peer reviewed; Journal article, 2020)Purpose: The purpose of this study was to investigate if endurance athletes, sustaining their normal endurance training, experience attenuated adaptations to strength training compared to untrained individuals. Methods: ... -
Chronic obstructive pulmonary disease does not impair responses to resistance training
Mølmen, Knut Sindre; Hammarström, Jens Konrad Daniel; Falch, Gunnar Slettaløkken; Grundtvig, Morten; Koll, Lise; Hanestadhaugen, Marita; Khan, Yusuf; Ahmad, Rafi; Malerbakken, Bente; Lien, Roger; Raastad, Truls; Ellefsen, Stian; Rødølen, Tore Jørgen; Rønnestad, Bent R. (Peer reviewed; Journal article, 2021)Background: Subjects with chronic obstructive pulmonary disease (COPD) are prone to accelerated decay of muscle strength and mass with advancing age. This is believed to be driven by disease-inherent systemic pathophysiologies, ... -
Effects of a 10-d Military Field Exercise on Body Composition, Physical Performance, and Muscle Cells in Men and Women
Vikmoen, Olav; Teien, Hilde Kristin; Tansø, Rita; Aandstad, Anders; Lander, Elise; Cumming, Kristoffer Toldnes; Ellefsen, Stian; Helkala, Kirsi Marjaana; Raastad, Truls (Peer reviewed; Journal article, 2023)Purpose: To investigate the effects of a demanding military field exercise on physical performance, body composition and muscle cellular outcomes in men and women. Methods: Ten men (20.5 ± 0.5 years) and 8 women (21.4 ± ... -
Effects of heavy strength training on running performance and determinants of running performance in female endurance athletes
Vikmoen, Olav; Raastad, Truls; Seynnes, Olivier R.; Bergstrøm, Kristoffer; Ellefsen, Stian; Rønnestad, Bent R. (Journal article; Peer reviewed, 2016-03-08)Purpose: The purpose of the current study was to investigate the effects of adding strength training to normal endurance training on running performance and running economy in well-trained female athletes. We hypothesized ... -
Heavy strength training improves running and cycling performance following prolonged submaximal work in well‐trained female athletes
Vikmoen, Olav; Rønnestad, Bent R.; Ellefsen, Stian; Raastad, Truls (Journal article; Peer reviewed, 2017-03)The purpose of this study was to investigate the effects of adding heavy strength training to female duathletes' normal endurance training on both cycling and running performance. Nineteen well‐trained female duathletes ... -
Irisin and FNDC5: effects of 12-week strength training, and relations to muscle phenotype and body mass composition in untrained women
Ellefsen, Stian; Vikmoen, Olav; Slettaløkken, Gunnar; Whist, Jon Elling; Nygård, Håvard; Hollan, Ivana; Rauk, Irene; Vegge, Geir; Strand, Tor A.; Raastad, Truls; Rønnestad, Bent (Journal article; Peer reviewed, 2014-06-07)Purpose: To investigate the effects of strength training on abundances of irisin-related biomarkers in skeletal muscle and blood of untrained young women, and their associations with body mass composition, muscle phenotype ... -
Superiority of High-Load vs. Low-Load Resistance Training in Military Cadets
Øfsteng, Sjur Johansen; Hammarström, Daniel; Knox, Silje; Jøsok, Øyvind; Helkala, Kirsi Marjaana; Koll, Lise; Hanestadhaugen, Marita; Raastad, Truls; Rønnestad, Bent; Ellefsen, Stian (Peer reviewed; Journal article, 2024)Muscle strength and power are important determinants of soldiers' performance in modern warfare. Here, we compare the efficacy of 22 weeks of whole-body resistance training with high load (HL, 10 repetitions maximum/RM) ...
