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: ... -
Eccentric cycling does not improve cycling performance in amateur cyclists
Paulsen, Gøran; Eidsheim, Hedda; Helland, Christian; Seynnes, Olivier R.; Solberg, Paul André; Rønnestad, Bent (Peer reviewed; Journal article, 2019)Eccentric cycling training induces muscle hypertrophy and increases joint power output in non-athletes. Moreover, eccentric cycling can be considered a movement-specific type of strength training for cyclists, but it is ... -
Force-velocity profiling in athletes: Reliability and agreement across methods
Lindberg, Kolbjørn Andreas; Bjørnsen, Thomas; Helland, Christian; Rønnestad, Bent; Haugen, Thomas André; Østerås, Sindre; Kristoffersen, Morten; Paulsen, Gøran; Solberg, Paul André; Frank, Martin Thorsen; Midttun, Magnus; Sæland, Fredrik (Peer reviewed; Journal article, 2021)The aim of the study was to examine the test-retest reliability and agreement across methods for assessing individual force-velocity (FV) profiles of the lower limbs in athletes. Using a multicenter approach, 27 male ... -
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 ... -
Is Rating of Perceived Exertion a Valuable Tool for Monitoring Exercise Intensity During Steady-State Conditions in Elite Endurance Athletes?
Losnegard, Thomas Johansen; Skarli, Sondre; Hansen, Joar; Roterud, Stian; Svendsen, Ida S.; Rønnestad, Bent; Paulsen, Gøran (Peer reviewed; Journal article, 2021)Purpose: Rating of perceived exertion (RPE) is a widely used tool to assess subjective perception of effort during exercise. The authors investigated between-subject variation and effect of exercise mode and sex on Borg ... -
Strength and Power Testing of Athletes: A Multicenter Study of Test-Retest Reliability
Lindberg, Kolbjørn Andreas; Solberg, Paul André; Bjørnsen, Thomas; Helland, Christian; Rønnestad, Bent; Frank, Martin; Haugen, Tommy; Østerås, Sindre; Kristoffersen, Morten; Midttun, Magnus; Sæland, Fredrik; Eythorsdottir, Ingrid Eir Thorp; Paulsen, Gøran (Peer reviewed; Journal article, 2022)Purpose:This study examined the test–retest reliability of common assessments for measuring strength and power of the lowerbody in high-performing athletes.Methods:A total of 100 participants, including both male (n=83) ... -
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) ... -
Upper body heavy strength training does not affect performance in junior female cross-country skiers
Skattebo, Øyvind; Hallén, Jostein; Rønnestad, Bent; Losnegard, Thomas (Journal article; Peer reviewed, 2015-07-06)We investigated the effects of adding heavy strength training to a high volume of endurance training on performance and related physiological determinants in junior female cross-country skiers. Sixteen well-trained athletes ...
