The Effect of Carbohydrate Intake on Strength and Resistance Training Performance: A Systematic Review
Henselmans, Menno; Bjørnsen, Thomas; Hedderman, Richie; Vårvik, Fredrik Tonstad (Peer reviewed; Journal article, 2022)High carbohydrate intakes are commonly recommended for athletes of various sports, including strength trainees, to optimize performance. However, the effect of carbohydrate intake on strength training performance has not ... -
Effect of free-weight vs. machine-based strength training on maximal strength, hypertrophy and jump performance – a systematic review and meta-analysis
Haugen, Markus Estifanos; Vårvik, Fredrik Tonstad; Larsen, Stian; Haugen, Arvid Steinar; van den Tillaar, Roland Johannes Wilhelmus; Bjørnsen, Thomas (Peer reviewed; Journal article, 2023)Background The efectiveness of strength training with free-weight vs. machine equipment is heavily debated. Thus, the purpose of this meta-analysis was to summarize the data on the efect of free-weight versus machine-based ... -
Effect of isolated and combined ingestion of caffeine and citrulline malate on resistance exercise and jumping performance: a randomized double-blind placebo-controlled crossover study
Haugen, Markus Estifanos; Vårvik, Fredrik Tonstad; Grgic, Jozo; Studsrud, Henrik; Austheim, Espen; Zimmermann, Erik Mathias; Falch, Hallvard Nygaard; Larsen, Stian; van den Tillaar, Roland Johannes Wilhelmus; Bjørnsen, Thomas (Peer reviewed; Journal article, 2023)Purpose The aim of this study was to explore the isolated and combined efects of cafeine and citrulline malate (CitMal) on jumping performance, muscular strength, muscular endurance, and pain perception in resistance-trained ... -

The effects of being told you are in the intervention group on training results: a pilot study
Lindberg, Kolbjørn Andreas; Bjørnsen, Thomas; Vårvik, Fredrik Tonstad; Paulsen, Gøran; Joensen, Malene; Kristoffersen, Morten; Sveen, Ole; Gundersen, Hilde; Slettaløkken, Gunnar; Brankovic, Robert; Solberg, Paul Andre (Peer reviewed; Journal article, 2023)Little is known about the placebo effects when comparing training interventions. Consequently, we investigated whether subjects being told they are in the intervention group get better training results compared to subjects ... -
