Determinants and reference values for blood volume and total hemoglobin mass in women and men
Oberholzer, Laura; Montero, David; Robach, Paul; Siebenmann, Christoph; Ryrsøe, Camilla Koch; Bonne, Thomas C.; Breenfeldt Andersen, Andreas; Bejder, Jacob; Karlsen, Trine; Edvardsen, Elisabeth; Rønnestad, Bent; Hamarsland, Håvard; Cepeda-Lopez, Ana C.; Rittweger, Jörn; Treff, Gunnar; Ahlgrim, Christoph; Almquist, Nicki Winfield; Hallén, Jostein; Lundby, Carsten (Peer reviewed; Journal article, 2023)Blood volume (BV) is an important clinical parameter and is usually reported per kg of body mass (BM). When fat mass is elevated, this underestimates BV/BM. One aim was to study if differences in BV/BM related to sex, age, ... -
Equal-Volume Strength Training With Different Training Frequencies Induces Similar Muscle Hypertrophy and Strength Improvement in Trained Participants
Hamarsland, Håvard; Moen, Hermann; Skaar, Ole Johannes; Wahlstrøm Jorang, Preben; Sæterøy Rødahl, Håvard; Rønnestad, Bent (Peer reviewed; Journal article, 2022)The main goal of the current study was to compare the effects of volume-equated training frequency on gains in muscle mass and strength. In addition, we aimed to investigate whether the effect of training frequency was ... -
Glucose ingestion before and after resistance training sessions does not augment ribosome biogenesis in healthy moderately trained young adults
Lian, Kristian; Hammarström, Daniel; Hamarsland, Håvard; Mølmen, Knut Sindre; Moen, Sara Christine; Ellefsen, Stian (Peer reviewed; Journal article, 2024)Purpose Resistance training-induced skeletal muscle hypertrophy seems to depend on ribosome biogenesis and content. High glucose treatment may augment ribosome biogenesis through potentiating resistance training-induced ... -
The higher oxygen consumption during multiple short intervals is sex-independent and not influenced by skeletal muscle characteristics in well-trained cyclists
Urianstad, Tomas; Hamarsland, Håvard; Odden, Ingvill; Lorentzen, Håvard Crantz; Hammarström, Jens Konrad Daniel; Mølmen, Knut Sindre; Rønnestad, Bent (Peer reviewed; Journal article, 2024)It has been suggested that time spent at a high fraction of maximal oxygen consumption (%mathematical equationO2max) plays a decisive role for adaptations to interval training. However, previous studies examining how ... -
Krill oil supplementation in vivo promotes increased fuel metabolism and protein synthesis in cultured human skeletal muscle cells
Katare, Parmeshwar Bajirao; Dalmao-Fernandez, Andrea; Mengeste, Abel Mulu; Navabakbar, Farnaz; Hamarsland, Håvard; Ellefsen, Stian; Berge, Rolf Kristian; Bakke, Hege Gilbø; Nyman, Tuula Anneli; Kase, Eili Tranheim; Rustan, Arild Christian; Thoresen, G. Hege (Peer reviewed; Journal article, 2024)Introduction: Krill oil is a dietary supplement derived from Antarctic krill; a small crustacean found in the ocean. Krill oil is a rich source of omega-3 fatty acids, specifically eicosapentaenoic acid and docosahexaenoic ... -
The Kynurenine Pathway in Healthy Subjects and Subjects with Obesity, Depression and Chronic Obstructive Pulmonary Disease
Farup, Per Grønaas; Hamarsland, Håvard; Mølmen, Knut Sindre; Ellefsen, Stian; Hestad, Knut (Peer reviewed; Journal article, 2023)Background: Changes in tryptophan metabolism through the kynurenine pathway (KP) are observed in several disorders and coupled with pathophysiological deviations. Methods: This study retrospectively compared the KP in serum ... -
Vitamin D3 supplementation does not enhance the effects of resistance training in older adults
Mølmen, Knut Sindre; Hammarström, Jens Konrad Daniel; Pedersen, Karianne; Lie, Anne Cecilie Lian; Steile, Ragnvald B.; Nygård, Håvard; Khan, Yusuf; Hamarsland, Håvard; Koll, Lise; Hanestadhaugen, Marita; Eriksen, Atle Lie; Grindaker, Eirik; Whist, Jon Elling; Buck, Daniel; Ahmad, Rafi; Strand, Tor Arne; Rønnestad, Bent R.; Ellefsen, Stian (Peer reviewed; Journal article, 2021)Background: Lifestyle therapy with resistance training is a potent measure to counteract age-related loss in muscle strength and mass. Unfortunately, many individuals fail to respond in the expected manner. This phenomenon ...
