Branched-chain amino acid metabolism, insulin sensitivity and liver fat response to exercise training in sedentary dysglycaemic and normoglycaemic men
Lee, Sindre; Gulseth, Hanne Løvdal; Langleite, Torgrim Mikal; Norheim, Frode; Olsen, Thomas; Refsum, Helga; Jensen, Jørgen; Birkeland, Kåre I.; Drevon, Christian A (Peer reviewed; Journal article, 2020)Aims/hypothesis: Obesity and insulin resistance may be associated with elevated plasma concentration of branched-chain amino acids (BCAAs) and impaired BCAA metabolism. However, it is unknown whether the insulin-sensitising ... -
Effects of antioxidant-rich foods on altitude-induced oxidative stress and inflammation in elite endurance athletes: A randomized controlled trial
Koivisto, Anu; Olsen, Thomas; Paur, Ingvild; Paulsen, Gøran; Bastani, Nasser Ezzatkhah; Garthe, Ina; Raastad, Truls; Matthews, Jason; Blomhoff, Rune; Bøhn, Siv Kjølsrud (Peer reviewed; Journal article, 2019)Background: Various altitude training regimes, systematically used to improve oxygen carrying capacity and sports performance, have been associated with increased oxidative stress and inflammation. We investigated whether ... -
Exhaustive exercise and post-exercise protein plus carbohydrate supplementation affect plasma and urine concentrations of sulfur amino acids, the ratio of methionine to homocysteine and glutathione in elite male cyclists
Olsen, Thomas; Sollie, Ove; Nurk, Eha; Turner, Cheryl; Jernerén, Fredrik; Ivy, John L.; Vinknes, Kathrine; Clauss, Matthieu; Refsum, Helga Margaretha; Jensen, Jørgen (Peer reviewed; Journal article, 2020)Plasma and tissue sulfur amino acid (SAA) availability are crucial for intracellular methylation reactions and cellular antioxidant defense, which are important processes during exercise and in recovery. In this randomized, ... -
Extracellular vesicles and microRNAs are altered in response to exercise, insulin sensitivity and overweight
Doncheva, Atanaska Ivanova; Romero, Silvana Angelica Troncoso; Ramirez-Garrastacho, Manuel; Lee-Ødegård, Sindre; Kolnes, Kristoffer Jensen; Olsen, Thomas; Llorente, Alicia; Dalen, Knut Tomas; Hjorth, Marit; Tangen, Daniel Steensen; Drevon, Christian A. (Peer reviewed; Journal article, 2022)Abstract: Extracellular vesicles induced by exercise have emerged as potential mediators of tissue crosstalk. Extracellular vesicles and their cargo miRNAs have been linked to dysglycemia and obesity in animal models, but ...
