Contribution of oxygen extraction fraction to maximal oxygen uptake in healthy young men
Skattebo, Øyvind; Calbet, Jose Antonio Lopez; Rud, Bjarne; Capelli, Carlo; Hallén, Jostein (Peer reviewed; Journal article, 2020)We analysed the importance of systemic and peripheral arteriovenous O2 difference (a-vO2 difference and a-vfO2 difference, respectively) and O2 extraction fraction for maximal oxygen uptake (VO2max). Fick law of diffusion ... -
Exercise intensity during cross-country skiing described by oxygen demands in flat and uphill terrain
Karlsson, Øyvind; Gilgien, Matthias; Gløersen, Øyvind Nøstdahl; Rud, Bjarne; Losnegard, Thomas (Peer reviewed; Journal article, 2018)Purpose: In this study wearable global navigation satellite system units were used on athletes to investigate pacing patterns by describing exercise intensities in flat and uphill terrain during a simulated cross-country ... -
The influence of pole lengths on O2-cost, kinematics, and performance in double poling at high speeds before and after a training period with long poles
Losnegard, Thomas Johansen; Tosterud, Ola Kristoffer; Trøen, Erik; Carlsen, Camilla Høivik; Paulsen, Gøran; Rud, Bjarne (Peer reviewed; Journal article, 2019)Purpose: Previous studies have found an acute performance improvement with longer pole lengths in double poling (DP) at low-to-moderate speeds. We investigated the influence of pole lengths (PL) on O2-cost, 3D kinematics, ... -
Morning Preconditioning Exercise Does Not Increase Afternoon Performance in Competitive Runners
Dahl, Even B.; Øygard, Eivind; Paulsen, Gøran; Rud, Bjarne; Losnegard, Thomas Johansen (Peer reviewed; Journal article, 2021)Purpose: Preconditioning exercise is a widely used strategy believed to enhance performance later the same day. The authors examined the influence of preconditioning exercises 6 hours prior to a time-to-exhaustion (TTE) ... -
Peripheral adaptations to endurance training - Effect of active muscle mass
Mølmen, Knut Sindre; Hallén, Jostein; Rud, Bjarne (Peer reviewed; Journal article, 2019)The purpose of this study was to evaluate whether adaptations to endurance training are affected by active muscle mass during training. Eleven healthy subjects performed 5 weeks of one‐legged knee extension (1‐KE) training ... -
Pole Length’s Influence on Performance During Classic-Style Snow Skiing in Well-Trained Cross-Country Skiers
Trøen, Erik; Rud, Bjarne; Karlsson, Øyvind; Carlsen, Camilla Høivik; Gilgien, Matthias; Paulsen, Gøran; Tosterud, Ola Kristoffer; Losnegard, Thomas Johansen (Peer reviewed; Journal article, 2020)Purpose: To investigate how self-selected pole length (PL) of ∼84% (PL84%) compared with ∼90% (PL90%) of body height influenced performance during a 700-m time trial with undulating terrain on snow. Methods: Twenty-one ... -
What is the optimal classical style sub-technique during uphill roller skiing in elite male cross-country skiers?
Lund-Hansen, Magne; Gløersen, Øyvind; Rud, Bjarne; Losnegard, Thomas Johansen (Peer reviewed; Journal article, 2023)Purpose: To compare performance, physiological and biomechanical responses between double poling (DP) and diagonal stride (DIA) during treadmill roller skiing in elite male cross-country skiers. Method: Twelve skiers ...
