Energy system contribution during competitive cross-country skiing
Losnegard, Thomas (Peer reviewed; Journal article, 2019)Energy system contribution during cross-country (XC) skiing races is dependent on several factors, including the race dura-tion, track profile, and sub-techniques applied, and their subsequent effects on the use of the ... -
Exercise economy in skiing and running
Losnegard, Thomas; Schäfer, Daniela; Hallén, Jostein (Journal article; Peer reviewed, 2014-01-24)Substantial inter-individual variations in exercise economy exist even in highly trained endurance athletes. The variation is believed to be determined partly by intrinsic factors. Therefore, in the present study, we ... -

Næss, Steffan; Sollie, Ove; Gløersen, Øyvind Nøstdahl; Losnegard, Thomas (Peer reviewed; Journal article, 2021)Objective: To examine the power profiles and pacing patterns in relation to critical power (CP) and maximal aerobic power (MAP) output during a cross-country Olympic (XCO) mountain bike race. Methods: Five male and two ... -
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 ... -
Kinematical analysis of the V2 ski skating technique: A longitudinal study
Losnegard, Thomas; Myklebust, Håvard; Ehrhardt, Angela; Hallén, Jostein (Journal article; Peer reviewed, 2017)To characterise timing of movements and evaluate performance effects of technique alterations in V2 ski skating, 13 elite male cross-country skiers (age, 23 ± 2 years; stature, 182 ± 6 cm; body mass, 76 ± 8 kg; V2 V̇O2max, ... -
Physiological determinants of performance in modern elite cross-country skiing
Losnegard, Thomas (Doctoral thesis, 2013)This thesis consists of four studies with additional unpublished results, in which the main objective was to examine factors that determine performance in modern elite cross-country (XC) skiing. Thirty-two elite male XC ... -
Physiological differences between sprint- and distance-specialized cross-country skiers
Losnegard, Thomas; Hallén, Jostein (Journal article; Peer reviewed, 2014)Purpose: Sprint- (≤1.8 km) and distance-skiing (≥15 km) performance rely heavily on aerobic capacity. However, in sprint skiing, due to the ~20% higher speed, anaerobic capacity contributes significantly. This study aimed ... -
Pole lengths influence O2-cost during double poling in highly trained cross-country skiers
Carlsen, Camilla Høivik; Rud, Bjarne; Myklebust, Håvard; Losnegard, Thomas (Journal article; Peer reviewed, 2017)Purpose: In elite cross-country skiing, double poling is used in different terrain. This study compared O2-cost and kinematics during double poling with four different pole lengths [self-selected (SS), SS − 5 cm, SS + 5 ... -
Propulsive Power in Cross-Country Skiing: Application and Limitations of a Novel Wearable Sensor-Based Method During Roller Skiing
Gløersen, Øyvind Nøstdahl; Losnegard, Thomas; Malthe-Sørenssen, Anders; Dysthe, Dag Kristian; Gilgien, Matthias (Journal article; Peer reviewed, 2018)Cross-country skiing is an endurance sport that requires extremely high maximal aerobic power. Due to downhill sections where the athletes can recover, skiersmust also have the ability to perform repeated efforts where ... -
