Analysis of classical time-trial preformance and technique-specific physiological determinants in elite female cross-country skiers
Sandbakk, Øyvind; Losnegard, Thomas; Skattebo, Øyvind; Hegge, Ann M.; Tønnessen, Espen; Kocbach, Jan (Journal article; Peer reviewed, 2016-08-03)The present study investigated the contribution of performance on uphill, flat, and downhill sections to overall performance in an international 10-km classical time-trial in elite female cross-country skiers, as well as ... -
Blood volume expansion does not explain the increase in peak oxygen uptake induced by 10 weeks of endurance training
Skattebo, Øyvind; Bjerring, Anders W.; Auensen, Marius; Sarvari, Sebastian; Cumming, Kristoffer Toldnes; Capelli, Carlo; Hallén, Jostein (Peer reviewed; Journal article, 2020)Purpose: The endurance training (ET)-induced increases in peak oxygen uptake (V˙O2peak) and cardiac output (Q˙peak) during upright cycling are reversed to pre-ET levels after removing the training-induced increase in blood ... -
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 ... -
Double-Poling Physiology and Kinematics of Elite Cross-Country Skiers: Specialized Long-Distance Versus All-Round Skiers
Skattebo, Øyvind; Losnegard, Thomas Johansen; Stadheim, Hans Kristian (Peer reviewed; Journal article, 2019)Purpose: Long-distance cross-country skiers specialize to compete in races >50 km predominantly using double poling (DP). This emphasizes the need for highly developed upper-body endurance capacities and an efficient DP ... -
Effects of 150- And 450-mL Acute Blood Losses on Maximal Oxygen Uptake and Exercise Capacity
Skattebo, Øyvind; Johansen, Espen Spro; Capelli, Carlo; Hallén, Jostein (Peer reviewed; Journal article, 2021)Purpose: This study investigated whether maximal oxygen uptake (V˙O2max) and exercise capacity are affected by small acute blood loss (150 mL) and elucidated compensatory mechanisms. Methods: Thirteen male subjects (V˙O2max, ... -
Effekten av maksimal styrketrening på prestasjonen i langrenn: en 10 uker lang intervensjonsstudie
Skattebo, Øyvind (Master thesis, 2014)Formålet med denne studien var å undersøke effekten av maksimal styrketrening for overkropp på muskelstyrke, arbeidsøkonomi og prestasjonstester av ulik varighet i stakeergometer hos kvinnelige juniorlangrennsløpere. Seksten ... -
Impact of baseline serum ferritin and supplemental iron on altitude-induced hemoglobin mass response in elite athletes
Koivisto-Mørk, Anu; Svendsen, Ida Siobhan; Skattebo, Øyvind; Hallén, Jostein; Paulsen, Gøran (Peer reviewed; Journal article, 2021)The present study explored the impact of pre-altitude serum (s)-ferritin and iron supplementation on changes in hemoglobin mass (ΔHbmass) following altitude training. Measures of Hbmass and s-ferritin from 107 altitude ... -
The importance of oxygen extraction and blood volume for maximal oxygen uptake
Skattebo, Øyvind (Doctoral thesis, 2020)This thesis includes four research papers, based on four separate studies aiming to elucidate the importance of O2 extraction and blood volume (BV) for maximal O2 uptake (VO2max). In study I, twelve untrained subjects ... -
Increased Mass-Specific Maximal Fat Oxidation Rate with Small versus Large Muscle Mass Exercise
Skattebo, Øyvind; Peci, Dafina; Clauss, Matthieu; Johansen, Egil Ivar; Jensen, Jørgen (Peer reviewed; Journal article, 2022)Introduction: Skeletal muscle perfusion and oxygen (O2) delivery are restricted during whole-body exercise due to a limited cardiac output (Q[Combining Dot Above]). This study investigated the role of reducing central ... -
Individual variations in pre-altitude hemoglobin mass influence hemoglobin mass responses to repeated altitude sojourns
Skattebo, Øyvind; Hallén, Jostein (Peer reviewed; Journal article, 2022)Introduction: Previous studies have shown variable within-subject hemoglobin mass (Hbmass) responses to altitude training. We investigated whether Hbmass responses depend on individual variations in pre-altitude Hbmass ... -
The influence of pole length on performance, O2-cost and kinematics in double poling
Losnegard, Thomas; Myklebust, Håvard; Skattebo, Øyvind; Stadheim, Hans Kristian; Sandbakk, Øyvind; Hallén, Jostein (Journal article; Peer reviewed, 2016-04-27)Purpose: In the double poling cross-country skiing technique, the propulsive forces are transferred solely through the poles. The aim of the present study was to investigate how pole length influences double poling ... -
The physiological capacity of the world's highest ranked female cross-country skiers
Sandbakk, Øyvind; Hegge, Ann Magdalen; Losnegard, Thomas; Skattebo, Øyvind; Tønnessen, Espen; Holmberg, Hans-Christer (Journal article; Peer reviewed, 2016-06)Purpose: The objective of this study is to compare the physiological capacity and training characteristics of the world_s six highest ranked female cross-country skiers (world class (WC)) with those of six competitors of ... -
