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, ... -
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 ... -
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 ...
