Factors Influencing Running Velocity at Lactate Threshold in Male and Female Runners at Different Levels of Performance
Støa, Eva Maria; Helgerud, Jan; Rønnestad, Bent; Hansen, Joar; Ellefsen, Stian; Støren, Øyvind (Peer reviewed; Journal article, 2020)Background: The primary aim was to examine the relationship between lactate threshold (LT) expressed as percentage of maximal oxygen uptake (VO2max) and running velocity at LT (LTV). A secondary aim was to investigate to ... -
The higher the fraction of maximal oxygen uptake is during interval training, the greater is the cycling performance gain
Odden, Ingvill; Nymoen, Lars; Urianstad, Tomas; Kristoffersen, Morten; Hammarström, Jens Konrad Daniel; Hansen, Joar; Mølmen, Knut Sindre; Rønnestad, Bent (Peer reviewed; Journal article, 2024)It has been suggested that time at a high fraction (%) of maximal oxygen uptake (VO2max) plays a decisive role for adaptations to interval training. Yet, no study has, to date, measured the % of VO2max during all interval ... -
A microcycle of high‐intensity short‐interval sessions induces improvements in indicators of endurance performance compared to regular training
Solli, Guro Strøm; Odden, Ingvill; Sælen, Vetle; Hansen, Joar; Mølmen, Knut Sindre; Rønnestad, Bent (Peer reviewed; Journal article, 2024)The purpose of this study was to evaluate the effects of a microcycle of high-intensity interval training (HIT) sessions with multiple short work intervals followed by an active recovery period, compared to a similar ... -
Yearly intrasubject variability of hematological biomarkers in elite athletes for the Athlete Biological Passport
Bastien, Krumm; Lundby, Carsten; Hansen, Joar; Jacob, Bejder; Henrik, Sørensen; Tristan, Equey; Jonas, Saugy; Francesco, Botrè; Raphael, Faiss (Peer reviewed; Journal article, 2024)Confounding factors including exercise and environments challenge the interpretation of individual Athlete Biological Passports (ABPs). This study aimed to investigate the natural variability of hematological ABP parameters ...
