Blood volume expansion does not explain the increase in peak oxygen uptake induced by 10 weeks of endurance training
(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
(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 ... -
Effect of high-intensity interval training on cardiorespiratory fitness, physical activity and body composition in people with schizophrenia: a randomized controlled trial
(Peer reviewed; Journal article, 2020)Background Exercise may improve cardiorespiratory fitness in people with schizophrenia, however, possible condition-specific cardiorespiratory disadvantages, a scarcity of methodologically sound studies, and conflicting ... -
Effects of 150- And 450-mL Acute Blood Losses on Maximal Oxygen Uptake and Exercise Capacity
(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 data averaging strategies on V̇O2max assessment: Mathematical modeling and reliability
(Peer reviewed; Journal article, 2019)Background: No consensus exists on how to average data to optimize VO2max assessment. Although the VO2max value is reduced with larger averaging blocks, no mathematical procedure is available to account for the effect of ... -
Increased Mass-Specific Maximal Fat Oxidation Rate with Small versus Large Muscle Mass Exercise
(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
(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 ... -
Is Rating of Perceived Exertion a Valuable Tool for Monitoring Exercise Intensity During Steady-State Conditions in Elite Endurance Athletes?
(Peer reviewed; Journal article, 2021)Purpose: Rating of perceived exertion (RPE) is a widely used tool to assess subjective perception of effort during exercise. The authors investigated between-subject variation and effect of exercise mode and sex on Borg ... -
Is there an association between total physical activity level and VO2max among fitness club members?: A cross-sectional study
(Peer reviewed; Journal article, 2022)Background: Since cardiorespiratory fitness is an important predictor for all-cause mortality, it is of interest to know if meeting the physical activity (PA) recommendations is associated with higher levels of maximal ... -
The road to the Beijing Winter Olympics and beyond: Opinions and perspectives on physiology and innovation in winter sport
(Peer reviewed; Journal article, 2021)Beijing will host the 2022 Winter Olympics, and China strengthens research on various aspects to allow their athletes to compete successfully in winter sport. Simultaneously, Government-directed initiatives aim to increase ... -
Sex differences in physiological determinants of performance in elite adolescent, junior, and senior cross-country skiers
(Peer reviewed; Journal article, 2022)Purpose: To compare sex differences in physiological determinants of skiing performance in elite adolescent, junior, and senior cross-country skiers matched for within-age-group performance level. Methods: Eight male ... -
What is the optimal classical style sub-technique during uphill roller skiing in elite male cross-country skiers?
(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 ...
