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 lower body negative pressure on phase I cardiovascular responses at exercise onset
(Peer reviewed; Journal article, 2020)We hypothesised that vagal withdrawal and increased venous return interact in determining the rapid cardiac output (CO) response (phase I) at exercise onset. We used lower body negative pressure (LBNP) to increase blood ... -
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, ...
