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 ... -
Determinants and reference values for blood volume and total hemoglobin mass in women and men
(Peer reviewed; Journal article, 2024-01-01)Blood volume (BV) is an important clinical parameter and is usually reported per kg of body mass (BM). When fat mass is elevated, this underestimates BV/BM. One aim was to study if differences in BV/BM related to sex, age, ... -
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, ... -
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 ...
