Hemoglobin Mass, Blood Volume and VO₂max of Trained and Untrained Children and Adolescents Living at Different Altitudes.

ABSTRACT: Introduction: To a considerable extent, the magnitude of blood volume (BV) and hemoglobin mass (Hbmass) contribute to the maximum O₂-uptake (VO₂max), especially in endurance-trained athletes. However, the development of Hbmass and BV and their relationships with VO₂max during childhood are unknown. The aim of the present cross-sectional study was to investigate Hbmass and BV and their relationships with VO₂max in children and adolescents. In addition, the possible influence of endurance training and chronic hypoxia was evaluated. Methods: A total of 475 differently trained children and adolescents (girls n = 217, boys n = 258; untrained n = 171, endurance trained n = 304) living at two different altitudes
