Background Endurance athletes have been using altitude training for decades to improve near sea-level performance. The predominant mechanism is thought to be accelerated erythropoiesis increasing haemoglobin mass (Hbmass) resulting in a greater maximal oxygen uptake (V¿O2max). Not all studies have shown a proportionate increase in V¿O2max as a result of increased Hbmass. The aim of this study was to determine the relationship between the two parameters in a large group of endurance athletes after altitude training. Methods 145 elite endurance athletes (94 male and 51 female) who participated in various altitude studies as altitude or control participants were used for the analysis. Participants performed Hb mass and V¿O2max testing before and after intervention. Results For the pooled data, the correlation between per cent change in Hbmass and per cent change in V¿ O2max was significant (p
