　　This short paper explores the extent to which haemoglobin mass (Hbmass) is a viable technique to monitor accelerated red blood cell production at moderate altitude in elite athletes,since the within subject variation of Hbmass is ~4% for measures take a few months apart.For a sufficient dose of natural or simulated altitude,which is approximately >2000m for > 12 h/day for 2-3 weeks,Hbmass will increase by~3% in our hands,but we have also quantified that the individual responsiveness of Hbmass to repeated doses of hypoxia is nearly the same magnitude.Performance responses to an altitude camp are typically 1-2% but,again,we also have quantified that individual responsiveness is of equal magnitude (1-2%).Our data suggest that scientists,coaches and athletes need to be aware that individual response to altitude are of similar magnitude to the noise of the measure; and it is to be expected that individuals may not respond in the same manner to each altitude exposure.
