Gore et al. 2013, Altitude training and haemoglobin mass meta-analysis

Br J Sports Med 47(Suppl 1):i31-i39. Individual-data meta-analysis, 17 studies, 328 participants. Haemoglobin mass increased 1.08% (95% CI 0.94-1.21%) per 100 hours of adequate hypoxia, for both LHTL and classic altitude, with wide inter-individual variability. The source of the “~1.1% per 100 h” dose-response rule (a looser ~1.33% figure sometimes quoted is wrong). Anchors the well-established mechanism and dose. Strong for the haematological response.
