    Increase in Hb mass after alitude training in elite junior athletes

    Dear Editors,

    Dres. Gore and Hahn suggest that the significant mean increase of 6% in total haemoglobin mass (tHbmass) which we observed after altitude training in elite junior swimmers might to a major extend be attributed to few erroneous measurements after altitude training. As already discussed in the paper, we agree that an increase of about 24% is astonishingly high. However, as pointed out, we were not the...

    Why such large increases in Hb mass?

    Dear Editors,

    The altitude training study of Friedmann et al. reported a 6% increase in haemoglobin mass (Hbmass), but this result warrants close scrutiny, particularly without a corroborating measure of augmented VO2max, nor of corresponding measures in a matched control group. The authors’ contend that “there exist no studies in which the changes in total haemoglobin mass following treatment with recombinant...
