Training with low blood counts(3 posts)

Training with low blood countsBruno S

Hello, I am a 28 year old male that five years ago was diagnosed with Hodgkin's disease and treated with chemo and radiotherapy. As a result my blood counts are lower than those of a normal person. I have 36
for my hematocrit and 12.8 for my hemoglobin. My doctors have told me that my condition is not too severe and that I can live a normal life with these blood counts. I have been cycling intensively for the last
two years. I am not planning to race but I would like to know how much this condition impacts my performance, as I suspect it does. Anyone's input or advice will be greatly appreciated.

In the summer time, if I am not getting enough salt in my diet or it's very hot and I am drinking a lot, sometimes my hematocrit drops below 38 (the minimum required to donate blood). It normally runs in the low-mid 40s. It's hard to separate the effect of the heat from that low Hct. However, if I donate blood and I ride a 10 mile TT, my time slows by about 2.5%. I think this is probably the range you're working with. That's about 0.6 mph. I would think this would be worst case, and that is a speed differential going flat out. The delta would be smaller at a more moderate pace.

I can perfertly ride long distances like centuries and I have good sprinting power but what its very difficult for me is to ride at my lactic acid threashold like its done in races. Its not a problem maintaining my pulse at that level but my power just fades after a few minutes. Its like my muscles do not receive enough oxigen and just shut down. After a short rest I'm ok again.
