Anyone ever heard of the term sports anemia? I have a couple of athletes who have this happen. Basically the hemoglobin and hematocrit levels are low but the reason is because of the great increase in plasma volume. Or at least that's my understanding of it. I was concerned at first when I got the blood results back (mid 13 to 14.0 hem and 40ish hematocrits) but in doing some research it seems that the increase in plasma volume offsets the deceptively low hemoglobin and Red blood cell levels.
Any thoughts or should I have more blood tests done on the runners.
