QUESTION: During a routine physical examination and checkup as part of my
regular sports training program, I was a bit surprised at the news that my
blood test showed a slight anemia
Despite assurances by the doc that there
was little to worry about, I need some explanations
Would you please oblige?

ANSWER: Your doctor is right
This is most probably not dangerous, as
athletes in training normally have lower hemoglobin and serum ferritin (iron)
concentrations than nonathletes
This is not really anemia, but “dilutional
pseudoanemia” (meaning you have more blood volume, with the same number of red
cells), and the condition is beneficial for athletes because it increases
their physical performance.
One of the first adaptations that the body makes to regular exercise is
to conserve salt and water to increase plasma volume
This makes it appear as
if there is less hemoglobin than usual
This cannot harm you because the red
cell mass remains normal
The additional plasma volume improves athletic
performance in that it increases the amount the heart pumps with each beat and
improves the efficiency of sweating
Since dilutional pseudoanemia is a sign
of health rather than sickness, there is no treatment
Runners, however, do
have to watch out for a true form of anemia called “foot strike hemolysis.”
The impact of hard, pounding foot strikes can sometimes destroy normal red
cells in the bloodstream
This can be treated with iron supplements and diet
modification
A well-padded, high-quality pair of running shoes can help
prevent this condition by softening the shock as a runner’s foot strikes the
ground.
