- Anemia in Athletes

- 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.
