Document Summary
Anemia interferes with oxygen uptake and delivery. Without adequate oxygen cells less aren"t able to do oxidative metabolism therefore, more use of non oxidative glycolysis use glycogen faster glycogen depleted fatigue other symptoms: fatigue, intolerance to exercise. Anemia especially common in women more than men. Why: eat less food than men, diets lower in iron, requirements are higher in women. Also more common in athletes but this is called false anemia . Why is that: false anemia due to increased plasma volume, adaptation to training, oxygen delivery is fine, also called sports anemia . Why would athletes have higher rates of true anemia: footstrike hemolysis. Force of running causes rbcs to break reduces the number of rbcs in circulation: exertional hemolysis. Breakage of old, fragile cells by hitting artery walls. Not related to footstrike since blood moves 5-6x faster than at rest during exercise. Symptom #1: fatigue viz. non specific, crosses over with:
