Instances of iron depletion, iron deficiency, and iron deficiency anemia have been observed in male soccer players at rates of around 5–15%42, hence given the absence of a consistent relationship with training load in our study, transferrin is suggested for monitoring iron status in specific players at risk of iron deficiency anemia, particularly when compared with training load and intensity on an individual basis. The gene discussed is TF; the disease is Iron deficiency anemia.
