A) higher iron needs because of greater iron losses.
B) lower iron needs due to enhanced iron conservation.
C) higher iron needs due to greater oxygen delivery to working muscles.
D) lower iron needs due to enhanced iron absorption.
E) higher iron needs because of greater iron losses and higher iron needs due to greater oxygen delivery to working muscles.

Question

Quizplus · Accepted Answer

Athletes who train regularly have higher iron needs because they experience greater iron losses through sweat, urine, and other bodily fluids. At the same time, they also have higher iron needs due to the increased oxygen delivery to working muscles, as iron is necessary for the production of hemoglobin, which carries oxygen in the blood. As a result, both factors contribute to the higher iron needs of athletes compared to nonathletes.
