What is a potential consequence of iron deficiency in female athletes?

Iron deficiency in female athletes can lead to increased fatigue and poor oxygen transport due to the critical role iron plays in the formation of hemoglobin, which is essential for transporting oxygen in the blood. When iron levels are low, it affects the body's ability to produce sufficient hemoglobin, resulting in reduced oxygen delivery to muscles and tissues during physical activity. This lack of oxygen can lead to feelings of tiredness and decreased athletic performance, as the body struggles to meet the energy demands of exercise.

The other options refer to different health issues. For instance, reduced muscle mass primarily concerns inadequate protein intake or overall caloric deficiency, rather than iron specifically. The risk of dehydration is more directly related to fluid intake and loss rather than iron levels. Lastly, lower risk of fractures does not relate to iron deficiency at all; in fact, iron deficiency can contribute to an overall decrease in health and performance, thereby potentially increasing injury risk.
