Ferritin is a blood protein that contains iron, and a ferritin test measures the amount of iron in your blood and helps to determine if an individual has iron deficiency. A normal range of ferritin for female is 11 to 307 nanograms per milliliter (ng/ml), but it is estimated that 15-35% of females suffer from iron deficiency with low ferritin levels. When evaluating female athletes, the level of ferritin should be at least 25 ng/ml with more recent research suggesting at least 40 ng/ml for best performance. The demands on a soldier’s body are tremendous. Through sweat, gastrointestinal losses, the menstrual cycle, urine, and the process of foot strike hemolysis; female soldiers will lose iron. With the depletion of iron stores, their body’s ability to deliver oxygen to muscles will decrease and a female soldier’s performance will deteriorate. With the monitoring of ferritin, medical providers can assess the iron stores of female soldiers and provide interventions to achieve their maximum performance. Dr. Marci A. Goolsby, Medical Director of the Women’s Sports Medicine Center at Hospital for Special Surgery explained, “Iron deficiency can lead to subtle changes in an athlete’s performance and lower their ability to push through fatigue.” Furthermore, Cleveland Clinic estimates that up to 35% of female athletes and up to 52% of adolescent female athletes have iron deficiency, and Dr. Caitlin Lewis explains, “Iron deficiency in women athletes is not discussed enough, (and) It’s definitely under recognized in both adults and teens, including anyone who has menses.” This proposed posture abstract is one of the first step in discussing the monitoring ferritin levels of female soldiers and ensuring they are able to achieve peak performance on the battlefield.
