Feeling constantly drained and struggling to perform at your best? For many female athletes, this is a harsh reality, often stemming from a hidden foe: iron deficiency. Take the case of Zara Walters, a Super Netball player who battled fatigue and lethargy for years, impacting her training and overall well-being. But here's where it gets controversial... is this a widespread issue, and what can be done about it?
Zara's story is a common one. She felt heavy-legged, struggled through training, and found it hard to recover. "You're trying to nap every 10 minutes," she recalls. It wasn't until blood tests at the Victorian Institute of Sport (VIS) revealed iron deficiency that she found answers. This wasn't about a lack of fitness; it was a manageable condition.
Maintaining healthy iron levels is a constant challenge for many athletes. Zara now undergoes regular blood tests, works with a nutritionist, takes supplements when needed, and occasionally receives iron infusions. The first infusion was a turning point, she said it was "life-changing".
Why are athletes particularly vulnerable? Iron is crucial for energy production, a strong immune system, and sharp brain function. Exercise can deplete the body's iron stores, making athletes more susceptible. A recent study showed that up to 35% of female athletes are iron deficient, compared to just 5% of the general population.
Dr. Susan White, VIS medical director, attributes this to factors like increased hepcidin (a substance that reduces iron absorption during exercise) and menstrual blood loss, which is common in women.
Targeted Testing, Surprising Results
Three years ago, VIS began proactively monitoring athletes' iron levels. They focused on female athletes, long-distance runners, and those in weight-controlled sports. The results were shocking. While they expected 25-30% of female athletes to be iron deficient, the actual figure exceeded 50%.
VIS developed individual plans, prioritizing a food-first approach with iron-rich foods like red meat, leafy greens, and lentils, followed by supplements, and infusions for severe cases. The time it took to correct the deficiency was also surprising. "We thought we would have them all fixed in 12 months," Dr. White admitted. Instead, it often took 12-18 months to reach optimal levels.
Ongoing monitoring is crucial, as symptoms can be subtle. As Zara explains, "It's a slow build, but I can feel when I am getting a little bit low..." This is when she requests another blood test.
So, How Do You Boost Iron Levels?
VIS's proactive approach is proving effective. They now test athletes during their annual intake and, for those at higher risk, every 3-6 months. Over the past three years, they've administered approximately 30 iron infusions annually, with only three for males (in long-distance sports). "The trend is slowly decreasing," Dr. White notes, "which we hope possibly is an indication of our ability to perhaps pick these up earlier and progress through increasing iron before we get to an infusion." However, infusions carry risks, including allergic reactions and skin staining, and can have anti-doping implications. But when used, athletes and coaches report positive results. "It takes probably a week to start to notice the difference," Dr. White explains. Coaches notice improved training and alertness, and fewer afternoon naps.
No Quick Fix, But Progress
VIS is collaborating with La Trobe University to publish its findings, revealing that iron deficiency is more prevalent and harder to correct than anticipated. With 450 athletes to monitor, it requires persistent follow-up and teamwork. As Zara confirms, "The management of mine has been incredible, and I've been able to live a lot better quality of life, and to train so much better as well."
