Muscle-damaging e. eccentric exercise should not be completed in the days prior because this increases inflammation. Therefore, the measurement may reflect the stress or inflammation and not an iron deficiency.

Illness — the athlete should be showing no signs of illness or infection. There are different stages of iron deficiency. The most severe state is iron deficiency anemia IDA which results in a host of symptoms, including weakness and fatigue.

Two earlier stages can be identified that are precursors to IDA. These are collectively referred to as iron deficiency nonanemia IDNA. The first and least severe stage of iron deficiency is marked by a fall in serum ferritin resulting from a reduction of total body iron stores, but other iron indices such as haemoglobin remain normal This stage is called nonanemia.

The second stage, also non-anemia, is marked by low serum ferritin but also low serum iron or decreased transferrin saturation and increased total iron binding capacity TIBC. Once iron stores and transport iron have been sufficiently depleted, the body can no longer keep up with the demands of hemoglobin synthesis, and the third and final stage IDA results.

Peeling et al. These are:. See infographic for the cut-off values used for each stage. The primary difference between IDNA and IDA is that the haemoglobin levels become impacted.

Once this occurs, it can start to impact exercise capacity because the body is not able to deliver oxygen around the body as efficiently.

It is a good idea to plan periodic testing of iron status with your sports physician, especially if you are female, vegetarian, have a high training volume and are involved in endurance sports.

Transdermal patches represent another option for bypassing the GI tract although the literature and formulations thus far have failed to show much benefit McCormick Lancet Haematol.
Iron Depletion - Sports Dietitians Australia (SDA) Athletes, particularly female athletes participating in endurance sport, are at increased risk of compromised iron status due to heightened iron losses through menstruation and exercise-induced mechanisms associated with endurance activity. The mechanical force of a footstrike during endurance running, for example, can increase the destruction of red blood cells in the feet, leading to a shorter red blood cell life span. Even so, our bodies only absorb a small portion of the iron we eat. Your Cart items item items. Symptoms include fatigue and shortness of breath and athletes will exhibit a decline in performance.

Dietary iron is difficult to replenish even in the non-athlete. This puts vegetarians at increased risk of ID Björn-Rasmussen Treatment is primarily aimed at iron supplementation and is generally an oral route. Indications for treatment are any degree of anemia and ferritin below normal cutoffs.

The biggest side effect is gastrointestinal distress which makes compliance challenging Tolkien The best available evidence says that to avoid this GI toxicity, athletes should take mg every other day and will still have a similar increase in iron stores with less total iron ingested McCormick To maximize absorption, athletes should consume their supplement in the morning, 30 minutes prior to exercise to help potentiate absorption McCormick There are other oral formulations which are less commonly used but may be promising for future management.

Answer A is the correct answer. This vignette is most consistent with iron deficiency anemia. The fatigue and decreased performance could be attributable to any of the answers. A normal blood glucose excludes diabetes.

Overtraining syndrome and relative energy deficiency in sport are unlikely given the correct calorie intake, no changes in her training, no other stress related injuries and a normal body habitus.

Her symptoms, sport of choice, gender and choice of veganism put her at high risk of iron deficiency. Because of the decrease in performance and fatigue she is likely anemic at this point. The patient needs serum hemoglobin and ferritin levels checked and perhaps a further workup if the diagnostic picture is unclear.

There is a direct correlation between iron stores, arterial oxygen content and maximal contractility of skeletal muscle. Ferritin is a storage protein which accurately reflects total body stores of iron and is a reliable marker of iron deficiency. It is worth noting that ferritin is an acute phase reactant which can be elevated following exercise or other inflammatory conditions.

Hepcidin is a hormone which regulates iron metabolism. Hepcidin increases following exercise and while elevated, impairs iron absorption in the gastrointestinal mucosa Peeling Image 1.

Athletes are considered more susceptible due to increased iron requirements. This is primarily due to hematological adaptations to training and sport requiring an increased oxygen demand.

Iron loss can also occur due to sweating, hematuria and GI bleeding which may seem insignificant but can be cumulative over time Gaudin Foot strike hemolysis has also been implicated. In women, blood loss from menstruation Fallon and decreased iron consumption have also been cited as contributing factors Nickerson Iron deficiency non-anemic athletes typically are asymptomatic.

When anemia is present, athletes will report lethargy, fatigue, weakness and shortness of breath. They will often note a decline in exercise performance, reduced work capacity and inability to adapt to training stress Haas Physical exam may be normal.

Pallor of skin and conjunctiva may be present but is not a reliable clinical indicator in mild anemia. Although exact iron requirements for athletes are currently unknown, they are most likely higher than the non-athlete and a conservative recommendation would be to at least meet the Australian Recommended Dietary Intake RDI.

Recent evidence suggests that even early stages of iron depletion can reduce performance capacity, particularly during aerobic activity. If untreated, low iron levels can develop into iron deficiency anaemia which can leave athletes feeling lethargic and unable to perform at their best.

glandular fever. Iron is a hot topic for athletes, particularly endurance athletes who have fatigue. But iron deficiency in women is not always straightforward to diagnose or treat. Tenforde, who has extensively researched iron and athletes , explains iron deficiency causes and effects.

Poor oxygen transport can make you feel tired and out of breath. Tenforde says. Your body absorbs iron through your small intestine. So gut issues may prevent absorption of iron and other nutrients. Low iron can seriously affect your energy levels and endurance. The effects on athletic performance depend on how iron deficient you are, what other conditions you have, and your level of fitness.

Diagnosing iron deficiency can be tricky because ferritin levels may falsely test as normal, high, or low. There are many reasons for this. Illnesses and infection can cause temporarily elevated ferritin, for example. A normal ferritin level can falsely suggest ferritin is within a normal range—but this does not mean the ferritin level is appropriate for an athlete to feel well.

People who are menstruating need 18 milligrams of iron per day, according to the National Institutes of Health. And people who have iron deficiency need more iron than the standard recommended amount.

Hemochromatosis causes toxic amounts of iron to build up in your body. There are also other reasons to work with your health care provider while taking iron supplements. For example, too much iron can cause painful stomach cramps.

You should take iron supplements only under the care of your provider.

Arhletes, particularly deficiendy Iron deficiency risks for athletes participating in endurance sport, are at increased risk of compromised iron status due to heightened iron losses through menstruation and exercise-induced mechanisms associated with endurance activity. However, this approach has been criticised because of the side effects and increased risk of iron toxicity associated with the use of supplements. Thus, more recently there has been a growing interest in using dietary modification rather than the use of supplements to improve iron status of athletes. Although studies using dietary modification are still scarce, current literature suggests that dietary iron interventions can assist in maintaining iron status in female athletes, especially during intensive training and competition.
