3 Things You MUST Do If You Are Iron Deficient (For More Energy!)Exercise-induced iron deficiency -
c at Western Australian Institute of Sport. Vegetarians and women with heavy periods are at greater risk of low iron and anemia. The primary symptoms of iron deficiency anemia include:.
According to the National Institutes of Health NIH , most adult men need 8 mg per day; most women not pregnant or lactating need 18 mg daily. Good dietary sources of iron include are red meat, dark poultry like chicken thighs , beans, nuts, dried fruit, whole grains, fortified breakfast cereals, and most dark-green leafy vegetables, such as kale.
You can improve your iron absorption by eating foods rich in vitamin C , like citrus and bell peppers, with a meal. Calcium from dairy foods and tannins found in tea can decrease absorption. One Drink Before Bed Sabotages Sleep Quality. Strength Training Boosts Performance, Study Says.

In this study, the serum ferritin reduction was paralleled by significantly higher levels of something called serum transferrin receptor sTfR concentration.
However, research has indicated that you can actually be iron deficient in the tissues without being diagnosed as iron anaemic. sTfR, however, is a highly sensitive indicator of tissue iron status.
When cells require more iron, they signal this need by increasing the number of transferrin receptors on their surface.
A small portion of these receptors come off of the cell surface and are carried into the bloodstream, and these are the levels that are measured. A high sTfR is, therefore, related to iron deficiency at a truly fundamental level — within the cells or tissues. A significant body of evidence is accumulating that a low tissue iron status, without a corresponding low blood haemoglobin level, impairs endurance performance.
Indeed, scientists now believe that tissue iron deficiency without anaemia can actually blunt the training adaptations that occur following endurance training.
One study gave 41 iron-depleted, but non-anaemic, female subjects a twice-daily iron supplement or a placebo for six weeks. As expected, iron supplementation significantly improved several markers of iron status, including serum ferritin, transferrin saturation and sTfR concentrations, yet this occurred without affecting blood haemoglobin concentrations.
Conversely, in women with sTfR levels below 8mg per litre, there was no significant benefit of iron supplementation. Iron is also difficult to absorb and can be depleted by endurance training, compounding the problem, especially for younger female triathletes.
The most solid advice is to assess your risk for iron deficiency, consume an iron-rich diet and consider taking an sTfR test. A blood sample is required to test for an iron deficiency.
Considerations should be given to 2 :. The time of day — morning is preferable. Hydration — athletes should be well hydrated. Prior exercise — hours rest from exercise prior to the blood sample is preferable.
If exercise is necessary, then only low to moderate intensity exercise should be completed in the 24 hours prior. 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. In the next blog we will discuss how iron deficiency can be prevented or treated.

Iron is a functional component of oxygen Exercise-induced iron deficiency and energy production Exerccise-induced humans and therefore is a critically important micronutrient for sport and exercise performance. 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. However, this approach has been criticised because of the side effects and increased risk of iron toxicity associated with the use of supplements.

This reduction of iron shows up in the blood work as low hemoglobin, a decreased RBC count, or a hematocrit tending toward the lower end of the normal range. The reason most people are left flummoxed by the condition is that it appears in fit and healthy individuals that see regular exercise either as a part of their daily regimen, professions, or as dedicated hobbies. A variety of causes are attributed to sports anemia, however, there does not exist a conclusive consensus on the causes of sports anemia.
