Iron deficiency and athletic training capacity

Before IV iron, Iroh lactate at Optimal wound healing end of Athpetic was the same in both groups, indicating equivalent anaerobic glycolytic capacity between groups. These are collectively referred to as iron deficiency nonanemia IDNA. Endurance sports and intense training increase the body's demand for iron.

Iron deficiency and athletic training capacity -

Sickness, infection, and injury among other things can impact ferritin levels. Often athletes who are concerned about being iron deficient or think that increased iron levels can increase performance will jump immediately to iron supplements.

In extreme cases too much iron can lead to hemochromatosis, which can be deadly 3. The best and safest way to keep an eye on your iron is to get a blood test. Iron should first come from your diet and not supplements.

There are two types of iron sources found in food. Heme and non-heme foods reference the amount of iron that the body is able to absorb from these sources. Heme foods include meat, fish and poultry. Up to 25 percent of the iron found in these foods is absorbed into the body.

Non-heme Iron is found in vegetables and supplements and is only absorbed at a rate of 3 to 15 percent. If your focus is on non-heme foods due to dietary restrictions, or this tends to be where you receive the majority of your iron, focus on getting as much iron from those sources as possible, as well as increasing vitamin C consumption.

Vitamin C helps the body to retain iron and increase absorption from non-heme sources. For athletes, periodizing your nutrition can be an important step in managing iron intake.

Basically a periodized approach to nutrition means that when your training load increases so does your calorie and nutrient intake. Conversely, when your training load decreases you adjust your diet accordingly. One of the things you can do immediately is curb your consumption of coffee, tea and alcohol, as these substances negatively impact iron absorption.

This is especially true when your training load and stress increase. Iron deficiency and iron deficiency anemia can be serious problems for endurance athletes at all levels. The symptoms associated with both of these conditions can be ones that plague athletes for long periods of time if left unchecked.

Runners, and other trained athletes are at risk for a sports-related anemia caused specifically by heavy training. Iron-depleting training effects include mechanical hemolysis physical sheering of red blood cells often seen in runners , intestinal bleeding, hematuria blood loss in urine , and sweating.

Heavy menstrual loss is an additional cause of negative iron balance in female athletes 2. Athletes seeking hypoxic conditions to increase their red blood cell density and enhance endurance performance are at an even greater risk for iron loss 6. This in turn creates an increased demand for ferritin to develop new hemoglobin.

Both male and female athletes have demonstrated reduced serum ferritin levels during training at altitudes between 7, and 8, ft. It is suggested that athletes should check their iron status prior to altitude training, and improve their levels if necessary before undergoing hypoxic conditions 6.

Anemic individuals, in particular, should consider iron supplements beforehand 7. However, athletes attempting to increase their red blood cell count even those with normal iron levels may benefit from a supplement 2 , particularly women, who are at higher risk than men for iron-deficiency 7.

Iron is a mineral that occurs in many foods , such as beef, poultry, seafood, beans, and green, leafy vegetables. Dietary iron is broken down into two types, heme and non-heme 4. Non-heme iron is found in meat products as well, and also in some vegetables, fruits, nuts, beans, and grains 4.

Non-heme iron is also inhibited by calcium, and additionally bran, cellulose fiber , pectin in ripe fruits and vegetables, and jams , phytic acid in grains and beans , and polyphenols cereal, beans, tea, and coffee 1. Consuming vitamin C or meat in the same meal with non-heme iron enhances its absorption.

For persons with iron deficiency, the body also has a built-in enhancement mechanism, which allows for much greater iron absorption than say just adding an orange to your meal 1. These recommendations are considered sufficient for healthy persons as well as non-anemic athletes.

The Cleveland Clinic lists the following foods as great sources of both heme and non-heme iron 9. Due to inhibitors within non-heme iron sources like the calcium in spinach , eating a citrus fruit, yellow bell pepper, or other vitamin C rich food will improve absorption 1.

Athletes in training are advised to pay closer attention to their diets, and consume more iron-rich foods to avoid deficiency 1. The only populations other than IDA athletes that may benefit from an iron supplement are those that are intentionally undergoing hypoxic conditions to increase their red blood cell density 2.

Also, lower iron doses at 39 mg have been shown to cause less gastrointestinal distress in female athletes 1 , which may improve compliance.

It seems that the obvious, and worthwhile intervention for decreasing the number of athletes affected by sports-related anemia is helping them improve their dietary iron intake.

Advising athletes and chronic exercisers - particularly women, runners, and vegetarians - to seek nutrition counseling and regular iron testing 1 , may be the key to preventing iron-deficiency, and the resulting reductions in athletic performance.

Key Roles of Iron Iron plays an important role in energy metabolism. Anemia Having an iron deficiency, or in severe cases, anemia, can be detrimental to athletic performance and overall health. Storage Iron Depletion Iron stores are depleted, but functioning iron is still intact.

Early Functional Iron Deficiency Hemoglobin levels will test normal, but serum ferritin is low nanograms is considered deficient 2. People at Risk for Iron Deficiency In general, people exhibiting the highest risk for iron deficiency and anemia are women, runners, and vegetarians.

Considerations at Altitude Athletes seeking hypoxic conditions to increase their red blood cell density and enhance endurance performance are at an even greater risk for iron loss 6.

All types of iron deficiency may affect physical performance and traniing be treated. The main mechanisms by which sport Irkn to iron deficiency are increased iron demand, elevated iron loss and blockage of iron absorption due to hepcidin bursts. As a baseline set of blood tests, haemoglobin, haematocrit, mean cellular volume, mean cellular haemoglobin and serum ferritin levels help monitor iron deficiency. Treatment of iron deficiency consists of nutritional counselling, oral iron supplementation or, in specific cases, by intravenous injection. Iron deficiency and athletic training capacity
