Iron deficiency and injury risk in athletes -

Getting Enough Iron For many, the fix for iron deficiency is as simple as consuming more iron-rich foods. The best sources of iron include beef, fish and poultry. Vegetarians can find their daily dose of iron in quinoa; beans; lentils; dark, leafy greens or raisins among other options.

Some breakfast cereals and breads also carry a fair amount of iron— though remember, the calcium in milk inhibits the uptake of iron. Even with an iron-rich diet, some people may need to take supplemental iron. A study in the American Journal of Clinical Nutrition found that among highly trained female distance runners, the iron deficiency rate is 82 percent, even though 75 percent of the athletes studied were fulfilling their dietary recommendations for iron.

Thompson recommends taking liquid iron with a shot of orange juice and a mg vitamin C pill to ensure maximum absorption. He also recommends that athletes supplement 30 minutes prior to a meal so as to avoid consuming calcium near supplementation, as calcium blocks the absorption of iron.

Consult a doctor before taking supplemental iron: the amount your body needs will vary based on your individual iron levels, which should be retested every three to four months. Supplementing your iron when you have normal iron levels can carry some serious health risks.

More Challenge. Treatment involves oral supplementation of ferrous sulfate mg. The best available evidence says to use alternate day dosing to avoid the GI distress and to take it in the morning, 30 minutes before exercise to maximize absorption.

PLoS ONE. BUT, the ideal world does not exist. The only real way to know if your levels are "optimal" for you and not just in the "normal range for the general population" is to have a course of iron therapy with pre and post blood tests.

If you find your haemoglobin Hb count rises from to say , with treatment both these levels being within the "normal range" for a young woman , and you find that you feel aerobically much fitter and your performance is better, then that increment in your blood count, which is the equivalent of an extra litre of oxygen carrying capacity, is probably responsible.

In the meantime, your iron "stores" as measured by your "ferritin" levels may have also increased from 20 to 50, again both in the "normal" range as quoted by the labs for the general, mostly sedentary population.

For what its worth, the levels that I use, which are considerably higher than what the labs use as lower limits of normal for these tests, are an Hb of and ferritin of 30 for a female athlete, and an Hb of and a ferritin of 50 in a male athlete.

For athletes whose levels are below the above mentioned, who are struggling to find "their form", and in whom there is no obvious medical diagnosis to explain their fatigue, I recommend a trial of iron supplementation.

The aim being to try and get them up to their optimum level or see if they are already at their optimum. Dietary assessment is hugely important and this has been covered in previous issues but to reiterate, a "several day dietary recall" is useful to see just what the average daily intake is.

Diet alone is pretty slow in resolving significant iron deficiency so supplements pills are usually necessary to help bring levels up or see an effect more quickly. In some women, who absorb iron even more poorly than most, and who have a very slow or minimal response to iron medication by mouth, there is I believe justification for intramuscular iron injections.

Once again this is a contentious issue medically because there have been no controlled studies showing that this works better than tablets but anecdotally there is no doubt in my mind. There are risks with iron therapy intramuscularly, but these are very rare and far less common than risks associated with far more frequently used medications.

It usually results in significant increments in both scores "quickly" which gives them the benefit of training at their optimum blood count and iron levels, and they will quickly tell me whether they feel any different or not.

It then is important to make sure the improved status is maintained with serial blood testing. Not all fatigue however is iron deficiency.

Not infrequently, athletes presenting with fatigue may have undiagnosed asthma, underlying viral or another infection they were not aware about, or other conditions like an overactive or underactive thyroid, heart disease, high blood pressure, diabetes, kidney disease, depression or even cancer.

Every athlete presenting with fatigue needs a full work-up with a full history of their fatigue, clinical examination, and blood tests before assuming that overtraining is the culprit - it however often is!

Iron deficiency is frequent among athletes. Ion types of iron deficiency Anti-cancer diet plans affect physical injurh and should be treated. The main mechanisms by Iron deficiency and injury risk in athletes athletew leads athletees 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. Athletes with repeatedly low ferritin values benefit from intermittent oral substitution.

Iron deficiency and injury risk in athletes -

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.

Iron Deficiency ID Iron deficiency and injury risk in athletes a defixiency of deficiencg common in athletes, especially among jn and those that participate in endurance andd. There are two eisk of ID: iron Determining water quantity non anemia Ihdefined by decreased iron stores, and Arthritis exercises for energy conservation deficiency anemia IDAwhich is defined by a drop in iron stores and hemoglobin. Generally speaking, this is due to iron losses exceeding iron intake and absorption. Early on in the disease, athletes will have ID with normal hemoglobin levels, while in later or more severe phases of the disease they will develop IDA.
