Introduction. Adequate nutrient intake is essential for achieving optimal athletic performance. Female athletes generally meet macronutrient and micronutrient requirements with the exception of iron [1, 2].Iron is an essential micronutrient in energy production pathways and is a functional component of haemoglobin and myoglobin .Female athletes are considered to be Cited by: There is still debate in the literature on whether or not endurance athletes tend to have low iron stores.
In this article, we propose that endurance athletes really are at risk of becoming iron deficient due to an imbalance between absorption of dietary iron and exercise-induced iron loss. The purpose of this article is to present a critical review of the literature on Cited by: The purpose of this investigation was to examine the effects of oral iron supplementation on endurance performance in initially iron-depleted, nonanemic female distance runners.
Eighteen iron-depleted (serum ferritin less than 20 -1, hemoglobin greater than or equal to 12 -1) women ( yr) performed a VO2max test and an endurance Cited by: The aim of the present study was to investigate the association between the HFE H63D polymorphism and elite endurance athlete status in Japanese and Russian populations, aerobic capacity and to Author: Diane M.
Dellavalle. Effect of iron supplementation on endurance capacity in iron-depleted female runners. Med. Sci. Sports Exerc., Vol. 24, No. 7, pp. –, The purpose of this investigation was to examine the effects of oral iron supplementation on endurance performance in initially iron-depleted, nonanemic female distance runners.
Supplementation. Iron supplementation may be a necessity for some athletes in addition to a sound, iron-rich nutrition program. For those with clinically diagnosed iron deficiency anemia, it is important to focus on eating foods high in iron along with taking an iron supplement.
However, low energy intake, vegetarian diets and endurance exercise have also been proposed as potential factors impacting both male and female athletes' iron stores (Castell et al. Iron is a functional component of oxygen transport and energy production in 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 Cited by: female college athletes. Iron is required for optimal athletic performance and health because of iron’s essential roles in carrying oxygen and as cofactors in other enzymes related to metabolism and immunity.
A low iron status with or without anemia can decrease endurance, muscle function, and work capacity. IronFile Size: KB. Iron and the Endurance Athlete (1) August 6, work capacity, reduced VO2max—and this effect is reversed when iron supplements are taken. But here is where the message of iron seems to get confused to the point that athletes now often wonder if taking iron can improve performance regardless of current iron status.
Iron Supplementation Author: Trainingpeaks. Women who take iron supplements experience a marked improvement in their exercise performance, a new study shows. Iron supplementation improved women's exercise performance, in terms of both the.
Iron deficiency is prevalent among endurance athletes, particularly females. Low iron may compromise oxygen delivery and physical performance. Vegetarianism, desire for convenience, and perceived health risks associated with red meat contribute to low bioavailable iron intakes.
The purpose of this study was to examine if lean beef supplementation would maintain iron Cited by: 7. Iron is one of the most abundant mineral on earth and is essential to normal human physiology. About 2/3 of the body’s iron is found in hemoglobin, the protein in red blood cells that carries oxygen to cells.
An adequate supply of iron is necessary for the body to produce hemoglobin and red blood cells. If too little iron is available, fewer and/or smaller RBC’s are produced, leading. The improvement of iron status due to iron supplementation has been accompanied by an improvement in endurance capacity [23, 24].
In young elite athletes with normal Hb concentrations, the return of low Ferr to normal values following supplementation of mg/day of elemental iron for 12 weeks, even in the absence of increased erythropoiesis Cited by: 7. Iron supplementation group demonstrated significant changes in VO 2 max and in oxygen consumption in a maximal accumulated oxygen test IDNA and Athletic Performance Dellavalle and Haas collegiate level female rowers Objective was to investigate the impact of iron depletion without anemia (IDNA) on performance indicators.
As we’ve already indicated before at Peak Performance, iron problems and female athletes are as closely linked as Westminster Abbey and Big Ben. In Great Britain and the United States, about 30 per cent of adult women and 40 per cent of adolescent women are iron deficient, while around 6 per cent of both groups suffer from true iron-deficiency anaemia.
Among endurance athletes, iron deficiency and iron deficiency anemia are far more prevalent. A study in the Journal of Pediatrics found that 34% of female and 8% of male high school cross country runners had serum ferritin levels below 12 ng/mL.
2 Another study in the Journal of Adolescent Health Care found similar results. A study of female collegiate rowers in New York state found 10 percent were anemic and 30 percent had low iron stores. (Anemic refers to low hemoglobin, for which the most common reason is.
Introduction. Endurance athletes are prone to negative changes in iron status caused by insufficient dietary intake, increases in haematuria, gastrointestinal bleeding, sweating and haemolysis.1 The effect of depleted iron stores on athletic performance depends on the severity of the iron deficiency, with the most severe cases impairing erythropoiesis (iron Cited by: 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.

Med. Sci. Sports Exerc. 24 Crossref ISI Cited by: This puts endurance athletes, such as long distance runners, at risk of iron deficiency. Without enough iron, can’t use oxygen properly to produce energy.
This impairs any athlete’s ability to. Trained athletes frequently experience low levels of blood haemoglobin (13 to 14 g/ml in men and 12 g/ml in women) plus low haematocrit and low ferritin levels. These parameters define the concept of ‘sports anaemia’.
Low iron levels may be due to mechanical haemolysis, intestinal bleeding, haematuria, sweating, low iron intake or poor intestinal Cited by: lar risk for developing iron deficiency, such as pre-menopausal, physically active females (12).
The purpose of this case study was to determine the effect of long-term (16 weeks), low-level iron supplementation on thyroid hormone concentration and RMR in two iron-deficient-anemic college-age female athletes. Although a case. Athletes, particularly menstruating female endurance athletes, need to be extremely mindful of iron intake in order to meet their bodies’ demands.
Those following a strict vegetarian or vegan diet can be at even higher risk for iron deficiency due to the decreased absorption of non-heme iron found in plants and fortified on: Hale Parkway, Suite Denver, Colorado USA. Iron is considered essential; that is our body cannot manufacture it and it must be consumed via diet or supplementation.
Iron coming from dietary sources is absorbed in the small intestine. It has been documented that only about 10% of.

A small study of 37 female volleyball players, 17 of whom were categorized as having latent iron deficiency and 20 others who had iron deficiency anemia showed that daily iron supplementation over a period of two months created a small but statistically significant improvement in VO2 max in the iron deficient group but not in those at risk for.
The specific aims of the current study were: 1) To determine the prevalence of IDNA in a sample of female rowers at the beginning of a training season; 2) To determine how IDNA affects endurance training and performance at the beginning of a training season; 3) To determine how iron supplementation affects iron status, training and performance in IDNA.
Iron is essential for the health of your blood, but too much of it is toxic. As a result, many experts caution against iron supplements and diets high in iron.
A recent research review in the Journal of Strength and Conditioning Research offered some insight into iron supplementation in athletes, particularly : Doug Dupont. How to get rid of muscle knots in your neck, traps, shoulders, and back - Duration: Tone and Tighten 2, views.
Some studies support an adverse effect of compromised iron status on aerobic capacity (VO2max), endurance and work performance in humans (5,9). For example, in a study by Zhu et al., an iron depleted group of women (with no anemia) had significantly lower VO2max scores than a group of women with normal iron status.
Iron in sweat represents the major route of iron loss from the body Iron losses occur from accelerated destruction of fragile, older blood cells Iron deficiency affects a higher percentage of male athletes than female athletes Sports anemia is successfully treated by increasing dietary iron to levels times the RDA.

Supplementation of proteins, carbohydrates,2 lipids,3 vitamins,4 and trace elements have been studied and reviewed for their effect on athletic performance in power and endurance sports.5, 6, 7 The focus of this article is to summarize current knowledge of the adaptive changes in iron metabolism of athletes during training and to review Cited by: female athletes, and we hypothesized that a combination of iron supplementation and nutritional counseling would result in optimal health outcomes.
MATERIALS AND METHODS. Subjects. Thirty female college students (mean age: ± years) who participated in a competitive sport and complained of. anemia symptoms were recruited. THE EFFECT OF STRENGTH TRAINING ON PERFORMANCE IN ENDURANCE ATHLETES 1. INTRODUCTION Endurance sport performance relies on a complex inter-play of physiological and biomechanical factors.
Cardiovascular capacity has often been thought to be the main limiting factor in endurance performance. Classical measures such as maximal oxygen uptake (VO 2 .These results suggest that the female runners who consumed a modified vegetarian diet had non-anemic iron deficiency, which could reduce endurance capacity.
While female athletes, the group most vulnerable to iron deficiency, were investigated in this study, the iron status of male athletes has not been addressed, yet. Left untreated, iron depletion can develop into iron deficiency anemia (IDA), which impairs the body’s aerobic processes, brain and muscle metabolism, endurance performance, and normal immune response.
Iron, a key factor in aerobic capacity and thus directly linked to sports performance, is necessary for producing hemoglobin and myoglobin.
