The billions of cells in our body need a continues supply of oxygen. Without oxygen, the metabolic processes cannot occur. An adult takes in about 300 milliliters of pure oxygen per minute while relaxing. Once he starts exercising, the oxygen intake increases. The body adapts perfectly. During exertions one breathes faster and the heart rate goes up.
The body needs a lot of oxygen during endurance sports like running and cycling. The maximum oxygen intake per minute for men is about 3 liters, and the maximum oxygen intake per minute for women is about 2.6 liters per minute. Professional athletes can have an oxygen intake of up to 7 liters per minute. The maximum oxygen intake determines how much oxygen a person can utilize during an exercise. The higher the oxygen intake, the more oxygen is available to the muscles.
The maximum oxygen intake is also known as VO2max. VO2max is the most widely used method to determine a person’s stamina. It is seen as an important factor for performance in endurance sports.
Iron supports the production of red blood cells and hemoglobin. Iron contributes to a normal oxygen transport in the body.
In addition, the mineral is important for the normal energy metabolism and for the reduction of tiredness and fatigue. Iron also contributes to the normal functioning of the immune system and contributes to the preservation of cognitive functions. Therefore it is logical that iron is particularly important in the diet of athletes.
Several groups of athletes should pay extra attention to their iron intake. The iron requirements of professional athletes are higher. Endurance athletes lose more iron through perspiration, feces and urine. An intensive exertion influences the absorption of iron as well. *
Women between the age of twenty and fifty require more iron than men. This difference is caused by blood loss through menstruation. Especially female endurance athletes could benefit from additional iron in their diet. Athletes who follow an energy-restricted diet do not only consume fewer calories, but also have a lower iron intake.
Iron Complex Gold
For a sufficient intake of iron, the diet can be supplemented. Virtuoos’ Iron Complex Gold has been tailored to the needs of (professional) athletes and contains three different iron compounds. One is Ferrochel. Ferrochel is an advanced iron chelate that has been developed by Advanced Albion Nutrition. The iron is linked to amino acids. This product contains vitamin C as well, which supports the absorption of iron from plant sources.
Iron Complex Gold is endowed with the NZVT logo. NZVT is an abbreviation of the ‘Nederlands Zekerheidssysteem Voedingssupplementen Topsport’ (Anti-Doping Authority for the Netherlands.) This certification guarantees the athlete that the dietary supplement is free of doping.
Since December 2012 we are only allowed to publish product data sheets and product information that contain approved health claims by a European scientific organization – as a result of the European regulations on nutrient claims. This limits Virtuoos’ ability to provide information, as many health effects of diets and dietary supplements are (still) not recognized by this organization as sufficiently scientifically substantiated.
